Caloric restriction has been studied resyriction the context of historical food balancec, long-term lifestylecalpric, and animal studies, all of which have shown promising effects with respect to aging and metabolic health. There does not seem to be a caloric restriction method that poses more benefit over another method.

Thus, the best method depends on the needs of the individual. The Difference Appears Minimal Between Time-Restricted Eating and Caloric Restriction. In a small-scale trial on participants, the differences between caloric restriction achieved either through dietary calorie control or time-restricted eating were minimal.

Participants who limited consumption between 8 am and 4 pm lost 8kg on average over the course of a year, whereas those who limited their calorie intake lost 6. All other health outcomes were similarly beneficial.

When the timing of food is accounted for, the differences in the above restricttion are negligible. Short-Term Fasting and Caloric Restriction Benefits Proved Similar.

Fasting on alternate days zero calories for days; normal consumption every other day proved to promote the same benefit as a continuous caloric restriction in young to middle-aged adults.

Despite this difference, there was no compensation in eating habits once normal consumption resumed in alternate day fasting. Intermittent Fasting or Time-Restricted Eating Can Be Easier to Implement.

Despite these findings, precise caloric restriction is often more difficult to implement safely than time-restricted eating or intermittent fasting.

Most people are not prepared to measure their nutrient intake or count their calories, and the process is prone to miscalculation. Long-Term Consistency Promotes Better Metabolic Stability. While the results are comparable across studies for different types of caloric restriction diets, consistency is vital for reaping the long-term benefits.

In trials that lowered metabolic rate, it has been observed that participants often compensated behaviorally by engaging in less physical activity. After years, the metabolism eventually stabilized, and participants were engaging in their usual activity levels while consuming fewer calories.

Intermittent fasting and time-restricted eating are prone to similar metabolic fluctuations that can affect physical activity levels until sufficient time has passed for the metabolism to fully adjust. Caloric restriction is generally regarded as safe if carried out in the absence of malnutrition.

Caloric restriction ought to be undertaken in the context of a nutrient-dense diet containing adequate protein, fats, carbs, and micronutrients to sustain health and well-being. What is Caloric Over-Restriction? It is not certain at what point restricting calories would lead to starvation, provided the diet still contained balajced nutrition.

Other Safety Considerations. Physical activity levels should also be considered with regard to caloric restriction, as well as current calorie intake.

A healthy diet plan is often low in calories, and may not require a further restriction of calories. Individuals who engage in frequent physical activity and who consume a nutrient-dense diet likely already meet the baseline requirements of caloric restriction as a practice and are likely already receiving the benefit.

Side Effects. Without adequate nutrition, caloric restriction is not conducive to health and tends to promote starvation in the long run. Chronic over-restriction of calories and long-term starvation can result in the following side effects:. Caloric restriction is not a recommended practice for any individuals with the following conditions:.

The concept of caloric restriction can be applied in any of the above ways intermittent fasting, time-restricted eating, or calorie counting and reduction. The conventional Caloricc demands counting calories and limiting their intake without compromising adequate nutrition.

This is based on age, height, weight, and physical activity levels. The average recommended caloric consumption for men is around per day and per day for women. Non-essential plant-based nutrients have been found to be responsible for the health-promoting benefits of whole foods.

They are present throughout the diet, mainly in fruits, vegetables, legumes, herbs, spices, whole grains, nuts, and seeds.

All antioxidant phytochemicals are typically consumed in tiny amounts, averaging a few hundred micrograms to several milligrams per day. While their quantities are minimal and even less in processed foodstheir collective dietary presence and benefit have been shown through epidemiological studies linked with optimal health, longevity, inflammation control, and a reduced risk of acquiring disease.

In animal and other studies, most of these plant-based nutrients failed to extend lifespan in short-term trials alone. However, their effects appear to enhance the longevity-promotion effects of caloric restriction, making them complementary. While it might seem counterintuitive, physical activity is a necessary component in balancing metabolism and promoting longevity.

Physical activity appears to be one of the only factors capable of increasing energy expenditure, metabolic rate, and longevity. Caloric restriction in itself helps to reduce the energy expended during physical activity.

Inconsistent Caloric Restriction Can Lower Physical Activity Levels. It has been observed that after six months to a year of caloric restriction, physical activity levels decline, possibly as a form of compensation for reduced energy intake.

However, after two years, this effect seems to normalize, and activity levels increase back to baseline. Therefore, caloric restriction should probably not be used as a short-term strategy for optimizing energy levels as it may promote reduced physical activity. In the long term, caloric restriction can enhance physical activity by increasing available ATP energy and lowering bodily energy requirements via body mass reduction.

Exercise Consistency Better Enhances Caloric Restriction Benefit. A handful of studies show that the resting metabolic rate is slightly elevated after acute exercise due to changes in oxygen uptake. These effects do not appear to be carried forward with consistent, long-term exercise, wherein resting metabolic rate remains largely unaffected after engaging in physical activity.

While there is no ultimate cure for aging, it would seem that extending our mortality may be as simple as processing less on a daily basis.

Restricting calories is able to lower the metabolic rate and significantly enhance energy production, with noticeable long-term benefits on health and the quality of aging. Unprocessed, plant-based whole foods and physical activity offer complementary benefits to that of caloric restriction through promoting optimal energy metabolism.

The Benefits of Being in a Calorie-Deficit Diet

However, very high calorie foods, such as large muffins or slices of cake, can make it difficult to stay under 1, calories for the day while maintaining nutritional needs. Eliminating empty calories from the diet can free up more space for treats.

Some sources of empty calories include:. A calorie deficit is one of the most important factors for weight loss. However, other factors, such as meal timing and the type of food someone eats, will also contribute to weight loss. Weight loss may not happen the same way for every person.

Some people may lose weight faster than others or benefit from different methods. It may also be difficult to consume all necessary nutrients on very low calorie diets. People can work with a healthcare professional to ensure they are eating a balanced diet while still achieving a safe calorie deficit.

Reducing the number of calories a person consumes can help them lose weight. Low calorie diets may also reduce the risk of certain diseases, such as diabetes. However, weight is not the only or best measure of health. A person will not necessarily become healthier merely by losing weight.

A doctor or dietitian can help a person plan a custom diet and safe nutrition plan that offers a balance of nutrient-dense food alongside occasional treats. A person on a calorie diet eats only about a quarter of the recommended daily intake.

This may be beneficial for some people, but also comes with…. Weight management and loss seems like a difficult health measure to get right, but keep a close eye on the number of calories you consume can help….

Medically reviewed by Natalie Butler, R. Many experience better control over blood sugar levels, reduced blood pressure, and healthier cholesterol profiles.

This can significantly lower the risk of metabolic diseases like diabetes and heart disease. On a deeper level, calorie restriction can promote cellular repair processes. This includes autophagy, where cells cleanse themselves of damaged components, potentially slowing down the aging process.

Calorie restriction can strengthen the immune system, making you more resilient against infections and diseases. It often reduces inflammation, a key player in many chronic conditions. Over time, many report improved physical endurance. This is possibly due to better energy utilization and reduced oxidative stress.

Changes in calorie intake can positively influence hormone levels, such as reducing insulin and IGF-1, which are linked with aging and cancer risk. Improved sleep is a common benefit, likely due to factors like reduced body weight and decreased inflammation. Understanding these aspects can help you navigate calorie restriction safely and effectively.

One significant risk of calorie restriction is the potential for nutritional deficiencies. Here are some key areas to consider:. Being aware of these potential impacts helps you approach calorie restriction with caution, ensuring you maintain a healthy balance and support your overall physical well-being.

Calorie restriction can lead to several metabolic changes in your body, some of which are important to be mindful of:. Certain groups should exercise particular caution with calorie restriction due to specific risks:. Calorie restriction, despite its challenges, comes with a host of benefits that can significantly improve your health and well-being [ 5 ].

Weight management is a central benefit of calorie restriction. By consuming fewer calories than your body burns, you promote weight loss.

This approach is straightforward and can be particularly beneficial for those battling obesity. Unlike quick-fix diets , calorie restriction can help you maintain a healthy weight over the long term. By focusing on gradual and sustainable calorie reduction, calorie restriction helps you avoid the common trap of yo-yo dieting , where weight is rapidly lost and gained.

Calorie restriction can significantly improve metabolic health , which is crucial for overall well-being. Many find that calorie restriction helps lower their blood pressure, reducing the risk of heart disease. These metabolic improvements are key to preventing a range of chronic diseases and enhancing your quality of life.

Calorie restriction not only benefits the body but also has a positive impact on brain health. Many people experience improved focus and memory when they reduce their calorie intake. This is thought to be due to decreased inflammation and oxidative stress in the brain. Some individuals notice an uplift in their mood.

A balanced diet with controlled calories can contribute to better mental health and emotional well-being. These brain health benefits highlight the holistic impact of calorie restriction. Calorie restriction can play a vital role in bolstering your immune system. Lower calorie intake can lead to a more efficient and robust immune system, making you better equipped to fight off infections and diseases.

By promoting cellular repair and maintenance processes like autophagy, calorie restriction helps keep the cells of your immune system in top condition. Calorie restriction can lead to improved sleep quality, an essential component of overall health. Many people find that they sleep more soundly when they reduce their calorie intake.

A balanced diet with controlled calories can help regulate your circadian rhythm, leading to more consistent sleep patterns. Lower calorie consumption, particularly by reducing late-night eating , can reduce sleep disturbances, leading to a more restful night.

Better sleep quality means waking up feeling more refreshed and energized. Implementing calorie restriction in your diet is a journey that requires careful planning and consideration.

Understanding your caloric needs is the first step in implementing calorie restriction effectively:. Choosing quality over quantity is crucial when implementing calorie restriction.

Focus on foods that are high in nutrients but low in calories. Fruits, vegetables, lean proteins, and whole grains are excellent choices. Steer clear of foods with empty calories — those high in sugar and unhealthy fats but low in nutritional value, like fast food and sugary snacks.

Ensure your meals have a good balance of protein, carbohydrates, and healthy fats to keep you nourished and satisfied [ 7 ].

Pay attention to portion sizes, even when eating healthy foods. The goal is to nourish your body with the right kind of food, not just reduce calorie intake.

A well-balanced diet will support your health goals more effectively than simply cutting calories without considering the nutritional value of your food. Meal planning and preparation are key components of successfully implementing calorie restriction.

Allocate some time each week to plan your meals. This helps ensure a balanced diet and prevents impulsive, unhealthy eating. Prepare and cook your meals in advance.

This can be a huge time-saver and helps you stick to your calorie goals. When preparing meals, be mindful of portion sizes to avoid unintentional overeating. Include a variety of foods in your plan to ensure you get a range of nutrients and to keep meals interesting.

Prepare healthy snacks for those moments when you need a quick bite. This helps avoid reaching for high-calorie, low-nutrient options.

With careful planning and preparation, you can make calorie restriction a more manageable and enjoyable part of your routine.

Mindful eating is a crucial aspect of calorie restriction, enhancing your relationship with food. Take time to chew your food thoroughly and eat slowly.

This aids digestion and gives your body time to recognize fullness. Pay attention to the flavors, textures, and aromas of your food.

What Are the Different Forms of Calorie Restriction and Fasting? Media Contact Fred Mamoun: fred. Research reviews in and concluded that the two types of diet have similar effects on weight loss. Weight management is a central benefit of calorie restriction. What's the Evidence from Human Studies of Fasting? With time and patience, these initial adjustments pave the way to more significant, long-term benefits. By Alina Petre, MS, RD NL. You'll then slowly add more calories to your diet to help maintain the weight you've lost.
The CALERIE study

Participants in the study were not followed up with after the two-year intervention. A separate study, also funded by the agency, is planning to look at the effects of a calorie-restricted diet after 10 years, he added.

Still, Hadley said, the new study reinforces findings from previous research that some calorie restriction can promote health benefits, including living longer and healthier lives.

Researchers still don't know exactly why cutting calories appears to slow the aging process, though there is evidence that calorie restriction prompts changes at the cellular level, Belsky said.

There are resource stresses in the environment. We need to make sure that we are using all of the resources available to us most efficiently.

Pankaj Kapahi, a researcher at the Buck Institute for Research on Aging, said that along with calorie restriction, exercise and eating a balanced diet are also important factors to consider for aging. He was not involved in the research. Kapahi added that the study's findings do not mean people should starve themselves, saying that could lead to malnutrition and poor mental health.

Valter Longo, a biochemist and director of the Longevity Institute at the University of Southern California, said that limiting calories for extended periods of time can be harmful.

Studies in animals, for example, have shown that long-term calorie restriction was found to be associated with a risk of reduced muscle strength, slower metabolism and an impaired immune system, said Longo, who was not involved in the study. Hadley cautioned against overinterpreting the results, saying calorie restriction may not be for everyone, including those with multiple underlying conditions.

He advised speaking with a doctor before undergoing a calorie-restricted diet. Berkeley Lovelace Jr. The overall aim of the clinical trial was to see if calorie restriction is as beneficial for humans as it is for lab animals, said Vishwa Deep Dixit , the Waldemar Von Zedtwitz Professor of Pathology, Immunobiology, and Comparative Medicine, and senior author of the study.

And if it is, he said, researchers wanted to better understand what calorie restriction does to the body specifically that leads to improved health. Since previous research has shown that calorie restriction in mice can increase infections, Dixit also wanted to determine how calorie restriction might be linked to inflammation and the immune response.

Dixit and his team started by analyzing the thymus, a gland that sits above the heart and produces T cells, a type of white blood cell and an essential part of the immune system. The thymus ages at a faster rate than other organs. And as it ages, the thymus produces fewer T cells. For the study, the research team used magnetic resonance imaging MRI to determine if there were functional differences between the thymus glands of those who were restricting calories and those who were not.

They found that the thymus glands in participants with limited calorie intake had less fat and greater functional volume after two years of calorie restriction, meaning they were producing more T cells than they were at the start of the study.

With such a dramatic effect on the thymus, Dixit and his colleagues expected to also find effects on the immune cells that the thymus was producing, changes that might underlie the overall benefits of calorie restriction.

But when they sequenced the genes in those cells, they found there were no changes in gene expression after two years of calorie restriction.

Dixit and his team had studied adipose tissue, or body fat, of participants undergoing calorie restriction at three time points: at the beginning of the study, after one year, and after two.

Body fat is very important, Dixit said, because it hosts a robust immune system. Nutritional interventions modulating aging and age-associated diseases.

Caloric needs for a balanced lifestylecaloric restriction benefits -

There are no food restrictions or strict guidelines, just the number of calories you can eat on certain days or weeks. Research suggests the benefits of calorie cycling include greater weight loss , improved ability to stick to a diet, less hunger, and a reduction in the negative hormonal and metabolic adaptations of a normal weight loss diet.

Although this is a fairly new approach, hunter-gatherers likely had a similar eating pattern centuries ago because food was not available in the same amounts every day.

There were periods when food was scarce and other times when it was abundant, depending on the time of year and degree of hunting success. Calorie cycling is an eating pattern in which you cycle your calorie intake from day to day or week to week. To understand why calorie cycling may be beneficial, you need to understand why conventional diets can be unsuccessful in the long term.

A review of weight loss studies found that most people regained more than half the weight they had lost within 2 years. Studies show that most dieters regain most of the weight they initially lose and often end up weighing even more than before.

Many studies highlight the metabolic adaptations and psychological factors that cause diets to fail in the long term. The adaptations caused by dieting suggest that your body senses it as a potentially dangerous state.

Centuries ago, a low calorie period of time could equate to starvation or illness. To survive, the brain would send various signals to the body to preserve energy. It does this via numerous biological changes, which are collectively called metabolic adaptations.

These negative adaptations include:. These adaptations are the exact opposite of what you need for successful long-term weight loss.

These changes could occur to some degree with calorie cycling as well. A typical low calorie diet will negatively affect hunger, hormones, and metabolism. These changes make it very hard to maintain weight loss in the long term.

Your body does everything in its power to slow down weight loss, conserve energy, and even regain the weight after dieting. Changes to weight-regulating hormones play a key role in this.

Like a seesaw, leptin decreases hunger and ghrelin increases it. The researchers noted that this was consistent with the belief that ghrelin plays a part in long-term regulation of body weight. This is one potential benefit of calorie cycling, as higher-calorie periods may reduce ghrelin and increase leptin.

Dieting can cause an increase in the hunger hormone ghrelin and a decrease in the fullness hormone leptin. Calorie cycling may help by reducing these negative hormonal adaptations.

Some studies have found sharp declines in the number of calories people burn per day when cutting calories. Four weeks after treatment, some significant weight loss and fat loss had started, and both continued up to a 1-month follow-up.

As shown in the graph below, a study found almost a calorie reduction in calories burned at rest after 8 weeks on a weight loss diet.

Another study found that a 3-week low calorie diet decreased metabolism by more than calories. However, when participants switched to a higher-calorie diet in the fourth week, their metabolism increased to above starting levels.

A 7-week study of resistance-trained participants found that during an energy-restricted diet, a consecutive 2-day carbohydrate refeed more effectively prevented the loss of fat-free body mass than continuous energy restriction.

A review found that intermittent energy restriction diets had more effect on weight loss than continuous energy restriction diets, but the researchers noted that longer trials are necessary to confirm this. However, other research has found little difference between the benefits of intermittent and continuous energy restriction diets.

Research reviews in and concluded that the two types of diet have similar effects on weight loss. Overall, according to the National Institute on Aging , more research is needed to fully understand the long-term health benefits of calorie cycling. Research suggests that an intermittent energy restriction diet with periodic high calorie days may increase your metabolism and hormone levels more successfully than a continuous energy diet, but further studies are needed.

After a few weeks on a low calorie diet, you may notice physical effects such as a decrease in energy, workout performance, sleep, or sex drive or a fat loss plateau.

This is when you may want to add a higher-calorie period. Some people enjoy having higher-calorie days every week — for example, 5 low calorie days and 2 high calorie days. Others like to get into a set routine and diet for a strict 2—4 weeks before adding slightly longer 5- to 7-day high calorie periods.

Since exercise plays an important role in health and weight loss, it makes sense to tailor your calories to your activity level. Therefore, it makes sense to schedule your longest and most intense exercise sessions on high calorie days. On the other hand, save the lighter exercise sessions or rest days for your low calorie days.

If you exercise only for health and weight loss, you can keep it simple and follow the example protocols listed above. No, they're not. Calorie restriction means reducing average daily caloric intake below what is typical or habitual, without malnutrition or deprivation of essential nutrients.

In a fasting diet, a person does not eat at all or severely limits intake during certain times of the day, week, or month. A practical effect of a fasting diet may be fewer calories because there is less time for regular eating.

These eating patterns are being studied as possible ways to maintain good health and live longer. They are not temporary weight-loss plans.

Interest in their potential health and aging benefits stems from decades of research with a variety of animals, including worms, crabs, snails, fruit flies, and rodents. In many experiments, calorie-restricted feeding delayed the onset of age-related disorders and, in some studies, extended lifespan.

Given these results in animals, researchers are studying if and how calorie restriction or a fasting diet affects health and lifespan in people.

Many studies have shown that obese and overweight people who lose weight by dieting can improve their health. But scientists still have much to learn about how calorie restriction and fasting affect people who are not overweight, including older adults.

They also don't know whether these eating patterns are safe or even doable in the long run. In short, there's not enough evidence to recommend any such eating regimen to the public. Calorie restriction is a consistent pattern of reducing average daily caloric intake, while fasting regimens primarily focus on the frequency of eating.

The fasting diet may or may not involve a restriction in the intake of calories during non-fasting times. There are a variety of fasting diets, sometimes called "intermittent fasting.

More animal research has been done on calorie restriction than on fasting. In some experiments, calorie restriction is also a form of fasting because the lab animals consume all their daily allotted food within hours and go many more hours without any food.

In these studies, when rodents and other animals were given 10 percent to 40 percent fewer calories than usual but provided with all necessary nutrients, many showed extension of lifespan and reduced rates of several diseases, especially cancers.

But, some studies did not show this benefit, and in some mouse strains, calorie restriction shortened lifespan rather than extending it. In the worm C. elegans , a fasting diet increased lifespan by 40 percent.

A study with fruit flies found that calorie restriction—but not intermittent fasting—was associated with living longer. One study of male mice found that lifelong alternate-day fasting increased longevity, mainly by delaying cancer occurrence rather than slowing other aging processes.

Two National Institute on Aging NIA -supported studies in rhesus monkeys sought to find out whether the benefits of calorie restriction are seen in longer-lived species.

In both studies, the monkeys were kept on a calorie-restriction diet 30 percent fewer calories than for monkeys in the control groups for more than 20 years. Although there were differences between the two studies—including monkey breed and type of food—both provided evidence that calorie restriction reduced the incidence of age-related conditions, such as cancer, heart disease, and diabetes.

One study found an extension of lifespan, while the other did not. Many of the monkeys are still alive, so the full impact of calorie restriction on their maximum lifespan has yet to be determined.

Some study results suggest that calorie restriction may have health benefits for humans, but more research is needed before we understand its long-term effects. There are no data in humans on the relationship between calorie restriction and longevity. Some people have voluntarily practiced extreme degrees of calorie restriction over many years in the belief that it will extend lifespan or preserve health.

Studies on these individuals have found markedly low levels of risk factors for cardiovascular disease and diabetes. The studies have also found many other physiologic effects whose long-term benefits and risks are uncertain, as well as reductions in sexual interest and the ability to maintain body temperature in cold environments.

These people generally consume a variety of nutritional supplements, which limits knowing which effects are due to calorie restriction versus other factors. To conduct a more rigorous study of calorie restriction in humans, NIA supported a pioneering clinical trial called Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy CALERIE.

In CALERIE, young and middle-aged, normal-weight or moderately overweight adults were randomly divided into two groups. People in the experimental group were told to follow a calorie-restriction diet for 2 years, while those in the control group followed their usual diet.

The study was designed to have participants in the experimental group eat 25 percent fewer calories per day than they had regularly consumed before the study. Although they did not meet this target, they reduced their daily caloric intake by 12 percent and maintained, on average, a 10 percent loss in body weight over 2 years.

A follow-up study 2 years after the intervention ended found that participants had sustained much of this weight loss. It's important to note that calorie-restriction regimens are not starvation diets. The weight loss achieved with calorie restriction in the CALERIE trial resulted in body weights within the normal or overweight range.

Compared to participants in the control group, those in the calorie-restriction group had reduced risk factors lower blood pressure and lower cholesterol for age-related diseases such as diabetes , heart disease , and stroke.

They also showed decreases in some inflammatory factors and thyroid hormones. There is some evidence that lower levels of these measures are associated with longer lifespan and diminished risk for age-related diseases.

Moreover, in the calorie-restricted individuals, no adverse effects and some favorable ones were found on quality of life, mood, sexual function , and sleep. The calorie-restriction intervention did cause slight declines in bone density, lean body mass, and aerobic capacity the ability of the body to use oxygen during exercise.

However, these declines were generally no more than expected based on participants' weight loss. Other short-term studies have found that combining physical activity with calorie restriction protects against losses of bone, muscle mass, and aerobic capacity.
