But the typical diet contains only a fraction of the amount of DHA and EPA that are needed for optimal health. The essential fats are best known for improving heart health, in part by increasing the elasticity of blood vessels. A lesser known benefit of the essential fats is that they increase insulin sensitivity.

When higher levels of essential fats are consumed, more essential fats are incorporated into cell membranes. Cell membranes containing more essential fats are more permeable, enabling nutrients and other materials to enter and exit the cell more easily.

Increased consumption of essential fats improves insulin sensitivity by making insulin receptors in the cell membrane more responsive and by allowing the nutrients that insulin transports to enter the cell more easily.

When a diet providing optimal amounts of essential fats is combined with other healthy eating habits and regular exercise, insulin sensitivity in the muscle cells is maximized. This helps muscles grow and eat more body fat.

Unfortunately, it is very difficult to obtain optimal amounts of DHA and EPA from regular foods every day. For this reason we recommend that you take a daily fish oil supplement.

Simple carbohydrates are sugars and starches that have relatively small molecular sizes. Most of them are digested and absorbed into the bloodstream as glucose quickly compared to complex carbohydrates.

The fast absorption of simple carbohydrates can be a good thing or a bad thing, depending on when you consume them. If large amounts of quickly absorbed carbohydrates are consumed when they body does not need a lot of energy, the resulting spike in blood glucose will trigger the pancreas to release a large amount of insulin, which will transport much of the excess glucose to the liver for conversion to fat.

But if simple carbohydrates are consumed when the body needs quick energy, this does not occur. The best time to consume simple carbs is within an hour after exercise, when the muscles are insulin sensitive and need glucose to replenish depleted fuel stores.

At this special time, the release of insulin caused by the rapid influx of glucose into the blood stream will create a nutrient stampede straight to the muscles.

If you consume protein along with simple carbs at this time, the amino acid building blocks of these proteins will get caught up in the stampede, resulting in rapid muscle protein synthesis. Research has shown that the muscles build new proteins much faster after exercise when protein is consumed along with simple carbs than when protein is consumed alone, or with slower, complex carbs.

There are four key nutrients that inhibit and reduce fat storage: protein, complex carbohydrates, fiber and calcium. Protein does double duty in the energy partitioning game: it promotes muscle growth and reduces fat storage.

Due to its nitrogen content, protein is not as easy for the body to convert into stored fat as carbohydrate or fat itself. The body prefers to use protein to support the muscles and other protein-containing tissues, especially when there is a high demand for protein in the body, which is the case when you exercise regularly or eat fewer calories than your body burns in a day.

Studies have shown that dieters lose more fat and retain more muscle on a high-protein low-calorie diet than they do on a moderate-protein low-calorie diet. Protein is also the most satiating macronutrient, so when you include enough protein in your meals and snacks you feel full faster, stay full longer, and consequently eat less throughout the day.

And when you eat less, you store less fat. Research has found that men and women voluntarily eat fewer total calories each day on a high-protein diet than they do on a moderate-protein diet.

Complex carbohydrates are starches with a large chemical structure. All carbohydrates, simple and complex, are broken down to the simplest carbohydrate of all, glucose, through the digestive process.

But complex carbohydrates are typically digested and absorbed into the liver and bloodstream as glucose more slowly than simple carbohydrates although there are notable exceptions. The faster a carbohydrate consumed in food is absorbed as glucose, the more likely it is to be converted to, and stored as, fat.

Complex carbohydrates are therefore less likely to add to your body fat stores. Research has shown that men and women who get most of their dietary carbohydrate from complex carbs found mainly in vegetables and whole grains are leaner than those who get most of their carbohydrates from simple carbs found mainly in refined grains and sugary foods.

A recent study involving mice whose diets can be controlled much more thoroughly than those of human subjects makes the point very powerfully.

For six months, one group of mice was fed a diet based on complex carbs, while the other was fed a diet based on simple carbs.

At the end of six months, both groups of mice weighed the same, but those on the diet of simple carbs had twice as much body fat! Dietary fiber helps you win the game of energy partitioning by literally getting in the way of fat storage. Fiber is an indigestible component of plant foods.

There are actually two major types of fiber: soluble fiber, which is partially digestible, and insoluble fiber, which is totally indigestible.

When you consume fiber, it takes up space in your stomach, providing a feeling of fullness that encourages you to stop eating, but unlike other nutrients that create fullness specifically, protein, fat, and carbohydrate , fiber does so without contributing any calories to your body.

It passes straight through your digestible system and is eliminated without ever becoming part of your body. In addition to not being absorbed into your body, fiber also slows down the absorption of other nutrients.

This effect also reduces fat storage, because food calories are most likely to be stored as fat when they are absorbed quickly. The best sources of fiber are fruits and vegetables. Also called energy partitioning, does this concept hold a scientific basis?

Allow this guide to answer the most burning questions including, what is nutrient partitioning and how is it achieved? A concept first introduced into the bodybuilding world by John Parillo, nutrient partitioning refers to how different nutrients are fated after being ingested.

He aimed to explain why certain foods preferentially build muscle while others promote fat accumulation and storage. It relies on the premise that healthy versus unhealthy carbohydrates, fat, and protein to some extent affect body composition differently.

When simple carbohydrates like processed and packaged food are consumed, the body will secrete insulin and either burn it as fuel or convert it into fat for storage. When fat is eaten, the body can use it as fuel via a slower mechanism than carbohydrates or store it in adipose tissue as well.

Conversely, when protein is consumed, the body will utilize it to build, grow, and repair new muscle and tissue or store it as fat if there is an abundance. However, the degree to which these processes happen depends on genetics, hormone balance and influences, meal timing, and most importantly, according to the nutrient partitioning concept, the quality of the macros.

Nonetheless, the three main purposes of nutrient partitioning can be summarized as:. Partitioning nutrients to the correct location is best achieved through meal timing around exercise and via consuming quality, nutrient-dense foods that promote muscle growth and reduce fat storage.

Yet, the science of nutrient partitioning relies on manipulating hormones to a large extent. Exercise elicits chemical changes that affect the brain and muscle and fat tissue in important ways. First of all, exercise encourages nutrient partitioning by making muscle tissue more insulin sensitive compared to fat tissue.

Muscles are composed of protein and also store carbohydrates in the form of glucose, and the body partially breaks down this protein and utilizes the glucose as fuel during exercise. Although insulin normally facilitates fat storage, exercise causes insulin to facilitate the storage of protein and carbohydrates back into muscles.

This complex mechanism makes muscle tissue more insulin sensitive than fat tissue, so the muscles respond more to a less amount of insulin. Ultimately, this allows them to uptake the nutrients and calories from protein and carbs more efficiently and discourages fat storage.

Additionally, intense exercise causes the secretion of a special signaling molecule called interleukin-6 IL This secretion not only encourages the body to use stored fat molecules for fuel during exercise, but increased levels of this molecule in the brain after exercise lead the brain to direct calories consumed during the post-workout period to muscles and away from adipose tissue.

The above metabolic effects of exercise last for hours after completion of the workout and lead to long-term changes that enhance these consequences further. Thus, consistent exercise adequately partitions nutrients by encouraging a metabolic state where muscles essentially hog calories and fat tissue sacrifices its stored energy and is denied new calories.

Although exercise is the easiest way to partition nutrients, combining it with a tailored nutrition plan will only enhance results. Because certain nutrients tend to promote skeletal muscle tissue growth and others inhibit or reduce body fat storage, one can further maximize the effects by eating them at the most appropriate times.

Generally speaking, protein, essential fatty acids, and simple carbohydrates spur muscle growth while protein, complex carbs, fiber, and calcium reduce fat storage.

Protein is the main structural component of muscle tissue and accounts for twenty percent of muscle mass. Muscle tissue can only grow with sufficient protein consumption, which is the only macronutrient that contains nitrogen. Furthermore, while essential fatty acids DHA and EPA are frequently associated with brain and heart health, they also help increase insulin sensitivity without initiating insulin secretion.

Double win. When sufficient and even high levels of essential fats are consumed, more of them are incorporated into cell membranes, making them more permeable and enabling nutrients to enter and exit more easily.

Moving along to simple carbohydrates, it is generally recommended to limit simple carbohydrates in the diet because of the resulting spike in insulin and subsequent blood sugar crash. Plus, if the simple carbohydrates are not needed for energy, they will be transported to the liver for conversion to fat.

However, when the body needs quick energy, like after exercise to replenish muscle tissue energy stores, this process does not occur. Instead, when simple carbs are consumed within an hour after exercise when muscles are most insulin sensitive, the rapid release of insulin will shuttle the energy straight to the muscles.

Because of its nitrogen content, protein is not easy for the body to convert into stored fat. Instead, the body prefers to use protein to support muscles and other tissues that contain high amounts of protein.

Nutrient partitioning can be defined as the process by which the organism selects fuels for storage including protein synthesis or oxidation. Understanding the regulation of energy balance and nutrient partitioning can potentially facilitate the treatment of obesity.

The latter suggests that total food intake increases to meet carbohydrate needs. According to this theory, food intake is regulated, at least in part, to assure an adequate amount of carbohydrate.

Consumption of a high-fat diet would require the intake of excess fat in order to satisfy carbohydrate needs and therefore lead to obesity under this scenario. For example, if fat were preferentially shunted toward storage, more carbohydrate would be required to meet oxidative needs, thereby preventing suffcient repletion of glycogen stores.

This process is proposed to generate signals that stimulate appetite. Other examples where nutrient partitioning relates to obesity and body fat content include the stimulation of lean tissue synthesis at the expense of fat calories by androgens and growth hormone, and presumably the reverse of this process by deficiencies of these hormones.

Certain nutrients tend to promote muscle tissue growth, while others tend to inhibit or reduce body fat storage, and some even do both. By combining regular exercise with a diet that is based on these nutrients, you will maximize improvements in your body composition.

We could write a whole book on the effects of various nutrients on muscle and fat tissue, but for our purposes it will suffice to highlight a few. There are three key nutrients that promote muscle growth: protein, essential fats, and simple carbohydrates when consumed at the right times.

Protein is the main structural component of muscle tissue. It accounts for roughly 20 percent of muscle mass; the rest is mainly water. Muscles grow when protein is added to them. When protein is added, water follows automatically.

Protein is the only macronutrient that contains nitrogen. Carbohydrate and fat do not. Therefore, eating protein is the only way to make more protein available to the muscles so they can grow.

Ten years ago the average person did not know much about essential fats. These days, essential fats are all over the news and commercial advertising. The essential fats DHA and EPA cannot be synthesized from other fats inside the body, so they must be obtained in the diet. But the typical diet contains only a fraction of the amount of DHA and EPA that are needed for optimal health.

The essential fats are best known for improving heart health, in part by increasing the elasticity of blood vessels. A lesser known benefit of the essential fats is that they increase insulin sensitivity.
