Raspberry ketones for enhanced athletic performance

Raspberry ketones for enhanced athletic performance

Aathletic as an aside, dor did, we did another study Gut health maintenance it enhnaced just at one hour on a treadmill, followed by a 10k time trial. Though raspberry ketones are considered safe and cause few side effects, they can occasionally cause certain side effects such as rapid heartbeat, low blood sugar, increased blood pressure, and jitteriness. Brendan Egan Now look at the great points. Like esters being used in the pro peloton?

But, no human studies support these claims. More than a third of Americans are overweight — and another third are obese 1. However, many products are advertised to aid weight loss.

Certain herbs, shakes and pills are supposed to help you burn fat or reduce your appetite. Raspberry ketones are claimed to cause the fat within cells to be broken down more effectively, helping your body burn fat faster. They are also claimed to increase levels of adiponectin, a hormone that helps to regulate metabolism.

This substance is also found in small amounts in other fruits and berries , such as blackberries, cranberries and kiwis.

It has a long history of use in cosmetics and has been added to soft drinks, ice cream and other processed foods as a flavoring. As such, most people already eat small amounts of raspberry ketones — either from fruit or as a flavoring 3.

Extracting raspberry ketones from raspberries is extraordinarily expensive because you need 90 pounds 41 kg of raspberries to get a single dose. In fact, 2. The raspberry ketones you find in supplements are synthetically manufactured and are not natural 4 , 5 , 6. However, raspberry ketones have absolutely nothing to do with low-carb diets and will not have the same effects on your body.

Raspberry ketone is the compound that gives raspberries their strong aroma and flavor. A synthetic version of it is used in cosmetics, processed foods and weight loss supplements. The molecular structure of ketones is very similar to two other molecules, capsaicin — found in chili pepper — and the stimulant synephrine.

Studies indicate that these molecules can boost metabolism. Therefore, researchers speculated that raspberry ketones could have the same effect 7 , 8. In test-tube studies of fat cells in mice, raspberry ketones 9 :. Adiponectin is released by fat cells and may play a role in regulating metabolism and blood sugar levels.

People with normal weight have much higher levels of adiponectin than those who are overweight. Levels of this hormone increase when people lose weight 10 , Studies demonstrate that people with low adiponectin levels are at a higher risk of obesity, type 2 diabetes, fatty liver disease and even heart disease 12 , Therefore, it seems that raising adiponectin levels could help people lose weight and lower the risk of many diseases.

However, even if raspberry ketones raise adiponectin in isolated fat cells from mice, this does not mean that the same effect will occur in a living organism. Keep in mind that there are natural ways to increase adiponectin that do not involve raspberry ketones.

Drinking coffee is also linked to higher levels 14 , 15 , Raspberry ketones have a similar molecular structure as two known fat-burning compounds. While they show potential in test-tube studies, these results do not necessarily apply to humans.

In one study, raspberry ketones were given to some mice fed a fattening diet In another study in 40 rats, raspberry ketones increased adiponectin levels and protected against fatty liver disease You would have to take times the recommended amount in order to reach the equivalent dose.

A dosage this severe is never advisable. Although some studies in rodents show that raspberry ketones can protect against weight gain and fatty liver disease, these studies used massive dosages — much higher than you would get with supplements.

The only human study that comes close used a combination of substances, including caffeine, raspberry ketones, garlic , capsaicin, ginger and synephrine In this eight-week study, people cut calories and exercised. Those who took the supplement lost 7.

However, the raspberry ketones may have had nothing to do with the observed weight loss. The caffeine or any of the other ingredients could be responsible.

Comprehensive studies in humans are needed before the effects of raspberry ketones on weight can be fully assessed. There is no evidence that raspberry ketone supplements can cause weight loss in humans. More research is needed. When administered topically as part of a cream, raspberry ketones appear to increase hair growth in people with hair loss.

It may also improve skin elasticity in healthy women However, this study was small and had a number of flaws. More studies need to confirm these effects before any claims can be made One small study proposes that raspberry ketones, administered topically, can increase hair growth and improve skin elasticity.

While there are anecdotal reports of jitteriness, rapid heartbeat and increased blood pressure, there are no studies to support this. Without human studies on raspberry ketones, there is no good data on side effects or a science-backed recommended dosage.

While they seem to work in test animals fed extreme doses, this has no relevance to the doses commonly recommended in humans.

The diet was developed in the s to treat epileptic children.

These fat-burning adaptations can take weeks, months, or even years. By consuming exogenous ketones, athletes give themselves an additional source of fuel that they can burn first, thus preserving glycogen.

That is, of course, if they can get past the taste. I liken the flavor to a mixture of raspberry-flavored vodka, cough syrup, and nail polish remover, others have described it as a mix of rubbing alcohol and toilet cleaner with a hint of fruit.

With less lactate, your muscles feel less tired. As a result, ketone esters may contribute to lower perceived exertion and a feeling of steadier energy throughout a run. In addition to enhancing performance, there is evidence suggesting that ketones promote better recovery. In a review article published in the Journal of Physiology last year, Egan and colleagues evaluated the existing research on how ketones affect the body during and after training.

They concluded that post-exercise ketosis, whether achieved through diet or supplementation, is likely to help with both rebuilding glycogen and resynthesizing muscle—the two main goals of recovery. However, in order to access this ketone-driven benefit, runners trying to induce ketosis through diet would need to avoid eating carbs—which is typically what they should eat immediately after a workout during the time window when the body can store glycogen away the fastest.

Ketone esters appear to solve this problem. Despite the buzz, research and theory behind ketone esters still leave many questions unanswered. Can they help recreational athletes, or are benefits limited to elites?

Thus far, the only scientific studies that have found a performance benefit in humans have been conducted on the latter—people at the very top of the performance spectrum.

And on small sample sizes just eight cyclists in the study mentioned above , which isn't an accurate representation of the total population. Still, the anecdotal evidence is enough to at least spark interest. Bronco Billy , an ultrarunner and online endurance coach.

No major lows in energy. Definitely worked. My long-run trial with HVMN Ketone was similar: My energy level was extremely consistent, and I never felt hungry, despite having skipped breakfast. Initial research and early anecdotal evidence seem promising for ketone esters. That said, the research is still in its infancy.

And the most important aspect of using a ketone supplement is its effect on blood ketone levels, which need to be monitored. But for me personally, if I could run a whole marathon feeling as energized as I did during that long run? When not writing or reading, she can be found running, baking, or petting her cat, Tabouli.

The area of increasing fat utilisation is nothing new as we have had the high fat diets, low carb diets, use of Medium-chain triglycerides MCTs and more recently 3-beta-hydroxybutyrate and acetoacetate.

There may be benefits in glycogen sparing but if current nutritional strategies carb intake address this - then we need to see data that ketones outstrip carbohydrates as a recovery aid. Over the distance and intensities of the Tour de France I am not a believer at this time based on the available data that supplemental ketones are more effective than carbs for recovery and or performance.
