But another argument against keto for athletes has to do with glycogen stored glucose in muscle. If glycogen stores are low during exercise, this could compromise energy availability and limit performance. Not something that any athlete wants. However, this may be more of a concern for athletes involved in endurance activities where glycogen depletion becomes an issue. Athletes in sports involving heavy lifts or bodybuilding might not experience negative effects from low glycogen.
In fact, keto-adapted athletes who were compared to athletes consuming around grams of carbohydrates per day actually had similar levels of stored muscle glycogen. Volek Something happens to keto-adapted athletes that allow them to maintain glycogen levels at a high level. But what? Maintenance of glucose and glycogen levels in the body in the absence of carbohydrate consumption can occur through a process known as gluconeogenesis , or GNG for short.
GNG is a process that our body uses to create glucose out of non-carbohydrate sources—mainly amino acids and glycerol from fatty acids. But we are primarily interested in muscle growth for this article. While the foundation is sound, what does the evidence actually say about building muscle on a ketogenic diet? The theory goes that, since protein is essential for growing large muscles, restricting your intake might lead to a significant loss of muscle tissue or an inability to get bigger.
However, some research has been done that points to a net benefit of the keto diet on markers of muscle growth and maintenance. Building muscle is great, but another goal of many strength-based athletes is to optimize body composition. A low-carb high-fat diet can do this. Research has shown that athletes who adopt a keto diet experience greater body fat loss than a group of high-carb dieters.
Being keto adapted ultimately leads to a greater ability to utilize fat from food and body storage areas. As long as lean mass is maintained which most studies show is the case , increased fat burning capacity will result in improved body composition—less fat and more lean muscle.
However, research shows exactly the opposite—that the ketogenic diet actually prevents muscle from being broken down. When an equal number of calories are consumed on diets containing the same amount of protein but differing levels of carbs, the lower-carb diets actually maintain lean muscle mass to the greatest extent.
Ketosis might actually improve our ability to utilize proteins. This could be due to the fact that the body no longer needs to breakdown protein for gluconeogenesis —instead utilizing ketones, sparing the protein we have.
Studies support this. During ketosis and infusion of ketone bodies, it is shown that the utilization of BCAAs for energy is reduced, leading to enhanced protein synthesis and muscle maintenance. Not only do ketones spare protein for muscle maintenance, but they actually can significantly increase muscle protein synthesis. Athletes who ingested a ketone supplement made of a BHB monoester had increased activity of mTOR, leading to a doubling of protein synthesis.
Ketosis seems to have some profound effects of various markers of protein synthesis within the muscle. But how do athletes on a ketogenic diet respond to training. Do the studies show that muscle mass can improve? As the ketogenic diet has risen in popularity with athletes, more researchers are becoming interested in testing the efficacy of this diet for performance. In one study, a low-carb diet was compared to a traditional western diet during a week resistance training intervention in healthy young males.
After 10 weeks, the group on the low-carb diet diet group gained 2. Wilson However, the keto diet actually led to a greater increase in testosterone throughout the study.
When some people start this diet, they may experience the keto flu — a collection of symptoms, such as fatigue, nausea, irritability, and insomnia, that occur as your body adapts to its new regimen.
Beware of hidden carbs. Test your ketone levels regularly. Get plenty of sleep. Proper sleep is very important for muscle gain and exercise performance 37 , To optimize muscle growth on the keto diet, make sure you have a solid nutrition plan and get plenty of sleep.
Also, make sure to monitor your carb intake and ketone levels to ensure you stay in ketosis. Though it involves carefully watching your protein, carb, and fat intake, the keto diet may be as effective as traditional higher carb diets for building muscle.
Simply following the above guidelines can help you plan an effective keto strategy for building muscle. Protein powders are a convenient and tasty way to increase your intake of this important nutrient, even when you're watching your carb intake. The ketogenic diet keto is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. This is a detailed beginner's…. A ketogenic diet is a very low-carb diet with numerous health benefits.
Here are 15 healthy and nutritious foods you can eat on this diet. Ketogenic diets have many powerful health benefits, but some people have trouble getting into ketosis.
Here are 7 tips for how to get into ketosis. To get optimal results on a low-carb diet, just cutting back on carbs isn't enough. There are other aspects of the diet that are also important. Research has shown that low-carb, high-fat diets such as the keto diet can promote fat loss and improve certain health conditions.
This article offers…. Staying in the metabolic state of ketosis on a low-carb keto diet requires reducing sugar consumption. Combining resistance training with a ketogenic diet had no beneficial or adverse effects on the preservation of muscle mass during weight loss compared to the same training program paired with a conventional diet.
After a period of intelligent experimentation, they seem to do better with fewer carbs in their diet. You may be one of those people. Most low-carb diets get a lot of things right—the focus is usually on eating simple, wholesome, nutrient-dense foods that tend to fill you up on fewer calories. Lifting weights triggers an increase in muscle protein synthesis, which is the key driving force behind muscle growth.
Carbohydrate comes in handy because it helps you put in the work that stimulates muscle growth, not because it makes a direct contribution to growth per se. They feel tired and mentally fuzzy. If you do a lot of intense exercise, the quality of your workouts may decline. Many people do just fine with a moderate intake of carbs, cutting out the sugary snacks and replacing some of the starchy carbs with fruit and vegetables.
If you want to get rid of your gut while building some muscle at the same time, a ketogenic diet is a viable option. Indeed, a study shows that a group of resistance-trained men failed to gain any muscle at all after two months of lifting weights on a ketogenic diet.
Christian Finn is a UK-based personal trainer with a masters in exercise science. Weeks I recommend you consume your macros in the following ratios remembering to lower out fat intake again.
Now I know what you are thinking! By now you are probably asking yourself what your daily caloric intake should be in order to build muscle and lose fat. I realise I have given most of the macro ratio numbers in percentages in this post.
Those percentages do of course relate to our daily caloric intake. I will be totally honest with you here, and then direct you to another one of my articles where you can learn more about your Total Daily Energy Expenditure TDEE and how to work out what your daily caloric intake should be.
Controversial I know! Now in the beginning it would certainly be helpful for you to track your ratios using any popular tracking app on your phone. However, I eat when I am hungry and stop when I am full. I make sure my ratios and as close as possible and I train hard in the gym. I find that this works well for me. Over tracking your numbers can become very taxing mentally and you want to try to avoid become OCD about the numbers. Of course, muscle growth is also very much dependent on you partaking in an effective exercise regime which focuses on breaking down the muscle fibres in your body.
This type of strength training causes the muscle tissue to grow in size as the fibres repair themselves. It is important to focus on training the large muscle groups such as chest, legs and shoulders for example.
Also, you will get the best results by making sure that you train to total failure on each set. This means that at the end of each set, you are not able to physically perform even just one more repetition of that particular exercise. Utilised in the correct way and along with effective and efficient resistance training, the keto diet can absolutely accelerate your muscle growth while providing you with many other health benefits as well.
At the end of the day it all depends on your own goals and aspirations. Take the information in this article and use it as a guide. Strive to do your best everyday. No one can ask any more of you.
