To eat, or not to eat? That is the question.
If you were to ask a group of people if working out on an empty stomach is okay, you would hear half say yes, and the other half say no.
With all of the bro science and internet gurus out there, a lot of opinions are thrown around with little research to back it.
Science suggests that your metabolism and digestive system isn’t as frail as a flower, as some may believe.
Your Body Optimizes Hormones
Hugh Jackman practiced intermittent fasting to gain muscle for his latest Wolverine movie.
If that doesn’t prove that training on an empty stomach is okay, lets dive into some science…
When we eat something, our body releases insulin to help us absorb nutrients from our food. After that, insulin shuttles the sugars out of the blood stream and sends them to your liver, muscles, and fat cells to be used as energy later on.
Eating too much or too many times in a certain period of time consistently makes our bodies more resistant to insulin and its effects. Poor insulin sensitivity makes it hard to lose body fat and has been shown to increase your risk of heart disease or cancer.
If you were to cut down alcohol consumption and then drink after a short period of not drinking, the effects of alcohol are more prevalent. The same goes with insulin – fasting allows less insulin to be released, improving the effectiveness of insulin.
Another bonus of fasting is that it helps promote muscle gain and fat loss.
Fasting is one of the best ways to increase your GH and this means your body is ready to make new muscle tissue and burn body fat.
Growth hormone has been shown to improve overall bone quality, your physical abilities, and improve your longevity. There’s actually a study that shows if you go 24 hours without food, your GH production is up by 2000% in men and 1300% in women.
This spurs the argument of regularly fasting to benefit from an increased insulin sensitivity and growth hormone production.
