…During bouts of exercise our muscles require glycogen in order to perform and function at their best. Our bodies get glycogen from the carbohydrates we ingest.
A low carbohydrate diet will result in low muscle and liver glycogen stores. When muscle glycogen stores are low, your body relies heavily on protein and fat for fuel. Eating nil carbs may sound a good strategy for fat loss but sustainably it isn’t. Low muscle glycogen will result in your body breaking down muscle tissue to use as fuel. Put simply, we lose muscle.
Muscle requires high maintenance meaning your body needs to burn a lot of calories to maintain it. The more lean muscle mass you have, the higher level of maintenance required and the more maintenance calories your body will need to keep burning around the clock. Even during sleep your body is burning calories to maintain your weight.
This process (the amount of energy/calories your body burns each day to maintain your weight without any form of exercise) is called your resting metabolic rate (RMR). A loss of lean muscle mass (good weight) lowers your RMR as your body no longer needs to burn as many calories to maintain its lower weight. A reduced RMR results in more of the foods you ingest being stored as body fat. So remember, carbs are important and are certainly not the enemy.
If you read this article and want to find out more about RMR and diet don’t hesitate to ask me or any of the Immortal PTs.
Thanks for reading and keep smashing your training sessions.
