Glycogen is the unused and stored form of carbohydrates in muscles. When glycogen stores begin to peak from eating plenty of carbs, the body upgrades its fat-storing ability. Conversely, as glycogen stores are depleted, fat-burning increases. One way to kick-start the fat-burning process is to go extremely low-carb on two consecutive days every couple of weeks. This ensures that you tap into your glycogen stores for fuel, which signals the body to burn more fat.
Carbohydrates are almost as important as protein in the post workout shake. Carbs cause insulin release, and there is nothing better to lower cortisol levels that insulin. Insulin has an antagonist relationship with cortisol, meaning when insulin levels are high coritisol levels must be low. Also, since insulin is a storing hormone it will shuttle the amino acids from the whey protein directly into the muscle tissue.
A 2014 Harvard study found that men who did twenty minutes of daily weight training had less of an increase in age-related abdominal fat compared with men who spent the same amount of time doing aerobic activities, and other studies have shown similar levels of success when guys hit the gym to cut down on fat. The implication: Guys can cut belly fat most efficiently with weight training.
The prevailing formula for a long time on how much fat you’re going to burn was calories in minus calories out, based on your basal metabolic rate (BMR) and exercise efforts, explains strength and performance specialist Joel Seedman, Ph.D., owner of Advanced Human Performance in Atlanta. But with all the different biochemical reactions in the body, hormonal response, and endocrine function, there are an infinite number of factors that can affect how your body is storing and breaking down calories.
