Leptin is a major factor in metabolism and is effected during a diet phase. When fat mass
increases, so do leptin levels and appetite is suppressed until weight loss occurs. In this way, leptin regulates energy intake and fat stores so that weight is maintained within a relatively narrow range.
Leptins job is like a thermostat, it wants to try to fight to maintain at your bodies normal (body fat setpoint)… Changes in leptin can change the feeling of hunger, as well as changing energy expenditure. As leptin is secreted from fat cells, more body fat should mean more leptin. This should lead to a decrease in appetite and an increase in energy expenditure, therefore preventing us from accumulating too much body fat.
So during caloric restriction, the opposite occurs…
Appetite increases and energy expenditure drops. Therefore, it’s logical to assume that if we can keep leptin levels higher whilst dieting, the better off we will be. Now, how do you increase leptin you ask?
Increase calorie intake in a controlled manner!
NON-LINEAR APPROACH TO DIETING
Two words. Calorie cycling.
The idea is ridiculously simple. Essentially non-linear diets are those that have variable levels of caloric and macro-nutrient intake from day-to-day. There are endless ways to meet these criteria.
It’s all about having consistent bases to create a more anabolic environment in the body- and with the carbs, creating a higher training response, leading also to better conversion of T4, to active T3.
It’s good to keep the body guessing, and constantly evolving.
