Famine effect in terms of the body reducing movement to conserve energy and to increase hunger to encourage excess food input is not BS.
Famine effect in terms of slowing the metabolism sufficiently to overcome a calorie deficit so as to maintain weight at a plateau is BS.
Leptin is controlled primarily by two things, which are
a) Short term: acute energy balance. A high calorie deficit causes leptin to drop lower than what can be explained by fat loss, and a caloric surplus raises leptin higher than what can be explained by fat gain.
b) Long term: total amount of fat mass. Fat cells are factories for leptin production. Not having many factories obviously impairs production and the aboslute amount of leptin in circulation.
If a) can be manipulated via a subtle energy deficit and regular refeeds of the right macrocomposition (carb refeeds acutely increase leptin, while fat has no effect), this should prove beneficial to circulating leptin levels during the diet.
