Różne obszary tłuszczu mają różną dystrybucję adrenoreceptorów (alfa i beta). Odpowiedzialne są one za metabolizm komórek tłuszczowych i przepływ krwi przez komórkę tłuszczową. Alfa-2 to te najbardziej "upierdliwe" (hamują lipolizę i przepływ krwi), znajduje się ich sporo w tkance tłuszczowej podbrzusza i ud. Receptory te można próbować zahamować dietą. Z UD 2.0:
As it turns out, there is a dietary way to inhibit alpha-2 fat cells: raising blood fatty acids.
When you lower carbohydrates to 20% of total calories or below, blood fatty acids increase (as a
side-benefit, the catecholamine response to exercise is also increased when carbs are lowered this
much).
After 3-4 days of exposure to fatty acids, alpha-2 receptors become inhibited naturally
(without the side effects of oral yohimbe). Combined with aerobics, this is a potent way to get rid
of stubborn fat. It also explains the previous observation that low-carbohydrate diets make
mobilization/loss of women's stubborn fat easier: between the lowering of insulin and the fatty
acid mediated inhibition of alpha-2 receptors, those fat areas were easier to get rid of. Of course,
decreasing carbohydrates fits in nicely with our goal of lowering insulin in the first place.
So now we have large amounts of fatty acids floating around in the bloodstream. While
this will, in general, increase fatty acid utilization by the body, we can do more. By depleting
muscle glycogen with weight training (or even intensive endurance or interval training), we can
upregulate CPT activity and enhance fat oxidation in the muscle.
