Oral contraceptive pills.
How do they effect fitness & Fatloss?
Progestin only OCPs show a greater tendency to cause weight gain in studies.
Traditional biphasic OCPs show less of an effect illustrating increased metabolic rate along with increased energy intake.
HRT in menopausal women indeed seems to result in weight gain, but does seem to spare the belly fat accumulation that can occur in menopausal women. This may be due to reduced amounts of estrogen and progesterone and their anti-cortisol impact. Remember cortisol encourages belly fat.
As stated previously, much of the impact of female reproductive hormones is a mute point if background insulin levels are too high. Their influence seems to be exerted only under low carbohydrate intake and consistent training states.
So, to take full advantage of this kind of phase training plan you need to ideally control your blood sugar level and be able to train consistently.
