Phase 3: REST! By far everyone’s favorite period of the HCG diet plan (and honestly one of the most critical as well). Caloric intake is returned to between 1200-1500/day, but the low fat and no milk portions of the diet remain to keep the body free of external unnatural hormones. This phase is initiated after about 43-60 days dependent upon the regimen followed. During this particular phase, HCG intake is halted, and a new diet plan called the “stability phase” is activated. HCG must be flushed from the body for a period no shorter than 23 days, before beginning a new regimen. This is necessary for your body to keep shedding weight and not simply adapt to the HCG intake, either from HCG drops or otherwise. Maintenance is another term often used for Phase 3, but it really doesn’t matter what it is called, Phase 3 is probably the most critical phase for people who are interested in losing over 30 lbs, since multiple HCG regimens are necessary. There are specific phase 3 foods that go well with it, but just avoid dairy and high fat foods and you will do well in this phase and be ready to start again. Some people actually continue to lose weight during Phase 3! Not surprisingly they come back into their HCG diet plan after 23 days even happier than when they left!
Hormone replacement therapy has been shown to have other beneficial effects. In a study women taking estrogen through HRT showed that the estrogen positively affects the prefrontal cortex by boosting the working memory. This suggests that estrogen may play a key role in certain frontal lobe functions in women.  Women using HRT after menopause have no additional weight gain compared to women who do not use HRT.  Also women who use HRT with an estrogen component show positive effects in their sex life (mainly increasing their sex drive and sexual sensitivity) but the effects are inconsistent across women. These sexual improvements may dissipate after receiving some forms of HRT for extended periods of time.
