And even at this point, leptin will still be slightly downregulated unless you gain all the fat back you lost. Leptin plays a large role in metabolism, so replace everytime I used "leptin" with "metabolism", and you have your answer.
Noi no no, your screen name is hysterical because you don't understand squat about physiology
Leptin will go up within 5 hours of high calories/carbs
The issue is whether or not the brain will get enough of a signal to reverse anything
That takes 1-2 days of maintenance calories depending on a host of factors.
A full diet break is different
