You can run a flawless diet on six hours of sleep and still lose to a hormone problem you created in bed.

What short sleep does to hunger hormones
Restricting sleep raises ghrelin, the hormone that signals hunger, and lowers leptin, which signals sufficiency. Controlled studies consistently find that people eat several hundred extra calories the day after a short night, with the surplus skewed heavily toward refined carbohydrate. Nobody craves grilled chicken at 3pm on four hours of sleep.
The insulin and cortisol side
Even a few nights of restriction measurably reduce insulin sensitivity in healthy adults, meaning the same meal produces a larger glucose excursion. Cortisol rhythms flatten too, which affects appetite regulation and where the body prefers to store fat.

Get SodaSlim — From $49The training cost
Poor sleep reduces power output, raises perceived exertion and slows recovery. The session you drag yourself through on five hours is worth measurably less than the same session on eight — and you are far more likely to skip it entirely.
The caffeine complication
This is where a stimulant supplement needs care. Caffeine has a half-life of roughly five to six hours, so an afternoon dose is still meaningfully present at bedtime. This is precisely why SodaSlim is a morning capsule. Taking it late to chase energy trades tomorrow's appetite control for today's alertness, which is a bad deal.
