Basically, when we are in ketosis our body is using fat (ketones) to fuel everything. As such, we aren’t breaking down muscle to provide glucose. That is, muscle is being spared because it has nothing to offer; fat is all the body needs (well, to a large extent). For the dieter, this means substantially less muscle loss than what is achievable on any other diet. Make sense?
As a bonus, ketones yield only 7 calories per gram. This is higher than the equal mass of glucose but substantially less (22%, in fact) than the 9 calorie gram of fat from whence it came. We like metabolic inefficiencies like this. They mean we can eat more but the body doesn’t get the calories.
Even cooler is that ketones cannot be turned back into fatty acids; the body excretes any excess in the urine! Speaking of which, there will be quite a bit of urine; the drop in muscle glycogen, low Insulin, and low aldosterone all equate to massive excretion of intra and extracellular fluid. For us that means hard, defined muscularity and quick, visible results. Get keto diet pills
Regarding energy, our brain actually REALLY likes ketones so we tend to feel fantastic in ketosis. Clear headed, alert and positive. And because there is never a shortage of fat to supply ketones, energy is high all the time. Usually, you even sleep less and wake feeling more refreshed when in ketosis.
