Ketone Body Metabolism

Ketone body metabolism includes ketone body synthesis (ketogenesis) and breakdown (ketolysis). When the body goes from the fed to the fasted state the liver switches from an organ of carbohydrate utilization and fatty acid synthesis to one of fatty acid oxidation and ketone body production. This metabolic switch is amplified in uncontrolled diabetes. In these states the fat-derived energy (ketone bodies) generated in the liver enter the blood stream and are used by other organs, such as the brain, heart, kidney cortex and skeletal muscle. Ketone bodies are particularly important for the brain which has no other substantial non-glucose-derived energy source. The two main ketone bodies are acetoacetate (AcAc) and 3-hydroxybutyrate (3HB) also referred to as β-hydroxybutyrate, with acetone the third, and least abundant. Ketone bodies are always present in the blood and their levels increase during fasting and prolonged exercise. After an over-night fast, ketone bodies supply 2–6% of the body's energy requirements, while they supply 30–40% of the energy needs after a 3-day fast. When they build up in the blood they spill over into the urine. The presence of elevated ketone bodies i Continue reading >>

    I've done keto before, but this time I did it with EC stack.
    I started this monday at 194-196. Today I'm at 185.2-185.6.
    Is this too quick?
    Also before I forget, two weeks ago I did keto for 4 days and I got from 195 to 189, but I gave in and cracked and ate carbs, this time I have my motivations and goals set and I allow my self a cheat meal every now and then and have realized weight loss and control is an ongoing struggle, one meal wont kill me I just need to get back up and continue on, I can't lose all hope and just give up. It's this negative self limiting factor that would **** my diets up all the time.
    But as of today, this week I've gone from 195 to 185, is this mostly water weight, or is it fat? My parents have said my chest looks alot tighter and my face is a bit skinnier

    Mostly water bro. Caffeine is a diuretic. Make sure u are drinking over a gallon of water minimum per day.

    to be honest initial weight loss depends on CALORIC INTAKE, and carbs.
    if carbs are at 300g, your going to drop about 2.5 lbs in water. 5 at most. this is why i urge every one to eat keto at maintence calories so they can see how much they actually lose from dropping carbs, and fat will determin your rate of weight loss after.
