Read about it here, ILS:
Pyrucet - Liquid (ethyl) Pyruvate/Aceatoacetate Mix
It inhibits fatty acid oxidation, promotes glucose oxidation by stimulating the activity of the enzyme pyruvate dehydrogenase (PDH). You may need extra magnesium with this. I'm suddenly wanting more watermelon.
So you're breathing better and have better exercise endurance, and you have to feed that with something like OJ, but overall I'm eating the same or less while doing more.
At a dose of one drop a day, I need about 10 oz more OJ a day, chugged soon after taking it. But my hunger for things like meat and fat has dropped substantially. I'm probably eating half to 2/3 the amount of meat I used to eat per day, same for fat away from meat. When I tried to cut fat before, it cut my energy too much and I couldn't do it without starting to hyperventilate all the time. Now it's just happening. No side effects so far.
I never calculated it until now but I'm probably getting an extra 140-150ish calories a day of OJ on this dose, but spontaneously cutting 275-300 fat calories, and I'm moving around more.
Seems to reduce my appetite for starch too. Yesterday, we all went to the same local restaurant for Thanksgiving dinner that we went to last year. Last year I had already been Peating for about six months, had no trouble eating the entire dinner. It's one of those places where the food's all organic and portions are relatively small (by today's restaurant standards). Yesterday I could only eat half of it. Same time of day, same breakfast as a year ago.
I'm pretty small, so you would likely need more than one drop a day.
