Alpha13 saidi got lean by cutting out processed carbs and processed sugar.They are just not natural foods that our body evolved with I eat meat, veggies, fruit nuts,berriesand plie on the fat. .
"Fast carbs" are not bad. It's the insulin response, at the wrong times, that makes for a fat person. In fact, fast carbs (sugars) are a GOOD idea post workout for glycogen reload in the golden hour post workout.
It has EVERYTHING to do with insulin management. Bodybuilders learn how to keep their blood sugar moderately high with adequate amino acids (protein), with nice, stable, insulin levels, creating an anabolic, as opposed to catabolic state. It's not about miracle potions as many folks who fail would like to believe.
Fat asses get diabetic because they become insensitive to insulin (type 2 diabetes). They do that by keeping their blood sugar to high, and having too much insulin to much of the time.
All that sugar, and lipids, mct, and alcohol (the carbon) eventually end up as something close or exactly like glucose (blood sugar). Proteins repair the tissue.
Now, any scientist can tell you this is a bit simplified, but, it's the basics. You have carbon, and amino acids. We're carbon-based.
All that being said, real food has many benefits.
Starch (complex carbs) give you sustained glucose and sustained insulin levels in that they are tightly bonded and decay more slowly than sugars, causing fewer insulin spikes, but, may not be fast enough.
Our body will metabolize fat under the right conditions, BUT....not if our bodies are in famine mode. In famine mode, we metabolize PROTEINS (muscle) and carbs, and preserve our fat, as well as slow our metabolism.
Adequate calories are VERY important to maintaing a fast metabolic rate.
ONLY lean muscle mass INCREASES your base metabolism as you GROW OLDER. It burns calories sitting there.
