Low-carb diets have got it all wrong?

What's the truth about T3 and testosterone on low-carb?
The truth is that hormone levels rise when you eat carbs, because the body needs the hormones to fight the inflammation, that eating carbs causes in your body. What is considered a "normal" T-3 level today, would have been considered a high T-3 level 150 years ago, if they could have checked those levels back then, because they ate way fewer carbs, back then. Adrenal, thyroid, and other glands are burning out on today's high carb diet. Why do you think there is this epidemic of Type II Diabetes? Diabetes isn't a communicable disease. It's caused entirely by high carb diet. The higher testosterone levels found in people with high carb diet, aren't being used to build muscle tissue, but to fight the inflammation caused by eating carbs. Why do you think testosterone levels have fallen for young men over the years? Because the gland is burning out, because of high carb intake, and can't produce enough for guys in their 30s.
Hormones are made from proteins and fats. No hormones are made from carbohydrates. Carbs are not essential for human health, so there is really no reason to eat them at all.
"you feel lousy, spaced-out, sluggish, cranky...and maybe even sick," on an extremely low carb diet. Yes, those are withdrawal symptoms. They go away after a few weeks when you get over your carb addiction.
The keto diet is a high fat (70%) and Protein (30%) diet, with well under 10% carbs per meal. And that's what low carb fat loss diet needs to work in a reasonable amount of time. Diets with 30%+ carbs being called "low carb" is absurd.
If you don't want to live with the extremely low carb lifestyle, then fine, don't do it, but don't make up lies about it. The "food" industry wants everyone to pay high prices for cheaply produced carbs, and the "medical" industry profits mightily from you eating carbs too.
