> Meat is considered a complete protein source, meaning it contains all nine essential amino acids that your body cannot produce on its own
Do carbs?
> Carbohydrates primarily provide energy for your body and are not a significant source of amino acids. Essential amino acids, which your body cannot produce on its own, are primarily found in protein-rich foods such as meat, dairy, eggs, and some plant-based sources like quinoa and soy
So you're 100% wrong: carbs do not provide essential amino acids and meat does.
The mechanism behind type 2 diabetes is well known and it's all about eating too much carbs.
Sugars and carbs are converted to glucose in your blood.
You can't have too much (or too little) glucose in blood.
Some of it is burned as fuel but the rest has to be removed somehow so body starts producing insulin to push glucose into cells where it's get converted into fat.
If you can't produce insulin, you have type 1 diabetes and need insulin injections.
If you overeat carbs you store more and more fat. You become over-weight and insulin gets worse at moving glucose from your bloodstream.
The diagnostic test for diabetes is literally: do you have too much glucose in your blood (compared to what is healthy range) or related test a1c which tests for elevated levels of insulin in your blood.
If you know the above, then how in the world can you claim that carbs are not the problem? It is literally the thing that causes diabetes.
The simple solution to reversing type 2 diabetes is therefore to stop eating carbs. That's low carb diets like keto or carnivore.
You make very wrong assertions (carbs are not the problem; carbs have all macronutrients; low carb diets are bad) without a single supporting argument or reference.
