The general rule is to eat no more than 55-65g of carbs per meal. Eat three meals a day.
If you don’t eat enough carbs, your liver starts making the blood sugars you need, and that’s not what you want happening.
the dietitians say divide your plate into 3. Put veggies, meat, a carb-(potato, rice, pasta) on each division.
All veggies provide you with is mostly fiber and some vitamins. they don’t effect blood sugar.
Meat gives you minerals proteins and fats, and also does not effect blood sugars.
complex carbohydrates provide you with starch which is converted to glucose, which is directly converted by insulin produced in the pancreas to energy your blood carries to the cells in your muscles.
Gotta have it.
I had a spare tire and a BMI of 27 when I ate meat. I now have a 6 pack and a BMI of 20. You can talk all you want about mankind “needing” to eat meat, heck, the 60 pounds of fat I lost probably would agree with you. They want to make a return.
BTW, I get my b12 from yeast, my protein from the massive amounts of soy shakes I drink and my iron from eating fruits and vegetables. Haven’t touched dead animal flesh in a year and a half and I haven’t been fitter since.
