This will be a simple, though I hope compelling post, which I hope will clear up some confusion in those concerned with diabetes/weight loss (which are inextricably linked).
So, it’s the calories right?
Well consider this - 200 calories of bread versus 200 calories of butter.
Eat the bread and blood sugar/insulin rockets.
Eat the butter, no effect on blood sugar/insulin.
Insulin takes out the glucose, insulin remains high - blood sugar crash.
Butter satiates, body can access stored fat, no hunger.
Blood sugar crash - you have to repeat the carb cycle cycle and are permanently hungry and don’t lose weight, T2 diabetic sugars all over the place
Butter eaten - body loses weight, blood sugar normalises.
Still think it’s the calories?
