Eating a lot of carbs does cause your pancreas to work hard to balance your blood glucose which can lead to Type 2 diabetes.
Not to mention fatty liver, fatty pancreas, pancreatic cancer, high triglycerides, acid reflux, insulin resistance, skin tags, leaky gut, autoimmune disorders, anxiety, depression, obesity, erectile dysfunction, constant hunger and carvings, dementia and much more.
Years of frequent or constant, high blood glucose levels is a poison to the body.
Usually the cause for fatigue on a low carb diet is not eating enough fat. Not getting enough fat calories results in weight loss. Your body still needs fuel.
I don't count calories or macros.
Exactly.
