I thought eating excess carbs does that. It gets converted to fat by the excess insulin in the body when someone has insulin resistance. I understood the insulin resistance is what drives the inflammation.
Eating the right kind of fat is good for you. Being fat is an indicator of insulin resistance.
Cooling high carb food (pasta, rice, potatoes) for 24 hours helps via resistant starch. Reduces calories and is better re insulin.
“Does cooling starchy food after cooking really lower its calories?”
