Best meal plan for this is LCHF, which basically resembles VEGETABLE +
PROTEIN (meat/fish/
egg) + FAT. Make sure fat is
from natural sources, like olive oil, avocado, butter, coconut, etc, and not the fake stuff like margarine.
A typical LCHF meal looks like egg omelette with bacon, asparagus and mushrooms, or another example large salad with olive oil and steak, or another example broccoli sautéed in butter with roasted chicken thigh (with skin on).
