So before we go into the several steps you're going to take lets begin by explaining how fat loss works.
Your body has energy is stored as glycogen in your muscles and in your liver by converting carbohydrates and sugars to glycogen. As long as you have these stores high your body will never touch its reserve fuel which is stored as fat. So the goal here is to allow the body to use the reserve stores fat for fuel so you can lose fat rapidly. If your overweight odds are that you have a fatty liver and you are insulin resistant. The first goal should be to clean up your fatty liver so your liver can function like it should and help your body burn fat.
A lot of times we begin our weight loss journey not starting right. We do not account for fixing a fatty liver and our body's current state of insulin resistance.
