It's really from treating thousands of men, I can tell you this. It's all about the carb. Not so much the fat, but it's all about the carb. Because, guys, when you eat carb, it spikes up your blood sugar, your insulin gets released, but then it stop working out as well. And then the carbohydrate become the fat in your love handles or your chest, and those become inflammatory. When it becomes inflammatory, that's when it reduces your blood flow. And, well, what I find out in working with thousands of men is that the moment they decrease their carbohydrate intake, their blood sugar drop, their hemoglobin A1C drop, which is a measure of your blood sugar drop, and then their testosterone increases, and they actually lose weight, but they have more energy. And guess what? Their morning wood return, and they find that they are firmer.
