You won’t be tracking proteins and fats because they don’t directly affect the expansion of your waistline. Why? Various breakthrough studies done at Harvard University over the past decade have clearly shown that the main reason you have belly fat is because you’ve been eating too much of the wrong carbohydrates—sugar and processed carbohydrates—not too much fat or protein. It’s that simple. You see, eating fats and proteins never significantly drives up the insulin level in your blood, which is the main way that your body likes to encourage the storage of fat—especially around your waistline. Bottom line: proteins and fat are processed by your body differently. This is why the secret is to track just your sugar and carb intake. Does this mean that

you can eat a whole cow or ten sticks of butter? No. You need to use common sense. But the good news is that proteins and fats satiate your hunger fast, so it’s almost impossible to overeat them. And as you will see with all of my CARB SWAP™ meals, my top pick for proteins is almost always a lean meat. And my top picks for fats come from egg yolks, raw butter, extra-virgin olive oil, flax oil, or fish oil.
