DO WE NEED INSULIN POST WORKOUT?

Well, not necessarily, here’s the trick. Anytime you lift weights, the muscles will release calcium. This calcium release will trigger the GLUT-4 receptors on the muscles to prepare for absorption. Will it be as great as if you consumed a high GI carbohydrate? No. will it allow you to absorb nutrients AND keep insulin levels low to keep fat burning accelerated? Yes.

In summary, if you are holding onto a lot of body fat and reducing that is your primary goal, then stay away from high GI foods, even post workout. The calcium release following weight training will initiate the absorption of nutrients, which starts the repair process.

What is A GLUT-4?

GLUT-4 receptors are found inside both fat cells and muscle cells. Whenever insulin is released and binds to a cell membrane, GLU-4 receptors travel to the surface of their respective cells and allow for the uptake of glucose into the cell. These are the receptors that make it possible for each one of us to absorb nutrients. If you exercise, or ideally, lift weights, the receptors on muscle cells will become much more sensitive than those on fat cells if you don’t exercise or lift, then the opposite holds true, and fat cells are more likely to absorb glucose. Hence, making you fatter. So, we need to lift to increases the sensitivity of the muscle receptor sites and decrease the likelihood that fat will get its share of the glucose floating around
