-Will GU (or some other simple carb) be converted more quickly/easily into muscle glycogen?[/quote]
The ingested carbs will provide energy faster than your body can strip it from protein, based on my experience. Once again, it is very simple to try it and see how you feel.
Oh, your body will know how to use the sugar all right. However the fructose in GU will not replenish muscle glycogen.
Yes, very simply. It’s not the AD that burns bodyfat, it is a calorie deficit. With the carbs, as with fat, it’s all about amounts. Don’t consume way more than you need and you won’t get fat.
For example, this morning I did some low-intensity cardio (hiking) for about an hour. 30 minutes before, I drank a serving of Surge Workout Fuel which contains 85 calories. The hiking burns a lot more than 85 calories. So I’m not worried about the SWF carbs converting to fat. And fwiw I have found that I actually burn more calories during training (e.g. 25% more) when I drink SWF beforehand. So it pays for itself calorically, plus I get the benefits of training more intensely and the adaptations that will result.
Yes. Look, in his later Metabolic Diet, Mauro DiP states that the carb intake should be tailored to your individual training needs and metabolism. See
Notice if you lack energy in training, you add carbs around the workout.
By the way, you should not think that when you eat carbs, you can’t burn fat. People can burn off bodyfat even when carbs are the dominant macro. You burn bodyfat when you burn more calories in a period of time than you consume.
[quote]How do you determine if a simple carb source can be fully burned during a workout?
Hope this clarifies what I am trying to learn, thanks for the input.[/quote]
As in my example above, I know that I will burn more than the 85 calories of a scoop of Surge Workout Fuel in an hour of hiking.
I obviously don’t know the bigger picture of your training and goals, but maybe the volume and intensity of your deadlift session isn’t the best fit for your desire to lose bodyfat.
Also keep in mind that the workout window is your greatest opportunity to shift your body comp in favor of muscle over fat. Your body is ready to elevate protein synthesis and replenish glycogen in muscle much more than any other time. The fatigue you feel is an indicator you are not taking advantage of that window.
