Questions about taking Black Powder by MRI?
I have bought some things like this for sale and my weight loss coach who is relatively new. Still learning all the rules. the question is that the instructions say to take the black powder on an empty stomach ... that either it does not make me sick or anything. However I have read that you not suppossed to exercise without having eaten anything before. So it does not effectively replace the black powder you need to have a snack. Or my body will get the carbohydrates of the muscle as well when you do not eat?
ive had similar to this product. trick is to have solid foods around 1-2 hours before you go to the gym so many complex carbohydrates, protein ... that way the food will not be in your stomach, but transferred to your gut. That way u will still have good levels of glycogen (it will be converted into energy for your muscles) in the muscle. then you can take your post workout shake within an hour of exercise You and eat within 2 hours of exercise you reason you should have it on an empty stomach is because when you have it with food, it will not be absorbed by your body as quickly and the whole idea is for the powder to provide a spike in the muscle so it does not have an imbalance of nitrogen.
