Im glad to see that this maybe something that you are looking to do and I think that it will definately help you; if you notice that the bit of peanut butter on that helps you throughout the day, perhaps inject some more of those types of food later in the day. It is all really a trial thing, if I were you though I would just try it; if its works perhaps change your diet to incorporate a bit more fat into it; REMEMBER, not all fat is bad and nuts are definately something that you should really look at. For instance, instead of Jiffy peanut butter, use natural skippy peanut butter which is better for you. These little changes will not make you gain weight and you will get more energy throughout the day as discussed before. Again if you have any other questions feel free to ask, your not alone I lost 60 lbs, and my diet changed so much that I became hypoglycemic as discussed before. I think this is something that you probably have and you will notice that there is a huge amount of increase in your energy throughout the day. Again if you notice it works, put some more in, if you are going to eat fruit or other things, make sure that you also have a fat with that type of food. For instance; peanut butter crackers with a banana, try to stay away from chocolate, do not have caffeine, the problem with these types of foods is that they give you a huge boost and then you crash causing you to be tired. MAKE SURE that you always have something to eat throughout the day and if you feel tired, eat it. Using this strategy instead of eating huge meals only three times a day makes it so your body always has energy and therefore you won't be as tired. This is what my nutrionist told me at least. Good Luck!
