I'm what you would, in the bodybuilding world, call a hardgainer. No matter what I do I can't gain weight. I used to eat lots of carbs on a 4000 Calorie diet and nothing happened as far as weight gain. I would just get frequent urination and a fruitish odor in the back of my mouth and would occasionally go through periods of fatigue and tiredness directly after a meal, even if it wasn't loaded with carbs. This lead me to believe i might have type II diabetes. So, I bought blood a sugar monitor, and my blood sugar is always normal. Even after very high sugar meal, it was only 155 mg/dl, and went down to normal levels after about 2 hrs. Which lead me to that believe that maybe I have frequent urination because my body cannot produce enough enyzmes in time and begins to waste it. However, either way I then tried to increase the fat in my diet and still nothing. Now, since my symptoms are so close to that of type 2 diabietes, I'm wondering if my body cannot metabolize the fat due lack of insulin like Carbohydrates. I know that fats are emulsified and broken down and then absorbed into the bloodstream, but then what. I can't seem any info on what exactly happens after this point and how insulin is related to the storage and metabolization of fat in the bloodstream. Can anyone help with this?
