Hi guys

I have stopped weight lifting due to the fact that I am losing weight for who knows what reason. And I am 5'9 tall guy weighing in at about 113-111 pounds. I tried drinking Protien Whey mix drinks and those gave me burning stomach pains on and off for days and dry hard protein colored stool. I've decided to drink about 2 or 3 boosts plus a day. I am not sure if that is good for my health or what. But boost plus has more clarories and more soy protien than the usual boost. I am eating cannbed beans and mcdonalds daily along with water. Also I take a multi vitamin. I have to be careful as to not overdose on my vitamins. I think I ate to much vitamins yesterday and at night I had a really messed up reaction. I felt like I was having a bad trip on drugs for an hour or so.
I am just wondering if I should still continue weight lifting. I love to lift weights and my weight is really not THAT stable, it is not rising at all. Just kind of staying the way it is. Maybe I could do 15 minutes of weight lifting twice a week??

My GI doctor doesn't seem worried about me. I guess I am just a really thin person.

I am open minded to all your suggestions.

You should definitely keep weight lifting, but your diet sounds really bad. McDonalds is not a food group. It's barely food. :) You should probably be getting at least 2000-3000 calories a day (or more if you have a fast metabolism) and about 1g protein per pound of bodyweight. If protein gives you dry, hard stool, you need to get more fiber in as well, from oatmeal, veggies or even supplements if you must. Without proper protein, you won't build or maintain muscle mass which may be why you have lost weight. You don't necessarily have to have protein shakes to get in the protein you need. You can certainly get it all in diet alone (see the threads on high protein foods). Pre-made drinks like Boost are okay, but don't rely on them as a staple. They usually have a lot of sugar and still generally very little relative protein. If you weed out a lot of the junk, your body will be able to make better use of the nutrients you take in. Good luck!

Hi I have decreased appetite. I don't think I eat 3000 calories. I eat a small breakfast, a medium lunch, and a medium dinner. And about 2 boosts. I have not gained weight could that be just because I don't eat tons of food and I have fast metabolism?

Absolutely. I'm training a guy right now that has the most ridiculously fast metabolism I have ever seen and it is a huge challenge to get him to eat enough food to facilitate any muscle/weight gain. Going with calorie and nutrient dense foods that are not filling is the only way I can get him to gain anything. I'm having him snack on nuts and jerkey, protein shakes with 2T flax oil, weight gainer shakes post workout. Etc.

I agree, you need to be eating at least 2500 plus calories. Also how long have you been lifting? You are a "hardgainer!" I am sure an Internet search on hardgainers will help..
