For diet wise stay away from all milk products and wheat products. If you are having protein shakes make sure that it isnt milk based which is pretty much 99 percent of them out there I use a kind called "Vega" http://myvega.com/ its the best product out there and taste better then most out there that are vegi based. Its pretty expensive but health wise its worth the buck. How tall are you? Im 6 foot 175 pounds really low body fat you could never tell i have colitis. Another piece of advice is go in and see a acupuncturist it was the most life changing thing i have done do some looking into it and for some people it works some people it doesnt for me it has cured a something doctors said would never be cured. I was in the hospital for a month last year and they had the operating room waiting for me and since then I have went to a natural path doctor to see what my foods i should stay away cause everyone has sensitivites they can help you find out what they are and what to stay away from. The thing is with colitis is if your goal is to be 250 full of muscle its never going to happen without a major fallout bro. You have to be on top of your diet very little sugar excluding fruit and veggies. Sugar is a killer for us and stay away from alcohol another killer because of the sugar content. Dont eat 3 hours before you go to bed and make sure to give your food a extra chew so your body can break it down easier. Get on a good vitamin program i stick to anything all natural get your b vitamins and a good multi and a fish oil that is enteric coated so it gets released in your system and some spirulina which is great for your immune system. I was 215 pounds of solid muscle before i developed colitis im 175 pounds now but i feel amazing but the trade off is to loose muscle health is key here you feel good you look good. Once your sick the way i was it changes you and you realize health is everything not the extra muscle thats more of a ego thing. For me i stick to organic produce and stay away from anything that is altered in any way no hormones in meat and alot of veggies. STAY AWAY FROM DAIRY<CORN<SUGAR<WHEAT best advice i can give anybody with digestive problems. Avoid tabs i dont know what the sides to your already weak digestive system. I have had low test ever since i was on prenisone 3 years ago i tryed to do it the natural way which worked alright but couldnt get me over the hump. No side effects from the test yet im 6 days in and i can tell by strength and i feel amazing not as tired and dont have that down feeling you know what im talking about. Colitis never effected my sex drive in anyway luckly but thats increased also. Instead of brown pasta go to a brown rice past or a wild rice pasta its easy on your stomach to digest. Any more questions feel free to ask i have spent thousands upon thousands of dollars on colitis for myself and trust me diet is everything no matter what a doctor says.
