ask our dietitian your question todayfood for muscles


I am 28 years old, 125 pounds and I have ulcerative colitis so I eat healthy as much as possible…I need to gain weight and build muscle, what diet plan should I be on? What are my numbers that I should look for in calories, fats, proteins, and carbs? Water intake…FIBER? -Ateks



If you’d like to gain weight and build muscle, then you need to give your body more than it requires. Providing ample calories allows new cells to grow. To be sure they are muscle cells and not fat you’ve got to increase the resistance training in your workout regimen. Those calories should be from complex carbohydrates, lean protein and plant fat. Adding about 200-500 calories a day is all it takes. There are a few options to do this: maintaining your current meals and adding a sport shake; increasing the volume of your meals by 10-20%; or adding an extra snack to your day, perhaps at night.

Timing your fuel around your workouts is important.

We have a Healthy Living Blog article just on the subject! Read it HERE.

Focus on the added calories first, rather than attempting to fit your whole day into numerical goals. Let’s take an average of 350 calories to add. About 25% from plant fats (at 9 cals/gm) = 10 grams. Another 25% from lean protein (at 4 cals/gm) = 22 grams. The remaining 50% would be complex carbohydrates (at 4 cals/gm) = 44 grams. So what do these numbers look like in a shake or snack? A few weight gainer powders match these targets, others you’d need to mix with milk or adjust number of scoops. For real food here are four sample snacks:

  • 2 hard cooked eggs, 2 fat free waffles, ½ banana
  • 3 oz can water pack tuna, 1 tablespoon relish, 10 wheat crackers, 2 slices avocado
  • ½ cup soynuts, 2 hard Dutch pretzels
  • 3 oz. deli sliced chicken breast, 1 tablespoon pesto, 2 slices whole wheat bread


Water and fiber intake should meet recommended needs. Your fluids should total somewhere around 8-9 cups per day, including water and other beverages. Fiber should total 25-38 grams per day from fresh fruits, vegetables, beans, nuts/seeds and whole grains.
