I have one word for you P90X ! I had to take predinsone about 3 years ago for 2 months and it made me gain a lot of weight. Everybody asked me if I was pregnant because the weight was mainly in my gut. I hired physical trainers, etc and nothing worked.
2 1/2 years later I looked the same
Until.....I started P90X! I now look even better than I did before I took the predinsone and it's much cheaper than a physical trainer that I had before. I didn't go by their diet plan, I go by my own because I know I can stick with it. Here is a rough example of what I eat daily.
I only drink water after breakfast
Breakfast
2 hard boiled eggs
coffee
8oz glass of fat free milk
snack
small amount of almonds
string cheese
Drink a liter of water throughout the day before lunch
Lunch
grilled chicken salad with no dressing many variations such as grilled chicken with blackberries and almonds or grilled chicken with cucumbers, tomatoes, a little cheese. Instead of using dressing, I really marinate the grilled chicken well in a low fat homeade marinade that gives it a lot of flavor.
snack
choboni greek yogurt drink a glass of water with this snack
dinner
I can pretty much have anything, just in the appropriate portion size.
snack
banana with 1/2 teaspoon of melted milk chocolate or 1/2 teaspoon peanut butter. Drink a glass of water with this snack
The key of my eating is to eat very low or no carb the first 3/4 of the day so that I don't get the sugar crash that makes me hungry all day long. This way, I don't get hungry. Eating a lot of protein will help you stay full, for example choboni has 14g of protein.
I stay very full on this plan....I'm the type of person who is always hungry! Not on the above plan!
