I can give you the advise my doctor told me. Take the Canada food plan, follow it and it works. I lost 50lbs, averaging 2 lbs a week. I ate breakfast, lunch and dinner with specific snacks in between.
I worked on a 4 days meal cycle.
breakfasts included 1. Yogurt and a fruit 2. small bowl of cereal and a fruit 3. 1 egg sandwich (whole wheat) and a fruit 4. 2 fruit
Lunch included Salad most days with either a 8 oz protein (chicken, pork, beef, tuna etc) or a small starch (pasta or sandwich).
Dinner was always steamed or boiled veggies with a protien
snacks were either fruit or veggies
I cut down to 1 coffee a day...couldn't deprive myself of the morning coffee
drink water all day (this is a must)
Funny thing, the first two weeks I gained 3 lbs..then it started to fall off
I was a miss breakfast, quick lunch, big dinner guy. This has helped a lot, my knees feel better (I have had 7 surgeries) and dropped froma 38 waist to a 32/33.
I played Rugby at 250lbs until my early 30's and stayed around that weight into my late 40's, although my body shape and muscle density changed.
Good luck..
Cheers
