I've lost 8 pounds since January 1, trimming my weight from a (for me) bloated 175 to an almost reasonable 167. (I'm 5' 11" and 58.) I've done that as I gradually overcame old injuries and increased my training to where it is now, about 40-45 mpw.
Here's my typical daily diet:
BREAKFAST:
--1/2 cup of granola w/berries or banana and some 2% milk. (On midweek days when I've taken longer runs: same amount of granola w/a fair bit of yogurt, a couple of teaspoons of honey, and berries)
--cup of coffee with a fair bit of milk, no sugar
--vitamins w/3/4 of a cup of Naked green juice
LUNCH:
--microwaveable Campbell's soup or chili
--Chobani yogurt, the basic portable size (one cup? one-half cup? whatever it is)
--one or two pieces of fruit (apple, banana, cutie, etc.
DINNER:
--before dinner, a handful of milled baby carrots w/hummus dip
--a big Martini (500 calories)
--a big plate of salad: spinach, romaine, tomatoes, green pepper, cuke, canned corn, often some chicken breast, w/homemade vinaigrette dressing (x virgin olive oil, two kinds of vinegar, anchovies, capers, soy sauce, Worcestershire sauce, Grey Poupon mustard)
--occasionally, before dinner, a bit of Brie w/Triscuits
That's my usual daily fix.. I almost never have desserts at home. No obvious junk food except the Martini. No pig-outs on cake, cookies. Not a whole lot of gluten.
Occasionally a steak w/salad and a nuked potato. Occasionally Popeyes chicken, biscuit, red beans & rice--and I ALWAYS gain at least a pound, sometimes more, at the next morning's weigh in.
If I dropped the Martini, I'd have lost the weight a lot sooner.
I consider myself an omnivore. But I've wanted to lose this weight very badly, and so I found a diet that provides pretty high quality nutrition (except for the evil Martini) and that I actually enjoyed.
Lessons? Keep the high glycemic stuff to a minimum--except right after a long run, when, at least in the summer, I throw down a big homemade smoothie. NO SODA. Keep the sugar-based sweets to an absolute minimum. The Martini is a lot of calories, frankly, but I think it's better for weight loss than three beers with all their carbs.
Lots of water. Portion control! I measure the granola with a 1/2 cup measure that I keep right in the granola container. It's easy to overdo on cereal. I don't.
And here's the key thing: I'm never starving. I get hungry by lunch--and then I have lunch. I get hungry for dinner--and then I go home and have dinner. I don't snack between meals--although if I happen to stay home during the day, then I DO snack. So find a way of making snacking difficult.
Don't keep your vice-snacks around. I love salted mixed nuts, but they've very high caloric density and if I kept a can around, I'd gorge. Same with ice cream. I just don't bring it home. If you can't control yourself around a particular food, don't buy it and bring it home.
