My motto - Nothing tastes as good as thin feels
I've lost 25 pounds and will be thin when I lose another 15---I ditto every thing Grog said....take a look at this website: www. dietfacts.com . It will give you the calorie counts for food at your favorite restaurants. A super sized lunch at McDonalds is well over 2000 calories, more cals. that I should consume in one day!!!
When I'm in my weight loss mode I can usually lose a pound a week if I keep my calories at 1100-1200 per day. I have a food journal and I list every food and the calories for that food that I eat for the day. So if I have a big lunch I know that I have to go lighter at dinner. It keeps me accountable. I have a digital scale that weights the food, and when I punch in a food code that gives me calories for that portion. I think Salter makes it, I got mine at Linens and Things. Without that scale, I ALWAYS underestimate the true calorie count.
It sounds like alot of work, but when you get into the habit, it's really ok.
