Okay, here’s what I do. I basically do a modified Atkins; that is, heavy on the meat and fat and salads, few or no carbs (under 30 grams of carbs per day). It can be done, and you really won’t be too hungry once you get used to it.
I eat mostly any kind of meat (steak, roasts, ham, chicken), cheese, and Breyer’s CarbSmart ice cream (it comes in chocolate and vanilla, and it’s quite good). I also eat canned tuna: Bumblebee Solid White Albacore in water. Drain the water and add a tablespoonful of good mayonnaise. A whole small can of that or half a large can with about 3 oz. of cheese, five baby carrots, and as much celery as you want is actually a pretty filling, easy meal.
Salad is good as well. It fills you up and looks nice on your plate. Cucumbers, onions and some carrots in the salad are cool. Raw yellow squash is also good. Tomatoes, too. Keep to oil and vinegar dressing. I’d suggest light olive oil and red wine vinegar. Along the lines of salads, those McDonald’s premium salads are good, but stick to the Grilled California Cobb with your own oil and vinegar dressing. No croutons!!
And speaking of fast food, if you have to have it, get either the McDonald’s Double Cheeseburger or Quarter Pounder with Cheese and just eat the meat and cheese part. Honestly, it’s not bad that way!
Try to keep your caloric intake at about 1500 calories a day if possible, especially if you’re not working out. It doesn’t sound like much, and I suppose it isn’t, but you said you wanted to lose weight, and this should do it.
Now… you’ll pretty much have to kiss bread, pasta, rice and desserts goodbye if you do this like I do it; but, oh, I think it is SO worth it!! (I have some wine every so often, but regular boozing is pretty much out, too.) As they like to say around here, you mileage may vary.
This is how I eat. I am 5’9" and weigh 121 pounds, and I manage to stay that way. (To be fair, though, I have to mention that I also work out 30 minutes a day five days a week, which does allow me to cheat every once in awhile.)
Good luck and let us know how you do. Believe me, I know how much of a challenge weight loss —and modifying one’s eating habits— can be.
