Something that I have found effective is to use things like vegetables as “filler,” and then end the snack with a small portion of what I really want. For example, you can start your snack by eating some cauliflower, which is so low in calories that it’s practically not even food, and then end the snack with a very small portion of chips or cookies or whatever. I’ve been using the 100 calorie snacks quite a lot for that, and some of them are actually quite good. They aren’t any better for you than their higher-calorie cousins–it’s mostly just that the portion sizes are smaller. But if you’ve already filled up on something like cauliflower or carrots, then you are good.
Fruit is also your friend, Despite being sweet and tasty, it’s usually pretty low in calories. I’ve been on a pineapple kick lately–get a fresh pineapple, cut it up, stow it in the fridge. A cup of pineapple chunks is only about 85 calories. That’s quite a lot of pineapple.
Salsa also has minimal calories. It’s a good thing to have with chips to help fill you up. I’ve been getting baked corn chips–they have a bit of a weird taste alone, but with salsa it’s hard to tell the difference.
Sounds like you eat dinner out a lot. Try scanning the menu for smaller portion entrees, skip appetizers (or just order an appetizer for dinner, but be careful, most are loaded with fat and calories!) and stick to the one beer followed by ice water rule.
Yep. Also, you can order larger things (and at some restaurants, all the portions are large, so it can be hard to avoid), but the trick is to evaluate the plate before you start eating, and decide up front how much of it you are going to eat. Physically portion it off–cut your entree in half, section off a portion of fries, whatever. It sounds silly, but this will seriously help you avoid overeating.
Also, go ahead and have the beer, but as Slainte Mhath says, stop after one. I think it’s a bad idea to completely deny yourself things that you really enjoy–it just makes it that much more likely that you are going to go off the diet. So let yourself eat things that you like from time to time, and focus on keeping yourself from eating too much of those things.
Livestrong.org has a great free calorie tracker, BTW, and also an iPhone app (not free, but its only $3 or so, and it works great–I highly recommend it).
