Squeaky asked what kinds of foods you can keep on hand even when it's hot. Well, there's always jerky (whether beef or turkey etc.) although you have the nitrates to deal with there. I mention jerky because protein and high fiber foods tend to keep you satisfied longer and...it's a scientific fact that proteins have a higher thermogetic factor which means it takes more calories to break down protein than it does to process simple carbohydrates like pretzels etc. The fiber in apples and pears are great but they tend to not be quite so satisfying.

I suggest that if you're really serious about having good food and snacks available you invest in a small container and some freezer gel packs. Then you can have meals and snacks that your control the caloric and nutritios value of.

Does this help at all?
