Said it before, I'll say it again: if you deny yourself, you'll find yourself eating more of the thing you denied when you finally get the opportunity. I've found that if I eat what I want, when I desire it, I don't eat a lot of that bad thing. Feel like wings, eat wings. I'll have a smaller portion now, and not want them again for a while. When I denied myself all that shitty stuff while I was unemployed, I gorged when I finally had money.
Then again, my diet, weight, and health are abysmal, so no one should ever listen to me about food and fitness!
Strangely enough, this is the approach I took my own weightloss / fitness.
The small twist is that I have more of an understanding of how calories work than I did before. I eat a lot more vegetables because they are lower in calories and filling, but with zero restrictions, just smaller portion sizes than before.
Weight training does help, but it's nearly impossible to do anything strenuous in this heat.
