I had an 'aha' moment shortly after joining Weight Loss Buddy. 
I finally realized that even if others can eat junk foods, foods high in the (bad) fats and carbs and drink coffee and colas, I just cannot do it. My health and my body do not tolerate it! So my 'aha' moment was when I came to the conclusion, "Others may, I cannot!!!" 
I'm finding it is not so bad to think that way, so when I do eat the "wrong" foods I do it in moderation, filling up on vegetables and salad before I sample the pizza. I swap out a potato for a green vegetable at the restraunt. When I can keep my little motto of "Others may, I cannot," I make better food choices that are healthier for me.
