I try to eat a piece of fruit for dessert after a meal; however, when I have substituted after-meal sweet cravings with fruit, I still end up craving some other type of sweets (i.e., candy, chocolate, ice cream.) It seems that after every meal, I can't feel satisfied until I have eaten something of this food category. I do try to listen to my body and this appears to be programmed into my mind telling my body it is wanting this food consistently. Can you provide any explanation as I am trying to lose weight and this type of food is empty calories and unhealthy? I work out six days a week and have recently given up smoking.

I get the apples provided in the dining hall on campus every day and have noticed that they are completely coated with wax (scratching the surface produces white flakes). I was wondering, how harmful is the wax if I eat two or three apples a day?

I have a question about walking for weight loss. My walking buddy believes the theory of walking distance is what helps you lose weight best versus my theory that it is the speed at which you walk that matters. So, could you help me figure this one out? Which matters most in ultimate weight loss: speed or distance?

When working out in the gym, machines, such as treadmills and stationary bikes, show how many calories you are burning. Are these calculations correct, or is it just something to keep the participants happy?

What are the advantages of eating five or six smaller meals per day, as opposed to three meals per day? I've heard it helps to lose body fat. Also, are there advantages to eating more of your calories early in the day?
