I am currently trying to revise my eating habits to eat less often (I'm a throughout the day snacker, and normally don't eat meals). Is it okay to replace cravings or "boredom eating" with herbal teas? I was told that tea is a no calorie drink, and yet it fills me up when I'm hungry. I have started to replace most of my cravings with tea now, so that I actually eat a lot less than before. Is tea healthy for you if it is no caffeine, herbal, and I use honey to sweeten it? I am not used to drinking much of anything in the day and am fairly slim, so could the extra water intake have any weight gaining effects on me? Could this be a healthy diet?

I have been chewing and spitting large amounts of food (pretty much always sweet stuff — pastries, chocolate, etc.) almost every night for eight or nine months. I am eating a healthy, balanced diet otherwise, maybe a little on the lower caloric side (1300 to 1500 calories per day). My chewing and spitting sessions usually follow a balanced meal. I know this is a type of eating disorder. I have done a lot of research online and I know that there are side effects, although they vary depending on who you ask. Some sites mention that chewing and spitting activates the release of insulin and results in hyperinsulinemia, insulin resistance and weight gain. Is this true? How long would it take to develop these problems? Are these reversible if I were to stop this behavior?

I've read a lot lately about midnight snacking and late night eating and obesity and calorie worries, but my problem lies in the opposite direction — I'm LOSING weight, and insatiably hungry, day and night! The only advice I get is, "Eat healthy," which is preaching to the choir, since I consume more fresh produce, mostly vegetables, and home-cook all my own meals. At a recent nutrition check-up, the nutritionist patted me on the back in congratulations for having one of the healthiest lifestyles he's seen, and shrugged at my inexplicable hunger. The fact is, I'm in the kitchen every other hour, and my body doesn't differentiate between awake and asleep anymore when it comes to hunger. I go to bed on a full stomach, and wake up every three hours to eat again. It's exhausting! I'm falling asleep during the day — but never more than an hour, because hunger strikes. And amid all this, my grocery bill climbs and my weight drops. I don't get it. What am I doing wrong?

I just got a diet tea that contains senna. How is this herb bad for your health? Is it unsafe to drink it everyday to lose weight?

Thank you very much.

I've heard of body suits that increase sweating during exercise. Then I heard that Saran wrap had the same effect. I want to shed pounds but first I wanted to know if wrapping plastic wrap around the stomach helps burn fat during exercise.

I am a 22-year-old male. I would like your advice as to how to increase my weight. I am extremely thin, and would like to put on weight for both appearance and strength purposes.

I believe that thin people have a very fast metabolic rate. Is there any way of slowing this rate down? Does it fall naturally with age? I have often been told that I should lift weights, but cannot find time on a regular basis to do so. I do, however, have time to do push-ups at home.

Anyway, I'd much appreciate it if you could give me guidelines as to how to increase weight, especially through diet. What kinds of food should I be eating? How many times a day should I eat? How big should the meals be? I hear the soybean is very nutritious — is this true; if so, what could I eat or drink that contains soy?
