I was bulimic for about four or five months and went from 5'6.5" at 115 pounds to 95 pounds. I have not told anyone, and will not, so please don't ask me to, but I am back up to 110 to 112 pounds and pretty much graze throughout the day so I don't throw up. I mostly snack on white bread, fruit, potatoes, and cereal in large portions, but want to stop and eat a healthy, more balanced diet. The problem is, I am not sure what a healthy weight should be. Charts say I am too skinny, but I don't believe it because I know girls in the media are thinner than me and they seem fine. I want to be as small a weight as possible without being unhealthy. I skipped my period for three months but did get it in January. I have not lost any weight since then though, and I should have gotten my period about a week ago but didn't. I don't understand, it is so confusing, can you help me?

I'm an athlete, and about a year ago, I purchased one of those ab rollers. One time, I was going through the motions and I experienced an orgasm. Now, it happens about every time I use it. I thought it was extremely weird, but then read where women experience orgasms through lots of things. I was just wondering how it is possible for those feelings to happen just by working out my abs. Also, what are some other weird ways that women have had orgasms? Thanks so much.

If you freeze yogurt does it kill the active cultures, the good bacteria?

Despite medication, diet control, and exercise, I still have a ratio problem regarding HDL/LDL. What foods would you suggest to boost HDL, while reducing LDL?

I've been trying to diet for over two years. My goal is to lose about 25 pounds, but the most I've been able to get is 15, and I can hardly keep it off. I concentrate on eating very little and since exercise is so hard to keep up, I pretty much starve myself to death. I manage to maintain the weight for a month, and then I lose control again. I've been thinking about the various diet products in the market, such as diet teas, herbs, meal- substitution shakes, and other medical products. I'd like to know what kind of side-effects they have, and how effective they are. (Some boast a seven-day plan, but that seems hardly believable.) Also, I'd like to know how well-researched the information is on these products (i.e., are they long-term enough to cover all the side-effects?) As for aspartame, is it really harmless, or is it just not researched yet?

1) What's the deal with monosodium glutamate (MSG)? What exactly is it, and how bad is it for you really?

2) I have recently been told I have a strong intolerance to MSG. But I am having trouble in working out what it is in. Is there any chance you could give me a list of items of food in which MSG is present in? I would be extremely grateful for any help.
