Is body fat genetic?

I am a female, five feet tall and about 127 lbs. I am not satisfied with my size. I am not obsessed with weight but with the way I look. I am very strong and have plenty of muscle. It just happens to be covered by a thick layer of fat. Yes, it runs in my family. On my father's side everyone has trouble with their weight.

I am writing to you because I don't understand why I am not losing weight. I am a vegan. I have no dairy products and no fat content in my diet. Except for the occasional pat of margarine and fried falafel, I don't see why I haven't lost weight because I just cut the dairy products out about two months ago. I have been a vegetarian for 9 years. I ride a stationary bike twice a week in my target heart rate zone. I work out with weights and do calisthenics in my room every night. What is wrong? Is there another factor I am not considering? Glands? Do I just need to be patient? I like being big, I just don't want it all to be fat.

Thank You.


Does your metabolism slow when you hit 30?

I'm a 22-year-old woman. Many of my friends in their late 20s and early 30s (and older) have been warning me about an inevitable metabolism slow-down and subsequent weight gain around my 30th birthday. They say, "You just wait. When I was your age, I sat around all day eating pizza and I never gained a pound. Now I can't lose weight no matter what I do."

I am sure there's some truth to this, but I DON'T sit around eating pizza all day. I run three to four times a week and eat very healthfully. Will these habits ease the slowing down of my metabolism? Or should I expect some weight gain no matter what I do (as they say will happen)?


Is it better to spread out or binge alcohol consumption?

I am a healthy, fit, 18-year-old male. I have tried both ways: consuming small amounts of alcohol regularly (one standard drink a day) and consuming a lot of alcohol irregularly (10 to 20 standard drinks in one night, but only two days a month, or thereabouts).

I have tended towards drinking a lot irregularly because I have found that I can't notice any effects until I have had at least four or five drinks, 80 to 100 proof shots, usually mixed with soft drink.

I was wondering if either way was less healthy or more of a risk as the same amount of alcohol is ultimately consumed. Also, I noticed that I got a bit more of a 'beer gut' when I had one-a-day than 15 at once; is that likely or just my imagination?


Why did I get a false positive HIV test?

Dear Alice,

I recently had a routine HIV screening done for prenatal labs. It was positive. Thank GOD, western blot came out to be negative. My OB is reassuring me not to worry, that false positives sometimes come out in pregnancy, and as long as the western blot is negative — I'm negative. Could you explain a little more in detail as to why and if you agree with my doctor? I'm at very little risk otherwise and had a negative HIV test about five years ago and am with the same person (my husband).


How can I ask my partner if they have any STIs?

I really enjoy reading your answers on these pages, but here's the question that I haven't seen addressed on your web pages or anywhere else on the Internet. Can you please suggest some appropriate ways to ask a person with whom you're about to have sex if he or she has any sexually transmitted diseases? A few months ago, I met a girl with whom I had sex... and, as I found out later, she had herpes. We did use condoms anyway, but there was still some risk in catching herpes since we didn't use condoms all the time.
