Q: I know that supplements for omega-3s and glucosamine are derived from animals. Are there vegetarian versions? A: Yes! Let's look at a few: Omega-3s Fish oil is the most famous source for these essential fatty acids, but it's definitely not the only game in town. Omega-3s are derived from one parent compound called alpha-linolenic acid (ALA), which actually comes from green plants. So a person or animal who eats green plants absorbs the plant's ALA and turns it into omega-3s; for example, fish get their ALA from green algae.

I seem to put on pounds more easily than other people, and everyone in my family has struggled with weight gain. Can I change my inherited “plump genes” without starving myself?
Q: I seem to gain weight so easily and lose it so slowly. Could I have a slow metabolism? Or thyroid problems?
A: It's possible, but let's start by defining our terms. The word "metabolism" means the speed at which your body burns calories. Even at rest, your body uses up some calories to maintain your body temperature and keep your brain working, your heart beating, etc. When you start moving around, your metabolism speeds up to keep pace with your muscles.
Q: I can't seem to get my cholesterol under 200, but I want to avoid taking medication. Does exercise really help?
A: Exercise can indeed help, depending on what kind you do. Think aerobic: brisk walking, jogging, singles tennis, cycling, dance workouts. Aerobic exercise has a small effect on total cholesterol, but it has a great effect on "good" cholesterol (high density lipoprotein, or HDL), increasing it by 10 percent or more. Exercise also reduces triglycerides (blood fats).
