My doctors have looked at the obvious: They have checked my thyroid and for any digestive disorders. I love food and eat a lot of pasta with veggies sauteed in olive oil. I also love cheese but don’t want to raise my cholesterol levels higher. Other than the weight loss, I’m in excellent shape.

Can you give me any suggestions?

DEAR READER: There are a number of common causes for weight loss, but you don’t appear to fit the norm. They include malnutrition, depression, chronic diarrhea, drug use, cancer, excessive alcohol consumption, eating disorders and loss of appetite. One thing that might be an issue is a dental problem or mouth ulcers. Should you have ill-fitting dentures or canker sores, this might be addressed. If you faint or feel lightheaded, sweat excessively, have increased thirst, palpitations, have hair loss are on laxatives or diuretics, these issues, too, might be considered. They may lead to an underlying cause that your physician has not addressed.

You might consider speaking with your doctor regarding a nutritional assessment and making sure that you have had complete laboratory analysis. A vegetarian diet is commonly a healthful one and far better than consuming fast foods on a regular basis. You might choose to speak with a dietician at your local hospital for some fine-tuning that will allow your weight to stabilize.

You apparently are burning more calories than you are consuming. A way around this is to supplement your meals with snacks throughout the day. Granola bars, fruit and raw vegetables would be good choices. I don’t know what your breakfast consists of, but you might consider making your own cereal with a variety of nuts, cranberries, honey and raisins. Top it with skim milk, and have a glass of orange juice and tea or black coffee.

There are countless ways of incorporating good foods into your diet without packing on the pounds, but it may take a little preparation on your part to make this happen.
