DEAR DR. ROACH: I am a 75-year-old woman with a weight problem. My weight used to fluctuate from 130160 pounds. Then I started to notice that I was losing weight slowly but surely on my regular diet. My doctor did not have an answer. Soon I got down to 95 pounds. My family urges me to eat more than I feel comfortable with. I weigh 104 pounds today.
