Weight changes, either loss or gain, are common during cancer treatment. Dieticians are a great asset in this area. Generally speaking, if you want to stop weight loss, choose snacks that are high in calories and protein such as nuts, trail mix, dried fruit, granola, peanut butter, hard-boiled eggs, or cheese. Drink smoothies, milkshakes, and nutritional supplements or bars to put more calories and protein in your diet.
If you want to prevent weight gain, which is particularly true for people with breast, prostate, or ovarian cancer patients, cut back on sugar-sweetened beverages. Limit your salt intake. Be aware that “low-fat” or “non-fat” doesn’t always mean “low-calorie.” Watch your portions. Try to walk daily if you can and if it’s OK with your doctor.
