Men who go through cycles of losing weight and then gaining it back may be compromising their bone health later in life. Researchers in Norway followed approximately 4,600 men aged 40 to 49 over 28 years and found that the more frequently a subject’s weight fluctuated before he turned 50, the more he was at risk for fractured forearms after age 50.

It appears that frequent weight loss and gain could increase bone loss. To maintain healthy bones, a man needs to consume healthy amounts of calcium and vitamin D throughout his life, especially if he is dieting. Osteoporosis Canada recommends 1,500 milligrams (mg) of calcium and 800 international units (IU) of vitamin D daily for people over age 50. A cup of milk or soy beverage contains about 300 mg calcium and 100 IU of vitamin D; these are currently the best sources of combined calcium and vitamin D.

Calcium is also found in other dairy products, fortified beverages, and salmon or sardines with bones. Vitamin D is found in fortified beverages such as milk and in fatty fish.
