Is Weight Gain Healthy?

In earlier decades, gaining weight during middle age was considered acceptable. But we know now that even a modest midlife weight gain will significantly increase your risk of heart disease. In a study which followed nearly 116, 000 registered nurses for 14 years, Willett, Manson, and colleagues (JAMA, 1995) found that even weight gain within the "normal" range, as well as modest weight gains after 18 years of age, appears to increase the risk of coronary heart disease in middle-aged women when compared to those who had not gained weight. The coronary risk rose to 25 percent among those who gained 11 to 18 pounds; 60 percent for a weight gain of 18 to 25 pounds and 200 to 300 percent increase for weight gains above 25 pounds. The source of calories-- whether low-fat or a more balanced low calorie diet-- did not have much effect on weight suggesting that it is overeating that is the problem. Further, Willett and colleagues found that people who exercise regularly are usually able to maintain their weight which suggests that exercise, not diet, should be the primary focus of efforts.

Similarly, Kannel, D'Agostino, and Cobb (1996) examined the relationship between being overweight and health outcomes using 26-year follow-up data from the Framingham Heart Study. They conclude that avoiding weight gain after the age of 25 is advisable to reduce cardiovascular mortality. Further, they suggest that weight control should be a national health priority as a means for preventing and lessening cardiovascular disease. Their analyses indicate that the optimal weight for avoidance of cardiovascular disease and prolonging life corresponds to a body mass index of 22.6 for men and 21.1 for women.

A few extra pounds is OK after age 65

After age 65, a few extra pounds could reduce your risk of disability and increase your longevity. Several recent studies confirm that small increases in weight after age 65 are protective. This extra weight (just 10%, don't overdo this!) may protect you from a hip fracture and give you that extra reserve for a hospital stay or for surgery.
