In a study of people age 65 and older, it was found that weight loss was connected to a higher mortality rates. What should you do with that information?
Could losing weight be dangerous? That appears to be the conclusion of a study by U.S. and Australian researchers published April 10. Having studied more than 19,000 people ages 65 and older in the U.S. and 70 and older in Australia, they reported that weight loss appears to be associated with higher mortality rates in both men and women.
All of the people in the study were considered"healthy older adults" with no known conditions that might lead to premature death, such as cardiovascular disease, cancer or dementia. And yet, over a four-year period, weight loss was associated with a 33 percent higher risk of mortality for men and 26 percent for women.
There's also the fact that obesity is different in young people versus older people. That loss of lean body mass, mostly muscle, gives way to an increase in fat mass. This condition is called sarcopenia, and even someone with a"healthy" body mass index can be considered obese because they are carrying too much fat, not necessarily too much weight.
Diet: Protein, protein, protein. As we age, our bodies become less efficient at using protein, so we should be eating more lean protein. Research supports increasing the recommended intake of protein for older adults by up to 50 percent, .45 to .55 grams per pound of body weight. That's about 68 to 83 grams a day for someone who weighs 150 pounds.
Adequate sleep: An older person needs at least seven hours but no more than nine hours of sleep to let muscles rest and rebuild.
