Diet diehards eat less to live longer
Motivated by animal experiments showing that underfeeding boosts vitality and prolongs life by 30%, the US-based Calorie Restriction Society is cutting down calorie intake in a bid to halt the ageing process. Society member Bob Cavanaugh: "Some people are doing it strictly to enhance longevity. Others do it to avoid age-related disease..." Professor Luigi Fontana has led or co-authored over a dozen studies on reduced calorie intake in humans. He is also studying longterm effects by monitoring a group of 50 adults who have been on calorie restriction diets for at least a decade - and so far their Diabetes and cancer rates are down.

Research: Cutting calories could lengthen life
Cutting the number of calories you eat daily could extend your life. Eating 300-500 fewer calories per day has scales down the aging process by lowering a thyroid hormone triiodothyronine, which has been shown in previous studies to slow metabolism and the aging of tissues. While persons in both the calorie-restriction group and exercise group lost weight and body fat, only those in the calorie-reduction group saw their triiodothyronine levels decrease. "There is plenty of evidence the calorie restriction can reduce your risks for many common diseases," said Edward Weiss.

Caloric restriction comes in a pill : with anti-aging benefits
Scientists have firm evidence that the anti-aging benefits of calorically restricted diets can be duplicated by a pill. In a study mice given resveratrol (the first of a class of longevity drugs) enjoyed improved health. Resveratrol didn't extend the lives of normal mice, but it did guard them from the ravages of time. "For the first time, we can mimic caloric restriction in an otherwise healthy animal. That's been the goal of the field for decades. We didn't know it was possible to let an animal eat whatever it wants, but still get the benefits. We now have evidence," explained David Sinclair.

Painless weight loss, cut 50 calories per meal
A sensible approach to weight control: switch from looking for major dietary changes to recognizing how differences of just 50 calories can add up to weight loss. Everyone's metabolism is a bit different, but usually each pound of body fat equals 3,500 calories. Cutting 500 calories a day should knock off about a pound a week. You can slowly but painlessly lose weight by cutting back just 50 calories at each meal to reduce your daily intake by 150 calories. If you can find 100 calories to comfortably trim from each meal, weight loss will move along even faster. You can then burn 100 calories more by sneaking in a little activity.

Weight loss through calorie restriction may lead to bone loss
Men and women who lose weight by cutting calories also may be losing bone density, but weight loss through exercise does not seem to have the same effect. Most U.S. adults are either overweight or obese. The primary treatment is lifestyle modification, including exercise and low-calorie diets. However, decreasing body weight is associated with decreased bone mineral density. Individuals in the calorie-restriction group lost an average of 2.2% of their bone density in the lower spine, 2.2% at the hip and 2.1% at the top end of the femur-all high-risk fracture sites.

Is a low-calorie diet the secret to longevity - restricted-calorie diet
We all know that cutting back on calories promotes weight loss, but does it also promote longevity? Many Americans seem to think so. Their beliefs are based on animal studies done as far back as the 1930s. The experiments show that eating 25%-40% fewer calories every day can extend animals' lifespan by up to 50%. The restricted-calorie diet limits the total calories a person consumes, while retaining a balance of nutrients, in the belief that that will slow down the aging process. This diet, which takes a lot of discipline, is not a weight-loss plan, although, that is one of its side effects.
