Food for Thought
When it comes to calorie intake and longevity, less is proving to be more. Researchers recently compared 18 people who had followed a nutrition-dense, calorie- restricted diet for an average of 6 years with 18 other participants of the same age who ate a typical American diet. The calorie-restricted group (CR) ate between 1,112 and 1,958 calories per day, whereas the control group consumed anywhere from 1,976 to 3,537 daily calories. The CR subjects were leaner than the controls in terms of body mass index (BMI) and body fat; they also had “markedly lower” levels of total and LDL cholesterol, triglycerides, fasting glucose, fasting insulin and blood pressure. Reporting in the online version of the Proceedings of the National Academy of Sciences, the authors concluded that long-term calorie restriction is highly effective in reducing risk for the major factors that contribute to heart disease.
