Calorie restriction ‘significantly’ improves health in thin adults

Cutting Just 300 Calories Per Day May Keep Your Heart Healthy

Cutting 300 calories a day reduces heart disease, diabetes and dementia risks, study suggests

- Cutting your caloric intake by about 300 calories per day was found to provide benefits to the heart, even for those who are younger, maintain a normal weight and are generally healthy, new research suggests. About 610,000 people die of heart disease in the United States every year - or, 1 in every 4 deaths - according to the US Centers for Disease Control and Prevention. About 2,200 people in the US die per day because of cardiovascular issues, or once every 40 seconds.

"Just be cognizant of what you are eating, how you are eating and the amount of calories that you are putting in", said Pieper.

Researchers have discovered proof that only a modest decrease in our every day caloric consumption may have protective advantages for our hearts, based on a paper published this week in The Lancet Diabetes & Endocrinology. That landmark project, supported by the National Institutes of Health, was one of the most in-depth efforts to measure the long-term impacts of caloric restriction in humans.

On a calorie restriction diet, people - or lab animals, from which we get much of our current data on long-term calorie restriction diets come - people are supposed to get all the same nutrients they would get from their typical meals. In the end, 188 participants completed the study - 117 with caloric restriction and 71 without. People in the diet group ate three meals per day at a study center and received nutrition counseling, while people in the control group continued their normal diets and did not receive any counseling. Another way to try to cut calories is to avoid snacking after dinner. But the researchers found that even that drop, which translated to about 200-300 fewer calories per day compared to baseline, was associated with "persistent and significant" improvements in cholesterol, blood pressure, blood sugar markers and overall metabolic health, all of which are associated with a lower risk of chronic disease. They also saw improved insulin resistance and metabolic rates.

"There's something about caloric restriction, some mechanism we don't yet understand that results in these improvements", said study author Dr. William Kraus, a cardiologist and professor of medicine at Duke University School of Medicine in Durham, N.C. "But. we didn't expect the degree of improvement we saw". "Weight loss is best supplemented and sustained by increasing activity". In previous animal studies, calorie restriction has been shown to increase both the life span and health span, which is defined as the period from birth to the time at which one develops a disease.

"To our knowledge, this trial is the first, adequately powered two-year dietary randomized clinical trial to show such a profound effect on lowering all cardiometabolic risk factors beyond normal levels, even in rather young, lean individuals", Ravussin said.

Contributors had been requested to take care of the 25 % calorie discount for two years. (Small sample size was a limitation of the study.) Many others were screened out from the initial study pool because of concerns about their physical or mental health.
