Norwegian scientists have conducted a study on the interconnection of the weight and duration of life. It has occurred, that in 90 percent of cases too little weight and a too thin figure reduce the duration of life by 9 years, while excess weight and obesity reduce life by only 4 years. Obese people suffer from cardiovascular diseases, diabetes and articular diseases much more often than thin ones. Too thin people are more prone to malignant tumors, stroke and depression. So, it’s very important to be careful with dieting and always know when to stop. It’s better to be more active in sports, than to diet.
