Chronic lack of sleep and a lot of stress are the most serious factors of overweight. People who have little sleep and live in constant tension, are not likely to lose weight even on the most effective diet and fitness program.
The specialists at Yale University (USA) were watching 472 overweight people for 26 weeks. Everybody under test sat on a low calorie diet rich in fruits, vegetables and grains, and did fitness at least 3 hours per week. On average, the volunteers lost 7 pounds, but those who got not enough sleep and were often nervous, mostly lost only 3.5 pounds and less. The most successful in slimming were those who slept 6-8 hours and had a low stress level.
