Decent Essays

Physical Activity versus Extra Sleep Obesity and overall health can be affected by both the amount of sleep you get, and with the amount of physical activity you do. Increasing your physical activity and the intensity you perform the activity will help fight obesity and improve your overall health. When a person loses weight their overall Active Energy Expenditure (AEE) is reduced, but with a reduced body weight people tend to be more physically active which will overcome the reduced AEE (Bonomi 2013). To reduce health risks a person must do more than just sleep, or be more active. Overall health in obesity subjects also comes down to life style modification and helping them maintain proper nutrition reducing Cardiovascular Disease Risk …show more content…

At the end of the study during follow up body weight was reduced by average 23.8kg, visceral fat area and fat mass were reduced by 30.8%, while only a slight reduction in fat free mass being 10% of total body weight lost. The relatively unchanged FFM was likely due to patients having done 90 minutes of physical activity 5 days a week (Danielsen 2013). In addition to having obese patients perform aerobic training they should also include resistance training into their routine. Increasing lean body mass will increase their energy expenditure and further assist in losing fat. Increasing muscle mass 1kg should increase AEE about 21 kcal/kg for new muscle (Strasser 2013). With the change in body composition obese patients are more likely to engage in physical activity (Bonomi 2013). Sleep can also be looked at to help the fight against obesity. Studies have shown that on short nights of sleep people consume more calories and most of the increase is calories from fat (St-Onge 2011). This study looked at people with a BMI of 22-26 on a short night’s sleep (4 hours), and a normal night’s sleep (9 hours). The level of activity in people on short versus long nights of sleep was not significantly different, however their increased caloric intake was ~300 on short nights of sleep, most of which were snacks (St-Onge 2011).
