30 Minutes Exercise Equally Effective as 60 Minutes for Weight Loss

Posted Oct 02 2012 10:22pm

When it comes to losing weight spending hours exercising may not be the most effective option. Mads Rosenkilde and colleagues at the University of Copenhagen (Denmark) conducted a randomized controlled study on 60 sedentary and moderately overweight young men to examine the effects of increasing doses of aerobic exercise on weight loss. Half of the men were assigned to exercise for an hour a day, while the second half only had to exercise for 30 minutes. Results showed that, on average, the men who exercised 30 minutes a day lost 3.6 kg in 3 months, while those who exercised for a whole hour only lost 2.7 kg. The reduction in body mass was about 4 kg for both groups. Furthermore, participants who exercised for just 30 minutes burned more calories than expected. “Exercising for a whole hour instead of a half does not provide any additional loss in either body weight or fat,” concluded PhD student Rosenkilde.

46. Hormone Health: DHEA
Dehydroepiandrosterone (DHEA) is the most abundant hormone in the human body. It is involved in the manufacture of testosterone, estrogen, progesterone, and corticosterone. The decline of DHEA with age parallels that of HGH (see Tip 43), so by the age of 65, our bodies make only 10 to 20% of what they did at age 20.
  DHEA supplementation has been shown in various clinical studies to enhance the immune response against infection. It also has been reported to be valuable against cancer, coronary artery disease, and osteoporosis. DHEA also increases muscle mass and reduces fat mass...
