150 minIwkj1 of moderateintensity
PA for overweight and obese adults to improve health; however,
200-300 minIwkj1 was recommended for long-term weight loss.
Evidence supports moderateintensity
PA between 150 and 250 minIwkj1 to be effective to prevent
weight gain. Moderate-intensity PA between 150 and 250 minIwkj1 will
provide only modest weight loss. Greater amounts of PA (9250 minIwkj1)
have been associated with clinically significant weight loss. Moderateintensity
PA between 150 and 250 minIwkj1 will improve weight loss in
studies that use moderate diet restriction but not severe diet restriction.
Cross-sectional and prospective studies indicate that after weight loss,
weight maintenance is improved with PA 9250 minIwkj1. However, no
evidence from well-designed randomized controlled trials exists to judge
the effectiveness of PA for prevention of weight regain after weight loss
Guidelines (101) recommend a minimum weight loss of
10%. However, there are also numerous studies that show
beneficial improvements in CVD risk factors when weight
loss is less than 10% (16,38,56,80,114,150). In fact, beneficial
improvements in chronic disease risk factors have been
reported with as little as 2-3% of weight loss (30,45,85,141).

moderate-intensity PA for long-term weight loss,
