The optimal amount of physical activity necessary for weight loss, maintenance of weight, and prevention of weight gain is unknown, and likely differs for each person depending on caloric intake and phenotypic expression (Kruger et al., 2005).
Now it appears that adults need at least 60 minutes of physical activity of at least moderate intensity at least 5 days per week to reduce weight and 90 minutes of physical activity of at least moderate intensity at least 5 days per week keep it off.
And findings show that physical activity combined with reduced caloric intake appears to be the most effective strategy for initial weight loss (Miller et al, 1997) and weight loss maintenance (USDHHS, 1998).
In a review of the role of exercise in weight regulation (King & Tribble, 1991), physical activity was found to play a greater role in promoting post-weight loss stability than was dietary restriction.
A severely obese child is unlikely to accept exercise of sufficient intensity to have a major impact on energy balance, but nevertheless, exercise helps to conserve lean tissue and might counter the decrease of metabolic rate associated with dieting alone (Shephard, 2005).
5. Provide recommendations for dietary changes and increases in physical activity that can be implemented within the family environment and that foster optimal health, growth, and development (Daniels et al., 2005).
Such results, however, are achieved in individuals who are motivated to seek treatment, and the findings might not apply to children with no strong desire to reduce food consumption or increase their physical activity (Shephard, 2005).
There is ample evidence that theory-based interventions that include classroom curricula, PE curricula, changes in school meals, vending machines, and cafeterias, and after-school programs, can increase physical activity and improve dietary patterns in children and adolescents (Daniels et al, 2005).
