Do You Want to Lose Weight? You Have to Do More Than Cut Calories
Do you want to lose weight? A new study suggests that cutting calories alone will not lead to substantial weight loss. According to the study, you need to combine diet with exercise to achieve this goal.
The research is published in the April edition of the American Journal of Physiology -- Regulatory, Integrative and Comparative Physiology and suggests that one's body adjusts to the caloric reduction and thus diet alone is ineffective:
In the midst of America's obesity epidemic, physicians frequently advise their patients to reduce the number of calories they are consuming on a daily basis. This research shows that simply dieting will not likely cause substantial weight loss. Instead, diet and exercise must be combined to achieve this goal...This study demonstrates that there is a natural body mechanism which conserves energy in response to a reduction in calories. Food is not always plentiful for humans and animals and the body seems to have developed a strategy for responding to these fluctuation.
