1. Diet is far more effective than exercising in reducing weight.
According to Dr. Samuel Klein of Washington University School of Medicine, "Decreasing food intake is much more effective than increasing physical activity to achieve weight loss." If you want to achieve a 300kcal energy deficit you can run in the park for 3 miles or not eat two ounces of potato chips." In a study comparing weight loss through diet and exercise, participants who reduce their caloric intake lost more weight compared to those who exercised alone.
2. Exercise is effective in fixing metabolism.
James Hill of University of Colorado shares that exercise is important in repairing a broken metabolism. Data from the NASA bed-rest studies support the claim that: days of non-activity causes metabolism to become inflexible. As soon as there is resumption of activity, a change in metabolism occurs. This supports that exercise is essential in maintaining weight.
3. Weight training is more effective that cardiovascular exercises in weight loss.
The American College of Sports Medicine's Health & Fitness Journal published in 2013 a scientific seven-minute workout that involves 12 body weight exercises that offers same benefits as 30-minute endurance training. In addition, a study in Obesity, claims that weight training allows one to lose more weight compared to cycling, running, or stair climbing.
Although these weight loss management models are backed by science, experts still advice a visit to the doctor's office.
