Exercise for Weight Loss: How to Exercise Effectively for Weight Loss? What Should You Pay Attention to? Below are four common mistakes in exercise-based weight loss.
NO.1
Believing that simply exercising more will achieve weight loss goals.While exercise burns calories, relying solely on it for weight loss yields limited results. Studies show that even hours of daily tennis can be undone by consuming just one or two cans of soda or a few pastries. Therefore, achieving lasting weight loss requires not only exercise but also sensible dietary adjustments.
NO.2
Exercising on an empty stomach is harmful to health. People often worry that exercising without eating first will cause hypoglycemia due to the depletion of stored glycogen, leading to symptoms like dizziness, fatigue, and palpitations, which are detrimental to health.Dr. Hupa from the Dallas Fitness Center in the U.S. suggests that moderate exercise 1-2 hours before meals (i.e., on an empty stomach)—such as walking, dancing, jogging, or cycling at a controlled pace—aids weight loss. This is because no new fatty acids enter fat cells at this time, making it easier to burn excess fat, particularly energy-producing brown fat. The weight loss effect is superior to exercising after meals.
NO.3
Persisting with 30 minutes of jogging per session is sufficient for weight loss. While jogging achieves aerobic exercise goals, its weight loss efficacy is minimal. Practice demonstrates that only when exercise exceeds approximately 40 minutes can the body mobilize fat alongside glycogen for energy. As exercise duration increases, fat contribution to energy expenditure can reach 85% of total consumption.Thus, exercise lasting less than 40 minutes—regardless of intensity—shows negligible fat consumption.
NO.4
Higher exercise intensity and more vigorous activity yield better weight loss results. In reality, only sustained low-intensity aerobic exercise effectively burns excess fat. This occurs because during low-intensity exercise, muscles primarily utilize oxidized fatty acids for energy, accelerating fat consumption.As exercise intensity increases, the proportion of fat utilized actually decreases. Near high-intensity levels, fat contributes only 15% of energy supply. Therefore, relaxed, prolonged low-intensity exercise or sustained activity maintaining a heart rate between 100-124 beats per minute is most effective for weight loss.
