(Dr. Tammy Chang and Dr. Caroline Richardson, The Conversation) — There is a longstanding debate in the research community about the importance of fitness versus fatness in health. Are exercise and improving fitness more important than eating well and maintaining a healthy weight?
Some researchers argue fatness does not affect health as long as you are fit, which means your heart and lungs are strong. And national campaigns like Let’s Move are focused on exercise for health without a specific focus on weight loss.
But for people who are obese, losing weight might be more important to their overall health than focusing on fitness. In fact, evidence shows that exercise alone is not an effective way to lose weight. Rather, effective weight loss is mostly about what you eat, though it should also include exercise.
As family physicians, we see obese patients who have heard the message to “just be fit” and have added 10-15 minutes of walking to their daily routine or have bought a Fitbit to track their physical activity. We applaud these efforts. (…)
