The mantra of the government and food industry is that people should just eat less, choose a “balanced diet,” and exercise more. How’s that working out for you? Despite what popular magazines and TV shows might say, if you think you can exercise your way to weight loss, I am sorry to say you are in for a big disappointment. Using exercise to lose weight without changing your diet is asking for failure. You can change your diet and lose weight, but if you exercise and keep your diet the same, you may gain some muscle, improve endurance, and be healthier overall, but you won’t shed many pounds. I sat down with Dave Asprey last year to talk about fat, weight loss, coffee, and an article in The New York Times about the show, The Biggest Loser. This article caused quite a bit of controversy, because it essentially explained that some people are just destined to be overweight no matter what they do. Both Dave and I disagree with this idea and with the idea that eating less and exercising more is the way to your best weight. I hope you enjoy this conversation. Wishing you health and happiness, Mark Hyman, MD.
