For part of my life, I was extremely athletic, and after five kids, I did not have time for 6+ hours a day of exercise. Doing one hour per day seemed to do nothing to offset middle age metabolism combined with a high carbohydrate diet. The interesting thing is that once I switched to a keto diet, my body mass changed and my health improved significantly for the better. The interesting thing is that the keto diet is actually higher calorie than the high carbohydrate one. I suspect that telling people they need to exercise more is not helpful - most people will never be able to exercise at a level that will make a dent in their diet. A lot of people are eating 4,000+ calories a day of high carbohydrate diet burning 50-200 calories per hour. The math just doesn't work. The diet is where it is at.
