- Winning a marathon has absolutely nothing to do with how fast someone runs the first mile, nor does quick weight loss mean permanent weight loss.
Like a sprint, an intense diet will shed pounds quickly without the need to change fundamental eating habits. At the same time, I would never try to sprint for more than a short time. Permanent weight loss is as different from dieting as marathons are from sprints. Champion marathoners are distinguished by their long period of training and preparation, not their fast starts. Like a successful marathoner, my weight loss was accompanied by deep lifestyle changes, reframing my whole outlook on activity and eating.
