Dr Jason Fung argues that much of what we think we know about weight loss is simply wrong.
Jason says that the critical factor in losing weight is hormones - not calories. He believes calorie counting is an overly simplistic approach. And that actually dieting may be the worst thing you can do, because it slows your metabolic rate which actually makes it harder to reduce weight in the future.
Jason argues medical science reveals that we all have what is effectively a fat thermostat in our bodies that tries to keep our body within a particular set weight. Try to reduce weight and our metabolism will do its very  best to sabotage this, making it harder for us to lose weight and easier for us to regain it.
If that’s case is there anyway we can reset this internal fat thermostat, so that we can lose weight? Or are we doomed forever to be caught in a vicious circle of dieting and weight gain?
Jason argues there is a solution. And it involves both changing what eat and when we eat.
Jason who is based in Toronto, Canada, is a kidney specialist and an expert on intermittent fasting. He believes that many of today’s chronic medical issues are related to diet and obesity. And says that  a dietary problem needs a dietary solution. He is the author of a number of best selling books,  the scientific editor of the Journal of Insulin Resistance, and the managing director of the nonprofit organization Public Health Collaboration (Canada).
