Have you ever, unsuccessfully, tried low-calorie dieting? There are very good reasons why it doesn't work, but somehowthey remain a secret... After more than 35 years of clinical practice and helping many hundreds of patients to live at their ideal weight, Dr John Mansfield was able to share his unique approach: weight gain is a condition that has specific causes that can be identified and tackled, and which will be individual to YOU. Discover: - why there is no one-size-fits-all diet that works long term; - how low-calorie and low-fat dieting contribute to weight gain; - how refined carbohydrates result in 'hyperinsulinaemia' and weight problems; - how gut yeasts can make matters worse; - how to tell if your thyroid is also part of the problem; - most importantly, the significance of individual food sensitivities: how to identify and tackle what is specific to you.
