Low carb diets

The dietary guidelines in the Shape Up Challenge are designed for weight loss and health. There are people who will need more calories than are recommended (or less), who will be able to eat more starches or fruit than are on the recommended list (or less), but that's what customising a plan is all about. The percentage of calories coming from carbohydrates is a bit less than the nutritional pros would have you believe you should be eating, but if the 'official, government-approved' version of what you should be eating was working so well for you, you probably wouldn't be reading this in the first place.
