Will I put all the weight on again at the end?
You'll lose weight fast for 15 days by eating a diet of lean protein and vegetables with low GI carbohydrates, keeping your GI index and calorie intake down. At the end of your beach diet, you'll need to reintroduce high GI foods back into your diet gradually, going for medium GI foods such as potatoes to start with, for example. To avoid putting the weight back on straight away, you'll need to continue eating low rather than high GI foods, not just for your bikini bod but for the good of your health!
