(You can be forgiven for looking at the book cover and thinking: "mmm.... 50 shades of fat loss ") So...you want to lose some weight? (You're perusing the diet book section - it's hardly a Sherlock Holmes deduction.) But which diet do you go for: low carbs; low fat; meal replacements; protein only; points; blood group; soup; fasting; double choc muffins? (Okay, we made the last one up.) Chances are you've already tried a few but they've not worked (otherwise you wouldn't be looking for another diet). But why turn your life upside down by trying to follow someone else's complicated diet plan...
