Slim and save is the same principle as lipotrim, similar weight loss,.. you order your sachets online either 3 or 4 a day depending on how you want to do it. You can have a massive variety of shakes, meal packs (which turn into a baby food type of thing, but better than no food!), bars (which are LUSH!) and soups. It's much more flavoursome and doesn't make me feel sick in the slightest. You're allowed 500ml of coke zero a day too which is a real bonus for those water-haters. The required water intake for s&s is really similar to lipotrim. I really do prefer it! If you only have the 3 sachets of food a week which costs 29.99, you have 100g of protein a day and 200g of certain veggies. If you have a bad food relationship it's good as it MAKEs you behave but doesn't make you feel deprived!
