The Slim-Fast diet is a low-calorie meal replacement plan for people with a BMI of 25 and over. It uses Slim-Fast’s range of products. The plan recommends three snacks a day from an extensive list, including crisps and chocolate, two meal replacement shakes or bars, and one regular meal taken from a list of recipes on the Slim-Fast website. You can stay on the diet for as long as you want, depending on your weight loss goal. Once reached, you’re advised to have one meal replacement shake a day, up to two low-fat snacks and two healthy meals. The plan is designed to help you lose about 1-2lb a week and you can follow the diet for as long as you want.
Meal replacement diets can be effective at helping some people lose weight and keep it off. The plan is convenient, as the products take the guesswork out of portion control and calorie counting. No foods are forbidden, although you are encouraged to eat lean protein, fruit and vegetables.
On their own, meal replacement diets do little to educate people about their eating habits and change their behaviour. There’s a risk of putting the weight back on again once you stop using the products. You may find it hard to get your 5 A DAY of fruit and veg without careful planning.
If you don’t like the taste of the meal replacement products, you won’t stay with the plan. The Slim-Fast plan can be useful to kickstart your weight loss regime, but it’s important that you make full use of the online support to learn about the principles of healthy eating and how to manage everyday food and drink.
