The SlimFast diet has to be one of the most well-known diets around - which isn't surprising when you consider that it's helped thousands of women lose weight over the past three decades. The plan encourages healthy and steady weight loss that has long-term results.

What is SlimFast?

SlimFast is a meal replacement plan that allows you to eat up to six times a day. Its most famous products are the milkshake-style drinks that you have instead of breakfast and lunch. SlimFastclaim you can lose up to 7lb during the first week and a steady 1lb a week after that.

How does SlimFast work?

The SlimFast plan is simple and easy to follow. You replace breakfast and lunch with a SlimFast meal replacement and eat a healthy 600-calorie meal in the evening.
You can also have three 100 calorie snacks throughout the day, for example fruit, a yogurt or a SlimFast snack bar. Each SlimFast meal is nutritionally balanced so you don't have to take additional vitamin supplements, unlike many diets.


SlimFast is good for people who lead busy lives or who often eat
on the run. Because the meal replacements are pre-packed, there's no
need for weighing portion or counting calories.

What are the drawbacks of SlimFast?

The plan is portion controlled, so if you are used to large portions you
may struggle during the first few days. If eating out in the evening
you also have to try and keep within the 600 calorie limit, or miss out a
few snacks in the day to allow for the extra calories.

What do you do on the SlimFast Diet?

SlimFast products are sold in most major supermarkets, Boots and
Superdrug stores. You will need two meal replacements such as soup or
shakes per day plus up to three snacks. For your third meal, you eat a
healthy, low-fat meal of 600 calories.

Piece of fruit
