What a meal replacement is

A meal replacement is a complete meal — protein, fibre, carbohydrate and a full spread of vitamins and minerals — built to a set, lower calorie count. It stands in for a normal meal rather than adding to it, which is what separates it from a snack or an ordinary protein shake.

What is in the range

Shakes, hot meals, soups, breakfasts and bars. Same nutrition, different formats — so you can have a shake on a busy morning, a hot meal at your desk and a bar when you are out, without eating the same thing twice.

Why it helps you lose weight

Weight loss comes down to eating fewer calories than you burn. Fixing the calories in each meal, and keeping the protein and fibre high, takes the daily maths and the guesswork out of it — you already know where a meal lands before you eat it.

Built around your plan

Meal replacements count as one meal on any of our diet plans, including a 5:2 fasting day. If you have not picked a plan yet, how it works walks through how many meals to replace and when.

Protein, fibre and cravings

Protein and fibre are the two things that keep you full between meals. Getting enough of both is the difference between finishing the day on target and raiding the cupboard in the evening — so every product is built high in both.

Ready when you are

Most take only hot water or a shake, a minute or two, and no cooking or washing up. That matters on a busy day: the easier a meal is, the more likely you are to stick to it.

Meal Replacement Q&As

Can I lose weight just by replacing meals?

Yes. Because each meal has a set, lower calorie count, replacing one or more of your daily meals brings your total intake down without you having to weigh or count anything. How much you replace is up to you and the plan you follow.

How many meals a day can I replace?

Anywhere from one to three, depending on the plan you are following. Many people replace breakfast and lunch and cook a normal evening meal; others replace all three on a faster day. Our diet plans set out sensible combinations.

Will I be hungry?

They are formulated high in protein and fibre for exactly this reason, so a couple of hundred calories holds far better than the same calories from ordinary food. Spacing your meals through the day and drinking plenty of water helps too.

Are they nutritionally complete?

Our core meal replacements are fortified with 20+ vitamins and minerals alongside protein, fibre and carbohydrate, so they stand in for a full meal rather than just cutting calories. Each product page lists its exact nutrition and any allergens.
