Delicious bars

Very filling and satisfying bars. Quite sweet but not too sweet. Pleased that they are more like cereal bars than protein bars

Substantial bars

These bars are very filling and taste good. Because they are so substantial they take a while to eat and you feel as if you have actually eaten something. 

Cereal Meal Bars

These are chewy and filling and taste great. Probably my favourite out of all the bars. Feel healthy eating them and they are easy to take out and about and tasty enough to stop you getting tempted with something else. I am starting to lose weight, feel great, my blood pressure has returned to normal and no more horrible acid reflux. I have one shake a day and either one bar or the desert and one healthy meal either lunchtime or evening . 

Cereal bar - fills you up

Fills you up but takes some getting used to taste and texture 

Fills you up

Taste and texture take some getting used to. It isn’t bad just isn’t particularly enjoyable but does fill you up. 

This is really good.

This bar is an excellent meal replacement. I also use it as a snack, just cut in half and reseal  packaging. Helps me keep my calories down. A good taste and fills one up.

Buying again!

Great tasting bars, perfect in addition to the shakes for a meal replacement plan. 

Cereal bar

My go to bar, for breakfast, love them and filling too.


Tastes like a thick flapjack. Its ok if you are desperate for something to chew on after ongoing shakes. I tend to use half a bar at 5pm between shakes when craving for something with cup of tea. It stops me reaching for the biscuits

Not for me

Found these hard to bite and chew. They hurt my teeth.
