Very filling

I find these so rich that it lasts me a long time. Very filling also.

Sadly, not for me.

I've been on Optifast for 2 weeks now, and I love almost all of the products I've tried. I am a self confessed chocoholic and shares in certain chocolate company must have plummeted. So, I was hoping these would be everything and a little bit more. The smell was good and I was looking forward to trying the Chocolate Meal Bar. However, despite trying to enjoy, I just don't. For me, I find them not just chewy, but to the point I feel like chewing sawdust. I know others enjoy them and I'd encourage anyone to try them but the Berry Meal Bars are by far my favourite.

Yummy bars

I really enjoyed these bars. They are a bit chewy which helps me as I tend to finish food faster and it made me slow down a bit but they are very tasty!

Not great

Unfortunately probably the worst product… tastes like cardboard with no flavour.  This is one product I regret buying three boxes of as wil be wasted Please consider a wider selection of snacks 

amazing bars

I tried many chocolate bars but this one is really amazing, I like it the most. (BTW I did not try other OPTIFATS bars)

Filling , soft and enjoyable

It has a nice taste and chewy very filling. It would be nice if it has a bit less sugar but really nice to give you the feeling of eating a choc bar without too much gilt 

Chocolate meal bar

This meal bar is very filling and satisfying. A lovely way to get the chocolate fix I want without feeling guilty!

OPTIFAST Chocolate Bar. Chocolate.

Gorgeous and indulgent! This is nothing like all the replacement meal bars I've tried in the last 40 years. It's more like a fudge bar from Cornwall. Its density means it stays in your stomach longer too. Mmm.


I be honest there quite pleasant but made my jaw ache it would be better if they made you feel fuller for longer 

Chocolate Meal Bar

These are good if you need that chocolate fix. Thick and chewy which I like. Best eaten slowly with a big mug of hot coffee or tea . Very filling and satisfying.
