From what I can see, the food on diet chef is all available in good supermarkets
Waitrose sell the nakd fruit bars and I think they're £2.99 for 6..quite expensive, also the nairns biscuits, and the packs of granola. The regular sized pack of granola costs £4.99 ..sorry don't know the weight of the pack offhand, but it looks as though they send individual packs and I don't know where they're sold. The main meals and the soups are definitely from the look what we've found range, which are a range of microwavable stews, soups and casseroles, that don't need refrigeration. Think they sell at about £3 per pack.
I would think that the diet chef company has struck up a deal with the manufacturers involved and they supply the goods in plain packaging and diet chef TM will stick their own labels on. I think if you were to buy the items individually from the supermarket, it would work out quite dear, so possibly money wise, the deal's quite good value for money.

The only thing about this diet I'd say wasn't so good, is that it's obviously portioned out for the needs of one person, which is fine if you are a single person living alone, but if you have a family to feed as well, I'd imagine that it could be quite a lot of hassle. Also, £156 pounds out of your grocery allowance is an awful lot just to spend on food for yourself, and of course you still have to buy all the fruit, veg and milk you will need to compliment the diet. Probably a good fix for someone who needs to lose a little weight quickly for an upcoming event say, but as a serious long term eating plan, I have my doubts.
I think the food is probably good quality for what it is, but I really don't think there's any "ready meal" that's going to be as good as something cooked from scratch from fresh ingredients..unless you're the worst cook in the world of course lol!
