The biggest loser chocolate crunch bars are amazing- although I love the S&S chocolate praline bars (which have been out of stock for ages) the biggest loser one is probably my favourite. Similar texture to a Truffa i.e. chewy-ish but taste is better! They are much bigger and are 200 calories so quite a bit more than S&S bars. There is also a biggest loser mint fudge bar which isn't as nice, but still very edible, they are big too and 206 cals. They are both expensive though at £2.29 a bar.
