Not the best stuff really Col, more style over substance, plus always read they can make you go to the loo a fair bit.
If you trust the process, eat right (have a little count on the calories, I'd not obsess, but sometimes if you tot them up a little, you can see you are eating more than you think... sometimes not though, just a thought!)
If you want to stoke the fire, you can always do your own 'fat burner' type thing, just use some chilli and caffeine! If you like your food spicey, it is a good way to get the engine burning. You could do what I do at times, tuna/pineapple/fresh red chilli and some black pepper corn. Tastes nice (I put in some apple cider vinegar) and gets things going!
Fat is stubborn, but if you keep at it, slowly but surely, it will go as long as you are exercising enough and eating right. A basic calorie deficit really.
Working for me right now on the food plan I have been on. I would merge my thread into this one, but it would then mix up your post I think. Will do it at some stage.
