I was lurking and saw this thread, just had to reply, hope you don't mind...
Cohens is NOT like Sureslim, other than that you have a blood test at the beginning. There the similarity pretty much ends.
With Cohens you will be given a specific food prescription. It will tell you what you can eat and when. Not exact times, but rules for how to eat, for example you can't mix proteins, so you must have 5 hours between protein meals.
I lost my weight on the Cohens programme, and it took me just under a year to lose 88kg. If you have a look at the 'slimmer of the year' competition page, you can see my before and after photos on the last page. I'm #10, Larysa J. Also on the SOTY site, in the bottom left corner.
The programme is NOT difficult. Actually it's probably the easiest around, being that there is NO decisions to be made. You're told exactly what you can have. No variations, no guessing, no judging, nothing.
I've seen MANY different people's programmes, and I've never seen two even remotely similar. They are DEFINATELY not the same. I know Sure slim's are based on your 'blood type' as in, if you're A+ you get diet #2, etc. Cohens has nothing to do with your blood TYPE, it's got to do with the hormone, insulin and seratonin etc levels in your blood. Dr Cohen examines these and writes your programme individually.
While on the programme I ate six meals a day,
Breakfast (for me) was yoghurt, but I could have had egg and veg or other choices,
Morning tea was an apple and a full salada bikkie.
Lunch was usually Chicken and salad (but there were other choices, sometimes I had prawns and salad, or tuna/salad, etc).
Afternoon tea was another apple and half a salada (two squares).
Dinner was chicken or beef and veg or salad.
Supper was another piece of fruit (usually an apple, but I love apple, or nectarine when they were in season) and another salada.
I found it amazingly easy to stick to, I just told myself that everything else was 'out of season'. I can have it again now that I'm finished. You're usually hungry/detoxing for the first usually 3 or 4 days, but after that, nup, not until the very end, when you're body's finished running on the stored fat (and goodness knows I had quite a bit of that!).
The biggest difference between this programme and any other is that it 'resets' your metabolism. When you reach your goal, and hence reach a metabolic equilibrium, you are given a 'refeeding programme' which re-introduces the foods you haven't been able to eat while on the programme. It reintroduces them in a controlled manner, again with rules. It's a little complicated, but hey, if I can do it anyone can.
This end programme is the only one of it's kind in the weight loss industry. It means your body is retrained to eat normal foods.
You need to be careful forever, as you would in any other programme, but, it gives you a MUCH better chance of not putting the weight back on.
I hope this has answered some of your questions. I'll wander back to see if there are others, or if you like you can visit the cohens forum
Nice to meet you all!
