Hi Wobbly 71 - I'm doing SS+, and have done since day 1. I love my evening meal, and love being able to choose some real food when I do the family shop. The portions are 125g of white fish, chicken or turkey plus 2 tablespoons of green vegetables (asparagus, spinach, cabbage, kale, etc) or green salad.
I have always eaten more than the 2 tbs of veg/salad and stayed in ketosis throughout, although I am 5ft 10 with largish frame. I am not recommending this, just stating what I do. I personally do not consider this cheating, but do acknoweldge it is off plan. That said I am pleased with my weight losses - 24lbs first 4 weeks and 4lbs and 3lbs for weeks 5 & 6.
In summary - do I like SS+ - without a doubt! it works, I'm not hungry and I love my meal. It has also gone a long way to retrain the way I eat and what I like to eat. Cannot see myself returning to red meat in abundance again, and as I dont miss carbs now I just wont bother with them again!
Sorry for the long reply - but as you can tell SS+ comes highly recommended!!! Best wishes with your decision. Traceyxx
