I’d recommend Our Path, which you can have prescribed on the NHS in some areas. Having tried WeighWatchers and SlimmingWorld this I’d definitely say this is better for me, as it’s all online. I’m 5 weeks in and have already lost nearly two stone.
It’s a low carb diet but I can assure you that you won’t get the carb cravings you tend to find with other ‘keto’ diets
I can give people a promotional code as well if anyone is interested
