I’m on Bodyslims at the moment and it’s really working for me, when nothing else has.
It’s a 10 week online course, and it sorts out diet, exercise, and most importantly - your head.
You get a calorie limit at the start, which you have to stick to. You are meant to take a walk every day, and make it part of your routine. There is a 1-2 hour weekly seminar online that you listen every Wednesday, which is weigh-in day. And every day there is a short 1-minute morning video and and evening video check-in, to encourage you and keep you in the right path. There is a motivational song and motto every day too, and a positive hypnotherapy type track to listen to at night. All this is within an app that you get access to for the 10 weeks.
It is immersive, but that is why it works. It sounds cult-like, but it isn’t, you just have to commit to do as Ger (the coach) instructs for the 10 weeks, and the weight falls off. It’s not uncommon for people to lose 15-25lb.
I highly recommend it, the next course starts just after Easter, it runs 3x a year.
