There are a couple of things you’re going to want to take into account at this point. Firstly never be afraid to try a few before you settle on one. You shouldn’t bet partaking in anything you’re finding unpleasant or ridiculously difficult. A challenge is fine and welcome but you don’t want weight loss to take up all your time and energy, you want it simple and easy to follow.
Secondly, read up on your desired schemes. There are always online reviews on these things and if you’re going to commit yourself to something you owe it to yourself know as much about that something as is physically possible. If it’s amazing or doesn’t work, you’ll find a review online which will attest to that.
Thirdly and most importantly, don’t doubt the tried and tested methods. Things like weight watchers or slimming world might seem a little outdated but having a regular group to meet with and discuss any progress or failings is a powerful thing. Having people going through the same thing, motivating you and urging you forward is great and a huge amount of people lose a considerable amount of weight with schemes like those every single year! They’ve been around for a very long time and nothing lasts that long if it doesn’t work at least for some people!
