Re lots to lose cheddar, I think slow and steady is best. It can get very frustrating but in the long run is the best way and fits in with the general theory of the book.
I've lost three stones doing a version of this - no UPF and no alcohol. Then stalled having, as I now know, reached a set point. I am hoping that reducing carbs a bit further, and eliminating sugar, wheat and veg oil as far as reasonably possible, will get things moving in the right direction again.
I have a stone and a half to go to target, two to ideal, so realistically am looking at least at early next year I think.
Exercise is good, yes. We now know it's more complex than calories in and out, but that aside, I love feeling toned and strong, and that's good for how I feel about myself. It also gets all the feel good hormones flowing- so I am less tempted to fall off the wagon into emotional eating. Plus it's important for general health reasons- I'm going through the menopause. Le sigh.
Finally slow weight loss is easier on the pocket when buying new things to wear. I have walking trousers in four different sizes in my cupboard from past weight loss regimes.
I hope to be able to be confident enough to donate the larger sizes soon.
