As a bloke who has spent most of his adult life overweight to differing degrees, I joined WW 18 months ago and lost 3 stone fairly easily. Due to a job change with lots of travel, hotels and dinners, I've managed to put almost half of my weight loss back on and am really disappointed with myself.
Having read about this diet and spoken to so many people about how well it works, decided to give it a try.
I totally get where the OP is coming from and it isn't going to work for everyone, just like WW and SW doesn't either.
However, the maths behind this and any diet is very simple, if the amount of calories you consume exceeds the amount you burn, you won't lost weight. The reverse is also true so by creating a calorie deficit, you will lose weight.
Some of the terms used for this diet alarm me - a so called 'feasting day'. What's all that about?
I get the idea of normal eating between fasting but for anyone trying to lose weight, surely 'normal eating' is what has got us here in the first place?
I accept the body does odd things and you can lose weight when least expecting it but ultimately over a decent timespan, eating too many calories will lead to an increase in weight - I can vouch for that through personal experience.
I'm happy to try this for a month and see what happens, if the weight is shifting at a sensible rate- I've never been one of those who lost 4-5lbs each week- then I'll stick with it. But if like the OP's wife, it doesn't give the hoped for results, I'll first take a long hard look at myself and decide whether I've fooled myself with my eating or this diet simply isn't compatible with my aims.
Done properly, this is a calorie restricted diet working on the scientific finding that people do not overcompensate for the calorie deficit on fast days on subsequent feed days.
Everyone is overthinking this. Basically, eat less but eat enough, using the key mantra that when you are hungry, you can eat whatever the next day, as generally you don't.
This way of eating makes the whole thing more analogous to how people live, rather than trying to calorie restrict every day.
Once you relax, the cravings go away and it all gets easier. I can lose weight with SW or WW, I just can't keep it off. I'll be able to do this though as necessary.
