I have to agree, low carb worked for me. If I’m eating complex carbs and sugar I can eat everything in sight and not feel full. A whole pack of biscuits, huge bar of chocolate whatever, and I want more. I’m not a binger, but I could eat a large quantity of something snd it would not make me feel full or not for long. And if it’s in th house it plays on my mind till I eat it.
However when I’m low carbing, which is nearly all the time for the last decade, I’ve just fallen off the wagon three or four times in the last decade or so, after about two weeks all cravings go, it can be in the house and I’ve no desire to eat it, I don’t even think about it, and my appetite decreases, so I eat till I’m full and stop. When I’m eating lots of carbs and sugar that doesn’t happen. I can keep going.
I also have a lot more energy on low carb, when eating sugar and lots of carbs I’m sluggish. When I’m low carb and burning fat I’ve much more energy,
I’d recommend it, try it for two weeks, have a look at the low carb boot camp threads.
Clearly the ocd is something to address and you may have an eating disorder, which also needs to be addressed, but in the meantime give this a go if it appeals.
