1. I’m not sure about using the techniques I teach for feeling like you don’t want to do something. This is very much about the “addictive desire” of wanting to do things you regret later on. My only advice about overcoming resistance to establishing exercise is to start small, but the way I resolved that problem was to get a dog.
2. I do think it’s tough to eat less without having identified any downside to the overeating behaviour. So the first thing is to ask yourself why you might want to eat fewer vegetables and what benefit you might gain as a result of eating less of them. In order to get more clarity for yourself about this, you could try eating fewer vegetables to see if it suits you. If there’s no benefit to you, return to eating more of them, as you were before.
Let me know if any of this isn’t clear.
