 This is the biggest factor that determines whether or not what you're doing is sustainable and that is to fix your why. Now, if the why you're trying to make these changes is because you don't like the way you look, you think you're fat, you're not good and adequate, whatever, then this is going to be very difficult to sustain because you can motivate yourself to make big changes through shame and self-hate, but you really rob yourself of the joy that could be there from feeling like this is a voluntary growth pursuit. It's very different when you do this because you're like, well, I'm overweight, but I want to take care of myself when out feels very different. The other way at some point starts to feel overbearing and tyrannical and almost always leads to rebellion. This is where you go off your diet in such a big way because you want to quote unquote, enjoy your life. So you have to start with the why, and this is a conscious decision. I'm going to the gym because I want to take care of myself. I'm going to eat this way because I deserve to be healthy. If you do it in this fashion, then it feels good. Exercise is self-care. It's not punishment and diet is nourishment. It is not restrictive.
