how many habits do you need to change to get to your goal weight?

How many habits do you need to change in order to live at your goal weight? I'm going to assume that the number you are thinking is a lot higher than the number I'm about to say. People struggle to lose weight, they need to change everything, and then they start to feel overwhelmed and they can't sustain it. So the magic number of habits I've seen that need to be transformed in order to get you very, very close, if not all the way to your goal weight is three. The first two are your worst eating habits, where you're consuming the most calories, and the third one is the habit that makes you the most tired in life. Change these three habits and it gets much easier to live at your goal weight.
