Don’t ever weigh yourself on January 2nd. To quote Yoda, “Only pain you will find”. Weight is a terrible measurement of health. What I mean is, don’t let the scale dictate how you should feel about yourself. You should go about how your clothes fit. If you want to get technical then go by body fat percentage. Buy yourself some fancy fat pinchers if you must know the details. Don’t go by BMI because you can be obese even if you are an elite athlete bodybuilding freak of nature.
I started a new way of eating a few years ago and I lost weight quickly at first but then the next year I lost no weight at all. Once you get comfortable with your clothes, you should shop for some new ones and donate the old ones. If you buy quality threads you can also sell them on eBay
