Being healthier, fitter, and so on will have positive and maybe unexpected ripple effects. However, even as a slimmer person you’ll still have a bad day in the office, moments of self-doubt, or times when you feel undervalued.
Many people feel let down when they become slimmer and then find that being slim doesn’t solve all their problems in one go. They then revert to eating poorly again. Don’t fall into this trap.
You have lots of different needs which need to be fulfilled in life. Being slimmer, healthier, and fitter is just one of them.
