When you can catch low motivation when it first starts, you’ll be able to return to following your diet plan quickly and with a lot less grumbling. This will help you change your eating habits for the better over time and promote lasting long-term results.
Motivation is a challenge you must prepare and expect for. Just get right back on if you fall off the bandwagon for a day or two. If motivation peters out completely and you return to former bad habits for a week or longer, it only becomes a set-back.
