Many people make the mistake of reverting back to their old habits once they hit their goal weight. Not surprisingly, you're more likely to gain the weight back this way. Luckily Kim, who lost 100 pounds, knew not to make that mistake.

"Once you hit your goal, the journey does not end there, and to maintain the weight you lost, you will need to continue what you were doing to lose that weight in the first place," Kim told POPSUGAR.
