Weight gain isn’t like a cold that goes away with a quick fix; it’s more about changing how you live, which takes time and effort. Since habits and daily choices are so ingrained, making lasting changes usually requires a longer commitment. So, while a 3-month program can kickstart your journey, a 6-month (or longer) program gives you a better chance at not just losing weight but keeping it off. In essence, the longer the program, the more durable the results, because it’s about building and solidifying new habits for life.
