Someone recently asked me about how I stuck to eating so healthy and maintain my weight. She was saying that she has trouble staying with healthy foods. After a while the food gets boring to her. This was someone who did a wellness challenge... as you know I participated in two challenges last year. One thing I learned from the challenge is it's a lifestyle change, not a temporary diet. The only way to lose weight and keep it off is to incorporate the habits from the challenge into your daily routine, even after the challenge ends.
So many people will go back to the foods that got them overweight in the first place. I think one reason that it's hard for some people to keep a healthy diet is that they didn't find food that they liked enough to stick with. If you don't like the food you're eating, eventually you will give up and go back to your old style of eating. It's important to incorporate a large variety of healthy foods and be creative. If you hear of a food that has a lot of health benefits, try it and see if you like it.
