Your Diet is Too Restrictive
If you eat nothing but grilled chicken and veggies, that's not sustainable. You'll feel so miserably deprived that you'll crave everything you don't allow yourself to eat, which will backfire and you'll end up binging. Of course, that will just make you feel guilty, and you'll go back to restricting. Stop the vicious cycle with the 80/20 approach to eating: eating healthy, whole foods most of the time (about 80 percent of the time), and 20 percent indulgence foods you love.
