Repeated weight loss failures train your brain to believe dieting won't work for you. Once that story sticks, your brain protects you from disappointment by avoiding effort rather than actively sabotaging it.

If you've ever lost weight and then put it all back on again, maybe more than once, it makes complete sense that your belief has taken a knock. Because every time that happens, your brain stores it as evidence, and over time it builds a story: "This doesn't work. I can't do this." And here's the problem: once your brain believes that story, it starts behaving as if it's true. Not to sabotage you, but to protect you, to stop you feeling that disappointment yet again.
