Ever noticed how the same 10-15 pounds keep returning no matter how disciplined your diet? You're not alone. Our brains actively fight weight loss by treating dieting as a form of starvation. The hypothalamus functions as a weight "thermostat," defending a target weight range spanning about 10-15 pounds. Within this range, weight is relatively easy to modify, but staying below the brain's target is extraordinarily difficult. This defended range can increase over time through puberty, pregnancy, aging, or staying above your current weight range too long. Critically, this process isn't reversible. Even years of keeping weight below the defended range doesn't reset the brain's target lower-it continues trying to push weight back up. Research consistently shows most dieters regain lost weight. After a year, the average dieter has lost 6% of starting weight, but then steadily regains it, typically reversing all progress within five years. Only about 15% maintain significant weight loss for three years or more. Despite popular beliefs, no particular diet produces better long-term results than others. The problem isn't that we're dieting incorrectly-it's that dieting itself doesn't work. In fact, dieting often leads to weight gain, not loss. Within four years, two in five dieters end up heavier than before they started.
