Weight Loss Resistance Protocol

Frustrating reality: Some people can't lose weight despite "eating less and moving more." Blame the victim mentality is wrong - hormonal and metabolic factors often prevent weight loss. Thyroid is #1 culprit: Hypothyroidism slows metabolism dramatically. Even subclinical (TSH 3-4, "normal range") impairs weight loss. Many providers accept TSH <4.5, but optimal for weight loss is 0.5-2.0 with free T3 in upper third. Reverse T3: T4 converts to reverse T3 (inactive) instead of T3 (active) during stress, calorie restriction, inflammation - blocks thyroid receptors, slows metabolism. Many chronic dieters have elevated RT3. Insulin: Fat-storing hormone. If insulin elevated (insulin resistance), body can't burn fat even in calorie deficit. Must address insulin first. Leptin: Satiety hormone made by fat cells. Should signal brain "enough fat stored, speed up metabolism, reduce hunger." But leptin resistance (like insulin resistance) - brain doesn't hear signal despite high leptin. Result: Constant hunger, slow metabolism, can't lose weight. Caused by inflammation, high triglycerides, chronic obesity. Cortisol: Chronic stress/elevated cortisol drives belly fat, insulin resistance, evening eating. Many stressed chronic dieters have cortisol dysregulation. Estrogen dominance: High estrogen (relative to progesterone) causes water retention, fat storage especially lower body. Sex hormones: Low testosterone (men and women) means less muscle, slower metabolism. Metabolic adaptation: Body adapts to calorie restriction by slowing metabolism (survival mechanism). Chronic dieters have slowed metabolism - need reverse diet to restore. Inflammation: Elevated CRP impairs metabolism. Gut dysbiosis contributes. Toxins: Stored in fat cells, body may resist fat loss to avoid releasing toxins into circulation. Medications: Many psych meds, beta-blockers, insulin cause weight gain - often overlooked. Sleep: Leptin/ghrelin dysregulation with poor sleep drives hunger and prevents fat loss. Weight loss resistance is multi-factorial hormonal issue, not willpower. Test don't guess. Address underlying obstacles before more diet/exercise. Many patients lose weight easily once thyroid optimized, insulin addressed, stress managed.
