Why hormones often make weight loss (or plateaus) harder
Hormones control hunger, fullness & metabolism
Hormones like Leptin (satiety/fullness hormone), Ghrelin (hunger hormone), insulin, thyroid hormones, and stress hormones all play a role in telling your body when to eat, how much, and how fast to burn energy.
When your hormones are “off,” the system misfires
For example: if you have high insulin (or insulin resistance), your body may store more fat and burn less.
Hormonal signals adapt when you restrict calories or over‑exercise Doing a very strict “eat less, exercise more” regime can raise stress hormones like Cortisol. When cortisol stays elevated, your body may respond by preserving fat often around the abdomen because it “thinks” you’re starving. This also disrupts s*x hormones (like Estrogen and Testosterone), which further complicates metabolism, muscle mass and fat storage.
As body fat drops, regulatory signals change
When fat mass decreases, leptin levels fall, which signals to the brain that energy stores are low. That can trigger increased hunger and a slower metabolic rate making sustained weight loss and further fat loss harder.
Hormonal changes across life stages matter (e.g. perimenopause / menopause) As hormone levels change with age, the strategy that used to work may no longer be effective.
Bottom line: Hormones aren’t just a “background” factor they’re central to how our bodies store fat, feel hungry/full, burn calories, and respond to diet and exercise. Sometimes, even with “perfect” diet & exercise, hormonal imbalance or mis‑regulation can stall or reverse expected weight change.
*What we can do* practical steps to support healthy hormone‑linked weight regulation
Avoid extreme calorie restriction or over‑exercising
Instead of harsh dieting, aim for reasonable, balanced eating. Very low calorie diets or long heavy workouts can raise cortisol, disturb metabolism, and make the body hold onto weight.
Prioritize nutrient-rich whole foods (not ultra‑processed)
Whole foods, balanced macros (healthy fats, sufficient protein, fiber, complex carbs) help support stable insulin, leptin and other hormone levels.
Focus on strength training / resistance + smart activity, not just cardio
Strength / resistance training helps maintain or build muscle, which supports a healthy metabolism and may counter hormonal shifts that reduce metabolic rate.
Prioritise good sleep and stress management
Poor or insufficient sleep disrupts hormones that regulate hunger and fullness (like leptin and ghrelin), while chronic stress raises cortisol both of which can sabotage weight‑loss efforts.
Be kind hormones make it more complicated than “just calories in/calories out”
If you’re doing “all the right things” and still stuck, hormonal balance might need support (e.g. via lifestyle adjustments, medical check‑ups). It’s not a moral failure it’s biology.
