Which hormone is blocking my weight loss?

Several hormones can affect weight loss including insulin (regulates blood sugar and fat storage), cortisol (stress hormone that promotes belly fat), thyroid hormones (control metabolism), leptin (signals fullness), and ghrelin (triggers hunger). Hormonal imbalances from poor sleep, chronic stress, insulin resistance, or thyroid issues can make weight loss harder. If you suspect hormonal problems, consult a doctor for proper testing and treatment rather than self-diagnosing.
