I would say get checked by doctor/Endocrinologist and do the relevant bloodwork (Esp. Insulin levels, thyroid, etc). A family member is overweight and nothing changed even with diet changes and regular exercise. It took a long time to find out the root issues (especially Insulin resistance). Once we got the root cause, they put the member on Wegovy (weekly Injection) and started a low carb diet and exercise. It is amazing to see the effect Wegovy has taken with the member's weight loss. Couldn't recommend it enough now for people with genuine weight loss issues.
