Metabolism slows — but not as fast as people think.
Recent research shows resting metabolism stays fairly stable through middle age before declining. The bigger drivers of weight change are usually hormonal shifts and lifestyle load.
What people call 'slow metabolism' is usually a system effect.
Sleep loss, perimenopausal hormone shifts, certain medications, and chronic stress all push the system toward weight gain, not metabolism alone.
A clinical review separates signal from noise.
Your provider can order the right labs and look at the full picture — thyroid, hormones, inflammation, medications — to identify the actual driver.
