Scale stalls after a drop are almost always water and body adjustment, not the medication losing effect. Clothes fitting or measurements might still be changing even when the scale isn't moving. Usually breaks through in a week or two.
The 35-lb loss from 285 with the feeling-off experience is worth tracking - at that scale, body composition shifts can create a disconnect between the mirror and expectations, especially when torso fat changes before facial appearance catches up. Scale calibration matters here: home versus medical office scales vary by hydration timing, clothing, and time of day. Pre-appointment weigh-ins are the more controlled comparison, but neither reading is wrong.
Rapid loss creates real systemic effects. On bone density the window that matters is now - resistance training during loss does more than starting after.
Inflammation and water fluctuations make early weeks noisy. The 35 lbs is real - fat and water release in waves, not together. Measurements over time tell the story better.
