Weight plateaus are the way our bodies adjust to a lower weight. This involves hormonal changes and the resetting of what our bodies see as our usual weight after it’s been much higher for a long time. Just keep doing what you’re doing and when your body is ready, you’ll start loosing again.

Ive been doing IF about 15 or so months. I’ve lost 100lbs, and a currently in my third or so, month long plateau. Focus on not back sliding/gaining, and trust the process. Do your best. The weight will start to go down if you stick to a window, and don’t overeat too too much.
