When I was lifting weights I went from 170lbs to 210, and back to 170. Doing that isn’t technically hard, and maintaining is even easier. But I had to think about it _all_ the time. Maybe it’s because I’m older now, but I just don’t want to spend that much effort thinking about food.

lifting weight isn't efficient for weight loss.

Without calorie deficit, you'll not lose much weight by lifting alone.
