Could be water weight, slower metabolism as the body may thinking starvation mode or if your exercising it could be muscle gain. You didn’t give a timeline but if you just started be patient.

Body weight tends to fluctuate by a few pounds. It depends on the foods you are eating, and hormones can also have a major effect on how much water your body retains (especially in women). Also, it is possible to gain muscle at the same time as you lose fat.

It's probably a fluctuation in water weight like blissedbunny said. Weight loss is never linear. If you keep up the hard work and stay in a caloric deficit it'll pay off eventually. It has to.

Same here, seems to be water weight

Maybe you need to workout as well?

Water retention .

One pound isn't bad, you have to consider clothing, building muscle, water retention and fecal matter as well.
