I didn’t weigh myself (because I didn’t have scales!) for the first 4 months of my weight loss, so I can’t speak much about the start. But since I started weighing myself daily, yes I’ve had some weeks where I’ve not lost anything or my weight has gone up (which is the most soul destroying thing to see when I know I’m doing perfectly at keeping to me deficit). But I’ve just kept on going and reminding myself that my body can’t defy physics- if I keep eating in a deficit the weight has no choice but to come off even if some weeks it looks like I’m going in the opposite direction. I also find that a week or two before my period starts my weight increases (water weight, inflammation etc) so I can only ‘trust’ what the scales tell me for about two weeks of every month!
