No weight loss

Along with patience (because you might just be rushing it) you might not be eating enough. Your body literally might not have enough fuel to build the muscle and lose the fat. Without enough calories you are most likely not going to get anywhere.

Do you eat back some of the calories you burned while working out? Not the ones a machine says but ones that maybe you get from a fitness watch, HR monitor. Anything?

When I was actually succeeding at my weight loss (i gained a lot this last year) I increased my calories from 1200, to 1800 to accommodate for the increased work I was doing. it helped me tone up, but lose fat as well. I looked significantly better. The less work i do during the day, the less I ate but I found this to be a really good place, somewhere between 1500-1800 FOR ME. Not sure your age, how much you are trying to lose, but it does come down to that as well.

Good luck!

It's hard, but you just have to be patient. Weight loss isn't linear and instead tends to occur in fits and starts. There are a lot of reasons the scale isn't moving. You could be gaining muscle. You could be retaining water. Your body could be undergoing recomposition. You kind of just have to keep the faith and trust the process. It sounds like you're working out really hard, and not eating a lot. When you work out a lot, your muscles tend to retain a lot of water. Calorie restriction also stresses the body and sometimes you just need to give your body a break. Oddly enough, I've had good results by just easing off a little when the scale stalls. You could mix things up a bit by eating at maintenance for a couple days and skip a workout. It might make the scale move.

I also would suggest measuring your success by tracking things other than the scale. The scale is finicky and not always the best indicator of how things are going. Track your measurements - you may be shrinking even though the scale isn't moving. I have experienced plateaus where I didn't lose any weight for a month, but I lost a pants size during that time. You can also track improvements to your fitness. Can you lift more? Run faster? Walk farther? If so, it's still a win.
