A weight loss plateau may be explained by muscle gain, undigested food, and fluctuations in body water. If the scale doesn't budge, you might still be losing fat.
Lummus says that when your body goes into starvation mode, your metabolism slows to a crawl, burning calories as slowly as possible to conserve its energy stores. This is why people who cut their calories too much may reach a plateau and stop losing weight.
It simply takes time. Another common reason why people report not losing weight despite reducing their calories is that they don't give it enough time. Our bodies will do their utmost to hold on to our fat reserves and you often have to be in a calorie deficit for a while before you will see any meaningful weight loss.
You're eating too much during your eating window.
“If you end up consuming the same number of calories (or more) during your eating windows as before you started intermittent fasting, then you won't lose weight.”
Undereating may cause weight gain for some people, but even if it doesn't, it's important not to eat so little that it adversely affects your health. From constipation to immune dysfunction, not eating enough can lead to a host of health issues.

In terms of how your body looks, “it usually takes 4 weeks for your friends to notice weight loss, and 6–8 weeks for you to notice,” says Ramsey Bergeron, a certified personal trainer. “Your friends who don't see you every day are much more likely to see a change than someone you're around all the time,” he adds.
Most people who have difficulty losing weight are simply eating too many calories. An important factor in weight loss is how many calories you're eating versus how many calories you're burning. It may seem easy, but if you're not tracking your calories each day, you may be consuming more than you think.
You can't lose weight on 1200 calories a day because you're no longer in a calorie deficit. Your body has adapted to what it's been doing and plateaued.

If you drastically slash calories and are eating a very low-calorie diet (Think: less than 1,000 calories for women and less than 1,200 calories for men), “starvation mode” can actually be starvation. Starvation from chronic undereating can be counterproductive to weight loss and dangerous to your health.
