Take a look at Warning 3 in the first post here https://thefastdiet.co.uk/forums/topic/warnings-to-newbies/ – plateauing for a while is very common.

In the FAQs there is also an answer to the question “What do I do if I’m not losing weight?”

Hope this helps.

Many other factors can be responsible for stalling of weight loss even while maintaining a strict calorie deficit. But the most likely possibility of all is not really being in a calorie deficit. This is caused due to miscalculations, approximations, inconsistency and underestimation of calories while eyeballing portions. Other than these, increased stress levels, water retention and metabolic adaptations could be causing temporary halt in your weight loss journey. What I’d suggest to resolve this is reworking your numbers, tracking your foods more accurately, working towards better managing stress and utilizing diet breaks to not completely fry your metabolism. Hope you get through this plateau mate!

Even if you consume the same number of calories that made you lose weight, your slower metabolism will slow down your weight loss. You reach a plateau when the number of calories you consume and expend is equal. You need to either improve your physical activity level or reduce the number of calories you consume in order to lose more weight.

With a low-calorie intake like 800 calories a day, your body might be holding onto water or even slowing down its metabolism as a protective measure. I’ve found that mixing things up with https://fitnflexed.com can really help kickstart things again. Basically, strength training helps preserve muscle mass, which is crucial when you’re on a low-calorie diet, and cardio can help burn extra calories and boost your metabolism.
