Not losing weight on 16:8 intermittent fasting? Before you fast longer, check five things that could explain why your weight and waist measurements have stopped changing.

In this video, we examine why a fasting weight loss plateau can happen—and why a shorter eating window does not automatically mean more body fat loss. From water retention to food intake, daily movement, and sleep, these five checks help you decide what to adjust.

16:8 intermittent fasting means fasting for 16 hours and eating within an 8-hour window. It can help you eat fewer calories, but changing when you eat does not always change how much you eat. Your scale also measures more than fat, so an unchanged body weight does not tell the whole story.

You’ll learn:
• How water weight can hide changes in body fat.
• Why skipping breakfast may not create a calorie deficit.
• Why your energy needs can decrease after weight loss.
• How moving less can affect your progress.
• Why too little sleep can make hunger and food choices harder to manage.

We look at human research on time-restricted eating, calorie intake, resistance training, and sleep to help you understand the difference between burning fat during a fast and losing body fat over time.
