Have you ever finished a meal and felt uncomfortably full? There's a Japanese phrase for avoiding this — hara hachi bu. It means "80% of the stomach," because you should only eat until you're 80% full. Hara hachi bu isn't about dieting or giving up the foods you love — it's about being mindful and appreciating what you eat. The goal is to feel satisfied, not stuffed, so you can enjoy your food without feeling heavy or uncomfortable afterward. This not only helps you enjoy your meals more, but over time, this small change can make a big difference in your health, too. Eating a little less allows your body to digest food more easily. Some research suggests that stopping at 80% full may also lower the risk of serious health problems like heart disease and certain cancers. And it's not just good for your body — hara hachi bu can support your mental health as well. Being mindful of what you eat can help you notice when you're eating from stress, boredom or habit instead of actually feeling hungry. So how do you know when you're 80% full? One way is to slow down. It usually takes 15 to 20 minutes for your stomach to send the "full" signal to your brain, so if you eat too fast, you may miss it. But by eating slowly and taking breaks between bites, it becomes easier to stop at the right time. You can also eat less by staying away from distractions while eating. Try turning off the TV, putting your phone away and focusing on enjoying your meal. Studies show that about 70% of people use digital devices while eating, and this habit is linked to eating more calories and fewer fruits and vegetables. So the next time you eat, try slowing down, paying attention, and listening to what your body really needs. You might find that feeling 80% full is just right!
