Our genes can make us more likely to gain weight, but the choices we make about what we eat and how active we are also matter. Our body sends signals to our brain to tell us when we're hungry or full, and these signals can be influenced by hormones in our body. It's important to pay attention to these signals and make choices that are good for our health. Regular exercise is important for staying healthy, but it might not be the best way to lose weight. By understanding how our body works and making good choices, we can stay healthy and feel good.Giles Yeo is a scientist who studies how our bodies work when it comes to eating food.
