Your skinny best friend seems to eat twice as much as you but you're still overweight. Why? For decades, experts thought they had the answer - too many calories and not enough exercise. But the latest scientific research is turning those assumptions on their head. Differences in our individual biology - our genetics, hormones, or psychology - all play a crucial role. Now, five volunteers are going on diets tailored to their bodies and brains. They're just like you - normal people who spend their lives going up and down in weight. Combining rock-solid science with engaging personal stories, this experiment will revolutionise how we think about diet. Think long-term weight loss is impossible? Think again.
Join Michelle and Teo under the sea as they make crafty sea creatures, go on a trash and treasure hunt and experiment with floating eggs in water. Through the windows, we take a closer look at the ocean.
