You might think obesity is a modern problem, but new research suggests it was around even during the Ice Age. We know this thanks to small statues called Venus figurines, which show women with larger body sizes. Surprising, right? Especially since it was a tough time for food. Scientists are wondering how this happened. They've come up with a special idea called the eco-life-course hypothesis. It combines changes in food with how our bodies are affected by our parents' health.

During the Ice Age, people had strong bodies and needed a lot of protein. But as time passed, they started eating more plants, which have less protein. This led to a problem: people ate more to get enough protein. This is called the protein leverage hypothesis. Another thing to consider is how mothers' weight affects their kids' chances of being overweight. Putting it all together, scientists think that during the Ice Age, lowered protein in diets made people eat more, and this problem got worse over generations.

This obesity issue might have happened because of a trade-off. Bodies had to choose between growing tall or getting fat. Some people with certain genes may have faced this more. Scientists hope this new way of looking at things will help other experts study prehistoric obesity better and understand what those old statues tell us about our history.
