This Video Explains All Our Chocolate Cupcake Problems

ASAP Science breaks down the science of overeating, and what fat and sugar have to do with it

Accidentally eating an entire pizza in college may have been the norm, but honestly, half a pie on sad nights just isn't healthy. So here's to explaining why we overeat, despite the fact that we know we're full.

Turns out, our body's internal regulating system relies on the hormones ghrelin and leptin. The first triggers our desire to eat; the second stops it.

The problem is, however, that our bodies are wired to take in as much fatty and sugary foods as possible, since those types of energy-makers were rare to find in the past. Nowadays, it's all over the place, and the more sugar and fat you take in, the less effect leptin will have. So the trick? Surround yourself with healthy foods, and avoid too many chocolate cupcakes. Baking, it turns out, can be a dangerous habit.

Watch the science lesson below and figure out the science behind overeating in less than two minutes.
