If you have ever wondered why Snickers advertisements are so popular, then here’s the answer: they are popular, because they are relatable and true. Look for yourself:

The inference was made while experimenting for hypoglycemia (low blood sugar) being a factor for depression, anxiety, and stress. “We found evidence that a change in glucose level can have a lasting effect on mood”, tells Professor Francesco Leri from University of Guelph in Ontario, Canada.

The conclusions were reached after testing the mood changes and emotional behavior of hypoglycemia-induced rats. The rats really were affected in terms of their behavior, after they were kept low on glucose levels.

Likewise, humans are not themselves when they are hungry and the amount of glucose in their blood decreases. This explains the famous tagline of snickers: “You’re not you when you’re hungry”.

According to another researcher, poor eating and the resultant mood change can get humans stuck in a vicious cycle of poor eating –behavioral changes –not wanting to eat –further hunger. Poor eating also gives way to stress, anxiety, and depression in people.
