Well, here’s another good reason to stick to your weight loss resolution. According to a new study, it turns out that there’s a link between the size of your belly and the size of your brain. Researchers in the UK learned that obese people and those with large amounts of fat in the midsection also happened to have smaller brain volume compared to those who are an average weight. While the study published in the journal Neurology found that the two went hand in hand, it didn’t prove that being overweight caused brain shrinkage. Live Science points out that brain shrinkage can lead to problems such as “memory decline and dementia”.
