Struggling to get that perfect summer body? Blame Genetics.

Scientists have found that a set of neurons is responsible for the unpleasant feelings associated with hunger, as they explain in this article. The neurons do not drive an animal to eat, but rather teach an animal to respond to sensory cues that signal the presence of food. If you're finding it difficult to stick to a weight-loss diet this is why! Scientists say you can likely point the finger at AGRP neurons -- hunger-sensitive cells in your brain. New experiments show these neurons are responsible for the unpleasant feelings of hunger that make snacking irresistible. The negative emotions associated with hunger can make it hard to maintain a diet and lose weight, and these neurons help explain that struggle.

I certainly know the struggle of trying to get ready for that summer beach body, and I found this article to be really interesting. I'm interested to follow the study and see what further developments they make and if their is a way to interfere with the neuron to aid in weight loss.
