Pretty soon you're going to be able to blame your mom for giving you more than you may have originally thought.
Recent reports claim that your body shape is determined primarily by your genes. Researchers identified three fat-predicting genes: T-box 15, glypican 4, and homeo box A5 (... the names sound more like the names of rappers than the names of genes if you ask me). This could explain why you may feel like a pear when your co-worker (who eats worse than you) is more like a banana.
Why should we care about this news? Well the newly found genes may finally give researchers clues for obesity drug development in the future. But for now, if you feel like your own genes may be working against you, eat a healthy and balanced diet and start exercising.
