If your mom is pear- or apple-shaped, are you destined to inherit her body shape? The answer is, well, complicated. Research in this field is still emerging, but what we know is that bone structure, frame size and muscle mass are inherited. Studies also show that up to 80 percent of body fat is regulated by your DNA.
Apple-shaped people, those who carry weight around their middle, are more likely to get that from their parents than their pear- or boy-shaped counterparts.
But here's the good news: While you may be predisposed to having a larger or rounder body, it is in your control to eat healthy and exercise. You may even be able to slightly change the shape of your body through weight training, running, and other activities. Also, take pride in the fact that younger generations are reaping the benefits of Title IX, which increased women's sports teams. We lead more active lifestyles than our mothers, and our daughters may be more active than us!
The bottom line: Genes dictate how your body evolves, but adopting a healthy lifestyle and building muscle can minimize a widening waistline.
