There are actually certain foods you can eat as a man that will virtually guarantee you develop gynecomastia–also known as the dreaded “man boobs.” If you want to keep your chest nice and flat and sexy, avoid these foods like the plague. If you’re concerned about man boobs, here’s what you DON’T want to eat!

Gynecomastia can be caused by a variety of things, including excess weight, the side effects of certain medications, and hormonal imbalances. One of the top culprits for causing hormonal imbalances in today’s food supply is the antibiotics and hormone supplements given to livestock in modern factory farms. These substances can end up in the meat and dairy products produced by the animals that were given them. If you eat meat and dairy from these animals, those hormones can get passed on to you, and can ultimately cause the hormonal imbalances that can lead to man boobs. Opting for organically produced meat and dairy can help you avoid this problem.

While you’re at it, you may also want to avoid heating up any foods in plastic containers. There are certain chemicals in today’s plastic containers that can disrupt the hormonal balances in your body, and they sometimes leach out when heated. Glass or ceramic cookware is much better for heating up foods, and can keep gynecomastia at bay.

Aside from hormonal imbalances, extremely fatty, sugary foods can cause excess fat deposits to form on the chest, so play it safe and opt for low-fat versions of your favorite high-fat foods (and be sure the sugar content is also low). You can reduce cravings and suppress your appetite by eating lots of whole grain foods, as well, since the fiber in the whole grains will fill you up. With just a few simple diet adjustments, you can avoid gynecomastia, get rid of man boobs, and keep the svelte, sexy chest you (and the women!) love.
