3 Worst People for Your Diet

Your Boyfriend

• Your guy can chow down on wings and pound back beer without gaining weight. Men have a higher amount of muscle mass and lower body fat percent than women.

Your Grandmother 

• Your grandma always wants to feed you. "She sees it as a welcoming gesture and you see it as diet sabotage," says Mangieri. But instead of completely giving into nana's attempts to put meat on your bones, set some limits.

Your Friends

• Make an effort to choose from the menu’s healthier options and monitor your portions. If your friends are pressuring you to make unhealthy choices, filling your plate up and packing half of it in a container is an easy solution.
