You're surrounded by food pushers.

You know the type: your aunt who looks so insulted if you turn down a second serving. Your coworker who begs you to try whatever baked good she brought in that day. Your friend who wants to order dessert but insists you need to split it with her. These people are called food pushers, and obvious as it might seem, they can and often do cause you to eat things even when you actually don't want them by playing to your guilt. No matter the situation, your best response is to say simply "no thank you, I'm not hungry," says Shank. While people can implore you to "just treat yourself" if you tell them you're trying to eat healthy, "no one can argue if you're hungry or not," she says.
