If you have been giving in to the food pushers in your life up until now, it’s very likely that the first time you set a boundary, they will be shocked and they might not respond very well. Don’t give up. The more often you stick to your boundaries, the more they will know that no means no. You may choose to offer some kind of explanation, but you don’t owe it to them. Remember that YOU are the one who ultimately has to deal with the consequences of overeating, not them, so you are the one with the authority to make the decision about what you eat or don’t eat.
