Some hosts and hostesses have an unspoken belief that giving or receiving food, drink, or drugs is the same as giving or receiving love, that every social event must involve food, drink, and drugs and that refusing an offer of food, drink, or drugs is somehow insulting to them. Accept a drink if offered, always asking for a low-calorie beverage. Accept food in portions fitting your needs. Refuse any type of drugs. Eat the allowed amount and leave the rest.
Hostesses are sometimes more insulted by a refusal to eat than by food left on a plate.
This is a time to entertain by role model and example. Use strategies from social events here, too. Always have plenty of fresh water available. Offer well-balanced, appealing, attractively presented meals, appetizing yet nutritious and low in calories and fat. Keep the focus of the entertainment social by trying to keep the discussion on the benefits of a healthy lifestyle.
