Begin with breakfast for a bunch. Offer a variety of whole-grain cold cereals, yogurts, fresh fruit, whole-grain bagels and English muffins, whole-grain toaster waffles and pancakes, nut butters, fruit spreads, fat-free milk and 100% fruit juices. Brew a pot of coffee and set out a selection of teas and everyone's good to go.

Let them eat lunch. Guests will appreciate a fridge full of sandwich fixings to assemble on their own schedule. Offer lean fillings such as sliced turkey, chicken, ham or roast beef plus reduced-fat versions of cheeses such as Cheddar, Swiss, mozzarella and havarti. Stock a selection of whole-grain breads and pita pockets, and toppings such as prewashed lettuce, roasted red peppers, flavored mustards and light mayo. Don't forget peanut butter and jelly for the kids!

Keep super-nutritious snacks for a crowd. When it's munch time, guests will thank you for stocking up on containers of dips such as hummus, salsa and tzatziki (a Greek yogurt and cucumber dip), a tray of cut-up veggies from the produce department, and baked whole-grain pita and tortilla chips. Keep a bowl of ready-to-grab washed peaches, plums, nectarines, grapes or cherries right on the counter.

Do dinner together. Gather guests for fast and healthy dinners. Set out a spread of rotisserie chicken, pasta salad and roasted vegetables. Or grill lean hamburgers, turkey burgers or veggie burgers to serve on whole-grain buns with corn on the cob, sweet potato chips and fruit salad. Really pressed for time? Order a veggie-topped pizza and serve with a big mixed vegetable salad from the supermarket salad bar.

Refresh with a selection of beverages. Keep plenty of cool water on hand, as well as 100% fruit juices, fat-free milk, unsweetened ice tea and diet soft drinks.

Offer a sweet ending to remember. For an evening treat, lay out a make-your-own-sundae bar with different flavors of light ice cream or frozen yogurt, toppings such as sliced bananas and strawberries, chocolate and caramel syrup, chopped walnuts, and a can of light whipped cream.

Keep guests moving. Give guests directions to nearby walking trails or walking-friendly sites such as museums or zoos. Keep a jump rope, Frisbee or badminton set on hand for kids. Arrange for guests to use the local pool or get them a pass to your gym or health club.
