Even on summer’s hottest days, keep your cool with the following tip from TOPS Club, Inc. (Take Off Pounds Sensibly), the nonprofit weightloss support organization. Stay hydrated. It’s easy to become so preoccupied with summertime fun that you forget to drink enough water. Keep your water bottle handy or cool off with hydrating fruits, like watermelon. Freeze fresh fruit, like blackberries or blueberries, can also be used to chill your iced tea or flavour your water.
