2. Cooler is one of the best inventions ever. Seriously, if you plan to spend a day at the beach or an outdoor excursion, you can just pack a cooler with lunch and snacks and not think about the food for the rest of the day. Lets be honest, beach food is the worst. You usually get stuffed with fries and hot dogs, and you are hungry after a few hours. Instead, pack healthy stuff like fruit salads, trail mixes, low fat cheese, baby carrots… You can enjoy eating these foods all day long without fearing those extra pounds.
