If you're on a mission to cut out calories, the FoodTweeks app is a handy one that will help you as well as other. With the app, users get access to a number of tweaks to popular food items that will help to cut down on calorie consumption. For example, the app suggests swapping your regular Big Mag order for a McDouble.
Each time you make a note of a "Tweek," the app rewards you by making a donation to a local food bank that is representative of the calories that you cut out from your meal or snack. The donated amount can be doubled by sharing your Tweeks with friends on social media. As well as being a great way to learn about healthier options on the go, the app is almost like a game that challenges you to do more for the purposes of social good.
