380-550 calories. Not into super intense workouts that get you all sweaty or require a wardrobe change? Walking is one of the easiest and most beneficial activities you can regularly engage in to maintain or lose weight (in conjunction with a healthy diet). Squeeze it in as much as possible throughout the day, and if possible, go for a brisk walk after dinner, to ensure proper digestion and get your metabolism going before you become immobile for the rest of the day.
