1. Kale crisps: Reaching for a bag of crisps? Grab some kale crisps instead! Whether fried or baked, these dark green leaves are perfect for when you’re craving something salty and crunchy. They are low in fat and calories, yet high in fiber and antioxidants. Make them at home by tossing kale leaves with olive oil and salt, then baking them until crisp. You can also add your own tasty low fat vegan dips for extra flavor. 
2. Dark chocolate: While it should still only be enjoyed as an occasional treat, dark chocolate is one of the best alternatives for sweets if you crave something rich and decadent. It’s high in vitamins, minerals and antioxidants that benefit your health. It also contains less sugar and fat than milk chocolate. Choose dark chocolate with at least 70% cocoa solids for the most benefits. 
3. Fruit and yogurt ice popsicles: These treats are low in fat and sugar, high in protein and calcium and rich in antioxidants and vitamins. They are also easy to make at home with your favorite fruits and yogurt. To make your own, try chopping some strawberries into small pieces, then mix with some plain yoghurt. Spoon the mixture into ice popsicle ice trays and freeze for at least 4 hours.  
4. Fresh Fruit: When it comes to healthy alternatives to junk food, fresh fruit is a no brainer. It not only contains a whole host of essential nutrients, fiber and antioxidants, it’s also a great way to satisfy your sweet tooth naturally. For something a bit different, try sprinkling cinnamon on some apple slices or filling a hollowed-out watermelon with a fruit salad, turning a simple snack into a delicious, healthy taste sensation. 
5.Unsalted popcorn: The popcorn you get at the movies is packed full of added butter, sugar and salt. We’re talking about air-popped, unsalted popcorn which is low in fat and high in fiber, containing vitamins and minerals such as iron, zinc and magnesium. This low-calorie snack is delicious and filling but just remember the minute you start cooking it in butter or adding sugar, popcorn can quickly turn it into an unhealthy choice.
