You could turn to the vending machine for a bag of stale chips, but as you already know there are better options out there. Better options that will help you actually feel full, supply your body with some nutrients, and even taste good going down. Do they require a bit more pre-planning than selecting "B6" on a vending machine? Sure. But once you've worked them into your daily routine, healthy snacking for weight loss or maintenance becomes a very easy thing.
Avocados and Tomatoes
The fatty acids and fiber found in avocados keep you full for longer. In fact, avocados eaters weighed less, had smaller waists, and lower body mass indexes, according to one study. Pair avocados with tomatoes, which are low in calorie but full of lycopene, an antioxidant that supports healthy blood pressure. Do this in guacamole with whole-wheat chips and you've got it.
