When you live a busy lifestyle, snacks can be useful when hunger hits and you don't have time to prepare a meal.

However, many snack foods available today are high in refined carbs and sugar, which can leave you feeling unsatisfied and craving more food.

The key is to make sure your snacks are nutritious and contain protein.

Protein promotes fullness because it signals the release of appetite-suppressing hormones, slows digestion and stabilizes blood sugar levels.

Here are the high-protein snacks that are healthy and portable, so you can enjoy them even when you're on the go. Each one explained inside.
