16 Snacks That Keep You Full (Without Spiking Blood Sugar)

If you find yourself hungry again an hour after snacking or feeling tired after a sugar crash, your snack might be missing one key ingredient: balance.

Snacking isn’t just about eating less. It’s about eating smarter so you stay full, energized, and steady between meals.

What Makes a Snack “Blood Sugar Friendly”?

The best snacks are made of 2 key parts:

  1. Protein or healthy fat to keep you full longer
  2. Fiber or slow carbs to help avoid blood sugar spikes

When you combine these, you slow digestion and give your body steady fuel. That’s what helps curb hunger and prevent energy crashes.

Try This Combo Method

To build a smart snack, just pair:

  • Protein or healthy fat: yogurt, nut butter, eggs, tuna, cheese, seeds, nuts, or hummus
    with
  • Fiber-rich or water-rich carbs: fruit, vegetables, whole grains

This combo fills you up without sending your blood sugar on a rollercoaster.
