The Art and Science of Foods That Fill You Up

A big part of healthy eating is filling up on the right foods. The problem is that trying to avoid cravings can feel crazy sometimes. Some people eat lunch and feel hungry again an hour later. What’s up with that?

The Science Behind Feeling Full

The reason you feel full after eating something is all in your head, literally. As your stomach digests your meal, it sends signals to your brain telling you that you’re not hungry anymore. Your body takes time to break down food into nutrients, releasing hormones that help you feel full and content.

Even your emotions are involved. Have you ever noticed how happy and satisfied you are after eating a meal that you love? On the other hand, when you’re stressed or depressed, you probably feel hungrier than normal. This is all because of hormones.

The Reason Some Foods Make You Feel Full Longer Than Others

Why are some foods more filling than others? One reason is that they take longer to digest. The more time your stomach spends processing food, the less time it has to feel hungry. Here are a few things that can make any meal more filling:

  • Fiber: Foods that are high in fiber take longer for your body to digest. Fiber turns the things you eat into a kind of gel, slowing them down as they move through your intestines. Another benefit of fiber is that it balances your blood-sugar levels, basically telling your body that your energy levels are good so you don’t need to eat anything else.
  • Protein: When you eat protein, your body releases specific hormones responsible for feelings of fullness. High-protein foods are the best snacks for calming the munchies. Eggs have a lot of protein, and so do nuts and different types of fish.
  • Water: Getting enough water with meals is a great way to calm your appetite. Not only does water have zero calories, it contributes to fullness. Fruit that naturally has high water content is very filling, such as a slice of watermelon or some fresh pineapple.

Other foods help you stay full longer because they have a low energy density. In other words, they have a lot of volume but not very many calories. You feel satisfied without feeling guilty.

The Best Foods for Calming Hunger

The munchies can make cutting calories from your diet easier said than done. To have success with your weight loss goals, reach for these foods at meal time:

  • Soup: Cooked veggies and protein with plenty of water are the perfect recipe for a filling meal.
  • Greek yogurt: This healthy treat has a lot of protein and probiotics to calm hungry feelings.
  • Vegetables: Did you know that broccoli is 90% water? Leafy greens are packed with fiber, too. Carrots are another filling choice.
  • Fresh fruit: Apples, bananas and oranges have plenty of fiber and water, and they’re super-fast to grab on the go.
  • Potatoes: Boiled or baked potatoes are among the most filling foods on the planet. Scientists think they have a special protein that suppresses appetite.

My personal recommendation is to add a salad to everything (but skip the ranch dressing). If you’re making spaghetti for your kids, make some salad, too. That way you eat fewer calories but still feel satisfied. This helps calm nighttime snacking temptations a lot.
