THE SCIENCE OF SATIETY
Finding ways to stay full and satisfied between meals is essential for maintaining energy levels, reducing overeating, and supporting overall health. Figuring out what feels satisfying to you can feel like a game-changer, especially if you might be coming from a place of not eating enough and/or making meals as small as possible. The magic that I feel when clients describe breakfast as being satisfying or nourishing, and keeping them full until lunch…this is when I know that they are beginning to understand the beauty of finding and pairing filling foods with fullness cues. **chef’s kiss**
Understanding the science behind satiety — the feeling or sensation of fullness after eating — can help you make smarter food choices (for your body) that keep hunger at bay. By focusing on foods that promote satiety, you can enjoy meals that not only nourish your body but also keep you satisfied for longer.
SATIETY DEFINED
Satiety is a signal to your body that it’s time to stop eating. It’s influenced by several factors, including the volume of food, the macronutrient composition, and the way certain foods interact with hormones that regulate hunger (like ghrelin and leptin).
Foods that enhance satiety typically have certain characteristics — they are high in protein, fiber, and fats, or have a high water content. These foods help slow down digestion, keep blood sugar levels stable, and provide a steady release of energy, all of which contribute to feeling full for longer periods.
FOODS THAT PROMOTE SATIETY
PROTEIN-RICH FOODS
Protein is one of the most satiating macronutrients. It not only helps build and repair tissues but also slows down digestion, which helps you feel full longer, and often reduces the feeling of “I need to snack in order to make it to the next meal.” Satiety from protein-rich foods at each meal can significantly reduce the likelihood of overeating later in the day.
Lean meats: chicken, turkey, and lean cuts of beef are excellent sources of protein. They provide a high level of satiety and can be incorporated into a variety of meals.
Fish: fatty fish like salmon and tuna are not only rich in protein but also provide healthy fats that further enhance satiety.
Eggs: eggs are a versatile protein source that can be enjoyed at any meal. Prepare them your favorite way for breakfast (over-easy, scrambled, sunny side up), or scramble into rice and veggies to elevate a stir-fry!
Batch prepping protein is a great way to ensure that you have something on hand to add to (or boost!) a meal that is in need of a protein component.
FIBER-RICH FOODS
Fiber is another key player in promoting satiety. Foods high in fiber add bulk to your meals, slow down the digestive process, and help stabilize blood sugar levels. There are two types of fiber—soluble and insoluble—and both contribute to a feeling of fullness in their own way.
Fruits and vegetables: fiber-rich fruits like apples, pears, and berries, along with vegetables such as broccoli, Brussels sprouts, potatoes, and carrots, can help keep you full between meals.
Whole grains: oats, quinoa, and rice (brown more than white, in this case) are great sources of fiber. They can be used as a base for meals or added to dishes for extra bulk.
Legumes: beans, lentils, and chickpeas are not only high in fiber but also rich in protein, making them a powerful duo for satiety.
HEALTHY FATS
Incorporating healthy fats into your diet is another way to increase satiety. Fats take longer to digest than carbohydrates, helping you stay full longer. They also play a role in hormone regulation, including the hormones that control hunger.
Avocados: avocados are packed with heart-healthy monounsaturated fats and fiber, making them an excellent addition to meals for satiety.
Nuts and seeds: almonds, walnuts, chia seeds, and flaxseeds are high in healthy fats and protein, making them great for snacking or adding to meals.
Olive oil: olive oil can enhance the satiety of your meals when used in dressings, cooking, or drizzled over vegetables – just one of many ways to season meals.
“HIGH VOLUME” FOODS
Foods that are high in volume but low in calories can help you feel full without consuming a large number of calories – I most often talk about these foods with clients who are in a calorie deficit, but their qualities are the same no matter the goals that you are eating and working toward. These foods are typically rich in water and fiber, adding bulk to your diet.
Fruits and vegetables, especially those with a higher water content: watermelon, oranges, grapefruit, cucumbers, and zucchini are all fairly high in water content. Add to that vegetables like spinach, kale, and other leafy greens that are low in calories but high in volume and nutrients, making them a great choice for adding bulk to meals.
Soups and broths: starting a meal with a broth-based soup can help fill you up with fewer calories – my favorite is bone broth, which has an additional few grams of protein.
TLDR: TIPS TO STAY FULL AND SATISFIED
Start your day with protein: breakfast is a critical meal for setting the tone for the day. Including protein in your morning meal can help stay satiated until lunchtime.
Include fiber in every meal: whether through whole grains, legumes, or fruits and vegetables, make sure each meal includes a good source of fiber to enhance satiety. My rule of thumb (and visual cue) to include fiber is to make sure there is always some color on my plate!
Don’t skip healthy fats: incorporate healthy fats into your meals. To note: be mindful of portion sizes, as fats are calorie-dense.
Stay hydrated: sometimes thirst is mistaken for hunger. Drinking water throughout the day can help you stay hydrated, and equally as important, to optimize physical performance, support brain and muscle health, and keep energy stable.
Understanding the science of satiety is a powerful tool for making informed food choices that support your health and well-being. And: the key to a satisfying diet is not just what you eat but also how you eat it — mindfully, with attention to your body’s natural signals.
