Calorie Density: Eat More, Lose Weight and Get Healthy

The magic of calorie density in a whole food plant-based (WFPB) diet lies in its ability to let me eat more while still losing weight and staying healthy. By prioritizing foods that are naturally low in calorie density, like fruits, vegetables, whole grains and beans, I can enjoy larger portions that fill me up without excessive calorie intake. This approach not only supports weight loss by allowing me to consume satisfying amounts of food but also ensures I’m eating nutrient-dense meals packed with essential vitamins, minerals, and fiber. The high water and fiber content in these foods helps keep me full and reduces overall calorie consumption, making weight management effortless. There is the bonus that a WFPB diet improved my overall health and reduces the risk of developing chronic diseases that run in my family.

What is Calorie Density?

Calorie density refers to the number of calories contained in a specific weight or volume of food, typically measured in calories per pound. It provides a way to understand how concentrated the calories are in different foods. Foods with low calorie density, such as vegetables, fruits, whole grains and starches, have fewer calories per pound, meaning you can eat larger portions without consuming excessive calories. Conversely, high calorie density foods, like nuts, cheese, sugary snacks and oil, pack more calories into a smaller volume. By focusing on foods with lower calorie density, you can enjoy more food by weight or volume while managing calorie intake, which can be particularly useful for weight management and overall health.

Volumetrics: Eat More and Weigh Less

Barbara Rolls' research was instrumental in defining this concept of calorie density and its impact on satiety and weight management. She emphasizes the role of food volume in influencing how full we feel in her Volumetrics books. Rolls’ studies demonstrated that foods with low calorie density like fruits, vegetables, and soups, can be highly effective for managing appetite and reducing overall calorie intake. By consuming larger portions of these low-calorie-density foods, individuals can achieve greater satiety and satisfaction while maintaining a calorie deficit necessary for weight loss. Rolls' research highlights how focusing on the volume of food rather than just calorie content can lead to healthier eating patterns and more sustainable weight management, making her work a cornerstone in the field of nutritional science.

Most Satisfying Foods to Feel Full

The best foods for achieving satiety while keeping calorie intake low include those high in water and fiber, which help maintain a sense of fullness. Vegetables such as leafy greens, broccoli, and bell peppers are excellent due to their high-water content and fiber, contributing to a feeling of satiety without many calories. Fruits like apples, oranges, and berries are also effective, as their natural sugars are balanced by fiber and water. Legumes, such as beans, lentils, and chickpeas, provide both protein and fiber, making them particularly filling. Whole grains like oatmeal and pasta are beneficial for sustaining energy and curbing hunger.

Most interestingly, research on the satiety index has ranked boiled potatoes as the highest among foods tested for their ability to promote fullness. This is due to their high-water content and the way they expand in the stomach, which helps keep hunger at bay and supports weight management while providing essential nutrients. Potatoes don’t make you fat, they make you skinny! The trick is to not load them up with butter, cheese and sour cream.

Healthiest Diet on the Planet

Eating a diet focused on lower calorie density foods is widely regarded as one of the healthiest approaches due to its numerous benefits for overall well-being and aligns with the best dietary patterns observed in the longest-lived people around the world - the Blue Zones. 

By emphasizing whole, nutrient-dense foods, there are multiple health advantages of a WFPB diet:

• High Nutrients: Provides essential vitamins and minerals critical for optimal body function.
• Antioxidants: Rich in antioxidants from fruits and vegetables that combat oxidative stress and inflammation.
• High Fiber: Supports digestive health, aids in weight management, and reduces the risk of chronic diseases and constipation. 
• Digestive Health: Promotes a healthy gut microbiome and regular bowel movements.
• Processed Foods: Avoids unhealthy fats, sugars, and additives commonly found in processed foods.
• High Energy: Fuels the body with complex carbohydrates and high-quality nutrients for sustained energy.
• Better Immune Function: Enhances immune system performance with a diverse range of nutrients and phytochemicals.
• Weight Management: Helps manage appetite and maintain a healthy weight due to high volume and low calories. A healthy weight reduces the risk of developing diabetes.
• Reduced Chronic Disease Risk: Lower risk of heart disease, diabetes, and certain cancers by focusing on whole, unprocessed foods.

No Pain and No Gain

The beauty of caloric density and a WFPB diet is you can eat an abundance of food, feel full and lose (or maintain) your weight. It really is that simple and I am surprised at how many people don’t give it a try or know about this dietary approach.  I guess it’s hard for people to shift their dietary pattern to avoid oil and butter, meat and eggs, and milk and cheese if that’s the way they’ve been eating their whole life.  If you want to get started on this approach, you can still eat those higher calorie foods, but they need to be limited on your plate. Think of them as adding flavour and treat them like a condiment.  Here’s some tricks to getting started:

1. Load Up on Vegetables: Start your meal with a salad or fill half your plate with vegetables at every meal. Choose non-starchy vegetables like leafy greens, bell peppers, and broccoli. They are low in calories but high in volume, which helps you feel full.
2. Choose High-Water Foods: Incorporate foods with high water content, such as cucumbers, tomatoes, and melons. Water-rich foods add bulk to your meals without adding many calories. 
3. Include Soups and Stews: Start your meals with a vegetable broth-based soup or stew. These dishes are often low in calorie density and can help you consume fewer calories overall by filling you up before the main course. 
4. Choose Whole Grains and Starches: Choose whole grains like oats, brown rice, and quinoa over refined grains. Or fill up on potatoes, sweet potatoes, and corn. Whole grains and starches have more fiber and a lower calorie density, which aids in satiety. 
5. Snack on Fruits: Replace high-calorie snacks with fresh fruit. Apples, oranges, and berries are not only low in calorie density but also provide essential nutrients and fiber. 
6. Introduce Legumes: Incorporate beans, lentils, and chickpeas into your meals. They are high in protein and fiber, making them filling and low in calorie density. 
7. Cook with Low-Calorie Ingredients: Use herbs, spices, and vinegar to flavor your dishes instead of high-calorie sauces and dressings. This can enhance the taste of your meals without adding extra calories. 
8. Increase Meal Volume: Add extra vegetables or fruits to your meals to increase their volume without significantly increasing the calorie content. Try adding extra veggies to a stir-fry or “hiding” veggies in a tomato sauce.

So many people fear “carbs” nowadays, but they really have it backwards. I eat about 80% carbs and got back down to my high school weight after battling the last 10 pounds for years.  I love eating large portions and can really pile it in. I still have treats and junk now and again but sticking to a WFPB diet 90% of the time enables me to maintain my weight and stay healthy.  Eating this way has kept away diabetes, high cholesterol, and high blood pressure. Give it a try and see how great you feel! Don’t fear the potato!!
