Calories And Plant-Based Diets: Friend Or Foe?

A plant-based diet has been proven to be an effective way to lose weight without counting calories. A plant-based diet focuses on whole foods, which are natural foods that are not heavily processed. This includes fruits, vegetables, whole grains, legumes, nuts, and seeds.

Plant-based diets are associated with reduced excess body fat and lower insulin resistance. They are also linked to a reduced risk of developing chronic diseases such as type 2 diabetes, heart disease, and certain types of cancer.

However, it is important to note that a plant-based diet does not restrict meat and dairy completely. It focuses on proportionally choosing more foods from plant sources.

Calorie density: the number of calories per unit volume for a given amount of food

Calorie density is a measure of the number of calories in a given volume or weight of food. It is also referred to as energy density and is usually measured as calories per 3.5 ounces (100 grams) of food. Foods with a high calorie density have a high number of calories per volume of food, while those with a low calorie density have fewer calories per volume of food.

Calorie density is an important factor in weight management. High-calorie, low-nutrient foods typically have a high calorie density, while nutrient-rich, lower-calorie options have a lower calorie density. Eating a diet that includes more low-calorie-density foods can help with weight loss as these foods tend to be rich in fibre and water, making people feel full and reducing their daily calorie intake.

For example, a vegetable with 30 calories per 100 grams has a low calorie density, while chocolate with 550 calories per 100 grams has a very high calorie density. Similarly, lean proteins like chicken and turkey have a low calorie density, while fattier meats have a moderate to high density.

When it comes to plant-based diets, it is important to note that while these diets are often associated with weight loss, calorie intake still matters. Even on a plant-based diet, it is possible to overeat and gain weight if portion sizes and total calories are not taken into account.

Plant-based diets can be high in fibre, which makes people feel full and fuels a healthy gut microbiome

A plant-based diet can be a great way to increase your fibre intake, which has a range of health benefits. Fibre is a type of carbohydrate found only in plants that cannot be digested by the body. There are two types of fibre: soluble and insoluble. Soluble fibre absorbs water and leaves you feeling full, while insoluble fibre remains intact as it passes through the body, aiding digestion.

Plant-based diets can be high in fibre, which has several health benefits. Firstly, fibre helps you feel full. Soluble fibre absorbs water and leaves you with a feeling of fullness, which can help with weight loss and weight maintenance. This is because high-fibre foods tend to be lower in calories, meaning you can eat a larger volume of food without exceeding your calorie needs.

Fibre also fuels a healthy gut microbiome. Insoluble fibre, also known as fermentable fibre, serves as food for the bacteria in the gut. Consuming high amounts of insoluble fibre is crucial for a healthy gut microbiome, which is responsible for numerous health processes in the body, including boosting immunity and helping to balance blood sugar.

In addition to these benefits, fibre can also help lower blood sugar, fight constipation, reduce cholesterol, and lower the risk of certain cancers.

The daily recommended fibre intake is 25-38 grams, depending on age and gender. However, most Americans only consume around 15 grams of fibre per day, which is less than half of the recommended amount.

So, how can you increase your fibre intake? Here are some tips:

• Incorporate vegetables into every meal.
• Add chia seeds and flax seeds to smoothies.
• Use cocoa powder, which has 2 grams of fibre per tablespoon.
• Eat less heavily processed food and more whole foods.
• Switch from white rice to brown rice.
• Choose bread with nuts, seeds, and whole grains.
• Include lentils, peas, or beans in your meals.

Plant-based diets are not automatically healthy: they can be high in calories and lead to weight gain

While a plant-based diet is a great way to improve your health, boost energy levels, and prevent chronic diseases, it is not a magic solution. Calories still matter, and it is possible to gain weight on a plant-based diet if you are not careful.

Calories In, Calories Out

The idea that a calorie is a calorie is a common trope in the food industry, which suggests that overeating carrots would have the same effect on weight gain as overeating soda. However, this comparison fails to consider the different satiety levels and nutritional profiles of these foods. For example, it would take over two and a half hours to eat ten carrots (240 calories), whereas a bottle of Coke (also 240 calories) could be consumed in under a minute. Moreover, you might feel full after just a few carrots, whereas you could easily drink the whole bottle of Coke without feeling satisfied.

Calorie Density

Whole plant-based foods tend to be low in calories and high in fibre, which helps you feel full without exceeding your calorie needs. However, some plant-based foods are more calorie-dense than others. Nuts, seeds, avocados, tofu, and plant-based milks are more calorie-dense and should be consumed in moderation to avoid weight gain. Oils are a good example of a highly calorie-dense food. Just one tablespoon of oil adds over a hundred calories to a dish.

Portion Sizes

Even when eating healthy, whole plant-based foods, portion sizes still matter. One person following a plant-based diet shared their experience of gaining weight because they were eating too much, even though they were consuming only healthy, whole foods. They had to reduce their portion sizes and pay attention to total calories to lose weight.

Weight Loss Strategies

To lose weight on a plant-based diet, focus on eating whole, unprocessed, plant-based foods that are low in calorie density and high in fibre. Eat until you are comfortably satiated, rather than restricting your portions. You can also try preloading your meals with low-calorie-density foods, such as salads or apples, to reduce your overall calorie intake. Finally, be mindful of your total calorie intake and make sure it is appropriate for your activity level and weight goals.

Plant-based diets can be more affordable than omnivorous diets

A plant-based diet can be more affordable than an omnivorous diet. Research has shown that a plant-based diet can cut grocery bills by $750 a year per person. This is because whole and minimally processed plant-based foods are some of the most affordable foods available.

The Cost of a Plant-Based Diet

A plant-based diet primarily consists of vegetables, fruits, grains, legumes, nuts, and seeds. These foods are rich in dietary fiber, vitamins, minerals, and phytonutrients, offering various health benefits, including anti-inflammatory and antioxidant effects.

The Cost of an Omnivorous Diet

An omnivorous diet includes animal products like meat and dairy, as well as plant-based foods. This diet can provide complete nutrition, offering essential proteins, fats, vitamins, and minerals. However, the inclusion of animal products can increase the cost of an omnivorous diet compared to a plant-based diet.

Saving Money on Groceries

When stocking your kitchen with plant-based staples such as brown rice, potatoes, and dried beans, you can create nutritious and satisfying meals for just a few dollars. For example, a budget-friendly one-week vegan meal plan can be created for as little as $7 a day.

The Benefits of a Plant-Based Diet

In addition to being more affordable, a plant-based diet offers several other benefits. These include:

• Easy weight management: People who eat a plant-based diet tend to be leaner, and the diet makes it easy to lose weight and keep it off without counting calories.
• Disease prevention: Plant-based diets can prevent, halt, and in some cases, reverse chronic diseases such as heart disease, type 2 diabetes, and certain types of cancer.
• A lighter environmental footprint: Plant-based diets place much less stress on the environment.

Plant-based diets can be more environmentally sustainable than omnivorous diets

Plant-based diets are more environmentally sustainable than omnivorous diets. This is because they use fewer natural resources and are less taxing on the environment. The global population explosion and increase in wealth have increased the demand for animal-based foods, but current worldwide food consumption practices are unsustainable. Natural non-renewable resources are becoming scarce, and environmental degradation is rapidly increasing.

Environmental Impact

Shifting to more plant-based diets can lead to reductions in greenhouse gas emissions, land use, and freshwater use. Vegan diets show the highest reduction potential, followed by vegetarian and flexitarian diets. This is because animal-based foods contribute the most to greenhouse gas emissions, even though they account for a smaller percentage of total energy. Meat products, for example, were responsible for about 43% of total emissions.

Economic Impact

Transitioning to more plant-based diets can result in small to moderate changes in daily food expenditure. The average cost per day of the current Swedish diet is about SEK 82, while vegan diets based on plant-based alternatives or whole foods are estimated to be 10-20% more expensive. However, shifting towards whole foods diets can decrease estimated daily food expenditure by 4-17%.

Nutritional Impact

Plant-based diets can provide nutritional benefits, such as higher fibre, folate, and lower saturated fat content. However, vitamin B12, vitamin D, and selenium intake may decrease, and sodium intake may increase. Plant-based diets also meet or exceed protein and zinc recommendations.
