Carbs And Plant-Based Diets: How Many Per Day?

Carbohydrates are an essential part of a healthy diet, but in recent years they have been demonised as causing weight gain. This has led to many people restricting their intake of nutrient-dense foods. There is no scientific evidence that eating carbohydrates leads to weight gain, and research shows that weight loss is possible regardless of diet type. Carbohydrates are especially important on a plant-based diet, as they provide a variety of essential vitamins and minerals. So, how many carbs should you eat per day on a plant-based diet?

How Many Carbs Per Day on a Plant-Based Diet

The different types of carbs: starches, fibres, and sugars

Carbohydrates are essential food nutrients that your body turns into glucose (blood sugar) to give you energy. There are three main types of carbohydrates: starches, fibres, and sugars.

Starches

Starches are complex carbohydrates, which are made of lots of simple sugars strung together. They are found primarily in whole grains and root vegetables. Starches include bread, pasta, and cereal, as well as certain vegetables like potatoes, peas, and corn. Starches are complex carbohydrates that give your body vitamins and minerals (micronutrients). It takes your body longer to break down complex carbohydrates, so blood sugar levels remain stable, and you feel full for longer.

Fibres

Fibres are also complex carbohydrates. Your body cannot break down most fibres, so eating foods with fibre can help you feel full and make you less likely to overeat. Fibre is found in most plants in varying quantities. It is recommended that adults consume at least 25-30 grams of fibre per day. Good sources of dietary fibre include beans, legumes, fruits, vegetables, whole grains, nuts, and seeds.

Sugars

Sugars are simple carbohydrates found naturally in multiple foods, including fruits, vegetables, and dairy. They are quickly broken down by the body, leading to a quick rise and drop in blood sugar levels. There are two types of sugars: naturally occurring sugars, like those found in milk and fresh fruits, and added sugars, like those found in sweets, canned fruit, juice, and soda.

The wrong carbs can lead to weight gain

Carbohydrates are an essential part of a healthy diet and can be found in many plant-based foods. However, not all carbs are created equal, and consuming the wrong types of carbs can lead to weight gain.

Types of Carbohydrates

Carbohydrates fall into three main categories: fiber, starches, and sugar. Fiber is found in most plants, while starches are primarily found in whole grains and root vegetables. Sugar is a simple carbohydrate found naturally in fruits, vegetables, and dairy.

The Problem with Refined Carbs

Refined carbohydrates, such as processed white bread, cake, and sugary drinks, have been stripped of their fiber and nutritional value during the refinement process. This means that they are quickly digested and absorbed by the body, leading to spikes in blood sugar levels and increased hunger. As a result, people who consume a lot of refined carbs tend to eat more throughout the day, which can contribute to weight gain.

In addition, refined carbs are often referred to as "empty-calorie" foods because they provide very little nutritional value. They are low in vitamins, minerals, phytochemicals, and fiber, which are essential for a healthy diet.

The Benefits of Complex Carbs

On the other hand, complex carbohydrates, such as whole grains, legumes, fruits, and vegetables, are loaded with fiber, vitamins, minerals, and phytochemicals. They take longer to digest, keeping you feeling full and satisfied for longer. This can help with weight management by reducing cravings and preventing overeating.

The Bottom Line

When it comes to carbohydrates and weight gain, it's important to focus on the quality and quantity of carbs consumed. While refined carbs can lead to weight gain, complex carbs are an essential part of a healthy diet and can even aid in weight loss. It's all about choosing the right types of carbs and maintaining a balanced diet.

Carbs are not more fattening than protein

Carbohydrates are one of the three main macronutrients that make up all food. The other two are protein and fat. Carbohydrates are further split into three groups: sugars, starch, and dietary fibre. Sugars are short-chain compounds found in fruits like apples, while starch is a longer chain of sugar compounds found in foods like bread, pasta, grains, and potatoes. Dietary fibre is also a polysaccharide, but unlike the other two, it cannot be digested by the gut.

Carbohydrates have been demonised as causing weight gain, but this is a myth. There is no science-based reason to believe that eating carbohydrates leads to weight gain. In fact, research shows that weight loss is possible regardless of the type of diet chosen (low-fat or low-carb).

Low-carb diets can be beneficial for some people, but they are not inherently more effective for weight loss than other types of diets. The idea that carbohydrates are fattening stems from the carbohydrate-insulin hypothesis of obesity, which states that insulin stimulation directly causes weight gain. However, this hypothesis has been proven incorrect in multiple controlled feeding studies. These studies show that when calories and protein intake are kept the same, there is no difference in weight loss between people on a low-carb and high-carb diet.

Instead, weight manipulation comes down to calorie control, not insulin control. It is also important to note that unnecessarily restricting carbohydrates can have unintended health consequences if proper precautions are not taken to ensure that nutrients found in carbohydrate sources are replaced in the diet. For example, one study found an association between low-carbohydrate diets during pregnancy and neural tube defects due to inadequate intake of folic acid, which is found in carbohydrate-rich fortified foods.

Furthermore, carbohydrates are the body's main source of energy and provide numerous health benefits. They are broken down by the digestive system into glucose (sugar) before being absorbed into the bloodstream and used as energy by the body. Fibre, a type of carbohydrate, is vital for general health as it may help reduce the risk of diseases such as bowel cancer, heart disease, and type 2 diabetes. It also promotes digestive health and may help manage appetite.

When it comes to weight loss, it is important to focus on overall calorie intake and nutrient density, rather than solely focusing on carbohydrate intake. Carbohydrates, when consumed in moderation and as part of a balanced diet, are not more fattening than protein.

A low-carb diet may not be the best for your health

Carbohydrates are one of the three nutrients that contribute calories to the diet, the other two being fat and protein. Carbs are the body's main source of energy. Carbohydrates can be divided into “simple” (sugars) and “complex” (starches and fibres). Simple carbs, like jam and honey, are broken down quickly by the body, causing a faster rise in blood sugar levels. Complex carbs, such as oatmeal, have more fibre, so are digested more slowly and don't raise blood sugar levels as much. This keeps you full for longer and keeps blood sugar more stable.

There has been a lot of hype around low-carb diets, with many people questioning whether carbohydrates are inherently "bad" and should be limited in the diet. While low-carb diets can be beneficial for weight loss and heart health, there are several reasons why a low-carb diet may not be the best for your health.

Firstly, there is no scientific evidence that eating carbohydrates leads to weight gain. In fact, research shows that weight loss is possible regardless of the type of diet chosen (low-fat or low-carb). Unnecessarily restricting carbohydrates can have negative consequences if proper precautions aren't taken to ensure that nutrients found in plant-based carbohydrate sources are replaced in the diet. For example, one study found an association between low-carbohydrate diets during pregnancy and neural tube defects due to inadequate intake of folic acid from fortified foods that are higher in carbohydrates.

Secondly, not all plant-based carbohydrate sources are equal in terms of nutrient density. While some are highly processed, others are minimally processed, and these differences can result in significant nutrient variations while also influencing calorie and nutrient density. Minimally processed plant-based sources of carbohydrates, such as whole fruits and vegetables, whole grains, beans, and legumes, are rich in essential vitamins, minerals, fibre, and phytochemicals. On the other hand, highly processed plant-based carbohydrate foods like refined grains, fried foods, and foods with added sugars are less nutritious and can lead to an increased intake of less healthy nutrients like added sugars and saturated fat.

Thirdly, low-carb diets may not be suitable for everyone. Studies suggest that while a low-carb diet may help some people lose weight, it may not be effective for others. Individual factors such as age, weight, physical activity, and medical history play a role in determining the ideal carb intake for each person. Additionally, long-term restriction of carbohydrates in the diet has been linked to serious complications such as heart arrhythmias, cardiac contractile function impairment, sudden death, osteoporosis, kidney damage, increased cancer risk, impaired physical activity, and lipid abnormalities.

Finally, a well-balanced diet should include a variety of nutritious, whole, unprocessed foods. Low-carb diets that severely restrict or eliminate carbohydrate-rich foods like fruits and vegetables may lead to nutrient deficiencies. Carbohydrate-rich foods provide essential vitamins, minerals, fibre, and antioxidants, which are crucial for maintaining overall health and preventing diseases.

In conclusion, while low-carb diets may be beneficial for weight loss and heart health, they may not be the best option for everyone. It is important to consider individual factors, potential health risks, and the quality of carbohydrate sources when deciding whether to follow a low-carb diet. A well-balanced diet that includes a variety of nutrient-dense, plant-based carbohydrate sources is generally recommended for optimal health.

The best plant-based carb sources

Carbohydrates are an essential component of a healthy diet and can offer excellent health benefits. While low-carb diets can be beneficial for some people, there is no reason to avoid carbs altogether. In fact, many of the healthiest foods are high in carbohydrates.

Beans and legumes

Beans and legumes are a great source of plant-based carbohydrates, protein, and fiber. They are versatile and can be incorporated into a variety of recipes. They have been shown to have positive health benefits, including improved cardiovascular and gastrointestinal health. Additionally, beans may play a role in weight and body composition management.

Whole grains

Whole grains, such as brown rice, quinoa, and oats, are a significant source of carbohydrates and other essential nutrients like B vitamins, fiber, and magnesium. They also provide plant-based protein and can help make a meal more satisfying by keeping you full for longer. Eating whole grains is associated with multiple health benefits, including improved cholesterol, blood sugar, and markers of inflammation.

Fruits

Fruits are often shunned for their sugar content, but they are a good source of fiber, antioxidants, and essential vitamins and minerals. Research shows that eating fruit as part of a healthy diet pattern is associated with many health benefits, including improved digestive and cardiovascular health, as well as a reduced risk for certain cancers.

Starchy vegetables

Starchy vegetables like potatoes, sweet potatoes, winter squash, and root vegetables like parsnips and beets are an excellent source of many nutrients, including essential vitamins, minerals, fiber, and phytochemicals. These vegetables are often cut out when people reduce their carbohydrate intake. However, by preparing these vegetables in healthy ways, you can still enjoy their nutritional benefits.

Non-starchy vegetables

Non-starchy vegetables, such as leafy greens, broccoli, cauliflower, green beans, squash, and tomatoes, are lower in total carbohydrates but are still packed with essential vitamins and minerals. According to the 2020-2025 Dietary Guidelines for Americans, most people do not eat the recommended amount of vegetables daily, so increasing your intake of both starchy and non-starchy vegetables can be beneficial.
