Which of the following is a false statement about carbohydrates?


Carbohydrates are an essential macronutrient that provides energy to the body. They are found in various foods such as grains, fruits, vegetables, and dairy products. However, there are some misconceptions surrounding carbohydrates, leading to false statements being made about them. In this article, we will explore and debunk one false statement about carbohydrates.

False Statement: Carbohydrates are the only source of energy for the body

One false statement about carbohydrates is that they are the only source of energy for the body. While it is true that carbohydrates are a primary source of energy, it is incorrect to claim that they are the sole source. In fact, the body can utilize other macronutrients, such as fats and proteins, to produce energy.

Energy from Fats: Fats are an important energy source for the body. When carbohydrates are limited, the body can switch to using fats as an alternative fuel source. This process, known as ketosis, occurs when the body breaks down stored fats into ketones, which can be used by the brain and muscles for energy. This is why low-carbohydrate or ketogenic diets can be effective for weight loss.

Energy from Proteins: Proteins are primarily known for their role in building and repairing tissues, but they can also be used as an energy source. When the body lacks carbohydrates and fats, it can break down proteins into amino acids, which can then be converted into glucose through a process called gluconeogenesis. However, relying on protein for energy can be detrimental as it may lead to muscle loss and other health issues.

It is important to note that while the body can use fats and proteins for energy, carbohydrates are still the preferred and most efficient source. Carbohydrates are easily broken down into glucose, which is readily used by the body’s cells for energy.


In conclusion, the false statement that carbohydrates are the only source of energy for the body has been debunked. While carbohydrates are a primary source of energy, the body can also utilize fats and proteins for energy production. However, it is important to maintain a balanced diet that includes an adequate amount of carbohydrates to ensure optimal energy levels and overall health.
