Carbohydrates are an important source of energy for humans and animals. While some people believe that carbohydrates should be removed from diets, they are essential for supporting bodily functions. For animals, carbohydrates can help support digestive functions and overall health. For example, dogs and cats can digest carbohydrates for energy, and they can also aid in weight loss and weight management. The carnivore diet, which consists of animal products and aims for zero carbs, is an exception. This diet is restrictive and controversial, and its long-term effects are unknown.

Carbohydrates are important for energy
Carbohydrates are essential for energy in animals. They are one of the main nutrients that are utilised in an animal's body. Carbohydrates can be metabolised and converted into energy. Simple carbohydrates, such as glucose, are used directly as energy, while more complex carbohydrates are broken down into simpler structures that can be utilised by the body.
Monosaccharides, for example, are the simplest structure of carbohydrates, with a single molecule of sugar. They have a white, crystalline structure and are quick-releasing energy sources. They include galactose, glucose and fructose, all of which follow the formula C6H12O6. Glucose, when in the body, is stored as glycogen in the animal's muscles and liver. Glucose is further broken down in the cells to produce ATP, which is the energy currency of cells. Fructose, on the other hand, is broken down in the liver, and any leftover parts are kept as fat.
Starches, which are a type of carbohydrate, also supply energy over an extended period. This helps give animals the energy required to support basic functions such as breathing, heartbeat and cognitive processes between meals. By utilising carbohydrates for energy, protein is spared and can be used for other vital functions, such as building, maintaining and repairing cells and body tissues.
Fibre, another form of carbohydrate, is especially useful in the diets of animals that need to lose weight or are prone to weight gain. Fibre cannot be digested in the small intestine, so it adds little energy to the diet. This helps reduce the overall energy density of the food. Fibre also increases satiety, making the animal feel fuller for longer, and helps manage blood glucose and cholesterol levels.
Carbohydrates are, therefore, an important source of energy for animals and play a crucial role in supporting overall health and bodily functions.

Cats and dogs can digest carbs
Cats and dogs can digest carbohydrates, but they have different digestive capabilities. Dogs, being omnivores, are adept at digesting carbohydrates, while cats, as carnivores, have a more limited ability.
Dogs' Carbohydrate Digestion
Dogs have evolved during domestication to efficiently digest carbohydrates. They possess the necessary enzymes to break down and utilise carbohydrates for energy. This adaptability is a result of their omnivorous nature and long history alongside humans.
Cats' Carbohydrate Digestion
Cats, on the other hand, have unique nutritional requirements and process carbohydrates differently. They have much lower levels of carb-digesting enzymes compared to dogs, and their ability to adapt to high dietary carbohydrate concentrations is limited. However, it is important to note that cats are not entirely unable to digest carbohydrates. They can utilise carbohydrates as an energy source, and proper extrusion of starches can result in high digestion rates of around 93%.
The Role of Carbohydrates
Carbohydrates play an important role in the health of both humans and pets. While they are not essential, carbohydrates, specifically starches, provide sustained energy release, supporting basic bodily functions. This, in turn, spares protein for other vital roles, such as building and repairing cells and maintaining a healthy coat.
Health Considerations
The belief that carbohydrates are inherently bad for cats is common, with many vets recommending low-carb diets to mitigate the risk of obesity and diabetes. However, research suggests that indoor lifestyles, low physical activity, and obesity are more significant risk factors for diabetes than carb-heavy diets. A balanced approach is recommended, with a minimum of 10-15% of calories from carbs, mirroring their wild diet, and ideally no more than 30%. Additionally, fibre, often derived from carbohydrates, is crucial for cats' digestive health, helping prevent constipation and aiding in hairball management.
In conclusion, while cats and dogs have different digestive capabilities regarding carbohydrates, both can digest and benefit from them in their diets. A balanced approach, considering the unique needs of each species, is essential for optimal health.

Carbs are not essential for dogs
Carbohydrates are not considered essential for dogs. While carbohydrates are not necessary for dogs, they can be beneficial in reasonable amounts as a source of energy. Starches, for example, supply energy over an extended period, helping to provide energy for basic functions such as breathing, heartbeat, and thinking. By utilising fats and carbohydrates for energy, protein is spared to support other bodily functions, such as building and repairing cells and body tissues, as well as maintaining a healthy coat.
However, it is important to note that the quantity of carbohydrates in a dog's diet matters. Using a dog's ancestral diet as a model, the total amount of carbohydrates consumed by a dog's evolutionary predecessor is significantly less than what is commonly found in today's dry dog food, which typically contains 30-60% carbohydrates. Carbohydrates are included in dog food primarily for their practical benefits, such as providing structure and texture, rather than nutritional value.
The energy content of a dog's diet determines how much food should be consumed daily, and the concentration of other nutrients is based on that. For instance, dogs eating a diet high in energy will consume smaller amounts of food. In such cases, it is crucial to ensure that the percentage of other essential nutrients is high enough to meet the smaller volume consumed.
Proteins are essential for the formation and maintenance of muscles, skin, hair, nails, cartilage, tendons, and ligaments. They also assist with hormone, antibody, and blood formation. When broken down, proteins create amino acids that can be reassembled into the proteins a dog needs. Proteins can also serve as an alternative energy source for dogs.
Fibre is another important component of a dog's diet, as it helps maintain a healthy digestive system and normalises bowel movements and faecal consistency. It is particularly useful for dogs that need to lose weight or are prone to weight gain, as it adds little energy to the diet and helps reduce the energy density of the food. Fibre also plays a role in increasing satiety and managing blood glucose and cholesterol levels.
While carbohydrates are not essential for dogs, they can be a good source of energy and support the utilisation of proteins for other bodily functions. However, the quantity of carbohydrates in the diet should be considered, as too much can lead to potential health issues.

The carnivore diet is low-carb
The carnivore diet is a highly restrictive diet that consists solely of animal products, including meat, fish, and other animal foods like eggs and some dairy products. It is sometimes referred to as the "zero-carb" diet because it aims to eliminate all carbohydrates from the diet. Proponents of the carnivore diet argue that it can aid in weight loss, improve overall health, and even treat various health conditions such as depression, anxiety, arthritis, obesity, and diabetes.
The carnivore diet is based on the controversial belief that human ancestral populations thrived mainly on animal foods and that high-carb diets are to blame for today's high rates of chronic disease. However, it's important to note that this belief is not universally accepted and that the carnivore diet can be challenging to maintain in the long term due to its restrictive nature.
Unlike other low-carb diets such as the keto and paleo diets, the carnivore diet does not simply limit carb intake but aims for zero carb consumption. This means excluding all plant-based foods, including fruits, vegetables, legumes, grains, nuts, and seeds. The carnivore diet is, therefore, much stricter than other low-carb diets and may be difficult to follow for extended periods.
While the carnivore diet may lead to short-term weight loss and improved blood sugar control, there are also potential downsides and risks associated with it. Due to the exclusion of plant-based foods, the carnivore diet can be low in certain essential nutrients and may lead to nutrient deficiencies. Additionally, the diet can be high in saturated fat and cholesterol, which may increase the risk of heart disease.
It is important to consult with a healthcare professional or registered dietitian before starting any restrictive diet like the carnivore diet, as individual nutrient needs and health goals should be taken into consideration. While the carnivore diet may offer some potential benefits, it is not a sustainable or balanced approach for everyone and may have negative consequences for certain individuals.

Carbohydrates are needed for dry pet food
Carbohydrates are often blamed for weight gain in pets. However, just as with humans, weight gain in pets is almost always due to too many calories consumed and too few burned, regardless of the nutrient source. Carbohydrates are not essential to a dog's diet for survival, but they do play an important role in supporting the health of both humans and pets.
Carbohydrates, fats, and proteins are the three macronutrient groups that provide the energy needs of dogs and cats. Carbohydrates, including sugars, starches, and fiber, are not essential to a dog's diet, but starches provide energy over an extended period, helping to give animals the energy needed to support basic functions such as breathing, heartbeat, and thinking between meals. By utilizing fats and carbohydrates for energy, protein is spared to support other bodily functions such as building, maintaining, and repairing cells and body tissues, as well as maintaining a healthy coat.
The percentage of carbohydrates in a dog's diet can vary depending on the type of food. In the evolutionary diet, dogs consumed only around 5% carbohydrates from fruits and vegetables or from the stomach of their prey. In contrast, an average dry commercial kibble packet can contain between 30-60% carbohydrate content. The extrusion process required to make dry dog food means a minimum of about 30% starch is necessary to form the dry kibble. Therefore, carbohydrates in dry pet food are unavoidable.
However, pet owners can take steps to reduce the amount of sugar in their dog's diet. One option is to introduce a complete and balanced raw food into the dog's diet, such as Big Dog Pet Foods, which tend to have higher levels of non-starchy carbohydrates that support digestive and immune health and overall well-being. It is also important for pet owners to provide their pets with sufficient exercise and closely monitor their pet's calorie intake, body weight, and body condition score.
