Macros And Keto: The Importance Of Understanding Macronutrients

Macros, or macronutrients, are the essential building blocks of your body that you get from food. They are the three primary macronutrients—carbohydrates, protein, and fat—that provide the calories needed to fuel your body. On the keto diet, it is important to keep track of your macros to ensure you are getting most of your calories from fat, which is what kickstarts ketosis, a metabolic state where your body burns fat for energy instead of carbs. The typical macro ratio for keto is 5% of calories from carbs, 25% of calories from protein, and 70% of calories from fat.

Macronutrients are the essential building blocks of your body

Protein contributes four calories per gram. Once digested, it is broken down into smaller units called amino acids. Some amino acids are labelled "essential" because your body cannot make them on its own. Amino acids are either converted to energy or play a wide range of vital functions to keep your body working smoothly. They have roles in your immune system, the structure and function of your tissues, and they play a crucial role in the function of your DNA. Animal products such as beef, turkey, chicken, eggs, pork, bison, and lamb tend to be high in protein.

Carbohydrates also contribute four calories per gram. However, this calculation is complicated by fibre, which falls under the carbohydrate umbrella due to its chemical makeup but moves through your body unabsorbed. This is where the concept of "net carbs" comes in. Carbohydrates that are absorbed enter your bloodstream as monosaccharides and are either sent to your cells to be used as fuel, sent to your glucose storage units, or stored as fat. High-carbohydrate foods include rice, wheat, sugar, rye, millet, and starchy vegetables like potatoes and squash.

Fat contributes nine calories per gram. That's over twice the calories of carbohydrates and protein. Fat plays a crucial role in several processes in your body. Every cell is surrounded by a membrane of fat that serves to protect the cell and allow waste out and nutrients in. Fat is necessary for the absorption and assimilation of fat-soluble vitamins, and it plays a role in hair and skin health and the production of hormones. Some common sources of healthy fats include olive oil, coconut oil, grass-fed butter, grass-fed ghee, tallow, lard, and avocado oil.

On a keto diet, the concept of macros is especially important. To enter a state of ketosis, you must limit carbohydrates. This is because, as long as your blood has glucose from carbohydrates to work with, it won't switch over into fat-burning mode. On a keto diet, fat is your friend. Once you're in ketosis, you can consume as much fat as you like without it kicking you out of keto. Protein plays a middle ground. While some people like to keep their protein in the low to moderate range, others can have an abundance of protein and stay in ketosis. Carbohydrates are the one macronutrient that indisputably needs to stay low on keto.

You need to restrict carbohydrates to enter ketosis

The keto diet is a metabolic process that occurs when your body burns fat for energy instead of glucose. This metabolic state is called ketosis. To enter ketosis, your body needs to restrict carbohydrates to a minimum. This is because your body usually breaks down carbohydrates into glucose, which is then used as fuel. When you restrict carbohydrates, your body has to switch to burning fat for fuel instead.

Ketosis has many health benefits. It can lead to weight loss, increased energy, and improved neurological conditions such as Alzheimer's disease and epilepsy. It can also help manage blood sugar levels, making it beneficial for people with Type 2 diabetes. Additionally, ketosis can lower the risk of cardiovascular disease by improving cholesterol levels and lowering triglycerides.

To enter ketosis, most keto diet guidelines recommend limiting your total carbohydrate intake to 15-30 grams per day. However, this may vary from person to person, and some people may need to restrict their carbohydrate intake to less than 50 grams per day to enter ketosis. It is important to note that ketosis is not just about restricting carbohydrates but also about increasing your intake of healthy fats and maintaining adequate protein levels.

When restricting carbohydrates, it is crucial to avoid highly processed foods, sugar, sweetened beverages, starchy vegetables, and fat-free or low-fat dairy products, as these can quickly disrupt ketosis. Instead, focus on consuming high-fat foods such as oils, fatty cuts of meat, and high-fat dairy products.

By restricting carbohydrates and increasing healthy fats, you can shift your body into ketosis, allowing it to burn fat for fuel and reap the health benefits of this metabolic state.

Protein is a building block that your body requires but doesn't directly turn into energy

When following a keto diet, it's important to understand the role of macronutrients, or macros, in your body. Macros are essential building blocks that you get from food and are needed in large quantities to keep your body functioning optimally. While protein is indeed a building block that your body requires, it doesn't directly translate into energy.

Protein is made up of smaller units called amino acids, which are often referred to as the building blocks of life. These amino acids are crucial for various bodily functions, such as healthy brain function, skin, bone, and muscle health, building muscle mass, and recovering after workouts. They also play a role in hormone synthesis and wound healing.

On a keto diet, the focus is on keeping carbohydrates low, as they can interfere with ketosis, which is a metabolic state where your body burns fat for energy instead of glucose. While protein is important, it doesn't directly provide this energy. Instead, the body can break down excess protein and convert it into glucose through a process called gluconeogenesis. However, this process is highly regulated and stable, and studies have shown that it doesn't significantly increase blood sugar levels, even with extra protein intake.

It's important to note that while protein doesn't directly provide energy, it plays a vital role in weight loss and maintaining a healthy body composition. Protein helps to slow down digestion, keeping you feeling fuller for longer. Additionally, it takes longer to digest protein, which means your body burns more calories during the process, making it advantageous for weight loss.

When it comes to keto, it's recommended to consume 15-30% of your calories from protein. This can be achieved by including protein-rich foods such as meat, poultry, seafood, eggs, dairy, nuts, and seeds in your diet.

In summary, while protein is essential for various bodily functions and plays a crucial role in a keto diet, it doesn't directly provide energy. Instead, the body can convert excess protein into glucose through gluconeogenesis, but this process is tightly regulated and doesn't interfere with ketosis.

Carbohydrates inhibit your body's ability to create ketones

Carbohydrates are the one macronutrient that indisputably needs to stay low on a keto diet. The reason for this is that as long as your blood has glucose from carbohydrates to work with, it won't switch over into fat-burning mode. Therefore, to enter a state of ketosis, you must limit carbohydrates.

On a keto diet, fat is your friend. Once you're in ketosis, you can have as much fat as your heart desires and it won't kick you out of keto.

Protein plays a middle ground. While some people like to keep their protein in the low to moderate range, others can have an abundance of protein and stay in ketosis.

Fats play a crucial role in several processes in your body

Fats are also necessary for the absorption and assimilation of fat-soluble vitamins and phytonutrients. They play a role in hair and skin health, the production of hormones, and protection of your organs.

On the keto diet, fat is your primary source of calories and will dictate whether you will gain or lose weight. In a 2,000-calorie diet, this might look like 165 grams of fat, 40 grams of carbohydrates, and 75 grams of protein. However, the exact ratio depends on your particular needs.

Some healthy unsaturated fats that can be consumed on the keto diet include nuts (such as almonds and walnuts), seeds, avocados, tofu, and olive oil. Saturated fats from oils (palm and coconut), lard, butter, and cocoa butter are also encouraged in high amounts.

It is important to note that while fat is essential, overeating fat will cause weight gain or difficulty with weight loss, regardless of the type of fat. Therefore, it is crucial to consume the right amount of fat and not overeat, even if it is a healthy fat.
