Keto Diet Success: The Best Macro Ratios For You

The ketogenic, or keto, diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. The keto diet requires keeping your carb intake low, at around 5% to 10% of your calories, and increasing your fat intake to 55% to 75% of your calories. The remaining 15% to 35% of your calories should come from protein. This shift in macronutrient ratios is intended to put your body into a state of ketosis, where it burns fat for energy instead of carbohydrates and sugar. To achieve ketosis, most people must eat less than 30 to 50 grams of carbs daily. However, the keto diet also requires that most of your daily calories come from healthy fats, with protein in moderate amounts to boost metabolism and support lean muscle mass.

The standard keto diet (SKD)

The SKD is based on the principle of keeping carbs low, protein moderate, and fat high to enter the fat-burning state of ketosis. Ketosis occurs when the body uses fat for energy instead of carbs and sugar, resulting in benefits such as weight loss, increased energy, and reduced cravings.

To achieve ketosis, it is crucial to deprive the body of glucose, its primary fuel source. This means avoiding virtually all carbs and limiting protein, as the body can convert it into glucose when desperate. To compensate for the lost calories, the SKD emphasizes consuming large amounts of fat, which the body uses to produce ketones, an alternative fuel source.

The SKD requires careful monitoring of macronutrient intake, as consuming even slightly too many carbs or protein can disrupt ketosis. For most people, achieving ketosis necessitates deriving 60% to 70% of daily calories from fat, 15% to 30% from protein, and 5% to 10% from carbs.

The SKD is not without its challenges. The extreme carbohydrate restriction may lead to symptoms like hunger, fatigue, low mood, irritability, constipation, headaches, and brain fog. Additionally, the focus on foods high in saturated fat contradicts recommendations from the Dietary Guidelines for Americans and the American Heart Association, potentially impacting blood LDL cholesterol levels.

It is important to consult with a healthcare professional before starting the SKD or any other dietary regimen to ensure it is safe and appropriate for your individual needs and health status.

Cyclical keto diet (CKD)

The cyclical ketogenic diet (CKD) is a form of carb cycling or keto cycling. On the CKD, you eat a high-carb diet for one or two non-consecutive days per week, and a standard keto diet (SKD) for the remaining days. The SKD is a very low-carb diet, with 55-75% of calories from fat, 20-30% from protein, and less than 10% from carbs. On the other hand, on the high-carb days of the CKD, you invert the macros for fat and carbs while keeping protein constant.

CKD is popular among athletes as it is believed to enhance performance. The extra carbs are thought to help with longer, harder efforts like marathons, obstacle racing, and high-intensity interval training (HIIT) that demand glucose for energy. The high-carb days refill glycogen stores, which help athletes recover and prepare for the next exertion.

There are other potential benefits to CKD as well. It may help with weight management, make it easier to stick to the keto diet, and increase gut microbiota. However, there is limited research on the cyclical keto diet, and it may not be suitable for everyone. Some potential downsides include water retention, tiredness, brain fog, and unhealthy food cravings due to increased carbs.

If you want to try the cyclical keto diet, it is recommended to do a standard ketogenic diet for a full month first to allow your body to reach a fat-adapted state. Once you've become fat-adapted, choose five or six days of the week to eat low-carb (50 grams or less) and stick to that plan. For the remaining one to two days, increase your carb intake to 70-80% of your total calories. Focus on complex carbohydrates like sweet potatoes, chickpeas, beets, butternut squash, and grains on these high-carb days. After the refeeding phase, return to ketosis immediately.

Targeted keto diet (TKD)

The targeted keto diet (TKD) is designed for active people and athletes who follow a keto lifestyle but need more energy. The TKD macro ratio typically includes 10% to 15% of your calories from carbs, 65% to 70% from fat, and 20% from protein.

On the TKD, you can consume healthy carb sources such as fruits, milk, and whole grains. It is important to note that even with the slightly higher carb allowance, you should still aim to keep your total carb intake under 50 grams per day to maintain ketosis.

The TKD can be beneficial for active individuals who need the extra energy boost from carbs to support their training and performance. However, it is crucial to carefully track your macros and ensure that you don't exceed your carb limit to stay in ketosis.

Additionally, when following the TKD, it is recommended to consume most of your carbs before and after your workouts. This strategy will help optimize your muscle glycogen levels and fuel your training sessions.

Remember that the TKD is just one variation of the keto diet, and there are other options available, such as the standard keto diet (SKD) and the cyclical keto diet (CKD). The best keto diet for you will depend on your lifestyle, activity levels, and specific goals.

High-protein keto diet (HPKD)

The High-Protein Ketogenic Diet (HPKD) is a variation of the standard keto diet. While the standard keto diet includes 75% fat, 15-20% protein, and 5-10% carbs, the HPKD includes 60-65% fat, 30% protein, and 5-10% carbs.

The HPKD is similar to the standard keto diet in that fat makes up the majority of your daily macronutrient intake. However, the HPKD requires eating a higher percentage of protein. On the HPKD, you would eat around 120 grams of protein each day, or about four palm-sized servings.

The benefit of the HPKD is that it is easier to implement than the standard keto diet. The standard keto diet requires eating a lot of fat (around 150 grams) every day, which some people find intimidating. The HPKD allows people to ease into keto by eating more protein and less fat.

The drawback of the HPKD is that excess protein in your body is converted to glucose and used as fuel, which can hinder your ability to get into and stay in ketosis. When you are in ketosis, your body burns ketones as fuel, which are created by the liver from stored fat, rather than glucose.

The HPKD may be easier or harder than the standard keto diet depending on the individual. Some men may prefer the HPKD because they are wired to eat more protein and find it hard to reduce their intake. Even if you are not always in ketosis with the HPKD, you will still get the benefits of eliminating sugar and processed carbs from your diet, including weight loss, increased energy, fewer cravings, and better sleep.

The HPKD is not suitable for people who are insulin-dependent, have liver or kidney problems, or are pregnant or breastfeeding. Before starting the HPKD, it is important to consult with your healthcare provider to ensure that it is safe for you.

Ketosis and weight loss

The ketogenic, or keto, diet is a low-carbohydrate, fat-rich eating plan that has been used for centuries to treat specific medical conditions. In the 19th century, the ketogenic diet was used to help control diabetes. In 1920, it was introduced as a treatment for epilepsy in children. More recently, the keto diet has gained popularity as a potential weight-loss strategy.

The basis of the keto diet is to shift your body into a state of ketosis, where it uses fat for energy instead of carbohydrates and sugar. To get into ketosis, you must deprive your body of its primary fuel source, glucose, which is obtained by breaking down carbohydrates and sugar. This means that you have to drastically reduce your carbohydrate intake, limiting them to less than 50 grams per day, or even as low as 20-30 grams per day.

In addition to reducing carbohydrates, the keto diet also involves increasing your fat intake. On the keto diet, 55-75% of your calories should come from fat. This high fat intake provides the body with an alternative fuel source called ketones, which are produced from stored fat. The remaining 15-35% of your calories should come from protein.

It is important to note that eating too much protein can prevent ketosis, as the amino acids in protein can be converted to glucose. Therefore, it is recommended to keep protein intake moderate, ensuring you get enough to preserve lean body mass, but not so much that it interferes with ketosis.

When following the keto diet, it is crucial to monitor your macronutrient intake closely. Eating even a small amount too many carbohydrates or protein can throw you out of ketosis. This is because carbohydrates raise insulin levels more than other macronutrients, and rising insulin will quickly kick you out of ketosis. Therefore, it is recommended to keep carbohydrates below 10% of your total calories and closely monitor your protein intake to ensure you are getting enough, but not too much.

The keto diet has been shown to be effective for weight loss. Research has found that people following the keto diet may lose weight after maintaining ketosis for 12 months. Ketosis may induce weight loss through appetite suppression and hormonal changes. The keto diet protects against increases in the hormone ghrelin, which makes you hungry. Additionally, the keto diet may improve resistance to insulin and leptin, hormones that help regulate weight.

In conclusion, the keto diet can be an effective tool for weight loss, but it requires strict adherence to the recommended macronutrient ratios and careful monitoring of your food intake to ensure you stay in ketosis. It is also important to note that the keto diet may not be suitable for everyone, and it is always recommended to consult with a healthcare professional before starting any new diet.
