Keto macros refer to the recommended macronutrient ratios for those following the keto diet. Typically, the macro breakdown for the keto diet includes 5-10% of your calories from carbohydrates.
Your fat intake increases to 55-60% of your calories. The remaining 30-35% of your calories are protein.

The keto diet focuses on a high-fat, low-carbohydrate, moderate-protein intake. With the keto diet, you generally eat less than 50 grams of carbohydrates daily.
Your body usually gets energy from glucose (sugar) from carbohydrates. The idea behind the keto diet is that your body enters ketosis if you lessen your carbohydrate intake. In ketosis, your body burns fat instead of glucose for energy.
Entering and staying in ketosis may lead to weight loss. People on the keto diet may lose weight after maintaining ketosis for 12 months.
Early weight loss on the keto diet may be water weight loss. Weight loss may be from eating fewer calories, not ketosis.
Ketosis may induce weight loss from appetite suppression and hormonal changes. The keto diet protects against increases in the hormone ghrelin, which makes you hungry. The exact level of ketosis to suppress hunger is not clear.
The keto diet may also improve resistance to insulin and leptin, or hormones that help regulate weight.
Following a keto diet requires you to calculate your macro ratio to eat specific portions of carbohydrates, fats, and proteins every day. Counting macros and cutting your intake may be challenging to sustain and restrictive.
A few more flexible keto variations exist. There are modified keto diets that help your body go in and out of ketosis.
1. Standard Ketogenic Diet
On the standard keto diet (SKD), your macro ratio may look like:
Carbohydrates: 10% of your caloriesFat: 70% of your caloriesProtein: 20% of your calories
The SKD is the strictest. On a 2,000-calorie diet, you will eat less than 50 grams of carbohydrates each day.
The initial phase of the SKD may require eating less than 20 grams of carbohydrates daily. This intake restricts several nutrient-packed foods like fruit and whole grains.
2. Targeted Keto Diet
The targeted keto diet (TKD) allows extra carbohydrates for active people and athletes who live a keto lifestyle but need more energy.
The TKD macro ratio may look like:
Carbohydrates: 10-15% of your caloriesFat: 65-70% of your caloriesProtein: 20% of your calories
Healthy carbohydrate sources include:
FruitsMilkVegetablesWhole grainsYogurt
3. Cyclical Keto Diet
Keto cycling is a way to cycle in and out of ketosis while eating a balanced diet. The cyclical keto diet (CKD) approach may include five “keto days” and two “off days.”
Your “keto days” may include the SKD macro ratio, while your “off days” look like:
Carbohydrates: 55% of your caloriesFat: 30% of your caloriesProtein: 15% of your calories
The cyclical keto diet helped reduce body weight among healthy young men. In contrast, the approach did not effectively improve aerobic or strength performance.
4. High-Protein Keto Diet
The high-protein keto diet (HPKD) entails the following macro ratio:
Carbohydrates: 5% of your caloriesFat: 60% of your caloriesProtein: 35% of your calories
Some people may find the HPKD easier to follow than others. It allows you to eat more protein and less fat than the SKD.
Still, the approach may not result in ketosis. Your body may convert protein into glucose for fuel.
Healthcare providers initially developed the keto diet to aid children with epilepsy, which causes seizures. The classic keto diet for epilepsy differs from the keto diet that people typically follow for weight loss.
The classic keto diet focuses on a high-fat, low-protein, and low-carbohydrate intake, which is usually too restrictive for people to sustain.
Many people use the keto diet to help them lose weight and manage conditions like:
Alzheimer’s diseaseCancerHeart diseaseNon-alcoholic fatty liver disease (NAFLD)ObesityType 2 diabetes
Reach out to a doctor before starting a new diet, including the keto diet.
The keto diet requires you to eat a few carbohydrates, a lot of fats, and moderate amounts of protein.
No food is “bad” or “good,” but understanding the nutrients in your food is essential. Different types of carbohydrates, fats, and proteins can affect your health in various ways.
Eating foods high in saturated fat—like beef, butter, cheese, and fried foods—can affect your cholesterol levels and increase your heart disease risk.
The American Heart Association (AHA) advises eating unsaturated fats like:
AvocadosHerringLiquid vegetable oilsOlivesSalmonTroutWalnuts
Some people develop the “keto flu” shortly after starting the keto diet. Short-term side effects include:
ConstipationDizzinessFatigueHeadacheNauseaVomiting
After starting the keto diet, you may have trouble sleeping or working out. A 2018 study found that people had difficulty performing anaerobic exercise (high-intensity, short bursts of activity) after four days on the keto diet.
Is It Safe and Sustainable?
The keto diet may lead to short-term weight loss, but research on its long-term health effects is limited.Â
The keto diet is restrictive and may be challenging to follow for long periods. Restricting your carbohydrate intake may lead to nutrient deficiencies.
Fruits, milk, and whole grains have essential nutrients like calcium, fiber, potassium, and vitamin D. Finding keto-friendly sources of those nutrients is vital.
The keto diet may be unsafe for people with type 1 diabetes. Similarly, whether the keto diet is safe for pregnant people is unclear.
It is worth mentioning that weight loss is a personal decision. Losing weight does not automatically make you “healthier.” Discussing your weight loss goals and methods with a doctor may be helpful.
A nutrient-rich keto diet does not pose significant safety concerns for the general public. More research is needed to know the keto diet’s long-term effects and full potential.
A calorie deficit is more important than your macro ratio when it comes to fat loss. Eating a balanced diet helps manage weight more easily than eliminating or restricting macros.
A balanced diet typically yields the following micronutrient ratio:
Carbs: 45-65% of your caloriesFats: 20-35% of your caloriesProteins: 10-35% of your calories
Successfully losing fat requires realistic goals and steady lifestyle changes that are easy to maintain. In contrast, the keto diet is more suitable for short-term weight loss than other diets.
Try aiming for a balanced diet that includes food groups like:
FruitsLean proteinsVegetablesWhole grains
Decreasing your added sugar, processed foods, and refined grains intake is critical to a balanced diet.
The keto diet might lead to short-term weight loss, but its long-term effects are unclear. Modified keto macros may be less restrictive and easier to sustain than the standard approach.
Talk to a doctor before starting a new diet. The keto diet may be unsafe for pregnant people and those with type 1 diabetes. Low-carb diets may also lead to nutritional deficiencies.
