Keto Calculator: The Best Ketogenic Calculator for Your Macros

The ketogenic diet keeps carbs very low, usually under 50 g a day, so the body runs on fat and ketones instead of glucose (1). Protein stays moderate and fat fills the rest of your calories. Enter your details and the calculator sets your calories for your goal, then your fat, protein and carbs in grams.

Keto is a very popular diet for weight/fat loss and there are many studies that support the benefits of going keto, not only regarding the physical changes but for overall better health in many cases.

But let’s talk a little more about the diet so that you can have a better understanding if you weren’t aware of how it worked…

How Does Keto Work?

Carbohydrates are usually the main source of energy for most of the population but keto utilizes dietary fats for energy instead. 

And when carb intake is reduced to less than 50g per day for 3-4 days, the body enters a state of ketosis. This results in ketones being formed in the blood which replace glucose as the main energy source.

But ketones also produce more adenosine triphosphate (transports and supplies energy to the cells) than glucose, therefore, it’s an excellent fuel source and even sometimes referred to as a “super fuel”. 

Keto Macro Calculator: on this calculator, fat fills whatever calories are left after protein and carbs, so most results land at about 75 to 85% of calories from fat, 10 to 20% from protein and under 10% from carbs. 

But this can vary based on your goals. Some people need to up the fat intake and lower the carb consumption, and for optimal muscle-building purposes, protein intake may need to be higher as well.

But the reason for a typically moderate protein intake during a keto diet is because too much protein can potentially interfere with optimal ketosis. However, intense weight training will require sufficient protein intake and that’s the bottom line. 

If you lift, the calculator raises protein to about 0.8 g per lb (1.8 g per kg) while you lose weight and 0.7 g per lb (1.6 g per kg) otherwise. The ISSN notes a blood ketone level of 1.8 mM in elite race walkers eating 2.2 g per kg, so that much protein need not stop ketosis.

And this is perfectly ok because there are a few different ways to implement the ketogenic diet. But since everyone is different, you’ll have to find what works best for you.

What Research Says About Keto 

Numerous studies on the keto diet have concluded several benefits for weight loss and health.

The keto diet was originally used to treat epilepsy in the early 1900s and it’s still prescribed for this purpose. But keto has also shown neuroprotective and disease-modifying benefits as well; which means it’s promising for cancers, diabetes, heart disease, etc. (2, 3, 4)

But due to the evident weight loss benefits, keto has seen a huge explosion in popularity around the world. 

Although, there’s more evidence for the efficacy of keto dieting for the short-term than the long-term. But some research has, in fact, supported effectiveness and safety for more long-term implementation.

Even though research is extremely limited for the potential health implications from prolonged keto dieting. 

One 2004 study involved prescribing a 24-week ketogenic diet to 83 obese patients (39 men and 44 women) who also had high glucose and cholesterol levels. (5)

Bodyweight, body mass index, blood sugar, cholesterol, and triglycerides were all significantly lower/improved. And even better, there were no significant side effects noted during the 24 weeks. 

It was concluded that based on the lack of significant side effects, a keto diet for a prolonged duration is safe.

And according to recent scientific literature, low-carb diets are much more effective for weight loss than low-fat diets. 

But low-carb was also found to be superior to low-fat for maintaining basal metabolic rate (BMR), which represents the number of calories required for the body to function normally while in a resting state. (6)

This implies that nutritional quality is correlated with the number of calories burned overall. And keto also usually involves lower caloric intake in general, which is necessary for weight/fat loss.

Not too mention, heart disease, type 2 diabetes, and stroke are associated with low-quality, high-carb diets when fewer vegetables, fruit, nuts, and unprocessed meats are consumed; due to the vital nutrients contained in these foods.

The first week on keto often drops a few pounds of water; the weekly loss the calculator shows is the fat-loss rate you set.

But if you’re trying to improve your body composition with resistance training, then you’re in luck because keto is effective for preserving muscle tissue during a restricted-calorie diet.

But, just because keto is a high-fat diet, it doesn’t mean you can, or should munch on too much or any of less-healthy fats (saturated and trans) as quality nutrition is still completely necessary if you expect to reap the health benefits as with any diet. (7)

So, stick with more of monounsaturated and polyunsaturated/ omega-3 fats instead. It’s better for your heart and the essential functions which fat is necessary for. 

Here’s a list of recommended foods while on a keto diet:

• Pastured meats (beef, turkey, chicken, pork)
• Collagen peptides
• Omega-3 rich fish/seafood (salmon, anchovies, tuna, mackerel, herring, oysters, etc)
• Healthy oils (MCT, cod liver, olive, coconut, sunflower lecithin)
• Nuts (coconut, raw almonds, walnuts)
• Avocado
• Eggs (pastured)
• Low-carb vegetables (dark leafy greens, spinach, celery, squash, etc)
• Grass-fed butter and ghee
• Herbs and spices in a natural state (no added ingredients)
• Keto shakes and snacks
• Bone broth
• Quality coffee and green tea
• Monk fruit, Stevia erythritol, sorbitol, maltitol

Here’s a list of foods to avoid on keto (although, some may consume very small amounts):

• Processed foods
• Roots (potatoes and variations, carrots, etc)
• High-sugar food
• Unhealthy fat sources (trans fats, processed oils, etc)
• Grains (rice, pasta, oats, etc)
• Fruits (Most fruits except limited amount of berries)
• Beans and legumes (green peas, chickpeas, lentils, etc)
• Certain sauces and dressings containing sugars
• Alcohol (sugar content)
• Artificial sweeteners 
• Nutritional yeast
• Common soy products (some exceptions)

Keto side effects and health concerns

As with any diet, there’s a transition period that may cause unwanted side effects. And “keto flu” is a commonly used term for the initial symptoms which may occur.

Keto flu should last a few days and it may even last a few weeks. 

The following symptoms are common with “keto flu”…

• Headache
• Nausea
• Dizziness
• Insomnia
• Fatigue
• Constipation
• Exercise difficulty

Now, symptoms are one thing, but there are a few health concerns that have been associated with the ketogenic diet. And you need to be aware of how your body is reacting. 

If keto flu symptoms last for longer than a few weeks and/or if you experience any of the following issues, then you’ve either implemented the diet for too long, or you’re neglecting to implement it correctly.

Therefore, it’s highly advised to keep up with a medical professional to ensure you’re not compromising your health. 

Potential long-term side effects that may occur include…

• Vitamin and mineral deficiencies
• Kidney stones
• Hepatic steatosis
• Hypoproteinemia
• Dehydration
• Electrolyte imbalance
• Hypoglycemia

How Long Can I Do The Keto Diet?

While keto can be extremely beneficial in many ways, the current recommendation leans toward following this nutritional regime for a minimum of 2-3 weeks and up to 6-12 months. (1)

And always consult with a physician if you suffer from health issues prior to implementing the ketogenic diet.
