The Fastest Natural Way to Lose Fat without Losing Muscle: The Ketogenic Diet - A Bodybuilding Perspective

Since the ancient times, the Inuit tribes of the arctic regions have lived only on a diet comprising of meat, fish, and fish and animal oils. And these people are absolutely healthy as compared to the vegetable and farm produce eating people of the rest of the world. And this becomes a hot topic of debate for everyone in the field of dietary sciences, medicine and fitness.

How are these tribes healthy even though they eat only meats and oils - that's only proteins and fats?
There have been theories that their genetics are responsible - but these theories have been smashed by research and studies and the pioneering effort of an explorer by the name of VILHAMJUR STEFFANSON, who actually made himself a subject to the experiment an lived entirely on an inuit diet - without any sideeffcts whatsover. 

This diet, comprising of only meats and oils is called a KETOGENIC DIET.

KETOGENESIS: What does it mean?
The human body, as widely studied in the agrarian world today, widely relies on glycogen (carbohydrates) for producing energy for its functions. Now when this abundant energy source of glycogen, for some reason depletes and is no longer available to the liver, the body triggers a survival function. The body now starts breaking down Fatty acids and Proteins for energy production. Much like switching a car engine from petrol to CNG, or an electrical source from AC to DC.
As per the wikipdia: When glycogen stores are not available in the cells, fat (triacylglycerol) is cleaved to provide 3 fatty acid chains and 1 glycerol molecule in a process known as lipolysis. Most of the body is able to use fatty acids as an alternative source of energy in a process called beta-oxidation. One of the products of beta-oxidation is acetyl-CoA, which can be further used in the citric acid cycle. During prolonged fasting or starvation, acetyl-CoA in the liver is used to produce ketone bodies instead, leading to a state of ketosis.
How does Ketosis help in BodyBuilding? 
When it comes to competitive bodybuilding, there are two stages: Gaining and Cutting.
The usual gain phase is where the athletes are on a high carb, high protein diet supplementing their workouts as they are trying to gain as much muscle mass (size) as possible.

The cutting phase is when a bodybuilder is trying to cut down on fat so that the muscle definition can be seen through the skin. Therefore in the cutting phase, many bodybuilders switch to a ketogenic diet - of only high amounts of proteins and healthy fats (especially rich in omega 3) - thus forcing their bodies to burn all the fat that they have accumulated for energy and thus cause a higher rate of fat loss without losing too much muscle mass. 

A must mention here would be the difference between the classical ketogenic diet and the K11 Ketogenic diet / bodybuilding ketogenic diet.

The classical ketogenic diet is 75%  fat, 20% protein and 5% carbs.
While the K11 ketogenic or the bodybuilding ketogenic diet is 70% Protein and 25% fat and 5% complex carbs.

Can you keep switching between ketosis and a regular diet?
NO. unless you are doing it just for fun and results don't matter. which i hope is not the case.
Coz as i said before, it is a switch in the system. Your body is switching to an alternate energy source. It takes time for your body to adapt to it. and once it has adapted to it, it takes time for your body to switch back to accepting glycogen as the primary energy source.

If you are going on a ketogenic diet, to test if your body has actually switched to ketosis for energy, you can test your urine with KETOSTIX. It is a commonly used diabetic testing aid that tests the levels of ketone in your urine. 

KETOSIS FAILURE: if you consume more than 30 grams of carbs in a day, your body will automatically switch back to buing glycogen for energy. The 30 gms limit varies from person to person - some people shift to ketosis on higher amounts too. but 30 gms is considered the usual standard. Even when you are aiming for 30 gms, you should actually try to not consume any carbs at all - because still 30 gms will sneak into your diet. The only carb allowed on ketosis is green leafy vegetable salad a day - thats spinach, lettuce, methi, brocolli for fiber. Mind you, there are no cheat days on a ketogenic diet. But if you want to make it a longterm diet, you could take a break day every 15 days, followed by an intense workout the next day to immediately deplete all the glycogen so that your boy can switch back to ketosis asap.

What 'to and not to' eat on a Ketogenic Diet?
PROTEIN SOURCES: Meats, Eggs, Poultry, Fish, Paneer and HYDROLYSED WHEY PROTEIN.
FAT SOURCES: Fish Oils, Cheese, Peanut Butter, Olive Oil.
One bowl of salad of spinach, methi, lettuce and broccoli every day.
Avoid milk. No sugar. No grains. No Beans. No Agro produce whatsoever. 

What Supplements enhance a Ketogenic Diet for fat loss?
Whey Isolates, Fish Oils, Carnitine, Caffeine, Guarana, Yohimbine.
PS: Switching off carbs can sometimes result in cramping of muscles during intense workouts.
Taking a potassium supplement and a zero carb BCAA mixture with salt keeps muscle cramps and fatigue at bay. If you have enough salts in your diet, this wouldn't be an issue.

Does a ketogenic diet affect your fitness levels?
Now this is a point on which many fitness professionals would argue. Professional bodybuilders that i have spoken to say that your strength reduces on a ketogenic diet - which is scientifically quite sound. You might not be able to lift the same amount of poundage on a ketogenic diet as you might be able to on a fully carb loaded day. 
But research argues that not only are the inuit tribes STRONG and RESILIENT in terms of endurance, but also explorer  Frederick Schwatka, pulled off one of the greatest feats of endurance (long distance sledging across the arctic) on a fully ketogenic diet.
From my own experience i can say that as my body is used to carbs as a dominant source of energy, when i switched to ketosis, the first week was a struggle. I felt drained, weak and not as strong as usual. Even my poundages (amount of weight i lift in a particular exercise) dropped considerably. But by the second week i was feeling quite normal and my poundages returned to normal - in fact i was feeling quite lighter and breezier. I don't discount a feeling of placebo here In both situations. Losing weight and gaining a definitive muscle definition might have made me feel stronger and more confident. While the autosuggestion of people and years of thinking that carbs give the body energy, into me believing that i got a little weaker.
addendum: my recent studies show that my poundages are perfectly high and normal right upto my personal records even on ketogenesis.

Can you run a marathon on ketosis?
Now this is a question where people generally succumb to common perception. They believe that since they have always read about carb loading and glucose refilling during marathons, you probably cant run a marathon or do a highly intensive endurance activity on Ketosis. BUT THEY ARE WRONG.
Since most of the initial studies done on ketosis were actually endurance activities iun extreme conditions, its actually a no brainer that ketosis works perfectly well even on endurance tasks.
If there was any doubt about it still, a friend of mine who is a marathon runner - ZEEBA KHAN, recently volunteered to run marathons on a ketogenic diet. She actually managed to better her time runnin on a ketogenic diet since it made her lose weight without losing her muscle mass and endurance capabilities.

How do you prevent binging or control food cravings on a ketogenic diet?
I keep a snack pack at hand all day. Infact, on a ketogenic diet, im constantly eating.
My snack poack contains Almonds, walnuts, cheese cubes, almond barfiis (sweets) sweetend with sugarfree and sugarfree chewing gums. These hold me off very well uptill the next meal.

What are the FAT LOSS results on a ketogenic diet?
In a nutshell, I lost 4 kgs on a purely ketogenic diet in a month - and most of it was fat loss. Most of my muscle and water remained intact. Which is always the greatest challnege in the war against fat. To lose weight without compromising strength or getting weaker.

But come what may, if you plan to adopt this diet and find the need for consultation, do consult a proper nutritionist and a not a quack.
It is also reasonably expensive to maintain in areas where meat is not abundant. 
So, be wise. Do your own research. Consult an expert. and all the best!

  2. Awesome article! I've been experimenting with getting my macros just right while in ketosis, while attempting to maintain strength in gym. The balance is quite difficult I've found. Maybe i haven't become quite adapted.

  3. I'm trying to keep up with this diet, but it's freaking hard to get under that 30g carb limit. I end up with 40 to 50. It's also bloody difficult to eat 3000 calories each day. That's a lot of food! I've been trying for a couple of weeks to get this diet right, and I'm getting closer. I'll try again Monday.

  4. Interesting topic man. I might try this diet soon. I'll let you know the results. I do however take d-fine8 to help keep muscle fatigue at bay, I even wrote a post about it. Check this post. Would that matter or no?

  5. I have one more question that I am hoping you to answer. What do you say about choosing prohormone supplements? Please share some tips with me.

  6. if i have to boost hormones, i'd rather directly go for steroids than to use some unproven 'prohormone' supplements that would screw up my liver and not even give me 1/1000th the benefit.

  7. Good article! I have a doubt though. When you say bodybuilding ketogenic diet is 70% protein, 25% fat and 5% complex carbs, what is this percentage of? Is it the percentage of total calories? for example, if my total calorie consumption is 3000 calories, does 70% need to come from protein, 25% from fat and 5% from carbs? or is it something else?

  8. The % is in terms of total grams consumed. since counting calories is not always possible accurately. its easier to count grams.

    1. Thanks for replying. But, don't you think this approach changes the structure of the diet. Especially since fat has more than twice the calories as protein, dividing total calories in a 70:25:5 ratio will be totally different than dividing total grams consumed in the same 70:25:5 ratio.

    2. try it and let me know. im currently consuming 400gms of protein per day + 40 grams of cheese + 1 bowl of almonds and broccoli/spinach per day. and im cutting down on a daily basis. i should be shredded in 10-12 days more.

    3. I do plan to go on keto next month at a BW of 80kg. Accordingly, I have decided to have 280g protein (3.5g/kg) and 20-22g carbs (300g spinach and 10g isabgol/psyllium husk) per day. The only doubt is about fat intake. As per your approach, I need to consume 150g fat per day, which to me seems rather high. I was also having a look at Dave Palumbo's keto diet guidelines, and he advises consuming 0.5g fat/lb (which comes to 88g in my case). I only need to clear this up. so that I can get on with keto without any doubts still lingering. What will you suggest?

  9. Informative article. I have some questions, would be thankful if you could answer them:
    a. With 70% protein intake, what advice would you give to someone who is prone to kidney stone?
    b. The article talks about the function of fats in ketogenic diet, but does not tell us the complete function of protein, esp with a figure as high as 70%? (sorry for my ignorance)
    c. What is the source of biotin or live bacteria in your recommended diet? Would you recommend inclusion of natural yogurt?

  10. Your website is terribly informative and your articles are wonderful. Lawrence

  11. hey i have a few basic questions might look like a beginner to you .. firstly i have not been wt training for sometime but i do a lot of dancing and cardio related activities does this diet help that workout plan ?
    I want to reduce body fat percentage does it help with that ?
    When you mean avoid agro products does that include fruits and veggies completely ?
    If you can share an example of your daily diet it would be of help ... I am extremely sorry for my total ignorance on this subject .
    But i want to learn and know .
