What is a Ketogenic Diet?

The ketogenic diet, often known as ‘keto’, is all about forcing your body to use fat for fuel.

Whereas most of us get our energy from carbohydrates, advocates of keto don’t. Instead, they restrict their sugar intake so their body must use fat to survive. The science behind it is pretty cool.

Your body’s preferred source of fuel is carbohydrates. So, whenever there’s carbs around to be broken down into glucose, your body will use them. But…

When you restrict carb intake to drop blood sugar levels, tiny molecules called ketones are produced. For this to happen it’s also important to moderate protein, which can also be broken down into sugars.

To make up for the lack of carbs in your system the liver makes ketones from fat. Once created, these ketones can supply your body, especially the brain, with useable energy. A ketogenic diet is a specific way of eating that allows this process to happen.

People who choose to follow a standard keto diet use fat for fuel every day. Understandably, this makes losing weight through fat burning much more efficient. Utilizing fat for energy by altering diet in this way is known as ‘ketosis’ [1].

Types of Ketogenic Diet

Most people that follow a ketogenic diet focus on the standard version. This is usually the simplest to keep track of and keeps dieters in 24/7 ketosis.

Yet, other variations do exist. Popular types of keto dieting include:

  • Standard Ketogenic Diet: High-fat, low-carb, and moderate protein. This variation usually comprises of 75% fat, 20% protein, and 5% carbs [2].
  • Targeted Ketogenic Diet: Adding carbs in and around exercise
  • Cyclical Ketogenic Diet: Included higher carb re-feeds. These could be two days at the weekend in relation to keto weekdays.
  • High-Protein Ketogenic Diet: Rather than moderating protein, it’s usually increased to around 35%. A common ratio is 35% protein, 60% fat, and 5% carbohydrates.

For the basis of this article we’ll be talking about the standard keto diet. This is the most extensively studied style of eating for ketosis, while other variations are said to be better suited to sports people. Either way, the principle remains the same, which means the following information still applies to them.

Is a Ketogenic Diet for you?

There are many reasons people decide to adopt a ketogenic diet. However, it has to be said that the two standout choices are to lose weight and regulate blood sugar.

Keto can support quick weight loss in a number of ways. Firstly, by targeting fat for fuel, your body is more likely to turn to unwanted body fat too. It becomes efficient at not relying on carbs, therefore making it better suited to blitz through body fat by reducing fat-storing hormones [3].

Secondly, with fewer carbs in your system, you’re holding less water weight. Beginners new to keto should notice a fair few pounds dropped in the first few days alone.

A few folk also claim going keto can improve sport performance. While it may be true for some sports, one recent study suggests it might not work for all [4]. Endurance and ultra-endurance athletes might want to consider it for example. Weightlifters and high-intensity guys – not so much.

So, is a ketogenic diet for you? If your goal is to lose weight, help regulate blood sugar, or excel at endurance sports, then it’s a definite maybe.

Who Should Not Use a Ketogenic Diet

Based on current evidence you should not use a ketogenic diet if:

  • Are on medication for diabetes or blood pressure
  • You’re currently breastfeeding

Disclaimer: SpotMeBro do not advise you undertake a ketogenic diet without discussing your plans with a trained medical professional. Sometimes certain medications must be altered to align with the keto lifestyle.

Health Benefits

Weight loss and performance aside, going keto is suggested to be good for you. Not only can you drop excess bodyfat, but some studies show you can do everything from reduce heart disease risk to boost brain function. Let’s look at some proposed health benefits…


Weight Loss

Studies show that the ketogenic diet may help people lose weight effectively [5]. By losing fat weight men can experience a bunch of other health benefits including higher testosterone and lower risk of mortality from diseases [6].

Also, some scientists suggest that going keto can work for suppressing hunger [7]. Understandably, this can really increase your chance of weight loss by keeping cravings at bay. It might also make intermittent fasting much easier, which could also accelerate fat loss [8].


Managing Blood Sugar and Type 2 Diabetes

By reducing overall carb intake, a ketogenic diet is a great tool for managing blood sugar. People who suffer from type two diabetes might find the diet reduces their medication needs [9].

There have even been multiple studies that say keto could reverse type two diabetes [10] [11].

Boosted Cognitive Performance

According to some research, keto could be the key to better cognitive performance.

Studies show it may hold potentially life changing benefits for those with cognitive disorders. According to researchers, a ketogenic diet can help combat epilepsy, Alzheimer’s, and Parkinson’s [12] [13].

Another thing to consider is that while in ketosis your brain can use ketones as fuel. It just so happens that these small energy molecules are super effective at energizing it too. One clinical review from 2011 states that ketones are even better at the job than glucose [13].

Ketones allow your brain to experience a steady stream of fuel without changes in blood sugar.  In short – you’re less likely to suffer from carb crashes.  This can help stave away common cognitive blips like brain fog and an inability to concentrate.

Keto-friendly food to eat

For food to be keto friendly it should be low in sugars. After all, you’ll only break into dietary ketosis once your body knows there’s limited carbs around.

Here are a bunch of the best options to throw in your meals:

  • Dark chocolate – Go for the variety with 70% cocoa content or over
  • Herbs and condiments – Natural kinds like salt, pepper, basil, coriander etc.
  • Coffee and tea – Caffeine can increase metabolism, improve performance, and benefit mood [15]. So, don’t feel like you must miss out on your joe, bro. Keep carbs low by ditching the spoonful of sugar or frothy milk.

Food to avoid

Just as important as knowing what food to eat is understanding which ones you shouldn’t. It should go without saying that sugars are on the top of this list, but you’d be surprised how many can creep in. Check out this list of ‘avoid’ options:

  • Blatant sugary food – Candy, cakes, table sugar, kid’s cereal, ice cream, chocolate etc.
  • Sugar filled drinks – Soda, juice, really milky coffees, many beers etc.
  • Grains and rice – Oats, bread, pasta, and rice are all carb heavy choices, especially once refined
  • Fruit – Banana, apples, pineapple, mango, pear, etc. are all filled with fructose. A handful of berries every now and again is a better option
  • Beans – While they’re high in protein, these are also rich in carbohydrates
  • Alcoholic beverages – Check the carb of your favorite bottle before drinking – red wine is okay in moderation
  • Some shell fish – Clams, mussels, octopus, oysters, and squid.
  • Unnatural sauces – A lot of condiments and sauces such as ketchup and BBQ are crammed with sugar. Always check the carb content before splashing out on your food.
  • Margarine – No nutritional benefits
  • Artificial trans fats – Linked to poor health markers

If in doubt, use the power of the internet to find an ingredients carb content. Macro maintenance apps like MyFitnessPal are also useful for tracking.

Illustration representing ketogenic supplements


A lot of keto fans carry out the diet to optimize their performance. Their interest goes far beyond fat loss and into the realm of bettering their entire body.

However, a ketogenic diet can be quite restrictive, meaning it’s more likely to miss-out micronutrients. A great way to combat this is to delve into the world of supplements.

On top of this, some supplements might help symptoms of the keto flu. For those curious this is a period, usually only a few days, where dieters feel sick while adjusting to ketosis. Keto flu can make people feel nauseous, low on energy, run down, irritable and have intense sugar cravings. Hence why it’s named after the common ‘flu’.

These are the best go-to supplements for ketogenic dieters…

  • MCT OilMedium-chain triglycerides are the table sugar of the fat world. Once consumed they’re fast-tracked to the liver where they’re converted into energy inducing ketones. Supplementing with MCT oil can help dieters ramp up their fat intake quickly.
  • Magnesium – This mineral plays an integral part in health by boosting energy, bolstering the immune system and managing blood sugar [16]. Also, ensuring you’re hitting your RDA can help with the muscle cramps and sleeping difficulty associated with keto flu [17] [18].
  • Vitamin D – Although not exclusive to keto followers, many of us face vitamin D deficiencies due to our modern lifestyle that sees us hidden from the sun. One study indicates that almost 50% of us might be suffering from it, which makes supplementing a smart move. This is especially true for people in ketosis who may be exposed to limited amounts of calcium [19] [20].
  • Exogenous ketones – These can help keto dieters reach ketosis faster. Some scientists believe they could also suppress appetite, making weight loss an easier process [21].


Keto Diet FAQs

How do I track carb intake?

We recommend good old pen and paper if you don’t have a smart phone. However, if you’ve got access to this awesome technology, download a macro tracking app. This will make it super easy to check in on your daily carbohydrates.


Won’t I eat too much fat?

Not if you’re tracking your calories and weight. If you notice a little fat gain pull the macros back a little. It’s possible to over-eat anything, so it’s all about knowing how to moderate them. If in doubt work out your maintenance calories and set up your fats, carbs, and proteins to match.


How long will it take before I’m in ketosis?

Entering into a ketogenic state could take anywhere between two to seven days. Unfortunately, you might have to put up with keto flu while transitioning. When this occurs stay hydrated, relax, keep away from intense exercise, get your sleep, and ensure you’re eating enough.

The Final Word

The ketogenic diet has become a popular way for people to eat in recent years. Rather than find energy through carbohydrates, keto advocates turn to fats from their food as fuel.

Once carbohydrates become low enough the body goes into ketosis. This is a stage where it will draw energy from ketones, derived from fat, rather than glycogen originated from sugars. Understandably, entering ketosis is seen as an ideal way to target body fat stores.

According to scientific studies, the keto diet may promote certain health benefits. Some of these such as helping to manage Type 2 Diabetes and enhancing cognitive function are quite impressive. Going keto is sometimes used to combat epilepsy too.

If you’re thinking of trying the ketogenic lifestyle, it’s recommended you speak to your doctor. While it’s fine for most people it’s always best to get checked out first. Your doctor will be able to check your current state of health before advising if keto is safe for you.
