We’re currently living in an age of faddy celebrity endorsed diets, so-called “miracle weight loss programs” and supposed quick fixes designed to help people lose weight as quickly as possible. Whilst there are certainly diets, supplements, and weight loss programs out there that do indeed work, unfortunately there are also many, many scams that are nothing more than placebos and are marginally effective at best. One method of dieting, or rather one method of losing weight that has proved to be extremely effective over the last few years however, is a low carb dieting/lifestyle program known as the ketogenic diet, or keto for short. Here we’ll be providing a basic guide to the keto diet and answering the question “What can you eat on a keto diet?”.
It can take us a number of weeks in some cases to lose 2 or 3 kgs, yet one or two unhealthy meals and/or snacks, and back they come. Weeks to lose, and hours to gain back. It’s not really fair but life can be ironic in that sense as it seems as if everything we tend to enjoy, will shave years from our lives, will cause us to gain weight, and will just generally harm our health. In order to lose weight, people all over the world are undertaking various diets designed to speed up and promote weight loss, with many of them seeing mixed results at best. Over the years however, low carb diets have been hitting the headlines and have been yielding some pretty amazing weight loss results if truth be told. In order for low carb diets to be effective, the body has to fall into what is known as a state of ketosis, and it is ketosis and ketogenic dieting we’ll be looking at here. If you’re wondering “what can you eat on a keto diet?” then by the end of this post you should have all of the answers you require.
What is ketosis?
Ketosis refers to a metabolic state within the body, in which it starts to break down stored body fat and burn it off, converting it into energy as it does so. Once a person falls into ketosis, this basically means that the number of ketone bodies found within their blood has now increased to above average levels. Ketones are actually by-products of broken down fatty acids. Put simply, ordinarily the body will convert calories into glucose sugar to be used as energy. Carbohydrates are much easier for the body to convert to glucose than other foods, which means that the body is able to metabolise them and convert them into energy very quickly. As a result of this, as the body is quickly able to obtain the energy it needs from carb sources, any leftover will be stored as body fat as an emergency energy source for a later date. By taking away the carbs however, the body struggles for energy and begins to panic, looking elsewhere for other energy sources. After a few days of low to no carbs, once the body has now accepted the fact that it simply is not getting enough carbs, it will fall into a ketogenic state, and will begin burning body fat as its primary energy source.
What exactly is a ketogenic diet?
Before we answer the question of “what can you eat on a keto diet?”, let’s first discuss quickly what a ketogenic diet actually is. A ketogenic diet is a form of low carb diet in which the body is forced to produce ketones from the liver as a primary source of energy, thus falling into a state of ketosis. Before we look at why a ketogenic diet works so well for rapid weight loss, let’s quickly look at some of the key (and important) mechanics involved.
Glucose – Glucose is a form of sugar and is so effective because it is the simplest molecule for our bodies to convert into energy, and as a result, glucose will always be the body’s natural choice of energy, because it is the easiest.
Insulin – Insulin is a hormone secreted by the pancreas to help process glucose found in the bloodstream. Since the body is using glucose as its primary source of energy, it doesn’t require fat to be used as energy as well, and so it stores fat to be used for energy at a later date, much like we would store fire wood in the summer to be burned during the winter.
A ketogenic diet works because as you lower your intake of carbohydrates, the body will be forced into a ketogenic state, which is a natural process that the body creates when food intake is low in order to keep your body alive and functional. Generally, when making the switch over into keto, it takes the body around 3 – 4 days to fall into ketosis. During ketosis, the liver produces ketones which help to metabolise fat within the body which are then used as a primary source of energy. Simply put, when the body doesn’t have access to glucose molecules for energy, it falls into a ketogenic state, which forces it to use body fat as its primary source of energy instead. Meaning we burn fat whilst fuelling our bodies.
What can you eat on a keto diet?
When talking about ketogenic diets, one diet which you will almost certainly have heard of, is the Atkins diet. There are numerous different variations of ketogenic diet, though they all offer the same benefits and require dieters to consume the same varieties of food. Ketogenic diets will yield speed and impressive weight loss results for people who steer clear of carbohydrates and simple sugars. Instead, the foods they consume will be high in protein, and will contain moderate amounts of healthy fats. Meats, eggs, seafood, cheese, nuts, seeds, cream, black coffee and green leafy vegetables are all great keto diet friendly foods. What amazes people is the fact that a person in ketosis could sit down for breakfast, and tuck into a 3 egg omelette, sausages, and bacon, all fried in butter, and still lose a substantial amount of weight.
List of foods you can eat on a keto diet:
Before starting a ketogenic diet, planning is most definitely essential as the types of foods you consume will dictate just how long it takes you to fall into a ketosis, and whether you will maintain that ketogenic state. Generally, the less carbs you consume, the quicker you will fall into ketosis. The general guideline is 20 – 30g max of carbs per day, although to begin with, some people go as low as 15g of carbs per day. So what can you eat on a keto diet? Generally, the types of foods you are allowed and encouraged to eat are:
- Healthy fats (nuts, avocados, olive oil, coconut oil, seeds etc)
- Green leafy vegetables (broccoli, kale, spinach, lettuce, Bok Choi etc)
- Green beans
- Sour cream
- Cottage cheese
- Sugar-free beverages
Foods to avoid:
- What products
- Root vegetables
- Fruit juice
- Full-sugar beverages
- Breaded produce
- Produce with added wheat or rusk (certain sausages, burgers etc)
- Corn produce
- Starchy vegetables
- Processed foods
The benefits of ketogenic dieting
Now that we’ve answered the question “what can you eat on a keto diet?”, and that you’re now aware of the main benefit of ketosis, let’s take a look at a few more benefits as well, some of which you may not have considered:
Speedy fat loss – Obviously, the main appeal of ketogenic dieting is the fact that not only does it allow dieters to burn off some serious body fat, but it’s also the speed in which the weight comes off that impresses people. If done right, you could lose as much in the first two weeks of ketosis as it would take most conventional dieters to lose in six weeks.
Increased energy levels – As mentioned, it takes around 3 – 5 days on average for a body to fall into a state of ketosis, and during those days you will feel pretty awful. You will be tired, sluggish, irritable, and may suffer from a headache. Once you reach ketosis however, you will feel incredible. Your body will begin burning your body fat as its primary energy source, and the more you have, the more energy you will enjoy.
You actually excrete body fat – Once the body has no use for ketones which have done their job, they are actually excreted in our urine, which means essentially we’re peeing out our own body fat. You can actually purchase special strips that you pee on that will turn a different colour when they detect the presence of ketones.
Ketosis also reduces hunger – Another great benefit about being on a ketogenic diet is the fact that unlike most other diets, you will very rarely ever feel hungry. We’ve answered the question of “what can you eat on a keto diet?”. This diet isn’t about counting calories or restricting fats, it’s basically about cutting out carbs and sugar. If you feel hungry, you can simply go and whip up a quick smoked salmon and spinach omelette without feeling guilty. As protein is also harder to digest than other foods, not only will it boost your metabolism, but it will also keep you feeling full for longer as it stays in your stomach for longer.
So there you have it. In answer to the question “what can you eat on a keto diet?”, you know now exactly what you can eat and how to make a start on a keto diet. Ketogenic diets are safe if done correctly, and are also extremely effective, but they must be adhered to extremely strictly as if done incorrectly, not only will you not lose weight, you could actually even end up gaining weight. The aim is to keep carbohydrate intake at around 20 – 40 grams per day, and considering one sugary drink can contain as much as 90 grams of carbs, one sugary drink could literally ruin everything.

5 Additional Fat Burning Super Foods
I know, you came here asking “What can you eat on a keto diet?” and now we’re throwing yet another 5 fat burning super foods are you. Well, you’re welcome!
Broccoli rabe – Broccoli rabe is without question, one of the healthiest and most beneficial foods a person looking to lose weight could ever consume. Broccoli rabe is rich in vitamins, minerals, and antioxidants, and it is low in calories and virtually fat free. It is an ingredient known as Sulforaphane, which is especially beneficial however, because this phytonutrient contained in the food, actually communicates with our fat cells, stimulating enzymes that tell our fat cells to burn fat as their primary energy source.
Salmon – Salmon is another food that is hugely beneficial for people looking to burn fat, and yet despite this, because it is an oily fish, people tend to shy away from it. It is the oil in the fish that makes it so healthy and beneficial however, as these omega 3 fatty acid oils, help benefit the body in numerous different ways. To begin with, these fatty acids help promote brain, organ, joint, eye, and bone health, and on top of that, they also help boost the metabolism, allowing us to burn more calories and enjoy more energy as a result. As if that wasn’t enough, as the protein in the salmon is a thermogenic compound, this means that the body has to work harder than usual to digest the food, break it down, and extract the nutrients. As it is working harder, it burns more calories and increases the metabolism further.
Chicken breast – Again, another great source of protein, chicken breast too creates that same therogenic effect on the body when we try to digest it and break it down. On high protein, low fat foods such as chicken breast, to simply digest and break down the food, we burn a whopping 30% of the calories that the food contained. So, say we eat a chicken breast containing 300 calories, we would burn around 90 calories just by digesting it. It is also naturally low in fat.
Chilli peppers – Probably not something you expected as an answer to the question “What can you eat on a keto diet?” but read on as chilli is an incredible weight loss aid! It is a compound contained within chilli peppers, known as capsaicin, that is responsible for giving them their fiery and spicy finish. The capsaicin however, can help us to burn calories as it has been found to naturally increase our resting metabolisms. The reason for this is that as we consume spicy chilli peppers or foods containing spicy chillies, they actually increase the core temperature of our bodies, which causes us to burn more calories. Even as our core temperature drops, we still burn additional calories for a while, as the body things it is now getting too cold, and so burns more calories to try to generate more energy to heat it through. That is why people in colder climes, the arctic for example, require far, far more calories than our average requirements over here, just to maintain their weight.
Brazil nuts – Brazil nuts are a keto dieter’s best friend, as they are diverse, they’re tasty, they’re a great source of energy, and they also help to burn fat. These nuts actually help to increase metabolic function within the body, converting our thyroid hormone into its natural and active form, making it more efficient. As you may or may not know, individuals with underactive thyroid glands often suffer from a suppressed metabolism, making it far easier for them to gain weight, and far more difficult to lose it. Keeping the thyroid hormone healthy and active is essential for adequate thyroid health, which is why Brazil nuts are considered so beneficial for weight loss.
