The Keto Diet
Use fat as your body’s main fuel source
The Ketogenic Diet, or Keto Diet, is a low-carb, high-fat eating plan that has become immensely popular. This diet is known for its potential benefits in weight loss, which have been supported by scientific studies. When following a Keto Diet, the drastic reduction in carbohydrate intake causes the body to enter a metabolic state called ketosis. In ketosis, the body becomes highly efficient at burning fat for energy instead of glucose, which can lead to weight loss, improved mental clarity, and better blood sugar control.
The Ketogenic Diet was originally developed in the 1920s as a treatment for epilepsy. However, since the 1990s, it has gained popularity in other circles as well. The Keto Diet shares many similarities with the Atkins Diet, which has been around since the 1970s. The difference is that you gradually increase carbs on Atkins, something you don’t do if you following a Ketogenic Diet.
When following a Standard Ketogenic Diet (SKD) you should eat around 70% fat, 20% protein and 10% carbs. To stay in ketosis, you need to cut your carb intake to 20g. Examples of foods included in the Keto Diet are meat, fish, eggs, nuts, butter cream, cheese and low carb veggies.
Eggs are a great source of both protein and fat when going on a ketogenic diet. Eggs are a highly nutritious and they are packed with with essential nutrients like vitamin A, D, E, and B12, as well as riboflavin (B2), folate, and selenium
Build your meal around proteins like steak, chicken, red meat, turkey, bacon, or ham. Alternatively, use a fatty fish like salmon or tuna as the base of your meal. Make sure your source of protein makes up at least 20% of your plate.
As you are limiting the carbs on a Keto Diet, it's important to get enough fat for fuel. Eat lots of fat from foods like butter, full fat cream, cheese, avocados, nuts and healthy oils.

As the Keto Diet is a low-carb, high fat diet, any food that is high on carbs should be avoided to keep the body in a state of ketosis, where it burns fat for energy instead of glucose. Therefore, avoid all grains and starches, such as pasta, rice, potatoes, cereals, couscous, and bulgur. Let go of all ultra-processed foods like ready meals, chicken nuggets, ice cream, chocolate bars, candy, cookies chips and fast food. You should also avoid all sodas and sugary beverages, including fruit juices and smoothies.
High-carb fruits and starchy vegetables are also off-limits when you’re on a Keto Diet. A good rule of thumb for vegetables is to eat only those that grow above ground.
Legumes and pulses, such as lentils, beans, and peas, should be limited as well. Dairy products are okay if they’re full-fat and unsweetened, but avoid milk due to its high lactose content. Be cautious with high-sugar condiments and sauces like ketchup and barbecue sauces. Lastly, you should avoid low-fat or fat-fee products. These products usually contain added sugars to enhance flavor.
The ketogenic diet was originally developed to treat epilepsy in children and remains a highly effective treatment for reducing seizures. It’s also a diet that has become very popular for its weight loss potential. There are many studies confirming that the Keto Diet is an effective way to lose weight because it boosts metabolism and reduces appetite. When the body enters a state of ketosis, blood sugar levels decrease, and insulin sensitivity improves.
The keto diet also has the potential to increase levels of “good” cholesterol, known as HDL cholesterol, while reducing triglycerides. These changes can improve heart health because high levels of fasting triglycerides are a risk factor for heart disease. Another benefit of the Ketogenic Diet is that it can lower blood pressure and we all know that high blood pressure is another risk for heart disease.
Many people that is following a Keto Diet, report improved mental clarity and focus. This is because the ketones that are produced during ketosis, are an efficient energy source for the brain. This can potentially enhance the cognitive function. When in ketosis, you will also experience increased energy levels throughout the day. The keto diet prevents blood sugar spikes and crashes in energy.
Another health benefit of the Ketogenic Diet is that it can help reduce inflammation in the body. This due to lower insulin levels and decreased sugar intake. Lower inflammatory markers is beneficial for overall health and longevity.

One of the primary ketones produced is acetone, which can be excreted from the body through urine, sweat, and breath. This is why your breath may smell strange while on the keto diet—it’s a sign that your body is in fat-burning mode. The phenomenon is referred to as “keto breath”.
