A keto diet is well known for being a low carb diet, where the body produces ketones in the liver to be used as energy. It’s referred to as many different names – ketogenic diet, low carb diet, low carb high fat (LCHF), etc.

When you eat something high in carbs, your body will produce glucose and insulin.

  • Glucose is the easiest molecule for your body to convert and use as energy so that it will be chosen over any other energy source.
  • Insulin is produced to process the glucose in your bloodstream by taking it around the body.

Since the glucose is being used as a primary energy, your fats are not needed and are therefore stored. Typically on a normal, higher carbohydrate diet, the body will use glucose as the main form of energy. By lowering the intake of carbs, the body is induced into a state known as ketosis.

Ketosis is a natural process the body initiates to help us survive when food intake is low. During this state, we produce ketones, which are produced from the breakdown of fats in the liver.

The end goal of a properly maintained keto diet is to force your body into this metabolic state. We don’t do this through starvation of calories but starvation of carbohydrates.

Our bodies are incredibly adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the primary energy source. Optimal ketone levels offer many health, weight loss, physical and mental performance benefits.

Benefits of a Ketogenic Diet

There are numerous benefits that come with being on keto: from weight loss and increased energy levels to therapeutic medical applications. Most anyone can safely benefit from eating a low-carb, high-fat diet. Below, you’ll find a short list of the benefits you can receive from a ketogenic diet.

Weight Loss

The ketogenic diet essentially uses your body fat as an energy source – so there are obvious weight loss benefits. On keto, your insulin (the fat storing hormone) levels drop greatly which turns your body into a fat burning machine.

Scientifically, the ketogenic diet has shown better resultscompared to low-fat and high-carb diets; even in the long term.

Many people incorporate MCT Oil into their diet (it increases ketone production and fat loss) by drinking ketoproof coffeein the morning.

Control Blood Sugar

Keto naturally lowers blood sugar levels due to the type of foods you eat. Studies even show that the ketogenic diet is a more effective way to manage and prevent diabetes compared to low-calorie diets.

If you’re pre-diabetic or have Type II diabetes, you should seriously consider a ketogenic diet. We have many readers that have had success with their blood sugar control on keto.

Mental Focus

Many people use the ketogenic diet specifically for the increased mental performance.

Ketones are a great source of fuel for the brain. When you lower carb intake, you avoid big spikes in blood sugar. Together, this can result in improved focus and concentration.

Studies show that an increased intake of fatty acids can have impacting benefits to our brain’s function.

Increased Energy & Normalized Hunger

By giving your body a better and more reliable energy source, you will feel more energized during the day. Fats are shown to be the most effective molecule to burn as fuel.

On top of that, fat is naturally more satisfying and ends up leaving us in a satiated (“full”) state for longer. If you’re interested in the science behind how ketosis works.

Epilepsy

The ketogenic diet has been used since the early 1900’s to treat epilepsy successfully. It is still one of the most widely used therapies for children who have uncontrolled epilepsy today.

One of the main benefits of the ketogenic diet and epilepsy is that it allows fewer medications to be used while still offering excellent control.

In the last few years, studies have also shown significant results in adults treated with keto as well.

Cholesterol & Blood Pressure

A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. More specifically low-carb, high-fat diets show a dramatic increase in HDL and decrease in LDL particle concentration compared to low-fat diets.

Many studies on low-carb diets also show better improvement in blood pressure over other diets.

Some blood pressure issues are associated with excess weight, which is a bonus since keto tends to lead to weight loss. If you have high blood pressure or other blood pressure issues, click here to learn how keto can reduce blood pressure >

Insulin Resistance

Insulin resistance can lead to type II diabetes if left unmanaged. An abundant amount of research shows that a low carb, ketogenic diet can help people lower their insulin levels to healthy ranges. Read more on keto and insulin resistance >

Even if you’re athletic, you can benefit from insulin optimization on keto through eating foods high in omega-3 fatty acids.

Acne

It’s common to experience improvements in your skin when you switch to a ketogenic diet.

Here’s one study that shows drops in lesions and skin inflammation when switching to a low-carb diet. Another study that shows a probable connection between high-carb eating and increased acne, so it’s likely that keto can help.

What Do I Eat on a Keto Diet?

To start a keto diet, you will want to plan ahead. That means having a viable diet plan ready and waiting. What you eat depends on how fast you want to get into a ketogenic state. The more restrictive you are on your carbohydrates (less than 15g per day), the faster you will enter ketosis.

You want to keep your carbohydrates limited, coming mostly from vegetables, nuts, and dairy. Don’t eat any refined carbohydrates such as wheat (bread, pasta, cereals), starch (potatoes, beans, legumes) or fruit. The small exceptions to this are avocado, star fruit, and berries which can be consumed in moderation.

Do Not Eat

  • Grains – wheat, corn, rice, cereal, etc.
  • Sugar – honey, agave, maple syrup, etc.
  • Fruit – apples, bananas, oranges, etc.
  • Tubers – potato, yams, etc.

Do Eat

  • Meats – fish, beef, lamb, poultry, eggs, etc.
  • Leafy Greens – spinach, kale, etc.
  • Above ground vegetables – broccoli, cauliflower, etc.
  • High Fat Dairy – hard cheeses, high fat cream, butter, etc.
  • Nuts and seeds – macadamias, walnuts, sunflower seeds, etc.
  • Avocado and berries – raspberries, blackberries, and other low glycemic impact berries
  • Sweeteners – stevia, erythritol, monk fruit, and other low-carb sweeteners >
  • Other fats – coconut oil, high-fat salad dressing, saturated fats, etc.

To see more specific advice on what (and what not) to eat

Try to remember that keto is high in fat, moderate in protein, and very low in carbs. Your nutrient intake should be something around 70% fats, 25% protein, and 5% carbohydrate.

Typically, anywhere between 20-30g of net carbs is recommended for everyday dieting – but the lower you keep your carbohydrate intake and glucose levels, the better the overall results will be. If you’re doing keto for weight loss, it’s a good idea to keep track of both your total carbs and net carbs.

Protein should always be consumed as needed with fat filling in the remainder of the calories in your day.

You might be asking, “What’s a net carb?” It’s simple really! The net carbs are your total dietary carbohydrates, minus the total fiber. I recommend keeping total carbs below 35g and net carbs below 25g (ideally, below 20g).

If you’re finding yourself hungry throughout the day, you can snack on nuts, seeds, cheeses, or peanut butter to curb your appetite (though snacking can slow weight loss in the long term). Sometimes we can confuse the want to snack with the need of a meal. If you’re in a rush and need a keto fast food option, there are some available.

Vegetables on a Ketogenic Diet

Dark green and leafy is always the best choice for vegetables. Most of your meals should be a protein with vegetables, and an extra side of fat. Chicken breast basted in olive oil, with broccoli and cheese. Steak topped with a knob of butter, and a side of spinach sauteed in olive oil.

If you’re still confused about what a net carb is, don’t worry – I’ll explain further. Let’s say for example you want to eat some broccoli (1 cup) – seriously my favorite and most delicious vegetable out there.

  • There are a total of 6g carbohydrates in 1 cup.
  • There’s also 2g of fiber in 1 cup.
  • So, we take the 6g (total carbs) and subtract the 2g (dietary fiber).
  • This will give us our net carbs of 4g.

Here’s a list of the most common low carb vegetables. Though if you want a complete list, check out our guide on the best vegetables for a ketogenic diet >

Spinach (Raw) 1/2 Cup 0.1
Bok Choi (Raw) 1/2 Cup 0.2
