It’s safe to say the keto diet has increased in popularity over the years. Many are adopting this regime not just for weight loss but for the substantial benefits it brings to health.
The keto diet bucks the trend when it comes to diets and there is even reason to suggest it works better too.
If you’ve been hearing lots of great things about the keto diet and want to know what it’s all about, I’m going to run through with you the fundamentals to help you build a better understanding; therefore think of this as your guide to the keto diet.

What is the Keto Diet?
The keto (or ketogenic) diet is a meal plan which emphasizes heavily on a low carb regime. Cutting out carbs means it’s backed by a high fat and moderate protein intake. The keto diet is said to help you effectively lose weight with health benefits. 1
You may have heard of the Atkins diet. This diet plan follows some of the basic principles of keto at the offset although it gradually introduces more carbs towards the final phases.
So what’s the deal with the keto diet?
In simple terms, the keto diet switches the body’s fuel supply. Reducing your carb intake encourages your body to divert from its conventional source and instead burns fat for energy.
So has this got you wondering how this is all possible? Well, it’s with a little help from a metabolic process called ketosis.
How Does the Keto Diet Work?
There are three variations of the keto diet:
Standard keto diet: this is the most common and involves a continuous routine of very low carb, high fat, and moderate protein intake.
Cyclical keto diet: on this variation, you follow the standard keto diet principles but on certain days you switch to higher carb intakes, this is known as “carb loading.”
Targeted keto diet: this approach involves eating carbs up to one hour before exercise with the theory the carbs get used up through your workout.
For the purpose of this guide, I’m going to concentrate on the standard keto diet as this is the most straightforward to start out on.
When on the keto diet, your daily calorie intake should be split into a 4:1 ratio of macronutrients (fat: protein/carbs) which roughly translates into: 2
- Calories from fat: 70 to 80 percent
- Calories from protein: 15 to 25 percent
- Calories from carbs : 5 to 10 percent
This percent split is a general guide just to give you an idea of what you should be aiming for. It’s worth noting the numbers can vary slightly depending on your weight, activity levels, and your targets.
The keto diet is a little different to other conventional diets where the focus is not so much on counting calories, instead you count net carbs.
“What are net carbs?”
The easiest way to explain is by the following equation:
Net Carbs = Total Carbs – Total Fiber
On the keto diet, your goal is to limit net carbs to 50 grams, or preferably lower, per day to reach ketosis.
Don’t worry if this all sounds overwhelming and complicated. You can find some great apps or nutrition calculators around to help you work out your totals.
Even the USDA has a definitive food database which can help get you started. And it won’t take long for it to become second nature. 3
What Can I Eat on the Keto Diet?
When starting out on the keto diet, it can take a little while to get used to what foods you can and can’t eat. Therefore, it’s always best to plan ahead.
Remember to focus on foods that are high in fat, moderate in protein, but most importantly – low in carbs. To make it a little easier for you, here’s a quick round-up of what keto friendly foods you can go for:
- Meat and poultry
- Fish and seafood
- Full-fat dairy
- Natural fats
- Low-carb veggies
- Nuts and seeds
- Healthy fats/oils
- Some low carb fruits
Meat and Poultry
When opting for meat, you pretty much have the green light on what to choose but grass-fed varieties are the best option. The same applies to poultry as carb content is non-existent.
Fish and Seafood
Fatty fish like salmon, tuna, or mackerel are all good sources of fatty acids, protein and low carbs.
Not only are eggs a “go-to” for any dieter, they are also a keto-friendly food you can enjoy.
Full fat Dairy
On a keto diet you need to ditch the low fat yogurts and go full fat. This includes cheese, cream, and butter.
Low Carb Veggies
You have to be careful with your choice of vegetables because some are very high in carbs. Keep to veggies like asparagus, celery, or leafy greens.
Low Carb Fruits
Fruits are another area of caution because many of them contain high levels of sugar. However, there are a few low sugar options – like berries – which are allowed.
Nuts and Seeds
Nuts are a great source of fats, which is why they make the list; however just be cautious which ones you go for. Walnuts, macadamias, and almonds are good choices. Make sure they are in their natural state too and not coated with sugar.
What Can’t I Eat on the Keto Diet?
On the keto diet, there are obviously foods you should avoid like the plague. Step away from anything that contains a lot of sugar or foods that are high in carbs. Here’s a quick rundown of the main offenders:
- Legumes and beans
- Starchy veggies
- Processed foods
- Sugary foods
- Dried and most fresh fruits
- Low fat foods
Anything that’s been made using any type of grain like pasta, rice, bread and even oatmeal is out of the question.
Legumes and Beans
Lentils, chickpeas, and beans need to be banished from the keto diet.Starchy Veggies
Walk away from starchy vegetables like potatoes, yams, or carrots.
Ditch any food that’s been processed. Hotdogs, chips, or junk foods all fall into this category.
Sugar and all things nice don’t cut it on the keto diet. Get rid of candy, desserts, and any baked goods.
Cast to the side any type of drink that has high sugar content; this also means fruits juices.
Most fruit, especially dried fruits like raisins, dates, and banana chips, are not allowed on the keto diet.
Certain alcoholic beverages are laden with sugar, so pass on the cocktails or the beers at the party.
Low Fat Foods
Traditional low fat “diet” foods do not form part of the high fat keto mantra therefore leave well alone.

How to tell when you hit Ketosis?
The keto diet is all about finding the sweet spot of ketosis. However, if it’s a biological process going on inside your body, how can you tell that you’ve hit it?
This is where you have two options.
Being in ketosis means the levels of ketones will be higher in your body than normal. Therefore to get an accurate result – a breath, urine, or blood sample will do the trick.
However, option two is a far simpler.
Your body will also give you natural tell tale signs that you are on target:
- Bad breath 15
- Frequent trips to the bathroom
- Increased thirst
- More energy
- Decrease in appetite
There are people out there who let their state of ketosis take over their diet. To be honest it’s nothing to get hung up over and it’s far better to concentrate your efforts on eating the right foods.
