The ketogenic diet, or keto diet for short, is a low-carb, high-fat diet that has been shown to help some people lose weight. But how does it work, and is it right for you?
First, let’s start by understanding how the body uses food for energy. When you eat carbohydrates, your body breaks them down into glucose, which is then used for energy. However, if you eat more carbs than your body needs, the excess glucose is stored as fat.
On the other hand, when you eat a high-fat, low-carb diet, your body enters a state of ketosis. In this state, it starts using stored fat as its primary source of energy instead of glucose. This is why a keto diet can help you lose weight.
To enter ketosis, you need to significantly reduce your carbohydrate intake and increase your fat intake. The exact ratio of carbs, fat, and protein will depend on your individual needs, but a typical keto diet consists of 75% fat, 20% protein, and 5% carbs.
It’s important to note that a keto diet is not the same as a high-protein diet. While both diets may help you lose weight, a keto diet focuses on burning fat for energy, while a high-protein diet focuses on building muscle.
So, how do you follow a keto diet? The first step is to calculate your macronutrient needs based on your age, gender, weight, and activity level. Then, you’ll need to adjust your diet to meet these needs by eating foods that are high in fat and low in carbs.
Some examples of high-fat, low-carb foods that you can eat on a keto diet include:
- Meat: beef, pork, lamb, chicken, turkey
- Fish and seafood: salmon, trout, shrimp, shellfish
- Eggs: whole eggs, hard-boiled eggs, omelettes
- Dairy: cheese, cream, butter
- Nuts and seeds: almonds, walnuts, chia seeds, flax seeds
- Oils: olive oil, coconut oil, avocado oil

You’ll also want to avoid or limit foods that are high in carbs, such as bread, pasta, rice, and sugary snacks. Instead, opt for low-carb vegetables like spinach, kale, broccoli, and cauliflower. It’s worth noting that a keto diet may not be suitable for everyone. Some people may experience side effects such as the “keto flu,” which can include symptoms like dizziness, and fatigue. If you have a medical condition or are taking certain medications, it’s important to talk to your doctor before starting a keto diet.
So, is a keto diet right for you? If you’re looking to lose weight and are willing to commit to a high-fat, low-carb diet, it may be worth giving it a try. Just be sure to consult with a healthcare professional before making any significant changes to your diet.
In conclusion, a keto diet works by causing your body to enter a state of ketosis, where it begins using stored fat as its primary source of energy instead of glucose. While it can be effective for weight loss, it may not be suitable for everyone and it’s important to consult with a healthcare professional before starting a keto diet.
