The ketogenic (keto) diet is a high-fat, low-carbohydrate, and moderate-protein diet. It involves eating foods such as fish and seafood, meat and poultry, non-starchy vegetables, avocados, berries, nuts and seeds, eggs, high-fat dairy products, olive oil and other oils, and high-cocoa chocolate. While the keto diet allows for a wide variety of tasty and nutritious meals, it restricts several food groups, including starchy foods like pasta, rice, potatoes, bread, corn, peas, beans, and legumes, as well as fruits due to their high carbohydrate content. In addition, the keto diet is associated with an increased intake of saturated fat, which may lead to adverse health effects. Therefore, while the keto diet may offer flexibility within its food groups, it is not a diet where you can eat whatever you want.

What You'll Learn
Keto is a high-fat, low-carb, moderate-protein diet
The ketogenic (keto) diet is a high-fat, low-carbohydrate, and moderate-protein diet. The keto diet is all about cutting carbs and eating more fat, with fat supplying as much as 90% of daily calories. Carbohydrates are the body's preferred source of energy, but on a strict ketogenic diet, about 5% to 10% of energy intake is from carbohydrates. The reduction of carbohydrates puts the body into a metabolic state called ketosis, where the body starts breaking down stored fat into molecules called ketone bodies to use for energy.
On the keto diet, it is important to make sure you get enough fiber. Foods you can eat include fish and seafood, meat and poultry, non-starchy vegetables like broccoli, zucchini, and bell peppers, avocados, berries, nuts and seeds, eggs, high-fat dairy products like cheese, olive oil and other oils, and high-cocoa chocolate. Vegetables are an important part of the diet, and non-starchy vegetables are low in calories and carbs but high in nutrients, including vitamin C and several minerals. Cheese is also a good source of fat and protein, but it is important to limit the amount of saturated fat in your diet.
There are several versions of the ketogenic diet, including the standard ketogenic diet (SKD), which is a very low-carb, moderate-protein, and high-fat diet, typically containing 70% fat, 20% protein, and only 10% carbs. The cyclical ketogenic diet (CKD) involves periods of higher-carb refeeds, such as 5 ketogenic days followed by 2 high-carb days. The targeted ketogenic diet (TKD) allows you to add carbs around workouts. The high-protein ketogenic diet is similar to the SKD but includes more protein, with a ratio of 60% fat, 35% protein, and 5% carbs.
The keto diet can involve a drastic shift in eating and drinking habits. For example, soda is high in sugar and should be avoided, and whole milk is too rich in carbohydrates to be keto-compliant. However, there are many keto-friendly options when eating out. Most restaurants offer meat or fish-based dishes, and you can replace any high-carb food with extra vegetables. Egg-based meals are also a good option, and you can always ask for extra avocado, cheese, bacon, or eggs.

Non-starchy vegetables are a must
The keto diet is a high-fat, very low-carbohydrate, and moderate-protein diet. It is advertised as a weight-loss diet, but it is actually a medical diet that comes with serious risks. It is traditionally used to reduce seizures in children with epilepsy. The keto diet is all about cutting carbs and eating more fat, and vegetables are an important part of the diet.
Non-starchy vegetables are a good source of fiber, which is essential for the health of your gut microbiome. They also help to prevent constipation, a common side effect of the keto diet due to the low fiber intake. In addition to non-starchy vegetables, berries can be eaten in small portions as they are lower in carbs than other fruits.
While the keto diet allows for a lot of high-fat foods, it is important to be mindful of the type of fat consumed. The diet is associated with an increase in "bad" LDL cholesterol, which is linked to heart disease. Therefore, it is recommended to limit saturated fats to no more than 7% of your daily calories. Choose heart-healthy unsaturated fats like nuts, seeds, avocados, tofu, and olive oil.
In conclusion, non-starchy vegetables are a must on the keto diet as they provide essential nutrients, fiber, and antioxidants while keeping carb intake low. They also help prevent some of the negative side effects of the keto diet, such as constipation and nutrient deficiencies.

High-protein foods are allowed in moderation
The ketogenic diet (keto) is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It involves a drastic shift in eating and drinking habits. While on keto, it is important to make sure you get enough fiber.
The keto diet is a high-fat, moderate-protein, and very low-carbohydrate diet. Carbohydrates are the body's preferred source of energy, but on a strict ketogenic diet, about 5% to 10% of energy intake is from carbohydrates. The reduction of carbohydrates puts the body into a metabolic state called ketosis, where the body starts breaking down stored fat into ketone bodies to use for energy. Eating too much protein can interfere with ketosis.
Protein is a part of the keto diet, but it is important to moderate the amount consumed. The current recommended intake for protein averages 46 grams per day for women and 56 grams for men. High-protein foods that are allowed in moderation on the keto diet include fish and seafood, meat, poultry, eggs, and dairy products such as cheese, yogurt, and cottage cheese. These foods are rich in protein and calcium. For example, 7 ounces of plain Greek yogurt provides about 8 grams of carbohydrates and 20 grams of protein, while 8 ounces of cottage cheese has just over 6 grams of carbohydrates and 28 grams of protein.
It is important to note that the keto diet is associated with an increased intake of saturated fats, which can have negative impacts on heart health. Therefore, it is recommended to limit saturated fats to no more than 7% of daily calories and choose heart-healthy fats like avocados, which are high in monounsaturated fat and potassium.

Avoid starchy foods and fruits
The ketogenic diet, or keto, is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It typically contains 70% fat, 20% protein, and only 10% carbs. Carbohydrates are the body's preferred source of energy, but on a strict ketogenic diet, about 5% to 10% of energy intake is from carbohydrates. The reduction of carbohydrates puts the body into a metabolic state called ketosis, where the body uses fat as energy instead of carbohydrates.
While on the keto diet, it is important to avoid starchy foods and fruits, as these are high in carbohydrates. This includes grains, legumes, starchy vegetables, and fruits. Starchy vegetables to avoid include peas and sweet potatoes, which have a higher amount of carbs than other green veggies. Non-starchy vegetables, on the other hand, are low in calories and carbs but high in nutrients like vitamin C and minerals. Good options for non-starchy vegetables are broccoli, cauliflower, green beans, bell peppers, zucchini, and spinach, which have less than 8 grams of net carbs per cup. Net carbs are calculated by subtracting fiber from total carbohydrates.
It is important to note that all fruits are rich in carbohydrates, but some berries can be consumed in small portions. Raspberries, for example, are packed with fiber and have only 1.7 g of net carbs per 1/4 cup. However, bananas should be avoided, especially when aiming to lose weight, as they are high in carbohydrates.
In addition to avoiding starchy foods and fruits, it is important to be mindful of your protein intake while on the keto diet. Eating too much protein can interfere with ketosis. It is recommended to include a variety of healthy fats, such as nuts (almonds, walnuts), seeds, avocados, tofu, olive oil, and high-fat dairy products.

The keto diet has several health risks
The keto diet has gained popularity in recent years, but it is not without its health risks. The ketogenic diet is a low-carb, high-fat, and moderate-protein diet. While it can lead to weight loss and lower blood sugars, it is often unsustainable, and weight gain can return. Here are some of the health risks associated with the keto diet:
Nutrient Deficiencies: The keto diet restricts many nutrient-rich foods, including fruits, vegetables, whole grains, and legumes. This restriction can lead to deficiencies in vitamins, minerals, fiber, and phytochemicals. Specifically, the keto diet may result in a lack of B vitamins and fiber, which are essential for gut health.
Heart Disease: The keto diet encourages the consumption of high amounts of saturated fats, which can increase the risk of heart disease. While there are heart-healthy sources of fat, individuals on the keto diet may not be educated enough to make the right choices and may consume excessive amounts of unhealthy fats.
Kidney Stones and Constipation: The diet can lead to an increased risk of kidney stones and constipation due to the restricted intake of fluids and fiber.
Social Isolation and Disordered Eating: The keto diet is extremely strict and challenging to maintain. It may cause social isolation as it can be difficult to eat out or socialize while adhering to the diet. The restrictive nature of the diet may also lead to disordered eating patterns.
Other Health Risks: The keto diet has been associated with low blood pressure, nutrient deficiencies, and adverse effects in individuals with diabetes. It is not suitable for everyone, and certain populations, such as those with type 1 diabetes, may experience negative outcomes, including frequent hypoglycemic episodes and dyslipidemia.
It is always recommended to consult a healthcare professional or a dietitian before starting any new diet, especially one as restrictive as the keto diet.
