The ketogenic diet is a high-fat, moderate-protein, and very low-carbohydrate diet. The goal is to reach a metabolic state called ketosis, where the body uses fat instead of carbohydrates as its primary source of energy. To achieve ketosis, it is recommended to limit daily carbohydrate intake to 20-50 grams. As a result, several food groups are restricted on the keto diet. These include fruits, starchy vegetables like potatoes, sweet potatoes, carrots, and peas, grains like wheat, rice, corn, and oats, legumes like beans, and high-carb beverages like beer, liqueurs, and mixed drinks. While some processed meats are keto-friendly, others like glazed ham should be avoided due to their sugar content.
| Characteristics | Values |
|---|---|
| Carbohydrates | To be limited to 20-50 grams per day |
| Starchy foods | Peas, carrots, potatoes, sweet potatoes, corn, legumes, beans, grains, wheat, rice, oats, pasta, crackers, cereal, and bread |

| Fruits | Bananas, grapes, mangoes, and other fruits with high sugar content |

What You'll Learn
Alcoholic drinks
If you want to drink alcohol while on a keto diet, opt for a shot of hard liquor paired with unsweetened soda water. A vodka soda, for example, has zero carbs per drink. However, it's important to note that most alcoholic drinks offer little in terms of micronutrients like vitamins and minerals. Therefore, it's generally recommended to reserve your sparse daily carb allowance for nutrient-rich fruits, vegetables, legumes, and grains instead of alcohol.
Additionally, be cautious when consuming beverages other than alcohol. Whole fruits are preferable to high-carb, low-fiber juices, which can hinder ketosis. Sodas, in particular, are essentially carbonated sugar water that provides zero nutrition and a high carb count. Even a single drink can quickly surpass your daily carb limit. Instead, try drinking 6 to 8 glasses of water per day, and if you want something other than plain water, consider adding flavorings or carbonating your water.

Starchy vegetables
Instead of starchy vegetables, it is recommended to consume non-starchy, low-carb vegetables on the keto diet. These include leafy greens, peppers, broccoli, and cauliflower. Cauliflower, in particular, is a great substitute for starchy foods and can be used as a replacement for mashed potatoes or rice.
It is important to note that the keto diet is not a one-size-fits-all approach, and it can be challenging to follow long-term. Working with a registered dietitian is crucial to ensure that individuals receive essential nutrients while maintaining ketosis and avoiding potential negative health impacts.

Fruits
The keto diet is a restrictive eating plan focused on extremely low carbohydrate consumption. People following the keto diet are instructed to limit carbohydrates to less than 50 grams per day, with some sources suggesting no more than 20 grams daily. This means that fruits, which are typically high in carbohydrates, need to be consumed in moderation as an occasional indulgence.
When it comes to fruits, it is important to look at the number of net carbs per serving, which is calculated by subtracting the amount of fibre from the total grams of carbohydrates. While some fruits are too high in carbs to be included in the keto diet, there are still plenty of low-carb fruits that can be enjoyed. These include avocados, olives, tomatoes, berries, watermelon, cantaloupe, lemons, limes, and coconut.
It is worth noting that while the keto diet can be effective for weight loss and managing certain health conditions, it is not suitable for everyone. It can be potentially harmful to people with certain chronic health conditions, such as those taking insulin for type 2 or type 1 diabetes. It is always recommended to consult a healthcare professional before starting any new dietary regimen.

Legumes
The keto diet is a high-fat, low-carbohydrate diet. The diet aims to transition the body's metabolism into a state called ketosis, where fat becomes the primary source of energy instead of carbohydrates. To achieve ketosis, it is recommended to limit your daily carbohydrate intake to 20-50 grams.
However, some people may choose to include small portions of legumes in their keto diet due to their nutritional benefits. Legumes are a good source of dietary fiber, protein, calcium, and other micronutrients. Processed legumes, such as hummus, can also be included in modest portions.
It is important to note that the keto diet is not a one-size-fits-all approach, and it is always recommended to work with a dietitian to ensure you are getting essential nutrients while maintaining ketosis. Additionally, the keto diet can be challenging to maintain and may not be suitable for everyone.

Grains
The keto diet is distinguished by high fat, modest protein, and very low-carbohydrate intake. The reduction of carbohydrates puts the body into ketosis. The body starts breaking down stored fat into molecules called ketone bodies to use for energy when there is little or no circulating blood sugar from food.
Even whole-wheat pasta and bean-based pasta are high in carbs. A slice of bread has 11 grams of carbs on average, so while you could technically have one slice a day, that would be your entire daily carb allowance. Cereal, crackers, and beer are also high in carbohydrates and should be limited or avoided on a keto diet.
While it is important to avoid grains on a keto diet, it is also crucial to ensure you are getting essential nutrients. Working with a registered dietitian can help you create a plan that ensures you are getting the proper nutrients while maintaining ketosis.
