Keto Diet Restrictions: Foods You Should Avoid Eating

The ketogenic diet is a high-fat, low-carbohydrate, and moderate-protein diet. The diet is designed to put the body into a state of nutritional ketosis, where the body burns fat for fuel instead of carbohydrates. While the keto diet can be an effective way to lose weight, it is important to note that it restricts several food groups, including fruits, vegetables, grains, and sweets.

- Starchy vegetables: Potatoes, sweet potatoes, corn, beets

- High-sugar fruits: Bananas, raisins, dates, mangoes, pears

- Bread and baked goods: Rolls, bagels, tortillas, cakes

- Grains and pasta: Rice, oats, couscous, noodles

- Sweeteners and sugary foods: Table sugar, honey, agave, ice cream, sugary cereals

- Carb-rich snack foods: Chips, crackers, granola bars

- Legumes: Black beans, lentils, chickpeas

- Most fruits and fruit juices: Grapes, dried fruit, pineapple, orange juice

- Sweetened drinks: Soda, fruit smoothies, sugary coffee drinks, energy drinks

- Higher-carb alcoholic drinks: Beer, sugary mixed drinks

- Sugary condiments: Ketchup, barbecue sauce, sugary salad dressings

Starchy vegetables (e.g. potatoes, corn, sweet potatoes)

Starchy vegetables like potatoes, corn, and sweet potatoes are not recommended for a keto diet. This is because the keto diet is a high-fat, low-carbohydrate, and moderate-protein diet. The aim is to put your body into a metabolic state called ketosis, where it burns fat for fuel instead of carbohydrates.

Starchy vegetables are high in digestible carbohydrates, which can prevent you from reaching and maintaining ketosis. For example, a medium-sized potato contains 33 grams of net carbs. That's more than the total amount of carbohydrates you should be consuming in a day on a keto diet, which is typically limited to between 20 and 50 grams.

Instead of starchy vegetables, the keto diet recommends non-starchy, low-carb vegetables. These include broccoli, cauliflower, green beans, bell peppers, zucchini, spinach, and summer squash. These vegetables are much lower in carbohydrates, with a cup of broccoli containing only 6 grams of net carbs. They are also high in fibre, vitamins, and minerals, providing essential nutrients while keeping within the strict carbohydrate limits of the keto diet.

Some people find the keto diet challenging due to the severe restriction of carbohydrates. It can be difficult to stick to in the long term, and it may not be suitable for everyone. It is always best to consult a healthcare professional before starting any new diet, especially a restrictive one like keto.

High-sugar fruits (e.g. bananas, raisins, mangoes)

High-sugar fruits are one of the food groups that should be avoided on a keto diet. This is because the keto diet is a very low-carb, high-fat diet that aims to induce a metabolic state called ketosis, where the body burns fat for fuel instead of carbohydrates.

Fruits that are high in sugar include bananas, raisins, mangoes, dates, and pears. For example, a medium-sized banana contains 24 grams of net carbs, which is the total amount of carbohydrates minus the fiber. Similarly, a cup of mango has 22 grams of net carbs. These fruits can cause a spike in blood sugar levels and are therefore not recommended for a keto diet.

However, it is important to note that not all fruits are off-limits on the keto diet. Berries, for instance, are low in carbs and high in fiber, making them a suitable option. Examples of berries that can be included in a keto diet are strawberries, blackberries, raspberries, and blueberries. These berries have a carb count ranging from 3 to 15 grams of net carbs per half a cup or 3.5 ounces.

While the keto diet restricts many food groups, it is important to prioritize nutrient-rich foods to meet daily nutritional needs and prevent potential side effects such as constipation. In addition to berries, avocados and coconuts are also good sources of healthy fats and can be included in a keto diet in moderation.

Bread and baked goods

The ketogenic (keto) diet is a high-fat, low-carbohydrate, and moderate-protein diet. The diet typically restricts carbohydrates to 20-50 grams per day, with 70-80% of total daily calories coming from fat, 10-20% from protein, and 5-10% from carbohydrates.

• Choose low-carb alternatives: There are many low-carb bread options available, such as cloud bread or bread made with almond or coconut flour. These breads typically have a much lower carbohydrate content than traditional bread.
• Use lettuce wraps or collard greens: Instead of using bread, you can wrap your sandwich fillings in large lettuce leaves or collard greens. This is a simple way to enjoy your favourite sandwich fillings without the carbs.
• Make keto-friendly baked goods: There are many recipes available online for keto-friendly muffins, brownies, and cakes. These recipes typically use alternative ingredients, such as almond or coconut flour, and natural sweeteners like stevia or erythritol, to reduce the carbohydrate content.
• Focus on whole foods: Instead of trying to replace bread and baked goods, focus on eating a variety of whole foods that are naturally low in carbs. This includes meat, fish, eggs, vegetables, nuts, and seeds.
• Be mindful of portion sizes: If you do choose to include bread or baked goods in your keto diet, be mindful of the portion sizes. A small amount of bread or a single cookie can fit within your daily carbohydrate limit.

Sugary foods and drinks

Fruit juices and smoothies are also off the menu, as they contain large amounts of fast-digesting carbs that will spike your blood sugar. Instead, stick to water or unsweetened sparkling water as a keto-friendly alternative to soda.

Even some fruits are too high in carbs to include in a keto diet. Avoid bananas, raisins, dates, mangoes, and pears. Berries are a better choice, as they are lower in carbs and high in fiber.

When it comes to drinks, opt for unsweetened coffee and tea. While these are carb-free, be mindful of what you add to them. Avoid "light" coffee and tea lattes, as these are typically made with non-fat milk and high-carb flavourings. Instead, you can add heavy cream to your coffee or tea, but only in moderation.

Legumes (e.g. black beans, lentils, chickpeas)

Legumes, including black beans, lentils, and chickpeas, are not recommended for a keto diet. This is because they are considered high-carb foods, and the keto diet is a very low-carb, high-fat diet.

The keto diet restricts total carbohydrate intake to less than 50 grams per day, and legumes are included in this restricted category. This is because legumes are high in fiber and magnesium, a mineral required for blood pressure regulation and blood sugar control. While these are essential nutrients, they are also high in carbohydrates, which are limited on the keto diet.

Legumes are also part of a heart-healthy diet, but their high-carbohydrate content means they are not suitable for the keto diet. Instead, the keto diet focuses on foods like seafood, meat, poultry, eggs, dairy, nuts, seeds, and non-starchy vegetables.

The keto diet is a challenging diet to follow, and it is important to ensure you are still getting enough fiber, vitamins, and minerals. It is always a good idea to consult a healthcare professional or registered dietitian before starting a new diet like keto.
