The keto diet is a high-fat, moderate-protein, and very low-carbohydrate diet. The diet is advertised as a weight-loss wonder, but it is actually a medical diet that comes with serious risks. It is very restrictive, and many find it hard to stick to. The diet is all about cutting carbs and eating more fat, and it is similar to the Atkins diet from the 1970s. The keto diet reduces your total carb intake to less than 50 grams a day. This is the equivalent of a cup of white rice. The keto diet excludes carb-rich foods like grains, beans, fruits, and starchy vegetables. So, if you're thinking about embarking on a ketogenic diet, you'll be avoiding processed grains and sugar, like pizza and muffins.

What You'll Learn

High-carb foods like grains, beans, fruits and starchy vegetables
The keto diet is a low-carbohydrate, high-fat diet. It involves cutting carbs and eating more fat, which means that carb-rich foods like grains, beans, fruits, and starchy vegetables are excluded.
When it comes to grains, even healthy whole grains are often limited or completely off-limits on keto diets. This is because the keto diet often restricts total daily carb intake to less than 50 grams, which doesn't leave much room for grains. Refined grains, such as those that have been heavily processed or refined, are typically higher in net carbs and lower in fiber than whole grains, so they should be avoided. Examples of high-fiber grains that can be enjoyed in moderation on a carb-controlled diet include quinoa and oats. A 1-cup serving of cooked oats contains 23 grams of net carbs, while quinoa has around 34 grams of net carbs per cup. These grains can help reduce the number of carbohydrates your body absorbs and provide other key nutrients.
Beans are another food group that may need to be limited on a keto diet due to their carbohydrate content. While beans are a good source of fiber, healthy fats, and protein, most varieties are too high in carbs for keto. For example, a half-cup of cooked lima beans contains 12 grams of net carbs. However, there are some keto-friendly options, such as green beans, lupin beans, and black soybeans. Additionally, bean substitutes like mushrooms, eggplant, squash, and ground meat can be used in cooking to create keto-friendly versions of favorite bean dishes.
Fruits are typically restricted on keto diets due to their natural sugar content, which contributes to their carbohydrate levels. Fruits that are particularly high in carbs and should be avoided on keto include dried fruits, such as prunes, which have 64 grams of carbs per 100-gram serving. Fruit smoothies and juices are also not recommended, except for those made from lemon and lime. However, some low-carb fruits can be included in a keto diet, such as tomatoes, raspberries, strawberries, blackberries, and star fruit. These fruits have a lower carb count and can be paired with high-fat snacks like nuts or cheese.
Starchy vegetables are generally avoided on keto diets due to their high carbohydrate content. Vegetables with more than 5 grams of carbs per 100 grams of weight are considered starchy. Examples of keto-friendly vegetables that are not starchy include celery, tomatoes, spinach, and mushrooms. It's important to check the carb content of vegetables to ensure they don't take you over your daily carb limit and prevent your body from staying in ketosis, which is crucial for weight loss on a keto diet.

Alcoholic drinks like beer, liqueurs and mixed liquors
Beer is more difficult to fit into a keto diet. Most beers contain too many carbs in a single serving, but there are low-carb "light" beers available that can be consumed occasionally. Similarly, wine is relatively low in carbs, with around 4 grams of carbs per glass, so it can be consumed in moderation. Sweeter wines may contain more carbs, while drier types may contain less.
It is important to note that alcohol can slow down the fat-burning process and potentially hinder weight loss goals. Additionally, the body tends to burn alcohol before anything else, and drinking alcohol can increase your appetite. Therefore, it is recommended to drink in moderation and be mindful of your overall calorie intake.

Condiments like ketchup, BBQ sauce and sweet chilli sauce
Condiments like ketchup, BBQ sauce, and sweet chilli sauce can be included in a keto diet, but only if they are sugar-free or low-carb. Traditional ketchup and BBQ sauce are often high in added sugars and carbohydrates, which can derail a low-carb keto diet. Therefore, it is important to check the labels and opt for sugar-free or low-carb alternatives. For example, G Hughes offers a range of sugar-free and low-carb condiments, including BBQ sauce and ketchup. Other options include Primal Kitchen's keto ketchup and Sweet Baby Ray's BBQ sauce, which are both recommended by keto dieters.
If you prefer to make your own condiments, there are recipes available for homemade keto-friendly ketchup and BBQ sauce. These recipes typically use alternative sweeteners or natural ingredients to reduce the carb content. For instance, a simple keto BBQ sauce can be made with no cooking involved, as described in the book "Keto for Life".
It is worth noting that some people on a keto diet choose to avoid low-sugar ketchup because it is sweetened with sucralose. However, this is not a deal-breaker for everyone, especially if the ketchup has a low carb count per serving.
In general, when choosing condiments for a keto diet, it is important to prioritize low-carb options, avoid hidden sugars, and opt for simple, natural ingredients. By doing so, you can enhance the flavour of your meals while staying on track with your keto diet.

Processed grains and sugar like pizza and muffins
The keto diet is a popular, extremely low-carb, high-fat diet. The diet is restrictive, and people on it are often at risk of deficiencies in essential nutrients. Therefore, it is important to be mindful of what you eat and drink.
Processed grains and sugars, such as pizza and muffins, are generally not considered keto-friendly. This is because grains are naturally high in carbs, and processing can add to their carb content. For example, a single serving of most grains can meet or exceed your entire carb allotment for the day. Wheat, barley, and rye also contain gluten, which many people are sensitive to.
However, some people on a less strict low-carb keto diet may be able to include some grains in moderation. For example, popcorn is a grain that can be relatively easily incorporated into a keto diet, as long as you avoid toppings with added sugar. Similarly, some people might be able to include a slice of Ezekiel bread, a sprouted ancient grain bread, in their keto diet.
Grains that are less processed and refined tend to have a lower carb content. For example, whole grains in their most minimally processed form are often the richest in fiber and nutrients and the lowest in net carbs. Therefore, it is generally recommended to choose unprocessed whole grains and be mindful of serving sizes.

Starchy vegetables like carrots and peas
Starchy vegetables like carrots, peas, and corn are generally not recommended for a keto diet due to their high carbohydrate content. The keto diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. This shift in metabolism can lead to weight loss and blood sugar regulation.
Carrots, while nutritious, are considered too starchy for keto. A single carrot contains around 7 grams of net carbs, and consuming more than one in a sitting can easily exceed the recommended carb limit for keto, which is typically around 20 to 50 grams of net carbs per day.
Peas are another starchy vegetable to avoid on keto. They are legumes that grow above the ground but are surprisingly high in carbs. Half a cup of peas contains approximately 8.1 grams of net carbs, which is significantly higher than the carb content of other green vegetables.
Corn, a staple in many diets, is also not recommended for keto. It is a grain that falls into the category of starchy vegetables with a high carbohydrate content. One corn-on-the-cob contains about 19.5 grams of net carbs, which is well above the acceptable range for keto.
When following a keto diet, it is essential to be mindful of the carbohydrate content of the foods you consume. Starchy vegetables, like carrots, peas, and corn, can quickly tip you over your daily carb limit and hinder your ability to maintain ketosis. However, this doesn't mean that you have to eliminate all starchy vegetables from your diet. Moderation is key, and you can still include small amounts of these vegetables while staying within your carb allotment. Additionally, you can opt for non-starchy vegetables, such as leafy greens and cruciferous vegetables, which are considered keto-friendly and provide a good source of fiber to help manage any constipation that may arise as a side effect of the keto diet.
