Increasing Carb Intake On Keto: How Many Carbs Are Safe?

The ketogenic diet is a high-fat, moderate protein, and low-carb diet. The recommended daily carb intake varies from 20 to 50 grams, but the ideal amount depends on individual factors such as body weight, metabolic efficiency, and activity level. Staying within this low-carb range helps the body achieve ketosis, a state where fat is used as the primary energy source instead of glucose from carbohydrates. However, a sudden increase in carbs after following a ketogenic diet can be detrimental, and it is recommended to gradually transition off the keto diet to avoid negative symptoms.

The ideal carb intake depends on factors like calorie goal, body weight, metabolic efficiency, and activity level

The keto diet is a high-fat, moderate protein, and low-carb diet. The goal is to reach ketosis, a state where the body uses fat as its primary energy source instead of glucose from carbohydrates. While the general recommendation is to consume less than 50 grams of carbohydrates per day, the ideal carb intake depends on several factors:

Calorie Goal

The number of calories you need each day is determined by your body weight and activity level. The more calories you consume, the more carbohydrates you can include in your diet. For example, if you require 1,200 calories daily, your carb intake should be around 15 grams to stay under the 5% threshold. However, if you consume 2,500 calories, you can increase your carb intake to around 31 grams while still meeting the keto guidelines.

Body Weight

Your body weight influences your calorie needs, and by extension, your carb intake. The heavier you are, the more calories you need to fuel your body. This means that your carb threshold will be higher compared to someone with a lower body weight.

Metabolic Efficiency

Your body's ability to utilise different energy sources also plays a role in determining your ideal carb intake. If you have previously followed a high-carb diet, you may find it challenging to adjust to a ketogenic diet as your body has been accustomed to using glucose as its primary fuel source. On the other hand, if you have experience with moderate or low-carb diets, the transition to keto may be more manageable.

Activity Level

Your activity level and the type of exercise you engage in regularly can impact your carb intake. If you lead a sedentary lifestyle and are overweight, it is recommended to keep your carb intake on the lower end to ensure you achieve ketosis. In contrast, if you are very active and exercise 4-5 times a week, you may be able to consume more carbohydrates while still maintaining ketosis. Additionally, high-intensity training can deplete glycogen stores, which may allow for a slight increase in carb intake around workout sessions without disrupting ketosis.

The keto diet recommends less than 5% of calories from carbs, which is roughly 20 grams of carbs per day

The keto diet is a high-fat, moderate protein, and low-carb diet. The ketogenic diet recommends keeping your carbohydrate intake extremely low – less than 5% of your calories from carbs, which is roughly 20 grams of carbs per day. This is because the body achieves ketosis, the goal of going keto, by limiting carbs and using fat as the primary energy source instead of glucose from carbohydrates.

The number of carbs you can have on keto depends on your overall calorie goal, body weight, metabolic efficiency, and activity level. The more calories you can eat, the more carbohydrates you can eat, and vice versa. The more you weigh and the more active you are, the more energy you need to fuel your body. For a standard ketogenic meal plan, carbs should make up less than 5% of your energy intake. This equates to 15 grams of carbs a day for someone who needs 1,200 calories a day, and 31 grams per day for someone eating 2,500 calories a day.

It is important to note that the number of carbs you can have on keto also depends on your body and how long you've been on the keto diet. Some people can easily get into ketosis and stay there with 50 grams of total carbs per day, while others need to stay at around 20 grams of total carbs per day. It is recommended that beginners stick to 20 grams of net carbs per day or 20 grams of total carbs for therapeutic purposes. Net carbs are the total carbs minus fibre and sugar alcohols.

You can determine if you are in ketosis by regularly testing your blood using a blood-ketone testing meter. Other signs that you are in ketosis include increased energy, decreased sugar cravings, and the ability to go longer between meals.

Net carbs are the total carbs minus fibre and sugar alcohols

Net carbs are calculated by subtracting the fibre and sugar alcohol content from the total number of carbohydrates in a food product.

Net carbs = Total Carbohydrates - Fibre - Sugar Alcohols

Fibre is a type of carbohydrate that is not absorbed in the small intestine. Instead, it passes directly into the colon and provides no calories. It also has no effect on blood sugar or insulin levels. Sugar alcohols are processed similarly to fibre, and they are only partially absorbed into the small intestine. They have a minimal effect on blood sugar and insulin levels.

The calculation of net carbs is important for those on the keto diet, as it helps them monitor their carbohydrate intake. The keto diet recommends keeping carbohydrate intake very low, at less than 50 grams per day, to achieve and maintain ketogenesis. However, the threshold for ketogenesis varies from person to person, and some may find they need to restrict their intake further. Net carbs can help those on the keto diet make informed food choices while still enjoying some sweet treats in moderation.

It is important to note that the calculation of net carbs is not an exact formula and is controversial within the nutrition community. The Food and Drug Administration (FDA) does not recognise the term "net carbs" and instead recommends using the total carbohydrates listed on nutrition labels.

To achieve ketosis, most guidelines recommend 15-30 grams of net carbs per day

When starting a keto diet, it is recommended to stick to 20 grams of net carbs per day for the first three months. This amount is likely to get almost everyone into ketosis. After this period, you can start to increase your net carbs by 5 grams every three days, testing your ketone levels to ensure you remain in ketosis.

The number of carbs you can eat on keto also depends on your daily calorie intake. For example, if you need 1,200 calories a day, your carb threshold would be 60 calories from carbs, or 15 grams of carbs. If you eat 2,500 calories a day, you could eat 31 grams of carbs and still be in ketosis.

It's important to note that keto is not meant to be a zero-carb diet, and some people can get away with eating more carbs and still stay in ketosis. Additionally, if you are very active and exercise regularly, you are more likely to be able to consume more carbs and stay in ketosis.

You can increase carb intake by eating complex carbs from vegetables or low-glycemic fruits

It is possible to increase your carb intake while on a keto diet, and one way to do this is by consuming complex carbs from vegetables or low-glycemic fruits. Complex carbohydrates are commonly found in whole grains, fruits, vegetables, and legumes. They provide a more nutritious option compared to simple carbs, which are found in sugary items like soda, baked goods, fruit juices, white bread, white pasta, and white rice.

Complex carbs are digested more slowly, avoiding the blood sugar spikes associated with simple carbs. They are also more likely to provide a steady supply of energy and keep you feeling fuller for longer. Additionally, they deliver vitamins, minerals, and fiber that are essential for your health.

Vegetables:

• Avocados: Avocados are a staple for anyone on a ketogenic diet. They are high in essential vitamins and minerals, such as potassium and magnesium, and are a great source of monounsaturated fat. One avocado contains about 2-3g of net carbs per serving.
• Non-starchy veggies: These include vegetables that grow above the ground and tend to be low in starch and carbohydrates. They are also high in fiber, which doesn't count toward your carbohydrate limits as it doesn't break down into glucose. Examples include zucchini, spinach, cucumbers, and broccoli.
• Cauliflower: Cauliflower is a versatile vegetable that can be used as a substitute for starches like rice and potatoes. It contains only 2g of net carbs per cup.
• Olives: Olives are a great carb source on keto, with half of their carbs coming from fiber. A serving of 14 olives contains only 1g of total carbohydrates.
• Brussels sprouts: These veggies are high in fiber, with 8 grams per cup, helping to balance out their carb count.
• Butternut squash: Butternut squash is starchy but relatively low in calories, making it a great swap for more calorie-dense potatoes and sweet potatoes. It's also high in vitamin E, promoting healthy skin.
• Sweet potatoes: Sweet potatoes have a slow-release sugar, thanks to their fiber content. They are also high in vitamin C and beta carotene, which is linked to a reduced risk of heart disease and certain cancers.

Low-glycemic fruits:

• Berries: Berries are an exception to the rule that most fruits are too high in carbohydrates. They are low in carbs and high in fiber and antioxidants, which provide anti-inflammatory effects and protect against disease. Examples include strawberries, blueberries, and raspberries.
• Apples: Apples are a good source of fiber and have a low glycemic index value, causing blood sugar to rise more slowly than other fruits.
• Grapefruit: Grapefruit is another low-glycemic fruit that is an excellent source of vitamin C.
• Oranges: Oranges have a low GI value and are less likely to increase your blood sugar than orange juice.
• Cherries: Cherries are high in potassium and antioxidants and have a low GI value.
• Pears: Pears are high in fiber and have a low GI value, making them a healthy option.

Remember, even when choosing complex carbs or low-glycemic fruits, it's important to monitor your overall carbohydrate intake and adjust it according to your activity level and weight loss goals.
