The ketogenic diet, commonly known as keto, has become an increasingly popular way to lose weight and improve health in recent years. This very low-carb, high-fat diet puts the body into a metabolic state called ketosis, which has been shown to have many benefits. However, when starting a new diet, it can be confusing to figure out which foods to eat and which to avoid. One food that often comes up in keto discussions is the cucumber. So, is a cucumber good for keto?
What is Keto?
The ketogenic diet typically limits carbs to 20-50 grams per day. This very low level of carbohydrate intake helps transition the body’s preferred fuel source from carbs to fat. Specifically, the liver begins converting fat into fatty acids and ketone bodies through a process called ketogenesis. These ketones can then be used as an alternative energy source in place of glucose from carbs.
When following a keto diet, it’s important to choose foods that are low in carbohydrates and high in fat. Protein intake should be moderate. This macronutrient ratio puts the body into ketosis, which has been found to have many potential benefits for health, weight loss, and performance.
Benefits of Keto
Here are some of the evidence-based benefits that may be achieved by following a well-formulated ketogenic diet:
– Weight loss – Several studies show that people on keto tend to lose more weight and body fat compared to those on high-carb diets. Increased fat burning and reduced appetite are possible reasons for this.
– Improved insulin sensitivity – Ketosis has been shown to lower insulin levels and improve insulin resistance in people with type 2 diabetes and prediabetes. This could protect against complications like kidney disease.
– Reduction in acne – Some research indicates that the high fat, low carb keto diet may help improve acne due to effects on insulin and hormones.
– Neuroprotective effects – The ketones produced during ketosis provide an alternative fuel source for the brain and may have therapeutic effects for neurological disorders like Alzheimer’s and Parkinson’s.
– Anti-cancer potential – Several studies suggest ketosis may inhibit tumor growth and enhance conventional cancer treatments like chemotherapy and radiation therapy.
– Increased mental focus and clarity – People often report improved focus, clearer thinking and enhanced mood while in ketosis. Ketones may provide an efficient energy source for the brain.
What are the Macronutrient Ratios?
To achieve the state of ketosis, the general recommended macronutrient ratio on a keto diet is:
– 60-75% of calories from fat
– 15-30% of calories from protein
– 5-10% of calories from carbs
However, you don’t necessarily need to hit these exact numbers. The level of carb restriction needed to induce ketosis can vary from person to person. Many keto dieters stay under 50 grams of net carbs, while extreme ketogenic diets may limit carbs to as little as 20 grams per day.
The important takeaway is this: keeping carbs low and protein moderate while emphasizing healthy fats will boost ketone production and help you reap the benefits of ketosis.
Keto Food List: What to Eat and Avoid
Here are some of the basic food groups to focus on or limit while following a ketogenic diet:

Are Cucumbers Keto-Friendly?
So now that we’ve covered the basics of keto, let’s get back to the original question: are cucumbers keto? The short answer is yes!
Cucumbers are low in carbohydrates and can fit into a ketogenic diet. One cup of chopped, raw cucumber contains around 3 grams of net carbs (total carbs minus fiber).
For comparison, here are the net carb counts for 1 cup servings of other common low-carb veggies:
– Bell peppers: 5 grams
– Broccoli: 6 grams
– Cauliflower: 5 grams
– Kale: 1 gram
– Lettuce: 1 gram
– Spinach: 1 gram
As you can see, cucumber is on the lower end of the carb spectrum compared to many other keto-approved vegetables.
The fiber and water content are other factors that make cucumbers a good choice for keto. One cup of cucumber slices provides about 1 gram of fiber. Plus, cucumbers are 95% water, making them an ultra hydrating, low-calorie food.
Nutritional Profile of Cucumbers
Here is the full nutritional breakdown for 1 cup of raw, chopped cucumber (104 grams) according to the USDA:
– Calories: 16
– Protein: 0.7 grams
– Fat: 0.1 grams
– Carbohydrates: 3.8 grams
– Fiber: 0.9 grams
– Sugars: 1.7 grams
– Net carbs: 3 grams
– Vitamin K: 62% DV
– Vitamin C: 13% DV
– Magnesium: 8% DV
– Potassium: 9% DV
As you can see, cucumbers provide a variety of important vitamins, minerals and antioxidants like vitamin K, vitamin C, magnesium and potassium. The water content also makes them naturally hydrating.
Benefits of Cucumbers for Keto
Here are some of the reasons why cucumbers can be a healthy addition to a ketogenic diet:
1. Low Carb and Low Calorie
With only 3 net grams of carbs and 16 calories per cup, cucumber is a keto-friendly food that can help you stay under your daily carb limit. The low calorie count can also help with weight loss on keto.
2. Provides Fiber
Getting adequate fiber is important on keto to support digestive health, maintain gut microbiota and help keep you feeling full. Just one cup of cucumber slices provides 5% of the recommended daily fiber intake.
3. Helps Hydration
Proper hydration is crucial on a ketogenic diet, yet drinking enough water can be challenging. Eating hydrating foods like cucumbers that are high in water content helps increase daily fluid intake.
4. Provides Nutrients
In addition to being low carb, cucumbers contain beneficial vitamins, minerals and antioxidants. This makes them a nutritious vegetable choice while on a keto diet.
5. Vegetables Help Balance Keto Diet
Some people focus too heavily on high fat meats and dairy when following keto. Adding low-carb vegetables like cucumbers helps create more balanced nutrition for better overall health.
Tips for Eating Cucumbers on Keto
Here are some simple ways to incorporate cucumbers into your ketogenic diet:
– Make cucumber salad – Toss chopped cucumbers with olive oil, lime juice, salt, and pepper for a quick salad. Consider adding onions, tomatoes or avocado.
– Use cucumber slices as vessels – Spoon tuna, egg, chicken, or ham salad onto cucumber slices for an easy keto meal or snack.
– Add crunch to wraps or lettuce tacos – Cut cucumbers into sticks to add satisfying crunch and moisture to lettuce wraps or low carb tacos.
– Make quick pickles – Mix sliced cucumbers with apple cider vinegar, salt, garlic and dill. Enjoy as a tangy low-carb topping for burgers or tacos.
– Blend into smoothies – Add some cucumber slices into your keto-friendly smoothies made with almond milk and low glycemic berries.
– Use in place of higher carb veggies – Try using thinly sliced cucumbers instead of tomatoes on sandwiches, tacos, or burgers to cut the carbs.
– Make cucumber water – Infuse water with sliced cucumbers, lemons and mint for refreshing, hydrating keto water.
Potential Downsides of Cucumbers on Keto
Although cucumbers are considered a low glycemic vegetable, there are a couple things to keep in mind:
– Cucumber skin may be hard to digest for some – The waxy skin on cucumbers contains insoluble fiber that can cause gas or bloating issues in sensitive people. Peeling the skin can help.
– Higher carb varieties – There are a few types of cucumbers that are higher in carbs, like lemon cucumbers. Check labels and aim for 3-4 grams net carbs per serving.
– Can be high potassium if overeaten – Cucumbers are moderate in potassium, which is usually beneficial but could potentially contribute to elevated potassium levels if eaten in very high amounts.
– May be given a “moderate” rating on some keto food lists – A few keto experts assign cucumber a yellow “moderate” rating due to the potential carb count, so intake should be limited if following strict keto.
Overall though, these issues are easily avoided by consuming cucumbers in moderation as part of a well-formulated ketogenic diet. A 1 cup serving per day is considered safe for most people.
