Lemons on a Keto Diet: What You Need to Know

The ketogenic diet, or keto diet, is a low-carb, high-fat regime that has gained popularity in recent years due to its potential weight loss and health benefits. 

The diet involves reducing carbohydrate intake and increasing the consumption of healthy fats to promote a state of ketosis, where the body burns fat for energy instead of glucose. 

While the keto diet can be effective for weight loss and other health goals, it can also be restrictive in terms of food choices

For example, you can’t eat potato chips, bananas, or high-carb grains like corn while on keto. But what about lemons?

Known for their tart flavor and as a good source of vitamin C, lemons are a popular ingredient in many recipes and beverages. So, are lemons keto?

Yes, lemons are a low-carb fruit and keto-friendly as long as they’re consumed in moderation. They’re also highly nutritional and rich in antioxidants.

Can You Eat Lemons on a Keto Diet?

Lemons are not only low in grams of net carbs, but they are also low calorie, making them a great addition to a weight loss diet. 

A whole lemon only contains about 17 calories and 5 grams of carbs, which is good news because you don’t have to use a whole lemon in your meal. A small amount of lemon juice or zest can go a long way.

Here’s the nutritional data per 1 whole fruit (60g):

  • 17 calories
  • 1 g protein
  • 5 g total carbs
  • 2 g dietary fiber
  • 3 g net carbs

Break that down even further and see that one tablespoon of lemon juice contains only 1 gram of net carbs, so you don’t have to worry about the amount of carbs you’re consuming from lemon.

Overall, lemons can be a healthy and flavorful addition to a keto and low-carb diet when used in moderation and in combination with other low-carb, high-fat foods.

If you want to consume even less carbs, lemon zest is a great alternative. It adds a tangy lemon flavor, and it’s basically zero-carb.

Lemons are a great source of vitamin C, can support heart health and improve digestive health. They are also low-carb, making them a great addition to a keto diet! Using lemon marinade on chicken can be a great way to support your keto diet and other health goals.

Benefits of Eating Lemons on a Keto Diet

Lemons are not only a tasty addition to many dishes, but they also offer a range of overall health benefits, including:

  • High vitamin C content: Just one lemon provides about 31 mg of vitamin C, which is about 34% of the daily recommended intake for adults.
  • Antioxidant properties: Lemons contain citrus flavonoids and limonoids, which reportedly have anti-inflammatory and anti-cancer properties.
  • Gut health: The soluble fiber pectin in lemons acts as a prebiotic, which nourishes beneficial bacteria in the gut. In turn, it supports a healthy gut microbiome, contributing to better digestive health and overall well-being.

In a keto diet, lemons can be a helpful ingredient in promoting digestive health and supporting the immune system. Here are some ways that lemons can complement a keto diet:

  • Hydration: By adding a squeeze of lemon juice to a glass of cold or warm water, you can create a refreshing lemon water drink that prevents dehydration which may be issue for some people on the keto diet.
  • Antioxidant support: The antioxidants in lemons can help combat the negative effects of oxidative stress and inflammation, which are common side effects of the keto diet.
  • Flavor enhancement: Lemon juice and zest can add flavor to dishes without adding too many net carbs, making them a great ingredient for keto recipes. The bright yellow is also a welcome splash of color.

Furthermore, various animal studies indicate that plant compounds in lemon extract may prevent or reduce weight gain. These studies suggest that lemon or lemon extract could also benefit those looking to manage their body weight or prevent weight gain.
