The LCHF diet is a low-carb, high-fat diet. The Atkins and keto diets are types of LCHF diets. Here are what foods to eat and avoid as well as a sample meal plan for those looking to start the LCHF diet.
Low-carb diets can aid weight loss and are linked to a growing number of health benefits.
A reduced carb intake can positively impact those with various health issues, including type 2 diabetes, IBS, heart disease, autoimmune disease, acne, PCOS and Alzheimer’s disease.
For these reasons, low-carb diets have become popular among those looking to improve their health and lose weight.The low-carb, high-fat eating plan, or LCHF diet, is promoted as a healthy and safe way to lose weight.
The LCHF diet is an umbrella term for eating plans that reduce carbs and increase fats. LCHF diets are low in carbohydrates, high in fats and moderate in protein. This method of eating is sometimes referred to as the “Banting Diet” or simply “Banting” after William Banting, a British man who popularized it after losing a large amount of weight.
The eating plan emphasizes whole, unprocessed foods like fish, eggs, low-carb vegetables and nuts and discourages highly processed, packaged items.
Added sugar and starchy foods like bread, pasta, potatoes and rice are restricted. The LCHF diet doesn’t have clear standards for macronutrient percentages. It’s more of a lifestyle change. Daily carb recommendations on this diet can range from under 20 grams up to 100 grams.However, even those consuming more than 100 grams of carbs per day can follow the diet and be inspired by its principles, as it can be personalized to meet individual needs.
SummaryLCHF diets are low in carbs, high in fats and moderate in protein. The diet can be personalized to meet individual needs.
Is the LCHF Diet the Same as the Keto Diet or Atkins Diet?
The Atkins and ketogenic diets are low-carb diets that fall under the LCHF umbrella.Some types of LCHF diets have set restrictions on the number of carbs you can consume.For example, a standard ketogenic diet typically contains 75% fat, 20% protein and only 5% carbs in order to reach ketosis, a state in which the body switches to burning fats for energy instead of carbohydrates.
To kick-start weight loss, the two-week induction phase for the Atkins diet only allows for 20 grams of carbs per day. After this phase, dieters can slowly add in more carbohydrates.
While these types of low-carb, high-fat diets are more restrictive, anyone can use the LCHF principles without necessarily following specific guidelines. Living an LCHF lifestyle without following predetermined guidelines may benefit those who want flexibility with the number of carbs they can consume.
For example, some people may only find success when they reduce their carb intake to under 50 grams per day, while others may do well consuming 100 grams per day. Since the LCHF diet is adaptable, it may be much easier to follow than more regimented plans like the ketogenic or Atkins diets.
SummaryThe LCHF lifestyle promotes reducing the number of carbs that you consume and replacing them with fats. The ketogenic diet and Atkins diet are types of LCHF diets.
A number of studies have shown that low-carb, high-fat diets are an effective way to promote weight loss. They help people shed pounds by suppressing appetite, improving insulin sensitivity, increasing protein intake and boosting fat loss. LCHF diets have been found to promote fat loss, especially in the belly area. Having too much belly fat, particularly around the organs, can increase the risk of conditions like heart disease, diabetes and certain cancers.
One study found that obese adults who consumed a lower-carb, higher-fat diet for 16 weeks lost more body fat, particularly in the belly area, compared to those following a low-fat diet .
The LCHF diet not only boosts short-term fat loss, it also helps keep weight off for good. A review showed that people who followed very low-carb diets of less than 50 grams of carbs per day achieved significantly greater long-term reductions in weight than people who followed low-fat diets. Another study demonstrated that 88% of participants following a ketogenic diet lost more than 10% of their initial weight and kept it off for one year.
The LCHF diet may be a particularly helpful tool for those whose weight-loss goals are sabotaged by strong cravings for carbohydrates. One study found that participants who followed a very low-carb, high-fat diet had significantly fewer cravings for carbs and starches, compared to participants who followed a low-fat diet. What’s more, participants who followed the very low-carb, high-fat diet had greater reductions in overall reported hunger.
SummaryFollowing an LCHF diet is an effective way to lose body fat, reduce carb cravings and decrease overall hunger.
Cutting carbs and increasing dietary fats can improve health in a number of ways, including promoting weight loss and decreasing body fat.Studies demonstrate that LCHF diets also benefit many health conditions including diabetes, heart disease and neurological conditions like Alzheimer’s disease.
Diabetes
A study of obese adults with type 2 diabetes found that a very low-carb, high-fat diet led to greater improvement in blood sugar control and a more substantial reduction in diabetes medication than a high-carb diet. Another study in obese participants with type 2 diabetes showed that following a ketogenic diet for 24 weeks resulted in significant reductions in blood sugar levels and a decreased need for blood sugar medications. What’s more, some of the participants assigned to the ketogenic diet were able to discontinue their diabetes medications completely.
Neurological Diseases
The ketogenic diet has long been used as a natural treatment for epilepsy, a neurological disorder characterized by recurrent seizures. Studies show that LCHF diets may play a therapeutic role in other neurological diseases, including Alzheimer’s disease. For example, one study demonstrated that a ketogenic diet led to improved cognitive functioning in patients with Alzheimer’s disease.
Plus, diets high in processed carbs and sugar have been linked to an increased risk of cognitive decline, while low-carb, high-fat diets seem to improve cognitive function .
Heart Disease
LCHF diets can help reduce body fat, lower inflammation and improve blood markers related to heart disease. A study in 55 obese adults found that following an LCHF diet for 12 weeks reduced triglycerides, improved HDL cholesterol and decreased levels of C-reactive protein, a marker of inflammation linked to heart disease .
LCHF diets have also been shown to reduce blood pressure, lower blood sugar, decrease LDL cholesterol and promote weight loss, all of which can help reduce the risk of heart disease.
Autoimmune Disease
Recent studies have suggested that a low carb, high protein and moderate fat diet can alter immune responses in patients who have autoimmune diseased. The studies infer that when you have restricted carbohydrates, or just insufficient calories, you will start generating ketone bodies instead of glucose. Your body will be using these ketones for fuel.
A ketogenic diet helps calm down the chronic pain that arises from an
overexcited and overstimulated nervous system. One ketone, called Beta-hydroxybutyrate, blocks the immune system receptors linked to inflammation, and help decrease nervous system activity. A person with irregular auto-immune responses, such as skin conditions, gastrointestinal symptoms, joint and vascular disease, find relief of symptoms when the body produces ketones, as the inflammatory response that causes their diseases to present are often suppressed or eliminated.
SummaryLCHF diets may benefit those with heart disease, diabetes, neurological conditions like epilepsy and Alzheimer’s disease and auto-immune disease like Inflammatory bowel disease (Crohn's disease, ulcerative colitis), Rheumatoid arthritis (RA), Lupus, Multiple sclerosis (MS), Scleroderma, Psoriasis, and Psoriatic arthritis.
When following an LCHF diet, it’s important to reduce your intake of foods high in carbs.
Here is a list of items that should be limited:
- Grains and starches: Breads, baked goods, rice, pasta, cereals, etc.
- Sugary drinks: Soda, juice, sweet tea, smoothies, sports drinks, chocolate milk, etc.
- Sweeteners: Sugar, honey, agave, maple syrup, etc.
- Starchy vegetables: Potatoes, sweet potatoes, winter squash, beets, peas, etc.
- Fruits: should be limited, but consuming small portions of berries is encouraged.
- Alcoholic beverages: Beer, sugary mixed cocktails and wine are high in carbohydrates.
- Low-fat and diet items: Items labeled “diet,” “low-fat” or “light” are often high in sugar.
- Highly processed foods: Limiting packaged foods and increasing whole, unprocessed foods is encouraged.
Although the above foods should be reduced in any LCHF diet, the number of carbs consumed per day varies depending on the type of diet you are following.
For example, a person following a ketogenic diet must be stricter in eliminating carb sources in order to reach ketosis, while someone following a more moderate LCHF diet will have more freedom with their carbohydrate choices.
SummaryFoods high in carbohydrates, such as breads, pastas, starchy vegetables and sweetened beverages, should be restricted when following an LCHF diet plan.
Any type of LCHF diet emphasizes foods that are high in fat and low in carbohydrates.
LCHF-friendly foods include:
- Eggs: Eggs are high in healthy fats and essentially a carb-free food.
- Oils: Olive oil, coconut oil and avocado oil are healthy choices.
- Fish: All fish, but especially those high in fats like salmon, sardines and trout.
- Meats and poultry: Red meat, chicken, venison, turkey, etc.
- Full-fat dairy: Cream, full-fat plain yogurt, butter, cheeses, etc.
- Non-starchy vegetables: Greens, broccoli, cauliflower, peppers, mushrooms, etc.
- Avocados: These high-fat fruits are versatile and delicious.
- Berries: Berries such as blueberries, blackberries, raspberries and strawberries can be enjoyed in moderation.
- Nuts and seeds: Almonds, walnuts, macadamia nuts, pumpkin seeds, etc.
- Condiments: Fresh herbs, pepper, spices, etc.
Adding non-starchy vegetables to most meals and snacks can boost antioxidant and fiber intake, all while adding color and crunch to your plate.
Focusing on whole, fresh ingredients, trying new recipes and planning meals ahead of time can help you stay on track and prevent boredom.

More extreme versions like the ketogenic diet are not suitable for children, teens and women who are pregnant or breastfeeding, unless it’s being used therapeutically to treat a medical condition.
People who have diabetes or health conditions like diseases of the kidneys, liver or pancreas should speak with their doctor before beginning an LCHF diet.
Although some studies show that LCHF diets can boost athletic performance in some cases, it may not be suitable for elite athletes, as it can impair athletic performance at competitive levels .
Additionally, an LCHF diet may not be appropriate for individuals who are hypersensitive to dietary cholesterol, often referred to as “hyper-responders” .
The LCHF diet is generally well tolerated by most but can cause unpleasant side effects in some people, especially in the case of very low-carb diets like the ketogenic diet.
Side effects may include:
- Nausea
- Constipation
- Diarrhea
- Weakness
- Headaches
