Lazy keto is a popular variation of the very-low-carb ketogenic, or keto, diet.
It’s often used for weight loss, and, as the name suggests, it’s designed to be easy to follow.
The classic ketogenic diet involves carefully calculating your intake of calories, carbs, fat, and protein to achieve ketosis, a metabolic state in which your body burns mostly fat (1Trusted Source).
However, lazy keto is far less strict, as you only have to pay attention to your carb intake.
This article explains lazy keto, including its benefits, downsides, and foods to eat and avoid.
Lazy keto is a less restrictive version of the traditional high-fat, very-low-carb ketogenic diet.
The ketogenic diet originated in the 1920s as a medical approach to treating epilepsy. Recently, variations of this diet, including lazy keto, have become mainstream strategies for weight loss (2Trusted Source, 3Trusted Source).
Traditional keto diets require you to closely track your macronutrient intake and follow a strict, very-low-carb, high-fat eating pattern that includes only moderate amounts of protein (4Trusted Source, 5Trusted Source).
The intention is to induce ketosis, a metabolic state in which your body burns fat as its primary source of fuel (6Trusted Source).
Like most variations of the ketogenic diet, lazy keto dramatically restricts your carb intake. Typically, carbs are restricted to around 5–10% of your total daily calories — or around 20–50 grams per day for most people (7Trusted Source).
However, you don’t have to worry about tracking calories, protein, or fat on lazy keto.
Studies on various versions of the ketogenic diet suggest that they may offer many potential benefits, though lazy keto has not been studied specifically.
For example, several studies suggest that keto diets may aid weight loss, potentially even more so than low-fat diets (8Trusted Source, 9Trusted Source, 10Trusted Source).
However, this effect is probably not unique to keto diets. Studies show that any diet that reduces calorie intake and is followed long term will likely lead to weight loss over time (11Trusted Source, 12Trusted Source, 13Trusted Source).
Even though lazy keto doesn’t have any rules about calorie restriction, studies suggest keto diets may suppress appetite and food cravings. This may make it easier to reduce your calorie intake without feeling hungry (14Trusted Source, 15Trusted Source).
Additionally, research suggests that keto diets may help improve blood sugar control in those with type 2 diabetes and reduce risk factors for heart disease (16Trusted Source, 17Trusted Source, 18Trusted Source).
However, findings are mixed, and the lazy keto diet has not been studied specifically.
Keep in mind that the beneficial effects of keto diets are often attributed to being in ketosis.
Studies ensure that this metabolic state is achieved by monitoring participants’ diets very closely, as well as by measuring their levels of ketones, which are compounds produced by your body when ketosis is reached and maintained (1Trusted Source).
Since tracking your calories, protein, and fat intake and measuring ketones isn’t required on lazy keto, dieters can’t know whether they’re truly in ketosis.
