Following a keto diet can be challenging, but several apps are available to help people track their macronutrients, or macros. Some of these apps also provide suitable recipes and nutritional information for a range of foods.
The features of keto apps vary, and a person’s preference will likely depend on their level of experience with the diet and their specific goals.
In this article, we examine some of the best keto diet apps. We also discuss what a keto diet is and what the research around it says.
A ketogenic, or keto, diet is a low carbohydrate diet that some people use for weight loss or to reduce body fat percentage. The diet is high in fats, moderate in proteins, and very low in carbohydrates. People track these macros with the aim of consuming them in the following ratios:
For a 2,000 calorie per day intake, this would mean consuming 20–50 grams (g) of carbohydrates.
The science behind the approach is to put the body into a state of ketosis.
Glucose is the body’s primary source of energy, and the body will choose this over any other source when it is available. People obtain glucose from carbohydrates in the diet.
When someone eats less than 50 g of carbohydrates per day, the body changes how it sources energy, producing ketone bodies to use as fuel instead. Health experts call this metabolic state ketosis.
In ketosis, the body produces less insulin. As a result, it stores less glucose as fat. In this way, the keto diet can help someone looking to lose weight and body fat.
Experts generally consider it to be safe, because the amount of ketone bodies that the body produces does not alter the blood’s pH levels. This distinguishes ketosis from ketoacidosis — a life threatening condition in which much larger numbers of ketone bodies alter the blood’s pH to make it acidic.

Researchers are still studying keto diets to determine their possible benefits and safety issues.
Some research indicates that keto diets are effective for weight loss. However, many doctors are concerned about the increase in low-density lipoprotein, or “bad,” cholesterol that these diets cause. Those who follow a keto diet very strictly may also eat fewer plant foods, which have beneficial properties.
Other studies suggest that ketone bodies may be beneficial for healthy aging and help treat some chronic conditions, such as Alzheimer’s disease and cancer. However, many studies to date have involved animals, and human research is necessary to make firm conclusions about these potential benefits.
Various keto diet apps are available to cater to people’s differing needs and experiences.
Some apps focus on tracking macros and providing recipes, whereas others allow individuals to track their fitness and get advice from professionals and the keto community.
Some people may find apps that detail net rather than total carbohydrates more useful. They should also read reviews and look at the interface of an app to see whether it can work for them.
A person can also find information about keto diets on other apps and websites, such as YouTube and Reddit. However, not all of this advice will be from professionals who are qualified to educate an individual about nutrition.
If someone has a health condition or uses medication, they should consult a doctor before starting a new diet.
