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.

A quick look at 7 of the best keto apps

What is a keto diet?

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 surrounding research says.

About keto

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:

  • 55–60% fat
  • 30–35% protein
  • 5–10% carbohydrate

For an intake of 2,000 calories per day, 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.

What the research says

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, those who follow a keto diet very strictly may also eat fewer plant foods, which have beneficial properties.

Moreover, some doctors have concerns about the increase in low-density lipoprotein (LDL), or “bad,” cholesterol that these diets cause. In retrospect, this may not be an issue.

A 2020 study stated that there are two sizes of LDL: small-size and large-size, and the total number of small-size LDL is a more potent marker for coronary heart disease.

A 2020 case report shared that it is the small-size or oxidized LDL particles that increase the risk of cardiovascular disease, and not larger LDL particles or the total amount of LDL. Researchers pointed out that the participant, who followed a keto diet, saw a reduction in small and medium-size LDL, and an increase in large-size LDL.

While a doctor following a standard lipid test might recommend abandoning the keto diet, scientists in the case report pointed out that the diet can be very beneficial, especially when people increase their vitamin C intake and reduce the consumption of oxidative polyunsaturated fats.

To prevent oxidation, a person can opt for healthy fat sources, storing them properly, and consuming them before they oxidize or expire.

The above research indicated that doctors who do not yet understand the difference between small-size and large-size LDL in relation to cardiovascular disease may actually be giving the wrong clinical recommendations.

However, more research is necessary to clarify the above with larger and long-term human studies.

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 available studies involve 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 may want to consider reading reviews and looking 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 takes medication, it is important for them to consult a doctor before starting a new diet.
