If you find yourself in a conversation about weight loss diets, chances are you’ll hear about the keto diet or the keto diet. The keto diet has become one of the most popular methods around the world among people who want to lose weight and improve their health.

Some studies suggest that a low-carb, high-fat diet may promote fat loss and improve glycemic control in people with diabetes tipo 2. (1) (2)

The keto diet may also have neuroprotective effects and help improve cognitive function in people with Alzheimer’s disease, although more research is needed. (3) (4)

Although the keto diet seems to have some benefits, it is generally high in saturated fat. This can raise LDL (“bad”) cholesterol in some individuals, which can increase the risk of cardiovascular disease and cardiovascular events such as heart attack and stroke. (5) (6)

Because of this, the keto diet may not be a good choice for everyone.

In addition, the keto diet is not recommended for pregnant and lactating mothers and those with kidney disease, liver disease, respiratory failure, cardiac arrhythmia, or type 1 diabetes. (7) (8)

If you’ve been thinking about trying the keto diet and have been cleared by your doctor, use this article to learn more about what to eat and what to limit while on the keto diet.

Keto Diet Basics

The keto diet is generally very low in los hidratos de carbono, high in fat, and moderate in protein.

In the keto diet, carbohydrates make up between 5-10% of the calories consumed, although there are lighter versions of the diet.

Fats should replace most of the reduced carbohydrates and provide about 60-80% of total caloric intake.

Protein should cover about 10-30% of energy needs, while carbohydrates are usually limited to 5%.

This reduction in carbohydrates forces your body to rely on fat as its primary energy source instead of glucose, a process known as ketosis.

While in ketosis, your body uses ketones—molecules made in the liver from fat when glucose is restricted—as an alternative fuel source. Additionally, keto diets reduce hunger and increase satiety, which can be especially helpful when you’re trying to lose weight. (9)

Research shows that keto diets are effective at promoting weight loss—although they may not be more effective than other weight loss diets.

Ketogenic diet meal plan

Following a keto diet may seem like a chore, but it doesn’t have to be difficult. Focus on reducing carbohydrates while increasing the fat and protein content of your meals.

In order to reach and stay in a state of ketosis, carbohydrates must be restricted. While some people can achieve ketosis by consuming as little as 20 grams of carbs per day, others can find success with higher carb intake.

In general, the lower your carb intake, the easier it is to reach and stay in ketosis.
