The keto diet is a high-fat, low-carbohydrate diet that aims to switch the body's primary fuel source from glucose to ketones. It has gained popularity in recent years due to its potential benefits for weight loss, blood sugar control, and cholesterol levels, but may have potential health risks and should be done under the guidance of a healthcare professional.
What is the keto diet?
The ketogenic diet (often called "keto" for short) is a high-fat, low-carbohydrate diet that has gained popularity in recent years. The goal of the diet is to switch the body's primary fuel source from glucose (which comes from carbohydrates) to ketones (which come from the breakdown of fats in the liver).
The keto diet typically involves reducing carbohydrate intake to less than 50 grams per day (sometimes even less than 20 grams per day), while increasing fat intake to make up the majority of daily calories. Protein intake is typically moderate, with the goal of preventing muscle loss.
When the body doesn't have enough carbohydrates to use for energy, it begins to break down fat into ketones, which can then be used as fuel for the body and brain. This process is called ketosis, and it is the hallmark of the keto diet.
What are the health considerations with the keto diet?
The keto diet may have some potential health benefits, such as weight loss, improved blood sugar control, and improved cholesterol levels. However, it's important to consider the potential health risks and side effects associated with the diet as well. Some potential health considerations of the keto diet include:
- Nutrient deficiencies: Since the keto diet restricts many food groups, such as fruits, grains, and some vegetables, it can be difficult to get all the necessary nutrients the body needs. This may increase the risk of nutrient deficiencies, such as vitamin C, vitamin D, and fiber.
- Increased risk of heart disease: Although the keto diet may improve cholesterol levels in the short term, some research suggests that it may increase the risk of heart disease in the long term due to the high amount of saturated fats consumed.
- Increased risk of kidney stones: The keto diet may increase the risk of kidney stones due to the high amount of protein consumed, which can increase the levels of calcium and uric acid in the urine.
- Keto flu: Some people may experience flu-like symptoms, such as headache, fatigue, and nausea, when starting the keto diet. These symptoms usually go away after a few days, but they can be unpleasant.
- Bad breath: One side effect of the keto diet is bad breath, which is caused by the breakdown of ketones in the body.
- Limited food choices: The keto diet can be challenging to follow long-term due to its restrictive nature. It may be difficult to eat out or find suitable options when traveling.
It's important to consult with a healthcare professional before starting the keto diet, especially if you have any underlying health conditions or are taking medications. They can help you determine if the diet is appropriate for you and provide guidance on how to follow it safely.
How can a dietitian help determine if a keto diet is right for you?
A registered dietitian (RD) can play a crucial role in helping you determine if a keto diet is right for you. RDs are trained professionals who specialize in nutrition and can provide personalized advice on how to eat for your specific health needs and goals.
Here are some ways an RD can help you determine if a keto diet is right for you:
- Assessing your health status: An RD can review your medical history, lab work, and other health data to determine if the keto diet is appropriate for you. They can identify any potential risks or concerns and provide guidance on how to address them.
- Evaluating your dietary habits: An RD can review your current dietary habits to determine if the keto diet is a good fit for your lifestyle and preferences. They can provide guidance on how to make the transition to a keto diet and how to ensure that you are getting all the nutrients your body needs.
- Providing personalized recommendations: An RD can provide personalized recommendations on a diet that is tailored to your specific health needs and goals. They can provide guidance on the types of foods to eat, portion sizes, and meal planning.
- Monitoring your progress: An RD can monitor your progress and make adjustments as needed. They can provide ongoing support and guidance to help you stay on track and achieve your goals.
- Providing education and resources: An RD can provide education and resources on the keto diet, including information on the potential health benefits and risks, how to read food labels, and how to make healthy food choices if following the diet.
Overall, working with an RD can help you make informed decisions about whether the keto diet is right for you and how to follow the diet safely and effectively.
