What Is Precision Nutrition?

Precision Nutrition (PN) is a dietary philosophy which emphasizes the importance of micronutrient ratios over total calories consumed. A common misconception is that it’s all about counting macros, but that isn’t necessarily true either. In fact, there are many different approaches to nutrition and nutritional science. Some approaches emphasize macronutrients like protein, carbs or fat while others focus on micronutrients such as vitamins and minerals. PN is based on micronutrient ratios rather than total calorie intake.

The idea behind PN is that your body needs certain nutrients at specific levels in order to function properly. For example, if you’re deficient in vitamin D, then you won’t be able to build strong bones and will have a higher risk of developing osteoporosis later in life. If you’re deficient in calcium, your teeth may become porous and weak which could lead to tooth decay. By focusing on micronutrient ratios instead of total calorie intake, you’ll likely get better health results with less effort.

How Does Precision Nutrition Work?

In general, PN involves following a variety of diets to achieve optimal health outcomes. These diets vary from person to person depending on their individual preferences and goals. One approach is known as the “dietary intervention” (DI). A DI is a 6-week program that can be used to assess an individual’s micronutrient intake. From this assessment, the person will learn which foods they should eat more or less of in order to achieve better health.

People who participate in a DI typically follow one of two different programs: the balanced diet and the elimination diet. The balanced diet involves eating a wide variety of foods while the elimination diet involves cutting out problem foods for 2-3 weeks at a time. For example, someone who participates in the balanced diet might add more nuts, seeds, fruits and vegetables to their diet. Someone who participates in the elimination diet might cut out wheat, gluten, dairy and egg for a couple of weeks to see if they notice any improvements.

After the 6-week program is finished, you can use your personalized eating plan to guide your future food choices.

Who Is PN For?

Precision nutrition is intended for people that want to improve their health and wellbeing. However, this approach may not be right for everyone. If someone has a medical condition like diabetes, they should consult their physician before starting a DI program. It’s also a good idea to speak with a health care professional before making any significant dietary changes.

Precision nutrition is a fairly new approach and is not widely available. People interested in this program should speak with their doctor or look for a local provider online.

What Are the Benefits of PN?

Many of the people that use PN report seeing significant improvements in their energy levels, brain function and digestive health. Many people report losing weight without cutting calories or increasing their exercise routine. One of the main benefits of PN is that it can be tailored to your individual needs, which makes it more likely for you to achieve long-term success.

What Are the Drawbacks of PN?

PN is not suitable for everyone, especially those with certain medical conditions. It’s also not suitable for people who are happy with their current diet and don’t want to change it. For these people, PN may not offer any benefits over what they’re currently doing.

If you’re looking to make minor adjustments to your diet, you might be better off trying one of the many fad diets that are available.

PN is a new approach and the long-term health benefits haven’t been studied extensively. It’s only available in certain parts of the world and may not be covered by insurance.

If you’re considering PN, you should speak with a doctor before making any changes to your diet.


PN is a personalized approach to nutrition that has received a lot of positive feedback from people who have used it. It can be an effective way to achieve long-term weight loss and better health outcomes. However, this program is not right for everyone.

Those looking for a quick fix might be disappointed by PN, as it requires a significant change in your eating habits and can take several weeks before you notice any results. You should also speak with your doctor before making any changes to your diet to get their professional opinion.
