What do Michael Phelps, Serena Williams, and Usain Bolt have in common? 

They are all considered to be some of the greatest athletes in the world. But becoming one of the greats isn’t just due to excellent physical ability and determination. Other factors, such as nutrition and diet, also plays a part. Therefore, these pro-athletes need the best sports nutritionists in the game.

For those reaching peak physical performance, a solid training routine alone will not be enough. It should be paired with dietetic advice from an accredited sports nutritionist.

An athlete's body goes through strenuous physical activity during training sessions. This constant use of the body’s muscles causes energy to be used up a lot faster. For an athlete, their bodies become their tools and it is important to maintain that tool at its peak ability.

A qualified sports nutritionist will be able to take into account age, gender, level of fitness, and even your genetic background to breakdown your metabolism and allow you to unlock your full potential.

Nonetheless, even if you aren’t training for the Olympics but simply the next local half marathon, you might also benefit from dietetic advise from a registered sports nutritionist.

What is a Sports Nutritionist?

First and foremost, a sports nutritionist advises athletes on nutritional regimes that will allow for peak performance. They must understand the unique science of how nutrients and organic substances are used in the body while under constant stress.

A dietitian or nutritionist specialized in sports medicine works on creating a balanced diet for their client. They may also work closely with the coaches, exercise physiologist, and team managers.

Nutrition is of vital importance when it comes to athletes in strength sports and endurance sports, such as track and swimming.

A sports nutritionist is usually found working for colleges and athletic teams on a professional or Olympic level. There are also plenty of sports nutritionists that work at private centers or even at your gym. Like regular dieticians, sports nutritionists should be properly accredited through a state’s registration program in addition to having specialized in sports nutrition.

Sports Nutritionists in LA

In a city where there are so many ways to keep active, there are those Angelinos that have taken this activity to the next level. If you are a player on the LA Lakers or a swimmer on the USC Swim Team, there is a chance that you already have access to some of the best sport nutritionists in the state. But if you aren’t, it doesn't mean that you can’t also have access to the knowledge of nutrition from someone specializing in sports nutrition.

There are plenty of sports nutritionists in LA that aren’t occupied with a professional sports team and can be of service to you.


As a former Team Nutritionist for the LA Clippers of the NBA for over 7 years, Meg Mangano has an impressive knowledge on all things nutrition relating to pro athletes. In addition to working for The Clippers, she also served as a dietician for national soccer teams around the world and teams within each of the major sports. She understands that every athlete has different needs that make up their individual nutritional blueprint, which she then uses to fuse together a dynamic diet plan.

She has worked with professional athletes as well as regular gym goers that are looking for more effective ways of looking into their daily nutrition.

Meg uses a combination of individual nutrition counseling, supplements, functional nutrition, and her sports background to create a custom program and individual meal plan to help athletes reach their optimal performance level.

Nutritional Advice in Houston

In Houston, you’ll find multiple clinics and private practices that focus on diet consultations and are accredited by the American Dietetic Association. A couple of these centers also specialize in providing services for serious athletes.

It is important to note that sports nutritionists might have the same accreditations but they differ from one another in the amount of experience and practice they have had in their respected field.

When looking into a sports nutritionist, it is important to highlight that you are looking for someone that will be able to understand the effects that constant exercise has on your body and that it changes the way your body uses up the nutrients.

  • Resting Metabolic Rate (RMR) Measurement: Measuring your resting metabolic rate tells you the number of calories your body burns when at rest. Additional calories are added to the RMR to determine total calories needed per day.
  • Body Composition Analysis: Body composition analysis uses hydrostatic weighing to measure the amount of fat versus lean tissue as a percentage of an athlete's total weight. Body mass and body composition in athletes vary by sport and position and can be improved through nutrition and exercise.
