(the art of eating according to your genes)

Nutri- (i.e., Nutrition)-genomics (i.e, genetics) is the sciences that uses DNA components to inform us on the relationship between our genetics, diet, and risk of diseases. It also, encompasses the effect of diet on genetic changes. 


It's been known for decades that “one size doesn’t fit all”, but were still missing many pieces of the puzzle when it comes to nutrition. Thanks to omics technology nowadays we are able to answer we people respond to diet and exercise differently, and nutrigenomics was one of the reason. Providing nutrition recommendation tailored to individual's genetic-make is one of the main approaches to providing a “Personalized Nutrition” plans. Recent nutrigenomics studies have shown that genetics influence the rate of weight loss, fat, protein and carbohydrate metabolism, as well as eating habits and body response to different type of exercises. 


Nutrigenomics test allows you to examine your body response to:


1-   Macro nutrients (fat, carbohydrate, etc)

2-   Metabolism and weight loss 

3-   Eating habits

4-   Micronutrients metabolism and risk of diseases (vitamin B complex, omega 3,       vitamin D, and calcium)

5-   Body response to sport and exercises

6-   Bone & joint health, risk of injury 

Your genes load the gun, 
your choices pull the trigger

Healthy aging starts from the moment you are born. Similarly, environmental factors, such as diet, start to influence your genetics at the first stage in life.


Diet can modify your genetic effect and thus enhances or decreases risk of disease based on what you choose to eat.

Tiered of following many different diet, do you find yourself reaching a plateau and don't know what to do?

Are you an athlete who is competing or playing in a team. 


The gene diet is planned based on your body unique genes, and it identify your strength and weaknesses when it comes to body response to different type of diets and exercises.   

Some nutrients deficiencies are more prevalent in certain cultures compared to others. Simply due to the effect of genetics on nutrients absorption and metabolism. 


Vitamins and Minerals are essential in many steps in cell cycling, DNA methylation, oxygen transportation, cell death and repair! Thus, are crucial to be suffeciennt during fertilization, pregnancy, and early stages of life. 


Meet Our Diet


Ohood Alharbi MScFN, PhD is the founder of Personalize My Diet, an online nutrition clinic specialized in nutrigenomics and  personalized diet. Dr. Ohood completed her undergraduate degree in Medical Laboratories specializing in microbiology and genetics. She was awarded her Masters degree in Food and Nutritional Sciences in 2012 and her PhD in nutrigenomics (aka how to eat according to your genes) in 2018. During her PhD, she also completed Independent-Dietetic Practicum in different settings including Nurse Practitioner community clinic, Retirement community and long term care as well as home care. Dr. Ohood, however, is not practicing as a dietitian.

Dr. Ohood completed her PhD studying the association between dairy products and risk of cardiometabolic diseases using the genetics of lactose intolerance as an indicator of dairy consumption. This method is very well known and recognized as "Mendelian Randomization studies". Surprisingly, around the same period Dr.Ohood started her PhD she also got affected by secondary lactose intolerance. Dr. Ohood is a fitness enthusiast and thus she drinks at least 2-3 cups of milk per day between protein shakes, coffee, and cereal. Individuals with lactose intolerance lack the enzyme lactose that digest lactose the main sugar in milk. Therefore, Dr. Ohood dedicated her time to understand the interaction between genetics, dairy, and the gut microbiome. During the period she was eating according to her gene while promoting a healthy gut microbiome, that can help her in digesting milk with no symptoms, Dr. Ohood noticed a difference in her body composition, over all health, and strength. 

Dr. Ohood is an IBS (Irritable Bowel Syndrome) survivor, who truly believes that diet should be individualized to each person age, gender, goals, needs, emotions, genetics and microbiome.  

 Dr. Ohood is also a public speaker, she presented in different organization to educate and spread awareness about the interaction between diet, genetics, and health. She has been a reviewer in multiple scientific journal including PEN: a Practice-based Evidence in Nutrition, a powerful database delivering evidence-based answers to health professionals.
