are you a SLOW or FAST Oxidizer? interesting facts that can help you lose the weight…

Dr. George Watson, a researcher at UCLA discovered two major metabolic types through odor and blood tests:

Fast & Slow Oxidizers. He found many differences in the two oxidizers including CO2 levels, PH balance and more. Through proper nutrition and supplementation, Dr. Watson was able to improve people’s mental and physical condition.

So how can you tell if you’re a slow or fast oxidizer? What should you eat?

Slow Oxidizer:

  • Metabolism: Slow and experiences low energy levels
  • Bowel movements are slow and infrequent. Constipation.
  • Hair, Skin & Nails: tend to be more dry due to less production of sebaceous and oil glands. Dry skin can make muscle definition look more visible.
  • Blood Circulation: slow flow leading to cold hands and feet.
  • Food cravings: because of low blood sugar, low activity and the inability for the body to properly retain sodium and potassium, the body craves sweets and sometimes salt.
  • Blood pressure: prone to low blood volume and pressure.
  • Sweating: very little or none at all
  • Mood: slow metabolism can cause lethargy, sluggishness, depression and confusion.
  • Protein preference: lean, low fat protein that help normalize metabolic rate
  • Body shape: Pear shape due to sluggish gland and more fat deposits in hips and thighs

SUGGESTED DIET:fusion-chicken-su-1215064-x

    Protein: low fat, high quality lean proteins and legumes preferably with every meal to help stabilize blood sugar. Avoid processed meats like sausage, bacon and pork products.
    Eat your veggies.
    For your oils and fats, try palm-oil, olive-oil, butter, cream, cheese, yogurt, and almond butters. Avoid processed oils/fats like peanut, sunflower, corn or sesame.
    Carbs. Avoid simple sugars and fruit to one a day. Avoid wheat and spelt. Try brown rice, corn and quinoa instead.Drink 8 glasses of water and enjoy your coffee and tea.
    SUGGESTED SUPPLEMENTS: B-complex and vitamins C and E, Zinc, magnesium and calcium

Fast Oxidizer:

  • Metabolism: Fast and experiences high energy levels
  • Bowel movements are more frequent.
  • Hair, Skin & Nails: tend to be more oily due to increased production of sebaceous and oil glands. Dewy skin can make muscle definition look less visible.
  • Blood Circulation: faster better flow leading to warm hands and feet
  • Food cravings: fats, butter, sugar, red meat, and other food that cause slowing of metabolic rate.
  • Blood pressure: prone to higher blood flow and pressure.
  • Sweating: increased activity leads to generating more sweat.
  • Mood: tend to be more anxious, nervous, irritable and jittery
  • Protein preference: high fat protein like red meats.
  • Body Shape: Apple shape. Legs and arms are thin, but due to high levels of cortisol, fat may deposit in the belly area.


    Protein: higher fat cuts of meet are better. Try beef, lamb sardines and eggs. Legumes like black and pinto beans are accepted. Avoid processed meats.
    Eat your veggies.
    For your oils and fats: eat 1 tbsp of high quality fat with every meal. Great examples are flax, hemp and olive oil.
    Carbs. Avoid simple sugars and honey. You may have an apple and berries once a day. Avoid wheat and spelt also. Try brown rice, corn and quinoa, amaranth, and buckwheat instead.
    Drink 8 glasses of water and enjoy your coffee and tea.
    SUGGESTED SUPPLEMENTS: copper, zinc, choline, inositol, calcium and magnesium. They also do well on more of vitamins A and D.
    fullbodyAccording to Dr. Watson’s research, I definitely fall in to the Slow  Oxidizer type.
    I am pear shaped and hold most of my weight in my hips, butt and thighs. I have extremely low blood pressure and tend to get sleepy and lethargic quite often. I also crave salty foods or fruit when I feel my blood sugar dropping. I do find that my body responds better to leaner forms of protein like eggs, turkey and chicken. I have also cut down my fruit intake and noticed a difference in my body.
    Some may fall in between a slow and fast oxidizer, so a diet mixing a little bit of both  is advised. I’m sure your body will tell you how it feels after eating certain foods.
    Even though there are many factors that contribute to weight loss and weight gain, I think Dr. Watson has done a great job in presenting his study and how to tackle the metabolic types. His suggestions of foods and supplements have been found to balance the body to improve a person’s overall physical and mental health.
    I’m a new fan! Go Dr. Watson!

    Interesting, but Dr. Watson was very specific about which vitamins and minerals to use for each oxidizer type, and the nutrients listed above are NOT it! A slow oxidizer will have very adverse reaction to Vitamin E, B12, Calcium and zinc. A fast oxidizer will not do well with magnesium or iron. Watson’s books are out of print, but there are still some available used… Nutrition and Your Mind is really the best, and saved my life years ago. It still applies today.

    Hi Lori,
    Thanks for your great comment. At the end of the day, I believe that every body has its unique formula and we just have to figure it out. I wish it was simple. I totally agree with the correlation between mind and body. Thanks for visiting! Love, Ghada

  3. Jay Bee says:

    I am so confused as to what metabolic type I am. If I am a fast oxidizer or a slow oxidizer. I have belly fat, large hips and thighs. After reading your page it appears that I am both, because I have symptoms of both fast and slow oxidizer. What so you suggest. If you need more info from me, I will be happy to supply you with it. Any help or suggestions you can give me would be greatly appreciated.

    Hi hailey!check your email soon! Let’s talk xoxo

  5. flibs says:


    I’m confused. After I read through and make some reading, I found out I fall under Fast Oxi. But then I have a pear-shaped body. So could you explain more on this. Maybe I face the same problem with Jay Bee. Thanks!

  6. Arissa says:

    I am apparently a fast oxidizer, but I do not have skinny arms or legs. I am relatively fat, but I am confused as to what kind of metabolic type I have. And also, is there an exercise routine that comes with what I should eat?


  7. Trish says:

    You should mention that some people can be “Balanced” or “Mixed” so they would need a combination of both diets. I am a “Balanced Dominant” so I fall in between sympathetic/parasympathetic and slow/fast oxidizer. The online questionnaire is great because they give you color coded charts so you can know which foods to combine together for maximum energy and vitality:

    Thanks for the link Trish!

    Is it possible to lose weight on night shift. I have been going to the gym for two months for an hour 5 to 6 days a week, eating right most of the time, drinking lots of water, and avoiding snacking. I have not lost any weight. Ive done research and it says you must get 7 to 8 hours of sleep but It is impossible for me to do that because I have children I have to take to and from school, I have to cook, and run errands so how am I to go about losing this weight. I havnt found any answers on the web.

  10. Heather says:

    Kat, sleep is very important for REM. That is where you heal your cells. Lack of sleep also keeps insulin and cortisol levels hight which effects normal metabolism and actually increases fat storage. My suggestion would be to focus on making extra time for meditation and exercise to help normalize your insulin levels. That means, finding help and support. Most of us can’t do it alone. Also, look into weight training because that is the best way to burn fat. Stop cardio and focus on that (not sure if that’s what you’re doing). FYI, some people do just fine on 6 hours of sleep. You simply need GOOD sleep.

    I am a balanced oxidizer. I have high blood pressure and type II diabetes. What type of food should I avoid ?

  12. Ericka says:


    I have researched so much about this kind of stuff, and I’m so glad I ended up here so I can tell everyone that reads this that THIS IS SO INCORRECT!! This person has it all flip-flopped. I am a fast oxidizer. I am always pink on my face and my hands are often very cold. I crave cheese and salty foods all the time (I hate acidic foods like pickles and vinegar tho).I store fat mostly on my thighs and butt, as well as lower abdomen (those are my hard-to-target areas as well) but I am completely hour-glass shape. every body is different. KEEP LOOKING GIRLS!! Try Web MD or something else. Don’t believe this.

  13. Ghada says:

    Hi Ericka,

    This post was written in 2009 so if anything seems wrong, then it could be possible. I am not a nutritionist but an average girl with big thighs and hips that’s continuously seeking new studies, diets etc. My mind will continue to be swayed as new studies to come out and now two years later, I agree with you. Everyone is different. If weight loss was that simple, we would all be so fit and slim.

    Thank you for stopping by though and I commend you for pointing it out. Please share any updated link that you might think we would love to read and learn from.

    Please don’t be mad at me lol :) Everything I write was meant to help and share info.

    Love, Ghada

  15. Tim says:

    I have to say I’m skeptical but interested in this.

    While there may be something in this and there may be certain food groups that are better than others for different metabolic types I don’t believe the differences warrant alarm if such a regime is deviated from.

    I myself lost 35 kilos in 7 months through doing nothing more than dropping calories and increasing physical activity. In that time I did experiment a bit with different food types and food timings but found that the rate of weight loss I experienced seemed to be completely unrelated to the types of foods I was eating or when and correlated strongly with the amount of calories in versus calories out.

    Having said this I am interested in this theory and would like to hear more from people that have tried it.

    For interest sakes I come out as a very clear fast oxidizer according to the theory. :)

    Thank you for posting this, it has helped me understand the concept. And for those of you who don’t fit either group, there is a “balanced oxidizer” group with another diet. I don’t know about the doctor’s take on it, but I’m doing the Jillian Michaels weight loss program, and I came out balanced. I have many traits from both sides, but there is a middle ground. On this diet I had to change the percentages of the carbs, fat, and proteins to see results. All I can say is I am happy the scale is finally moving, and even happier that what I had to do to accomplish that was eat MORE fat and calories!!! If this doesn’t work for you, no matter, just keep trying reasonable things until something works for you. I’ve tried weight watchers, south beach, sparkpeople, gluten free, blood type, body type, I was just happy to find something that got me results, I don’t care how anyone feels about it. : ) I feel much better too! I was always tired or wired before, now I feel more balanced physically and mentally than I ever have, and no one was more skeptical than me! Good luck on your journey, wherever it may lead you.

    Metabolic typing is more important than we think and will become more so in the future. Dr. Nicholas Gonzalez uses it successfully with his cancer treatments. Please take time to read “The Metabolic Typing Diet” by Wolcott and Fahey before you make any judgments concerning this important aspect of nutrition. Thanks and good health to all.
