Do Food Allergies Prevent Weight Loss?

Do Food Allergies Prevent Weight Loss?

Posted on 06. Sep, 2010 by in Uncategorized

I’ve written about food allergies and sensitivities before in my blog. In fact, I even wrote about my elimination diet experience in this article, “What I’m Going to Do in the Next 30 Days.” Since my first round of elimination diet in 2009, I have since learned a lot more about food sensitivities and have been really fascinated as to how they occur and what we can do to avoid them. Ultimately, I was interested in finding out which types of foods causes digestion problems, health problems, and the inability to lose weight.


I got even more curious after a client of mine, Mary (not her real name), who was diagnosed with Celiac disease had trouble losing weight even after reporting to be eating fairly healthy, low calorie meals and working out with me twice a week for almost 8 weeks. I was baffled. After some research, I found a few facts about Celiac Disease from Here they are:

Celiac Disease (CD) is a lifelong inherited autoimmune condition affecting children and adults. When people with CD eat foods that contain gluten, it creates an immune-mediated toxic reaction that causes damage to the small intestine and does not allow food to be properly absorbed. Even small amounts (1/8 of a teaspoon) of gluten in foods can affect those with CD and cause health problems. Damage can occur to the small bowel even when there are no symptoms present.

Gluten is the common name for the proteins in specific grains that are harmful to persons with celiac disease. These proteins are found in ALL forms of wheat (including durum, semolina, spelt, kamut, einkorn and faro) and related grains rye, barley and triticale and MUST be eliminated.

Here is a list of foods (other than Gluten) which may cause food allergies:

  • Soy and Soy Products
  • Peanuts
  • Wheat/Gluten and gluten containing products
  • Dairy
  • Eggs
  • Alcohol
  • Coffee
  • Ingredients in most processed foods like preservatives

So, to help Mary out, I had her write a full week’s worth of meals so I can review them for her and eliminate the usual “suspects” that cause food allergies or food that may contain gluten. I did this because when people say they are eating healthy, it really is relative when it comes to food allergies. For instance, I might think that whole wheat bread is healthy but if I’m sensitive to gluten then, I would still get sick.

In Mary’s case, I found that she had been drinking her protein drink each morning which is made out of soy ingredients. Soy is one of the usual suspects when it comes to food allergies and sensitivities. I had her stop drinking it and she came in one day with a 1 lb weight loss. That is just from taking out the soy “drink” but we still have lots of work to do. After looking into her food diary in more detail, I found that she is still eating regular bread which has gluten, dairy products, ranch dressing, ice cream, crackers, and all sorts of cheeses. While I’m not implying that she may be allergic to dairy, it could be one of the causes of her food allergies. We will never know until she fully takes them out of her diet. Even after her medical tests have shown she’s not allergic to gluten, having celiac disease means she can not tolerate this protein which means that tests can only tell us so much. The real experiment happens in the real world when you stop eating allergy causing foods and start feeling better.

In my case, my little experiments told me that I’m sensitive to dairy and peanuts for sure. I now have switched my Whey protein to a Vegan protein powder that I truly love. I used to think that I’m sensitive to wheat/gluten because I used to eat my breads with peanut butter. Now I know for sure that it was the peanuts that was making me sick and bloated. Whether I’m sensitive to wheat or not still remains to be seen but to err on the side of caution, I let myself have gluten free days.

While I was researching my content for this article, I came across a blog by Alison St. Sure who was also diagnosed with Celiac disease. At her Sure Foods Living Blog, she wrote an article about, “Why are food allergies on the rise?”. If you want to see the answer to this question, you should head over to her blog and find out. I totally agree with her reasons #3 and #4.

What Do Food Allergies Have to Do with Weight Loss?

When we are allergic to certain things, our bodies treat them as toxins which in turn prevents our digestive system from working to its full potential. We end up storing toxins in our fat cells to keep them away from our vital organs which results to water retention. In addition, our ability to absorb nutrients from the foods we eat is impaired which may cause problems in other systems in our body. But, be aware that even if you are eating non-allergenic foods and/or gluten free foods, you may still not lose weight if you’re eating more calories that you are supposed to eat.

Regarding the above video, I agree with her when she defines the word “diet” as a way of eating and not a specific weight loss program that you do for a short period of time. However, I disagree when she says that eating gluten free is simply a fad. It may be a fad for some celebrities but for real people who experience discomfort and disease, it will be a way of life.

For people who have been diagnosed with Celiac Disease, here is a great book from The View Cohost, Elisabeth Hasselbeck which you can buy from => The G Free Diet. You can also check out her web site at

The Benefits from Eating Allergen-free Foods

Personally, I have experienced many unexpected benefits from eating allergen-free foods. I say unexpected because I originally was just experimenting with taking these foods out of my diet and seeing if I will lose weight. To my surprise, I also experienced increased sex drive (too personal I know but it’s a very important breakthrough for me), less hunger, no more cravings, deeper and more relaxing sleep, less bloating and water retention, fitting into clothes better, a few pounds of weight lost, better smelling breath even with dry mouth, a real feeling of wellness, etc. I can go on and on about all the benefits I have experienced and this is also why I am writing about this topic. I want to share my experience with you hoping you will try it and experience the benefits yourself.

    Great article. I did not know that by taking out Allergen-free Foods. Very helpful.

    If anyone is interested in losing weight go to my page at for a great special.

  • Excellent topic! Reading your article has let me think about giving more tolerance and understanding of people's issues with weight.
    If someone had a problem with losing weight I would just think arrogantly ” Idiot just eat less,exercise more” but now I'll definitely go easier now as there might be more complex issues involved then just eating the right amount of food.

  • Raymond, you're definitely right on the mark. Some people really do have a

    problem losing weight. Sometimes its due to food intolerances while other

    times they may have a thyroid condition. Most of the time though, a lot of

    people can benefit just by eating less unless they have other things going

    on in their body.

    Thanks for stopping by!


  • Wow! What a great article. I never realized that there were so many different food allergies. I never really thought that I had any, although I now wonder how my body is affected by different types of foods. I have started eating more of a paleo diet this year, although not exclusively, and I am able to drop weight easier because of it. I am a big fan of intermittent fasting and that combined with a paleo diet has worked incredible for losing fat.


  • Thanks, Kelly. I should've have mentioned in the article that eating a Paleo

    style diet does get rid of a lot of allergy causing foods in our diet. When

    we eat Paleo style, we take out a lot of processing and foods like corn and

    peanuts that have permeated a lot of packaged foods as ingredients or

    additives. Thanks for your input!


  • Anna,

    you might be onto something here. At the very least, ew should try to at least restrict (so treat them like an addition/dessert) those foods and not completely base our eating on them.


  • I like your attitude, only a few people can do that or will take time to conduct studies on his eating habits. It only shows that you are too determined to change your lifestyle for a healthy life ahead. Probably this post would be very helpful to those who are suffering from CD.

  • I think that anyone can benefit from cutting out gluten from their diet and losing weight as a result.

    As for eggs, it's such a nutritious food. I've found that people that have egg allergy can often eat it raw and still benefit from this great food. If you're going to eat it raw, make sure you get organic free range eggs.

  • I'm not sure about eating raw eggs if you're allergic to it. I don't have any experience in that so I can't comment.

    Thanks Anna, that was an interesting read. I know there is a strong correlation between stress, lack of sleep and weight gain. Many people attribute it to cortisol. It does make sense that allergies would also impact your fat loss, because allergies are another stressor on the body.

  • That’s a great way of putting it, Wayne. Our bodies recognize allergens as “threats” so it definitely is a stressor. Thanks for stopping by!
