Weight Gain

A common problem observed in Fibromyalgia is weight gain. Many patients complain to me that weight gain became a major problem once Fibromyalgia established itself.

It is not unusual for a person to put on a 25- to 30- pound weight gain in the first year after Fibromyalgia was diagnosed. Various factors are involved in weight gain and include:

1. Decreased Metabolism

Various hormone changes can slow down the metabolism in Fibromyalgia. Studies have shown hormone deficiencies or imbalances (cortisol, thyroid, serotonin, growth hormone) in Fibromyalgia. Insulin and other hormones are probably affected as well.

Dr. Leslie J. Crofford** has described hormonal abnormalities in Fibromyalgia and how they interfere with physiologic communication between the brain and the body. Closely linked with hormones is the autonomic nervous system. The autonomic nerves are the small nerves vital in the coordination of the body’s hormones, and thus they play a role in the regulation and delivery of nutrients to our cells.

The hypoglycemic roller-coaster effect is a good example of the combination of hormonal endocrine imbalances and autonomic nervous system dysfunction leading to hypoglycemic symptoms. Overall, neuroendocrine abnormalities in Fibromyalgia probably interfere with the body’s metabolism (by decreasing it), and part of the treatment involves replacing or supplementing hormones to help improve the body’s metabolism.

A slower body metabolism means fewer calories are burned on a daily basis to “run” the body’s machinery. If fewer calories are burned with no change occurring in calories consumed, weight gain will result over time. Also, women in their late 30s and 40s often develop Fibromyalgia along the same time as early menopause (decreased estrogen). This can further decrease metabolism and increase the potential for weight gain.

2. Hypoglycemia (Abnormally Low Blood Sugar)

As I mentioned earlier, increased sensitivity to insulin will result in too much glucose being removed from the blood stream and pushed into the muscle. All this extra glucose pushed into the muscles has nowhere to go as the muscles have very limited ability to store glucose.

The body is forced to go into a fat-storing mode where it converts this extra glucose into fatty tissue. Contrary to the popular myth that obesity is a result of eating too much fatty foods, obesity is usually the result of eating too many carbohydrates. A carbohydrate rich diet causes weight gain by converting the extra glucose into fat and, if Fibromyalgia causes more insulin activity and sensitivity, then the weight gain can be even greater.

Another myth is that most overweight people overeat. Actually, most overweight people do not overeat. They may have a craving for carbs, and the carbs are easily converted to fat. Fibromalgia facilitates this process. A diet modified in protein and lower in carbs may help.

3. Medicines

Side effects of medicines used to treat Fibromyalgia can cause weight gain by decreasing metabolism, altering hormones, causing fluid retention, and increasing appetite. The most common offending medicines are the antidepressants.

Medicines such as estrogen and prednisone can also contribute to weight gain. If certain medicines are causing weight gain they may need to be stopped or adjusted depending on the individual’s medical needs.

4. Decreased Activity Due to Pain

People with Fibromyalgia hurt more and are not as active because activity increases pain. Thus, it is difficult to increase the energy expenditure or calorie burning related to exercise and activity. Less calories burned can mean weight gain. Any treatment program in Fibromyalgia must include attempts at increasing overall activity level.


We’ve discussed some of the basic problems of Fibromyalgia, the metabolism changes and the dysfunctional carbohydrate responses, especially. The problems contribute considerably to many of our most bothersome symptoms, including aching; fatigue; brain fog; irritability; anxiety; dizziness; carbohydrate craving; irritable bowel syndrome; food intolerance; and food sensitivity.

The American “diet aggravates and perpetuates our Fibromyalgia problems. We may have tolerated the higher carb, low fat diet before we got Fibromyalgia, but since we got Fibromyalgia, this diet no longer works for us and it’s probably making it worse.

• Because of our slow metabolism, it is difficult for us to eat less and notice a difference.

• Because of our pain, it is difficult for us to increase our exercise level to burn off more calories.

• Ideally, we need a diet that improves the efficiency of our calories burned by providing us with the right “quality” of food to enhance our metabolism and calorie-burning abilities.


1. Good proteins.

• Meats, such as lean meats, skinless chicken, turkey and fish. Lean cuts of steaks, sausage, and bacon contain higher amounts of saturated fats so they should be kept to a minimum.

• Eggs. This breakfast staple is a great source of protein; egg whites are healthier.

• Tofu.

• Soy meat substitutes.

• Dairy products. These include cheese, cream, butter, skim milk, cottage cheese and unsweetened yogurt. Try for low fat dairy products.

• Legumes. This class includes beans, peas, peanuts, lentils, and soybeans.

2. Good carbohydrates

• All vegetables. Vegetables are a source of carbs that are highest in fiber and lowest in sugar. Some vegetables such as corn have more carbs than others.

• Fresh fruits. Avocado, raspberries and strawberries have the least carbohydrates of fruits. Avoid dried fruits.

3. Good fats

• Plant oils, especially olive and coconut oil. Other vegetable oils are acceptable including soy, corn, sunflower and peanut.

• Fish oils (rich in Omega-3)

• Almonds

• Avocados

4. Others

• Salad garnishes which include nuts, olives, bacon, grated cheese, mushrooms and other vegetables are allowed.

• Flaxseed oil. A healthy supplement which contains essential fats.

• Artificial sweeteners and sugar-free beverages are allowed in moderation. If you feel you are sensitive to aspartame, avoid products that contain it (NutraSweet) or substitute a different artificial sweetener, such as sucralose (Slenda) or saccharin (Sweet’n Low). Stevia is a sweet supplement alternative to sugar. Xylitol is another one of nature’s sweeteners like Stevia that won’t raise blood sugar levels and can substitute for sugar.

[Note: Dr. Pellegrino’s detailed list of FOODS TO AVOID includes what you don’t see here, such as sweets; breads & pastas, especially white-flour based; rice, especially white; potatoes; partially hydrogenated oils (trans fats); carbonated drinks; alcohol except in moderation. See also his review of the hormonal and nutrient deficiencies commonly found in fibromyalgia patients – “Nutritional Approaches in FM – Deficiencies, Symptoms, and Supplement Strategies”]


1. Think Protein Always

A key with this diet is not to eat any carbohydrate foods by themselves, even if they are considered good carbs. “Orphaned” carbs will increase the risk of hypoglycemia/insulin hypersensitivity in someone with Fibromyalgia, so foods that have some protein in them should be consumed every time we eat. Therefore:

• We shouldn’t eat pancakes and syrup for breakfast because it doesn’t contain any protein. Insulin is controlled by the balance of protein and carbs each time we eat.

• If we want a salad for lunch, we should not just eat plain lettuce and vegetables. We need to have a protein source in our salad as well, such as chicken, tuna, turkey, eggs, cheese and more.

• We should not eat a plain spaghetti supper. We should have spaghetti and meatballs (made with lean ground chuck meat) or lean sausage.

• If we crave a snack, we shouldn’t eat a sugar cookie. A small bag of cashews would be a better protein-laden choice for a snack.

Once you are trained to think about protein every time you put something in your mouth, it becomes easier to stay within the framework of the Fibromyalgia diet.

2. Avoid The Rush

Hypoglycemia is often the result of a sudden surge of glucose in our bloodstream after eating a carbohydrate-rich food. The Glycemic Index of foods is a measure of how fast the carbohydrate triggers the rise in circulating blood sugars. A GI over 70 is high. Examples of food with high GI are: Rice Crispies – GI 80; corn muffin – GI 95; mashed potatoes – GI 88.

To avoid a carbohydrate surge, take a few bites from proteins first whenever you eat. Even if you are eating good carbs, if you take the first few bites from protein, you can minimize the carbohydrate “rush”:

• Eating proteins first activates the protein digesting enzymes and slows the absorption of carbohydrates.

• Plus, proteins require hydrochloric acid for proper digestion, carbohydrates don’t. If we eat carbohydrates first, hydrochloric acid may not be activated and subsequent proteins eaten may not be properly digested.

Foods rich in fiber and fats also slow the absorption of carbohydrates.

3. Eat Until Full

Try to eat at least 3 meals a day and have 1-2 snacks. At meals, eat until you are comfortably full but not stuffed. Some people with Fibromyalgia actually do better by eating 5 to 6 smaller meals a day or by eating 3 smaller meals and 2 larger snacks.

Those who are bothered by irritable bowel syndrome sometimes can do better by eating smaller portions more frequently.

Eat slowly and take your time to chew food well.

4. Weekdays: Behave!

I recommend that the Fibromyalgia diet be followed strictly for 5 days each Monday through Friday, and I allow people to splurge a little on the weekends. That is, the diet is 5 days “on” and 2 days not so “on.” This allows people to follow the basic rules during the week (more proteins, good carbs, good fats) but also allows the anticipation of favorite foods over the weekend….

This Fibromyalgia diet can help decrease sugar cravings, help rebalance your body’s chemistry, especially insulin and blood glucose levels, and can help you shed weight.

  1. LIFESPEAKER says:

    This article really helped! Thank you

    A few years ago I did the first part of the South Beach diet and lost weight. Because of a crazy traveling schedule staying on it hasn’t alway worked but I think I need to try it again.

    1. soffy says:

      I just loved this great article because it gives so much important information that not even doctors knows, everytime I have the chance i come visit the site and i find so much to learn about this chronic illness(fibrom) that i have for almost 7 years now and i can see how much gain i got. keep the good work because i know that like me are other people that needs to learn more about this matter.

    2. soffy says:

      Everything is true I never knew how important was the protein for fibro people until now that i read this article and also your comments. good luck to you. atte. soffy

    3. amieeross says:

      ive been told that ive more than likely to have had fibro for years. ive been getting very tearful lately over my weight and i thought id have a look if it was connected. this article has really helped, i think i can work with this information and help myself alone.

  2. pofolks says:

    Protein first, great tip, haven’t heard that one before. But I didn’t find any real solution to taking off the weight. Does anybody have any ideas that really and I mean REALLY work?

  3. Aberlaine says:

    Since I am always tired, I’m always craving quick energy, like chocolate. I know that’s not good for me but I don’t know where to get quick energy, before I fall on my face.

  4. uxordepp says:

    The more research I am doing, the more I think my FM is a hormonal issue…adrenals, thyroid, insulin…I don’t think a low-fat diet is a good idea at all. Protein? YES. Fat? YES!

    Aside from the nutrients fat contains, it also gives a satiated feeling that skinless chicken just doesn’t do! I avoid transfats and poly unsaturates like the plague, but other than that…Skipping egg yolks? What about the choline? And the flavour?

    Cholesterol is necessary for hormones, too. My HDL is very high. IF FM is hormonal then I want to have the fuel I need to keep things going!

    I am trying to find the balance. I lost 50 pounds over 2 years and suddenly regained 20 of that. I’d had to cut exercise due to weird symptoms, then started to see blood sugar swings. So now I have to find SOME exercise I can do to help both the weight and the sugar swings. Small frequent meals are GOOD!

  5. tplanford says:

    Not a bad article, but we need to get away from the idea that meat & animal products are a good source of protein. I can give you multiple reasons for going vegetarian–including animal welfare–but you should eliminate or restrict meat for your own health as well. The immediate benefit is greater energy–I saw a drastic improvement within only a couple of weeks!

    I’ve been vegetarian (aspiring to vegan) for 5 years now & recommend it to anyone interested in improving their health & decreasing their odds of developing many types of cancer. Do some research & note all the Olympic athletes who embrace this lifestyle.

    1. starstella says:

      While Dr. Pellegrino’s article did not contain any new information, it provided a useful summary of diet details that those persons with FM should be aware. One new suggestion to me was the ingestion of the protein food first when eating a protein/carb meal. Overall, a good summary to have on hand when a Fibromite is feeling in despair over weight gain and their diet, because the review of the basics can help to restore a sense of control over one’s life; being that loss of the sense of control over out bodies is one of the great sources of distress of FM.

    2. casemanagr says:

      What do you recommend for meat replacement for protein on a weight loss regime? I have protein powder to add to smoothies. Right now i am very limited on what i eat as #1 – it must be gluten-free
      #2 I have had all my remaining teeth pulled due to the Celiac disease and Sjogrens Sydrome which just ravished my teeth. I have lost 15lbs from simply not being to eat much besides yogurt, bananas, icream or smoothies. I need some idea or recipes that i can eat and can continue to lose weight as I had gained a total of 100lbs.when this srared. I have about 85lbs to go and i am 56. I want it off by 60 and be vegetarian.

    3. Florist says:

      I am from New England live near Brattleboro Vermont where doctor does Devin Starlyndyl wrote her book, ” The Fibromyalgia Advocate”. Since I’ve had fibromyalgia for 27 years I’ve tried just about everything and on top of having fibro, I I suffered severe trauma at the hands of a patient in 2009. Plan to retire at that time as I ended up with a fractured ankle and tons of soft tissue damage also. I recently decided that I would lose a few pounds so I put myself on a very low carb no meat vegetable diet with almond milk smoothies with fruit and occasional fish. I lost 11 pounds I feel like a new person I have less pain I am NOT taking any pain pills and an occasional Tylenol and I do believe it’s from reducing carbs and having no meat intake. There is protein available from many sources other than meat. The recent documentaries on meat, including beef, pork chicken and turkeys was the impetus I needed to give it up. It’ s a merciless industry. Good luck to all you fibro sufferers.

    I feel like crap if I don’t eat meat. Soy, dairy and legumes mess me up. So meat it is.

  7. lvobrien says:

    As the years progress, I have transitioned away from a vegetarian diet because I find that I am craving animal protein, particularly during certain stages in my menses cycle. Other times I crave veggies high in iron and Fe pills are too hard on my system. When my body can’t tolerate animal protein, I manage well with plant proteins. My indulgence is a particular brand of bbq chips, but I have found that it does tend to make me tired. I had not considered making sure there is some sort of protein, eaten first, at every meal/snack. Other diet changes that have help tremendously is cutting out anything made with white flour (breads, pastas, white rice) and starches like potatoes (being Irish, I LOVE potatoes, but I have switched to yams/sweet potatoes to satisfy those cravings). For losing weight, it continues to be a long long struggle and I’ve plateaued at a weight I’m NOT satisfied with, but my body seems fine with. Following various food management programs have never worked so I started treating it like an input/output scenario. If the amount I eat (in calories) exceeds my exercise, weight stays. If my output exceeds my input, weight peels off, very very slowly. I’m not starving myself and I eat pretty much what I want, when I want, but I do exercise as much as I can tolerate and whatever I can tolerate.

    A few years ago I changed my diet. I have never been a meat eater. But my new husband loves meat. So I started eating more of what he liked and less pasta, potatoes etc. I have lost about 40the lbs with no exercise. I eat junk foods once or twice a week in small quantities. I had pteviously tried to lose weight and was unsuccessful. There is alot to be said for proteun diets. 🙂
