Food Sensitivities and Weight Gain - Understanding the Connection (2024)

The connection between food sensitivities and weight gain lies in understanding how food sensitivities cause inflammation and the overproduction of cortisol. Chronic overproduction of cortisol leads to insulin resistance and an inability to lose weight.

If your struggling to lose weight and have inflammation, you will want to avoid these seven common food sensitivities that cause weight gain and inflammation.

The most common food sensitivities to inflammatory foods such as gluten, dairy, and soy may be the reason why you can’t lose weight even when it may seem as though you are doing everything right such as exercising and not overeating.

Gluten, dairy, eggs, peanuts, sugar, corn, and soy are the most common food intolerances that cause weight gain.

By simply removing these food intolerances that cause weight gain, inflammation is lowered, making it much easier to lose weight.

Can food allergies cause weight gain?

Food allergies can cause weight gain as a result of immune system activation. The immune system creates inflammation, which in turn leads to chronic cortisol production and insulin resistance. When insulin levels are consistently raised it becomes difficult to lost weight.

Food sensitivities can develop as a result of a leaky gut that lets undigested food through the intestinal lining. The body does not recognize the undigested food as a nutrient. Instead, the body thinks the undigested food is a foreign invader and mounts an immune response to that particular food.

Food allergies can develop when the body’s immune system creates antibodies to a protein component found in common allergenic foods such as the protein gluten in wheat or the protein casein found in dairy.

​When the immune system is activated, it creates antibodies such as an IgG antibody against a particular food. Whenever a food that has antibodies created against it is eaten, the immune system is activated. When the immune system is activated, it creates inflammation as it attacks the offending food.

Food sensitivities and weight gain – Understanding how inflammation causes weight gain

When the body is chronically inflamed from eating these common foods sensitivities daily, this puts stress on the adrenals. The adrenals are responsible for the production of cortisol, which is an anti-inflammatory that your body uses to counter the effects of an overreactive immune system that is challenged by common food sensitivities such as gluten, dairy, soy, and sugar.

Cortisol is known as the stress hormone, but cortisol is not all bad. Cortisol is a natural anti-inflammatory produced by the body to combat inflammation. The more important question to ask is what is causing excess cortisol production? Which, by the way, can lead to adrenal burnout andhormonal imbalances.

A contributing factor to chronic cortisol production is food sensitivities! The body produces cortisol to combat the inflammation created by the immune system. The immune system creates inflammation in response to fighting food sensitivities or allergies.

Foods allergies and sensitivities that are stimulating the immune system, must be removed from the diet to allow the immune system to cool off and stop creating inflammation.

The connection between cortisol, inflammation, and weight gain

Another role of cortisol is to breakdown muscle and fat tissue to raise blood glucose in an emergency when blood glucose drops too low.

But when cortisol levels are elevated to offset the inflammation created by the immune system and offending food sensitivities, blood glucose levels are also raised. When blood sugar levels are constantly raised this can lead to insulin resistance due to excess glucose always being in the bloodstream.

Cortisol causes insulin resistance and contributes to weight gain by consistently raising blood glucose levels in the bloodstream, which then leads to consistently elevated levels of insulin. High levels of insulin keep the body in fat storage mode.

Insulinis the primary hormone responsible for weight gain. The higher the insulin levels, the harder it is to lose weight as insulin tells your body to store fat.

Cortisol is the stress hormone responsible for belly fat, but it is the food that stimulates chronic cortisol production.

Food allergies cause weight gain by stimulating the immune system, which creates inflammation. Cortisol is produced to combat inflammation, but cortisol also raises blood sugar, which leads to insulin resistance and the body in fat storage mode.

The cause of the inflammation needs to be removed to stop this vicious cycle. In this case, the cause of inflammation is a food allergy or food sensitivity.

Foods that can also cause weight gain include sugar and highly processed refined carbohydrates such as white bread, as those foods spike insulin and tell your body to store fat.

The best way to reduce cortisol levels through diet is by removing inflammatory foods, which can lead to insulin resistance. Remove refined carbohydrates and sugar, which disrupts blood sugar balance to prevent the overproduction of cortisol.

Why is it that some people lose weight when initially stressed and others gain weight when chronically stressed?

Initially, cortisol can cause weight loss as it signals for the breakdown of muscle and fat tissue to raise blood glucose. BUT when cortisol levels remain high, it causes insulin to be elevated above normal.

When insulin levels are too high, it is difficult to lose weight due toinsulinalways being present and telling the body to store fat instead of burning fat. This can leave a person feeling fatigued and struggling to lose weight.

As you can see, everything is connected in the body. These common food sensitivities cause inflammation and weight gain as a result of cortisol consistently stimulating elevated insulin levels that keep the body in fat storage mode.

This is how food intolerance and weight gain are connected, but by removing the food sensitivities that are causing inflammation, weight loss becomes easy.

To find out if food sensitivities are causing weight gain and are problematic for you, I recommend avoiding gluten, dairy, sugar, and soy 100% for three weeks. After three weeks, challenge each food separately three days apart while tracking and taking note of any abnormal symptoms.

Common food sensitivity symptoms include headaches, bloating, skin rashes, runny nose, cough, stomach ache, irritable bowel, puffiness, and an inability to lose weight.

By avoiding these most common food sensitivities, you may lose weight if inflammation caused by food sensitivities is the cause of your weight gain.

For more information on how these common food sensitivities cause weight gain, I recommend readingThe Virgin Dietby JJ Virgin.

Losing weight is not as simple as counting calories. Ditching common food sensitivities, including dairy, soy, and gluten is a must for anyone wanting to lose weight without counting calories. If you want to find out your food sensitivities I recommend bioresonance food intolerance testing to get started.

Just because you have to remove diary and sugar doesn’t mean you can’t enjoy healthy treats such as this dairy free and sugar free ice cream!

How does inflammation cause weight gain? ›

Meanwhile, the resulting inflammation impairs the body's ability to process insulin, which leads to higher glucose levels and liver fat accumulation, which further impairs insulin processing. This, of course, can lead to more weight gain, which in turn leads to further insulin resistance, and on and on it goes.

What autoimmune disease causes food sensitivities? ›

Such is the case in celiac disease, where ingestion of gluten causes some of the body's immune cells, called T-cells, to mount an immune response against it as if it were a foreign invader. The immune system initiates an inflammatory response that damages the small intestine's villi, leading to malabsorption.

What are 3 common food sensitivity symptoms? ›
