Food Intolerance – Why Your Cross Training Diet is Making You Sick

Many people claim that dairy, gluten, carbs, or even wholefoods are giving them issues. Surprisingly, some of them didn’t have problems with those foods early in life. The question is, could there be a reason for this? Experts in CrossFit training have observed that excessive dieting just like excessive exercise may force the body to adapt to the stress that is constantly being exposed to.

There is no doubt that our bodies are super adaptive machines, but this can work against us depending on the scenario. For instance, an adaptation imposed by diet may favor or work to your disadvantage.

Dietary Distress Cycle

Going on a fad diet or moving back and forth between diets can cause digestive distress and many other negative symptoms. There is a cycle which develops carrying with it the element of food intolerance.

When you are exposed to a new diet, your hormones which include glucagon and insulin change. This, in turn, causes a change in metabolism and negative symptoms which then make you go back to your old diet. The old foods may also react with your body leaving you either helpless or with no option other than getting back into your new diet.

Carbs Not Serving You Well


Most of the people who have problems with carbohydrates never had them before. In fact, they used to load decent amounts of carbohydrates without any signs of negative health effect. However, somewhere in the course of their life, they try out a fad diet from which they start experiencing digestive issues such as acid reflux, bloating, and lethargy.

In some cases, these people have been told that the problems they are experiencing are as a result of adaptation or detox of the new diet. Others believe that the reactions they are experiencing are because of their age and their bodies cannot handle the same foods they did before.

Getting on to the Wrong Diet

When you start seeing problems with your CrossFit diet, it could be that you are on the wrong diet. For instance, ditching animal products can cause a lot of metabolic adaptations. Increasing the number of vegetables and cutting down on meat can push the stomach into an alkaline state which works to reduce stomach acids.

If you avoid fats and all of a sudden you introduce higher amounts of fat in your diet, can make you queasy. When you are on a low-fat diet, your gallbladder adapts. If you re-introduce fats at higher levels, it creates confusion and puts you at a greater risk of gallstones.

The above scenarios are quite common, and chances are high you may have encountered one of them. The bottom line is, if you don’t have a diagnosed medical condition, it is a good idea to revise your CrossFit nutrition and establish a healthy relationship with your diet. Listen to your body and not just the diet app or guru.
