There are more organisms living in your gut than there are cells in your body. Many of these organisms are good guys that synthesize vitamins and fatty acids, neutralize toxins, and make hormones. Others aren’t. As they ferment the food you eat, they release toxins that can slow metabolism and make you feel fatigued.
Taking antibiotics, eating meat laced with antibiotics, eating too little fiber, or consuming too much sugar can throw off the delicate balance of bacteria and other organisms in your gastrointestinal tract. When antibiotics reduce levels of healthy bacteria or when sugar overfeeds yeast and unhealthy bacteria, levels of healthy bacteria drop and yeast and harmful bacteria proliferate. Yeast secretes toxins that weaken the immune system and cause the following symptoms: gas, diarrhea/ constipation, bloating, gastric reflux, post-nasal drip, brain fog, fatigue, increased appetite, headaches, rashes, and food allergies.
Despite popular belief, yeast overgrowth isn’t something that only affects women. Plenty of men have it, too. We recently treated an executive who had been diagnosed with sleep apnea and was using a breathing machine to keep his windpipe open at night. It turned out that a yeast overgrowth in his GI tract was causing an excessive amount of post-nasal drip. Within 4 days of starting our diet, the man was no longer using his breathing machine, and his wife no longer complained of him snoring.
