1. Eat a high-fiber diet with good carbs. Because Firmicutes are needed to absorb fats,higher fat diets cause you to have more of them, leading to weight gain.
2. Avoid sugars and processed carbs. Firmicutes are so well-suited to grow on sugars that they're known to grow rampantly in factories that process sugar-cane into table sugar.
3. Raise your intake of beans since they are among the very best foods to raise your Bacteroidetes. What if you cannot digest beans? Along with being a nuisance, that symptom can be a strong sign you have too few Bacteroidetes. Rather than avoid them completely, studies have shown that if you add beans into your diet slowly, and stick with them, the symptoms will go away. To train your bacteria to digest beans well, I encourage you to add just 1 tablespoon of pinto beans daily to the evening meal for two weeks. After two weeks, most people are able to digest more typical amounts.
4. Sleep and eat on regular schedules. Cutting-edge data have shown that our intestinal bacteria have a rhythm that changes throughout the day just like our sleep-wake cycle. Shift work, jet lag and erratic meal times can hurt our good bacteria just like antibiotics can.
