Is eating behavior manipulated by the gastrointestinal microbiota? Evolutionary pressures and potential mechanisms
Abstract

Microbes in the gastrointestinal tract are under selective pressure to manipulate host eating behavior to increase their fitness, sometimes at the expense of host fitness. Microbes may do this through two potential strategies: (i) generating cravings for foods that they specialize on or foods that suppress their competitors, or (ii) inducing dysphoria until we eat foods that enhance their fitness. We review several potential mechanisms for microbial control over eating behavior including microbial influence on reward and satiety pathways, production of toxins that alter mood, changes to receptors including taste receptors, and hijacking of the vagus nerve, the neural axis between the gut and the brain. We also review the evidence for alternative explanations for cravings and unhealthy eating behavior. Because microbiota are easily manipulatable by prebiotics, probiotics, antibiotics, fecal transplants, and dietary changes, altering our microbiota offers a tractable approach to otherwise intractable problems of obesity and unhealthy eating.

Everything Is Awful and I’m Not Okay: questions to ask before giving up
Are you hydrated?  If not, have a glass of water.

Have you eaten in the past three hours?  If not, get some food — something with protein, not just simple carbs.  Perhaps some nuts or hummus?

Have you showered in the past day?  If not, take a shower right now.

If daytime: are you dressed?  If not, put on clean clothes that aren’t pajamas.  Give yourself permission to wear something special, whether it’s a funny t-shirt or a pretty dress.

If nighttime: are you sleepy and fatigued but resisting going to sleep?  Put on pajamas, make yourself cozy in bed with a teddy bear and the sound of falling rain, and close your eyes for fifteen minutes — no electronic screens allowed.  If you’re still awake after that, you can get up again; no pressure.

Have you stretched your legs in the past day?  If not, do so right now.  If you don’t have the spoons for a run or trip to the gym, just walk around the block, then keep walking as long as you please.  If the weather’s crap, drive to a big box store (e.g. Target) and go on a brisk walk through the aisles you normally skip.

Have you said something nice to someone in the past day?  Do so, whether online or in person.  Make it genuine; wait until you see something really wonderful about someone, and tell them about it.

Have you moved your body to music in the past day?  If not, do so — jog for the length of an EDM song at your favorite BPM, or just dance around the room for the length of an upbeat song.

Have you cuddled a living being in the past two days?  If not, do so.  Don’t be afraid to ask for hugs from friends or friends’ pets.  Most of them will enjoy the cuddles too; you’re not imposing on them.
