In a recent study, scientists made the connection between specific strains in the gut bacteria of rats, and their mood and behavior.[ref url=”https://www.nature.com/articles/s41380-019-0380-x”]
Rats were split into two groups — one group got to chill in a relaxed environment, and the others were grouped with aggressive rats to rile them up. Within the high conflict group, rats were categorized as resilient or vulnerable, depending on how quickly they backed down to the aggressive rats. After a few days of frequent conflicts, researchers analyzed the gut bacteria profile of fecal samples of both groups.
Researchers found that vulnerable rats had more Actinobacterium, Bacillus, and Clostridium strains and less Bacteroidetes than the rats who experienced zero conflict. The microbiome of resilient rats, who displayed confidence in the face of adversity, more closely resembled that of relaxed rats.
The research team took it a step further and tested whether or not transplanting the bacteria of high-conflict rats into relaxed rats changed their behavior. They found that relaxed rats who received transplants from vulnerable rats started to show behavioral signs of depression.

Gut bacteria, mood, and behavior in humans

Although this was a rat study, it gives a larger picture of how gut bacteria influence your mood and behavior. It’s not the first study of its kind — the body of knowledge around the gut-brain connection is expanding every day. You can read about how your gut bacteria control your mind here, and here’s an article about the connection between gut bacteria, stress, and mood.
One of the best things you can do for your physical and mental health is to fix leaky gut, a condition where certain overgrowths lead to weak spots in intestinal walls, and to encourage a diversified gut microbiome. Here’s how to get started.
Ketones, or ketone bodies, are chemicals that your liver makes when glucose (sugar) and glycogen (your body’s back-up carbohydrate stores) aren’t available for energy. You can read
Once you cut carbs or you’re over the
When your body gets the signal that you’re low on carbs and it’s time to break down fat for energy, acetoacetate is the first type of ketone body your body releases. When you first start, you have more acetoacetate than the other types of ketones, and as you continue, your beta-hydroxybutyrate levels climb until you’re producing all three in steady, sustainable proportions.[ref url=”https://www.ncbi.nlm.nih.gov/pubmed/16848698″]
Beta-hydroxybutyrate (BHB) is the good stuff. It packs the highest energy potential of the three ketone types, and your body really starts pumping out BHB during an extended fast or after the first few weeks on a ketogenic diet.[ref url=”https://www.ncbi.nlm.nih.gov/pubmed/16848698″]
Acetone is what you get when BHB or AcAc break down, and it’s the same acetone that goes into nail polish remover. Your body will use it for energy, but only if there’s an immediate energy need. It breaks down quickly and your body kicks it out fast. Acetone is the reason some people notice “keto breath,” a metallic taste that some people experience during the first couple of weeks on a ketogenic diet. That’s a sign that your body is releasing ketones, and you eliminate it through sweat, urine, and by exhaling.
Ketones from a bottle or capsule are known as exogenous ketones — ketones from an outside source.
Ketone salts are ketone bodies, bound to a mineral: calcium, sodium, or magnesium.
There’s an easier way. You can raise your ketones, crush cravings, and shoot your energy through the roof with a hack that doesn’t involve taking shots that taste like disinfectant. Quite the opposite — you’ll look forward to your ketone hit every morning.
Technically, exogenous ketones can pump ketones into your bloodstream while you’re in the glycolytic (sugar-burning) state. But, is that a good idea?
The transition to the fat-burning state is different for everyone. Things like your gender, age, your starting weight, your insulin sensitivity, and your body composition together determine how you react to carbohydrate restriction.
