Recently scientists revealed how fast eaters were at increased risk for being overweight and having metabolic syndrome and multiple cardiovascular-disease risk factors.Rapid eaters don’t fully chew their food and may not activate the neurological pathways needed to light the digestive fire. Two studies have found that chewing forty times before swallowing led to decreased levels of the hunger hormone ghrelin and increased levels of two critically important gut peptides, cholecystokinin (CCK) and glucagon-like peptide-1 (GLP-1).
Overall, mindful eating and chewing at least forty times per swallow is linked to reduced food intake. Thorough chewing may activate the vagus nerve that communicates with the digestive tract, optimizing digestion and the release of gut hormones, which help us to balance blood sugar and burn more fat.
Tools to Increase Mindful Eating
One of my most effective tips for weight loss is helping clients to practice meditative breathing prior to a meal. Eating in a rushed, stressed physiological state leads to poor chewing, improper digestion, and imbalanced gut microflora. In contrast, mindful strategies such as deep breathing will increase the “rest and digest” or parasympathetic nervous system including the vagus nerve, which activates digestive juices and gut hormones such as CCK and GLP-1. Vagus nerve activation is key to optimal digestive health.
is a great way to boost your gut-brain communication axis, and keep inflammation away. Since starting HeartMath in 2011 I’ve noted great improvements in my own body composition, digestion and even public speaking. My clients report similar feedback.
This inexpensive device can be used anywhere; just 5 to 10 minutes per-day can have profound effects.
This headband is pretty amazing. I’ve only logged 10 hours of so since purchasing it, but using the headband before breakfast, dinner and bed has been a major help in my digestion and cravings. It’s slightly more complicated to use than HeartMath, but is a nice feedback device that may resonate with you in a different way.

Learn More About Digestion and the Vagus Nerve
There are two divisions of your nervous system running on autopilot in the background: the parasympathetic nervous system, or the rest and digest system, and the sympathetic nervous system, the “fight or flight” response. We are hardwired to survive as if we lived in prehistoric times when life expectancy was contingent upon surviving predators, starvation, and infection. When prehistoric man was fighting or fleeing from a life-threatening altercation, our nervous system pivoted out of rest and digest status (parasympathetic dominance) into fight or flight mode (sympathetic dominance).
Such a shift in nervous system signaling drives the adrenals to release more stress hormones, which increases blood sugar, constricts blood vessels, raises blood pressure, and speeds heart rate. The shift also reallocates nutrients and blood to the lungs, heart, muscle tissue, and brain. Digestion, muscle building, production of growth and sex hormones—all of which are activated by the vagus nerve of the parasympathetic nervous system—come to a screeching halt, since these activities aren’t critical to survival during life-or-death situations. However, that’s not true in the long term.
