When it comes to weight loss, it’s important to trust your gut.By that, we mean eating when you feel hungry and stopping when you feel full—a mindful approach to eating that doesn’t include restricting foods (think: the keto diet) or the times you eat during the day (think: intermittent fasting). And we also now know that it’s crucial to trust—and support—your gut bacteria. The good bugs in our gut have a direct impact on our ability to lose weight, according to a 2021 study published in the American Society for Microbiology (ASM)’s journalmSystems.“Your gut microbiome can help or cause resistance to weight loss and this opens up the possibility to try to alter the gut microbiome to impact weight loss,” lead study author Christian Diener, Ph.D., a research scientist at the Institute for Systems Biology in Seattle, Washington,tells theASM.To determine this, the scientists analyzed a selection of people enrolled in a diet or exercise intervention program that included dietitian- and nurse-lead behavioral coaching. During the six- to 12-month program, 48 participants lost more than 1% of their body weight per month, and 57 individuals maintained the same body mass index (BMI) and weight.Body mass index(BMI) is a measure that’s often used in healthcare to determine a person’s body weight category such as overweight or obese, and therefore, chronic disease risk. However, it has limitations and does not account for individual factors that influence one’s health status, such as body composition, ethnicity, race, sex and age. This is why it shouldn’t be used as a comprehensive measure of someone’s health andcan be a source of body size stigma and bias.Using metagenomics (aka analyzing stool and blood samples) and controlling for age, sex and starting BMI, the researchers compared the following factors for the weight loss and steady weight groups:Blood metabolitesBlood proteinsClinical labsDietary questionnairesGut bacteriaA few common factors were found among those in the group that lost weight, including genes that help beneficial bacteria grow at a more rapid rate, multiply more frequently, replicate and assemble cell walls.“Before this study, we knew the composition of bacteria in the gut was different in obese people than in people who were non-obese, but now we have seen that there are a different set of genes that are encoded in the bacteria in our gut that also responds to weight loss interventions,” adds Dr. Diener. “The gut microbiome is a major player in modulating whether a weight loss intervention will have success or not. The factors that dictate obesity versus non-obesity are not the same factors that dictate whether you will lose weight on a lifestyle intervention.“How a Healthy Gut May Be the Key for Reducing Stress and AnxietyGetty Images / ondacaracola photography / Hiroshi Watanabe4 Ways to Build Better Gut BacteriaWhether you have these gut-healthy genes or not, you can drastically adjust (and improve) the health and strength of your gut bacteria.Eat More ProbioticsProbiotics likeLactobacillusandBifidobacteriumfound in yogurt, kefir, tempeh and more are the “good bugs” that populate your gut.7 Must-Eat Fermented Foods for a Healthy GutThen Keep ‘Em Strong with PrebioticsJust like any other living thing, this bacteria needs food to survive and thrive.

High-protein foods contain carnitine, but red meat has the highest levels. Opt forfatty fish, chicken, turkey or plant-based proteins instead on most occasions, and if you do eat red meat, aim to do so in moderation.Limit Low-Nutrient, Highly Processed FoodsIt’s hard to study “processed foods” as a whole because each food has different ingredients—but the biggest issue with processed foods is that they lack several nutrients, including fiber that feeds gut bacteria, and may be filled with added sugars, salt, artificial sweeteners and/or additives and preservatives. Your microbiome thrives on a diversity of dietary fibers and polyphenols from a variety of colorful fruits, vegetables, whole grains and other fresh and lightly processed plant foods. That’s not to say that you have to avoid all processed foods—there areplenty of healthy optionsthat make eating healthy easier (think: canned tomatoes, whole-wheat bread and pasta, and even things like frozen veggie burgers).

4 Ways to Build Better Gut Bacteria
Whether you have these gut-healthy genes or not, you can drastically adjust (and improve) the health and strength of your gut bacteria.
Eat More Probiotics
Probiotics likeLactobacillusandBifidobacteriumfound in yogurt, kefir, tempeh and more are the “good bugs” that populate your gut.

Then Keep ‘Em Strong with Prebiotics
Just like any other living thing, this bacteria needs food to survive and thrive. Prebiotics are the fibers that do just that—act as fuel to feed the probiotics in your gut. Add apricots, artichokes, almonds, pistachios and legumes, pluspolyphenol-rich foodslike blueberries, strawberries and apples for a good dose of prebiotics.

High-protein foods contain carnitine, but red meat has the highest levels. Opt forfatty fish, chicken, turkey or plant-based proteins instead on most occasions, and if you do eat red meat, aim to do so in moderation.
Limit Low-Nutrient, Highly Processed Foods
It’s hard to study “processed foods” as a whole because each food has different ingredients—but the biggest issue with processed foods is that they lack several nutrients, including fiber that feeds gut bacteria, and may be filled with added sugars, salt, artificial sweeteners and/or additives and preservatives. Your microbiome thrives on a diversity of dietary fibers and polyphenols from a variety of colorful fruits, vegetables, whole grains and other fresh and lightly processed plant foods.
