In this book, we look at all of the ways you can improve your own gut health, starting with the food you eat. My diet recommendations, meal plans, and recipes will help feed and protect your gut microbes. And we look at themanyother steps you can take to support your beneficial bacteria, from avoiding unnecessary antibiotics to changing the way you think about dirt and germs. Even the choices you make about how you bring your children into the world can have an impact on your family's microbiomes.

Maintaining your weight loss is all about balance, you should try to follow the 80/20 rule. Focus 80 percent of the time on eating healthy, belly-friendly foods that shrink the waistline and fight inflammation. Then 20 percent of the time, you have room to veer off track a bit. This 20 percent is your splurge. You may choose to have one day a week where you have a splurge meal, or you may opt for a small snack twice a week where you don’t exactly make the healthiest choice.
HOW TO MAKE IT: Cut up two 4-oz portions of pork into cubes along with 1/2 cup diced onion. Heat a tablespoon of canola oil in a pan over medium-high head. Add pork and onions and saute for 3 minutes. Add a 1 cup of frozen peas and carrots, and 1/4 cup frozen corn. Move veggies to the side, and crack two eggs on the other side, whisking to scramble. Add in 1 cup rice, 1 tbsp soy sauce, a splash of sesame oil if you have it, and fry together for another minute. Makes 2 servings.
For your dinner tonight—as well as for lunch and dinner for the next couple days—you’ll be making a super simple roasted chicken breast with roasted veggies and quinoa. Chicken is a versatile, lean protein that’s rich in selenium—a mineral that keeps your skin glowing and your metabolism running properly. Quinoa is an ancient grain that’s touted for its micronutrients, anti-inflammatory phytonutrients, and antioxidants, like fat-burning quercetin. And, of course, we’re getting in a rainbow of veggies to reap the unique properties of each.
"Eating portion-controlled meals that include whole-grain foods and monounsaturated fats (MUFAs) throughout the day is the best way to eat for a flat belly: People who eat whole grains lose more abdominal fat. And making most of the fats you eat MUFAs reduces ab flab, research says." —Keri Glassman, RD, author of The O2 Diet and The Snack Factor Diet

The thyroid gland is best known for its metabolic function affecting weight. Estrogen dominance renders the thyroid hormones dysfunctional, causing your body's metabolism to slow down. The resulting condition is called relative hypothyroidism. In addition, the changes in your body's blood sugar levels—some of which occur naturally with age and some of which are due to a hormone imbalance—are also linked to weight gain. As the body's progesterone production decreases with age and estrogen becomes dominant, your body releases insulin more rapidly and more often. When fluctuating hormones unnaturally stimulate insulin release, you get hungry faster and will often crave sugar. In fact, these food cravings can sometimes be uncontrollable, and people who are estrogen dominant tend to consume more sweets even when they aren't truly hungry. As a result, they ingest more calories than their bodies require and pack on even more pounds.


Adequate sleep plays an integral role in our weight. This is because our metabolism dictates everything from the rate we burn calories to when and where we store fat. And your metabolism is simply your biochemistry / hormone balance. For this reason, when we don’t sleep the body doesn’t release as much fat burning HGH, and conversely it releases more of the belly fat stress hormone cortisol as well as an appetite enhancing hormone called Ghrelin. Be sure to get your shut eye. 8 hours a night is preferable, but 7 will suffice.

It's not just about weight loss. Having great gut health is linked to good health throughout your body. Scientists in this rapidly growing field are finding connections between gut microbes and the immune system, weight loss, gastrointestinal health, allergies, asthma, and even cancer. With every study that's published, scientists become more convinced that having a healthy gut leads to having a healthy body.
Bring your hands into prayer pose. Lunge forward with your left leg and bend your knee about 90 degrees, keeping your back leg straight. Brace your abs in tight to your spine and rotate your upper body to the left. Keep your spine long as you lean over your left leg and press your right elbow into the outside of your left leg. Turn your head to look up toward the ceiling over your left shoulder. Hold for 10 long, deep breaths and then untwist and return to standing. Repeat on the other side.

Cutting the amount of sugar you eat is one of the quickest and easiest ways to flatten your belly, especially if you replace that unhealthy added sugar with more fiber. In a review of 68 clinical trials and studies, New Zealand researchers reported in the British Medical Journal that increasing sugar intake meant increasing body weight while reducing sugar meant reducing body weight. Similarly, increasing fiber is another way to keep your belly lean. In a study of 1,114 people over five years, researchers reported that for every 10 grams of soluble fiber people ate, their belly fat accumulation was reduced by nearly 4 percent—even if they did nothing else to lose weight.

Your phone, tablet, and television may be affecting your waist size in more ways that one. Obviously if you’re sitting on electronics then you’re not moving around and burning calories. But the effects go beyond just energy. Blue light from electronic screens can disrupt your circadian rhythms; so our addiction to electronics is reducing our sleep as people favor Netflix-bingeing to bed. Both of these effects have been linked to higher levels of belly fat. These 21 other terrible habits will make your belly fat worse.
The good news, according to Weltman, is that high intensity — the level at which you feel the effort and can no longer hold a conversation — is different for each person. "You may have to run to get to that level, while someone else may just have to jog or walk," he explains. "It all depends on your level of fitness, but the great thing is, you can do it whether you're a competitive athlete or just starting out."
Yep, you read that right. High-water foods like fruits and veggies will fill you up faster, says Jaclyn London, M.S., R.D., C.D.N, Nutrition Director at the Good Housekeeping Institute. Start your meal with soup, salad, or her favorite pick: Pre-dinner sliced crudité and spicy hummus. The combo of capsaicin (a spice in hot peppers) and the chickpeas' soluble fiber can help curb hunger.

"Refined grains like white bread, crackers, and chips, as well as refined sugars in sweetened drinks and desserts increase inflammation in our bodies. Belly fat is associated with inflammation, so eating too many processed foods will hinder your ability to lose belly fat. Natural foods like fruits, vegetables, and whole grains are full of antioxidants, which have anti-inflammatory properties and may therefore actually prevent belly fat.”
The external obliques are the V-shaped muscles running diagonally down your sides that, along with the internal obliques underneath them, help you rotate your spine when a Ryan Gosling look-alike walks by. The rectus abdominis, meanwhile, is the straight-down-the-center muscle which, yes, can make you appear to have a six-pack if you have a seemingly single-digit body-fat percentage like Ryan Gosling's. The one remaining ab muscle, which Dr. Herrera's surface EMG won't be picking up, is the transversus abdominis. The deepest-down of all, it does a complete wraparound of your midsection and pulls it in like a corset.
Don’t fret about having to cook tonight, this sheet-pan supper is super simple. You’ll be making a piece of sockeye salmon (or wild salmon of your choice, just not farmed Atlantic) with roasted asparagus and brown rice. An important part of the flat-belly diet is getting in those anti-inflammatory, brain-protecting omega-3s that will help you lose weight and improve your health, and salmon is teeming with them. Plus, you’ll get in a serving of prebiotics via the asparagus to start healing your gut and decrease the inflammation that’s causing weight gain.
But regardless of how tight your ab muscles are, they can't erase belly fat that lies above (subcutaneous) or below them (visceral fat). Those you'll have to burn off—and according to Olson's research, the best belly fat-melting method is Tabata intervals. Maximum-effort cardio intervals raise your level of adrenaline, the fight-or-flight hormone that's the secret sauce to burning fat.
Just like vegetables, this can be as simple or as complex as you want it. Maybe you’re just making sure there’s a protein source at each meal (if it was lacking before). Maybe you’re figuring out rough portion sizes. Maybe you’re taking it to the max and actually weighing your food. The point is, you should be including it throughout the day and week.
“The plank is a favorite, but we take it to another level opening and closing the legs like scissors while at the same time raising and dropping the hips! So not only are you strengthening the core but also timing the hips, thighs and waist. [We also do] the trunk twist along with a back row using the bands. The benefit of this exercise will give you flat abs and coke bottle obliques while removing those fat handles from the back and arms.”
