The book itself doesn't get tediously microbiome-focused, though. The first section of The Lose Your Belly Diet sets the stage, then part two goes into which foods can give you that healthy mix of gut bacteria. Part three focuses on other ways to boost your stomach's microbiome health (avoiding antibiotics when you don't need them, exercise, and what probiotic supplements to take, namely), while part four gets actionable, providing a diet quiz, recipes, and a meal plan.

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.

This way they’re more readily available, and you have no excuses to grab a bag of chips, right?  Katie Cavuto, MS, RD, the dietitian to the Philadelphia Phillies and Flyers, likes having washed and prepared cucumbers, peppers, sugar snap peas, and carrots in the front of the fridge so they aren’t overlooked. Bananas, apples, pears and oranges fare well as sweet snacks and should be kept on the counter where you can see them.

Why: "Oats fill you up with fiber without added sugar, like most highly processed cereals," Glassman says. "Nut butter provides healthy fat that will keep you satisfied, but won't hold onto water like sugary and salty packaged foods. (That being said, be sure to check labels and pick items with no added salt sugar!) Berries fill you up with fiber and water volume without adding a big carb load to your morning."

Hold a resistance band taut between your hands and lie on the floor face up, with legs extended and arms overhead. Pull abs in, tuck your chin, lift arms toward the ceiling, and roll head, shoulders, and torso up and over your legs as far as you can. Keep heels firmly on the floor and reach your hands towards your feet. Pause, then slowly roll back down. Do 5 to 8 reps with 30 minutes of cardio 5 to 6 times a week.

For test panelist June Caron, incorporating fresh produce like avocados was a life-changing lesson from Zero Belly Diet. The 55-year-old lost 6 pounds in the first week on the program. "Learning to eat real, chemical-free, fresh foods has been the best thing that ever happened to me. I am never hungry. And the weight just keeps coming off!" Glowing skin, healthy nails, and better sleep were Zero Belly bonuses, June said. "I'm well on my way to getting my sexy back. Everyone says I look much younger!"
A recent study revealed that when women who were unhappy with their weight completed a one-time, 15-minute writing exercise about an important personal issue, they went on to lose at least three pounds over a three-month period. On the other hand, their counterparts who wrote about an unimportant topic gained three pounds, according to Cheryl Forberg, author of A Small Guide to Losing.

Avocados are a double-whammy to belly fat. First, they're packed with heart-healthy monounsaturated fats that dim your hunger switches; a study in Nutrition Journal found that participants who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterward. Second, unsaturated fats like those found in avocados seem to prevent the storage of belly fat. (These creative ways to eat avocado will help you up your intake.)
