That's exactly what happened when last summer I shared Zero Belly Diet with a test panel of more than 500 people, some of whom lost as much as 16 pounds in just 14 days, and up to three inches off their waist. The secret to Zero Belly Diet is the new science of nutritional genetics, the study of how our genes are turned on and off by the foods we eat. Simply making a handful of tweaks to your diet and lifestyle can help improve your gut health, dampen inflammation, turn off your fat genes and start your body shedding fat—in particular, belly fat—almost automatically.

HOW TO MAKE IT: Preheat oven to 350 degrees. Cut a 1 pound, small spaghetti squash in half and scoop out the seeds with a spoon. Place in an oven-safe baking dish, flesh-side up, and pour about 2 tablespoons of water into each half. Cover with aluminum foil and bake for 50 minutes to an hour, or until tender. In the meantime, pour a serving of marinara sauce into a small saucepan along with 6 of the mini meatballs to begin to heat up and defrost. Cover. Once the squash is done, pour out the water and use a fork to scrape long, spaghetti-like strands from the flesh onto your plate. Save the other half of the squash for lunch tomorrow.
If you're after a sleeker middle, add dairy to your diet. Research shows that its proteins increase satiety and cause you to eat less. My choice: homemade Parmesan crisps. Preheat oven to 350; line a baking sheet with parchment. Divide 2 cups grated Parmesan into 2-Tbsp. portions. Form each into a small pile and press with the back of a fork. Bake until melted and flat, 5 to 10 minutes. Transfer to a paper towel-lined plate. Serve with chopped cooked vegetables (I love spinach, squash or eggplant).
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.
