Though it's been months since its debut, the book continually spikes on Amazon's Movers and Shakers list — its roundup of the top-selling products across the site — and it's currently listed as the No. 1 bestseller in the Diet Books category. Naturally, this begs the question: What's all the hype about? Aside from the famous author — and the fact that the title suggests fixing a problem just about every human struggles with (just look at search traffic for "flat belly" and "flat stomach" exercises). Is it all just marketing hype?
Our muscles are habitual of storing a kind of carbohydrate known as glycogen. This stored carbohydrate is only consumed when our body does some extra exercise. When we get rid of carbs, we can actually access this stored fuel and consume it off. For this avoid consuming carbs after lunch and substitute with low-carb food so that no new fat is stored.
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.
Whereas many beverages can increase your waistline (see above), there is one that is guaranteed to trim your tummy: water. Drinking plain ol' H2O works because staying fully hydrated tells your body it's okay to release any extra water it's retaining, decreasing the accompanying bloat. Plus, drinking water has been proven to reduce cravings for sweets, lower your appetite, and help you feel satiated faster.
Simply put, artificial sweeteners cause belly fat. A 2015 study in the Journal of the American Geriatrics Society found that increasing diet soda intake is directly linked to greater abdominal obesity. In the study of older adults, researchers found those who drank diet soda each day experienced more than triple the increase in waist size over the course of nine years, so put down the Diet Coke and don’t even think about reaching for some Equal to put in your morning coffee.
And as a little extra bonus, we’ve reduced your added sugar intake to essentially 0 grams per day. With some clever tricks (like adding bananas to sweeten your oatmeal) and by completely eschewing ultra-processed foods (which provide the average American with 90 percent of the added sugar you’d consume in a day), cooking at home not only helps you lower your calorie intake, but also helps you to cut that inflammation-inducing added sugar. So grab a pen and paper, get to the grocery store, and start cooking! You’ll start feeling slimmer, less bloated, and have more energy in no time.
