“Dave, I can’t take it anymore,” my friend Marissa told me last week. “Every time I buy a diet book, there’s just too many rules. No carbs. No dairy. No grains. No beans. No fun!”
“No worries” I told her. “I’ve got the solution.” I handed her a copy of my new book, Zero Belly Smoothies.
When you begin drinking Zero Belly Smoothies, you’ll quickly put your weight-loss journey on autopilot—it’s easy, simple 60-second nutrition. You simply need to ask yourself three questions:
WHERE’S MY PROTEIN?
WHERE’S MY FIBER?
WHERE’S MY HEALTHY FAT?
Put together a drink that provides all three, and I guarantee you’ve got a line on a leaner, healthier body that’s functioning at the peak of its genetic programming. Hitting all three in one sip means you’re feeding your muscles; eating a slowly absorbed, hunger-controlling meal; maximizing the absorption of nutrients in your food to positively influence your genetics; and striking a major blow against cholesterol and elevated blood sugar. The Big Three will also help crowd out refined carbohydrates, saturated fats, added sugars, and additives.
The result is rapid weight loss—guaranteed. Consider Jennie Joshi, a mom of two, living in Morristown, NJ, who would avoid walking past the full-length mirror in her home because, she says: “I hated the way I looked. I wanted to see the old me.”
In just four weeks, Joshi lost 11 pounds. Amazed at the results, she kept going, adding exercise to her weekly routine and simplifying her daily diet with the touch of her bye-bye-belly button. In all, she lost 26 pounds, dropping from 176 pounds to 150–and now she fits into a size 4 dress.
Here are the three reasons why Zero Belly Smoothies are so effective.
Zero Belly Smoothie Secret #1
Protein helps you burn fat in three ways. First, it’s the building block of muscle, and you already know that muscle burns fat. Feeding your muscles helps them grow and fight back against the forces of fleshiness.
Second, the very act of eating protein actually burns calories. It takes more than a kiss from a princess to turn a frog—or a cow, pig, or chicken, or a nut or bean, for that matter—into a human. As much as 20 to 35 percent of the calories you eat in the form of protein are burned up just digesting the protein itself. (Carbs and fat burn up no more than 5 to 15 percent of their calories.)
And third, protein keeps you fuller longer—in part because that intense digestive process means your body perceives you as being satiated. In a 2013 study published in the journal Appetite, women were fed low-, moderate-, or high-protein afternoon snacks. Those who ate the most protein had the lowest levels of hunger and waited longer before they chose to eat again than those who ate lower-protein snacks.
Zero Belly Smoothies get their protein primarily from vegan protein powders, but oatmeal, spirulina powder, and nut butters are also excellent, smoothie-friendly sources. My favorite brands of protein powders, which you can click to buy right here, are Sunwarrior Warrior Blend Raw Protein Powder, Vega All-In-One Nutritional Shake, and Garden of Life Raw Protein.
Zero Belly Smoothie Secret #2
Fiber plays a number of additional roles in keeping us slim, but the most intriguing is its ability to suppress appetite. In spring 2014, an international team of researchers identified an anti-appetite molecule called acetate that’s naturally released when fiber is digested. Acetate then travels to the brain, where it signals us to stop eating.
Some scientists believe that the dramatic reduction in fiber in our diets is perhaps the No. 1 factor in our obesity crisis. Professor Gary Frost from the Department of Medicine at Imperial College in London, who was part of the team that put together the acetate study, estimates that, thanks to food processing, the average Western citizen now eats about one-seventh as much fiber as humans did in the Stone Age. With Zero Belly Smoothies, you can get a third of your day's worth in one glass.
Zero Belly Smoothie Secret #3
I know it sounds counterintuitive, but if you want to burn fat, you need to eat fat—regularly. A Zero Belly Smoothie needs to contain at least one of the following ingredients:
MONOUNSATURATED FATS: olives and olive oil, nuts (including peanuts) and nut butters, avocado, dark chocolate (at least 72 percent cacao)
POLYUNSATURATED FATS: sunflower seeds, sunflower oil, sesame seeds, pine nuts
PLANT-BASED SATURATED FATS: coconut (no sugar added), coconut oil (not hydrogenated)
OMEGA-3 FATTY ACIDS: flaxseeds, walnuts, chia seeds, hemp seeds
The fact is that eating a moderate portion of unsaturated fats, like the kind found in olive oil, avocados, and nuts, can ward off the munchies and keep you full by regulating hunger hormones. A study published 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. Moreover, increasing the amount of omega-3 fatty acids in your diet while reducing omega-6 fats (found in vegetable oil and foods fried in that oil) has proven to improve metabolic health and reduce inflammation.
