One nutrient-averse writer put Adam Rosante's seven-day green smoothie challenge to the test.

It's embarrassing to admit, but nearly 10 years after college, I still eat like a freshman. Pizza is by far its own food group in my diet-I joke about running marathons as an excuse to eat a whole pie by myself after Saturday long runs. But I'm actually not kidding. In fact, I signed up for my second marathon because I liked being able to eat that much pizza and not stress about the carb intake.

There's a major problem with subsisting mostly on bread, cheese, and tomato sauce, though: I get, like, zero other nutrients in my diet. I may be consuming enough calories, but they're basically empty. And the worst part is, while it may not show up on the scale, I can see the effects in my dull skin, the layer of softness over my abs, and the amount of energy I have when I go running-especially when I'm slogging through marathon training.

I've always known my diet needed to change. I just didn't know how to change it. So when I heard that Adam Rosante, a celebrity strength and nutrition coach, created a (free!) 7-Day Green Smoothie Challenge, I was intrigued. I've paid for and done diet challenges like this before-and failed. They were too intense, too complicated, and too hard to stick to for someone who literally can't cook herself a meal much more sophisticated than plain chicken and rice.

"Every time somebody wants to make any kind of a change, they try to totally overhaul their life," says Rosante. "The research is against you, though; you're gonna burn out and abandon everything. But if you focus on just making one very small change, it's very approachable, and it closes what's called the positive feedback loop, which is basically the time in which you get a positive response from the efforts that you're putting out."

That's the whole premise of Rosante's plan: You swap out breakfast-just one meal a day-for a green smoothie. I liked it because it's not necessarily about slimming down (although it could probably help you lose weight if that's your goal) or "detoxing" or "cleansing." It was about getting more important nutrients into my body so I had more energy to keep up with my workouts.

The smoothies include different mixes of spinach, kale, avocado, bananas, pears, coconut milk, oranges, pineapple slices, honeydew melon, apples, and almond butter. "When you pack this much nutrition-all of these vitamins, minerals, all of the phytonutrients, and the flavonoids that are packed with antioxidants-into a single glass, it impacts you on a cellular level," says Rosante. "This improves health markers across the board. The smoothies are also packed with fiber, which improves your digestion and contributes to healthier weight loss. And they're full of high levels of vitamin C and copper, which aid collagen production and tissue repair-it's also what will improve the quality of your skin tone."

Plus, they're super easy to digest, which is why Rosante champions the liquid breakfast over something like say, an egg white omelet. Not only do the nutrients in smoothies get to where they need to go faster, but drinking them for breakfast gives your digestive system some time off from breaking down heavier whole foods, which conserves energy your body can then use elsewhere, without sacrificing nutrients, says Rosante.

I was sold on the science, but I was less than confident in my ability to pull it off. I know that smoothies are supposed to be the epitome of easy, on-the-go healthy eating, but I've found myself intimidated by them in the past. How do you know what to put in them? How do you know what tastes good with what? Sure, you can blend a couple veggies and some ice in 30 seconds, but is that really enough food for a meal? That's where having actual recipes to follow came in handy. Plus, they all contain six ingredients or less; the whole 11-item grocery list (even with its fancy coconut milk and almond butter) cost me under $60 in New York City.

So each morning, for seven days, I whipped up one of Rosante's smoothies for breakfast. I'm not a big breakfast eater, especially since I work from home-frankly, I'm not a morning person-so having to prepare something for myself when I'm still barely conscious is not ideal. But throwing the six ingredients in the blender couldn't have been easier or more brainless. (My favorite was the Love Child-spinach, pineapple, honeydew melon, banana, and coconut milk-because it was so creamy and smooth.)

My one issue with the challenge was the size of the smoothies-based on Rosante's measurements, they filled about a half of a pint glass. When I added more ice, they were a little bigger, but I still felt hungry about two hours later, which seemed a little quick to be craving another meal. This isn't necessarily a bad thing though, says Rosante. "These recipes are very low in calories, but very high in nutrients-so you're getting all of the nutrients you need at breakfast for not a lot of the calories," he says. "If you're used to having a bigger breakfast, you're most likely gonna be hungry a couple of hours later and that's okay-you can have a healthy, midmorning snack." You can also add protein pre-workout or if you're craving a little more substance. (I added a teaspoon of whey protein powder on a couple of the days, which helped).

While I didn't notice an immediate effect, by day three, I could swear that my skin looked a little brighter and that I definitely had more energy. (I did try to eat generally healthier at all my other meals, too, though Rosante says you can eat however you want the rest of the day; I made it to day five before ordering myself a pizza for dinner.) By the end of the week, I actually do think I looked a little leaner, an added bonus Rosante promised but that I didn't expect.

And you know what? I think this challenge is something that could end up sticking around. Compared to other diet challenges and plans I've tried, this one was totally easy to incorporate into my life-and I didn't feel like I was sacrificing anything to reap the benefits.

"I want people to realize that being healthy is simpler than you think," says Rosante. "We love to overcomplicate the hell out of things, but something as simple as swapping your typical breakfast for a green smoothie can be the one change that eventually opens the door to change everything for you."

Hi, my name is Sara and I'm 40 years old. My body transformation journey started when I came across Emma's story. Emma's husband left her for a younger woman, which sent her into a downward spiral that made her gain a lot of weight very fast. Luckily she discovered an amazing workout program that allowed her to achieve the best shape of her life. Read her story here >>

Hi, my name is Kate and I would like to share my story. Up until about 2 years ago, I was 30 pounds overweight. Over the years I had followed many different diet plans, but failed every single time. I was "blessed" with a pear shaped body and no matter what i did, I always retained lots of stubborn fat in my lower body. Everything changed when I found the right diet program. My story is here ==>
