The Sweet Potato Diet Review – Does This System Actually Work?

I’m really excited to write this Sweet Potato Diet review, and not just because it’s made a difference in my own health and wellness.

For the last two years, I’ve spent a lot of time on my body, figuring out how to get it to the healthiest, most loved state I can possibly create.

I started at 268 pounds, got down to 190-something, and then fluctuated quite a bit. Most of that came off using either keto, whole foods or a raw diet with lots of HIIT exercise.

But, I hit a plateau. While I loved eating keto and felt better than I ever had prior, my body wasn’t anywhere near where I wanted it to be. What to do?

As I live most of my life in a state of, “Let’s see what magic appears,” I waited. Shortly after deciding to wait and see, I was offered a review copy of this book from NetGalley, and this Sweet Potato Diet review was borne.

Short version? I highly recommend The Sweet Potato Diet with some caveats – you’ll really only use this for the structure of the diet, not the recipes.

Long version? Let’s get to it.

The Basics of The Sweet Potato Diet

The book simply and concisely describes a carb cycling diet. For those unfamiliar with carb cycling, it’s process to introduce more carbs on some days, and less on others, to shock your body into losing weight.

There’s a lot of science and data about carb cycling, as there is keto. I’d yet to use a carb cycling program, but had read lots of research on it. A few authors and fitness trainers had also offered me their programs in the past, but they were too convoluted for me to put into place.

For me, that’s saying a lot. I routinely read scientific journals for fun and my work. If I feel a process is made too complex for daily use, however, I’m out.

The Sweet Potato Diet though was simple yet offered me more than enough information to show me it was worth trying. Add to the author’s personal experiences with the diet and I was sold.

Do I Have To Eat…?

I was quite concerned about this diet, however.. I really didn’t want to eat the things that I knew already added inflammation in my body from all my other diet experiments.

In my case, that’s all grains, dairy, sugar and most fruits.

So, to put anyone else’s concerns to rest: you don’t have to eat any of these things. In fact, Michael Morrelli advises staying away from all of it. Phew!

The diet does have you eating some form of sweet potato at least four days a week, as well as healthy amounts of fat, vegetables and protein. You can choose the protein source, although meat is highly favored over vegetarian or vegan options.

Which isn’t to say you can’t use the Sweet Potato Diet and be vegan or vegetarian – I’m sure you could – it just might prove difficult.

On the days where I chose to eat vegetarian or vegan, my protein came from Vega Sport Performance Protein. I might have been able to figure it out with a high-fat nut (like macadamias) if I wanted to.

Day To Day Eating

I knew I’d have to share some of the processes of the diet without actually revealing the details that might stop someone from buying the book as I wrote this Sweet Potato Diet review.

But, how?

I fought with this one quite a bit, and decided in the end I’d share the basic structure. So, here goes.

The diet is based on a four-week cycle: three weeks following a specific daily allocation of carbs followed by seven days straight of the same daily carb allocation.

Each day of the first three weeks requires different macronutrients. To keep track (the most “challenging” part of the diet), I created a simple spreadsheet and printed it out so I knew what day was what. Easy peasy.

You’ll eat five times a day (no exceptions), the same macronutrients each time. Measuring consists of using a very simple process, specific to your own dietary needs.

Calorie-free drinks and seasonings are unlimited on the plan, plus a required amount of water per day. In my case, that was three liters. (As I’d already introduced this practice, it didn’t change anything for me).

Food Prep

I’ll be honest – there’s a fair amount of food prep with this diet. The author suggests hiring someone to do food prep for $15 an hour – an excellent idea.

In my case, I don’t have room for a week’s worth of food in my fridge. I travel full time and more often than not share space with others.

So, I decided I would do my food prep once a day. This worked well for me.

I would start my day by cooking one large portion of a dish that fit my macros for the day and put the remaining meals in the fridge for later.

Since creating five servings of any one recipe is a bit challenging, my last meal was often just cut up vegetables and portable proteins and/or fats. Think beef jerky, hard boiled eggs, or leftovers from some of the baking in the higher carb days.

It took me, on average, 30 minutes every morning to make my meals for the day.

What About the Recipes?

Unfortunately, a lot of the recipes in the version of the book I was given access to (prior to publication) weren’t usable. I only discovered this as I went to make them, so it was a bit disappointing.

I did share this with the publishing company, and hopefully this was all fixed.

As well, I couldn’t find a lot of recipes that fit the macros I needed for most days. So, for instance if I needed to eat one serving of protein, one of vegetables, none of fat and two of carbs – I couldn’t find a recipe that fit this criteria.

And if you’re on a really low carb day? Fuggetaboutit. There’s nothing. You’re on your own.

Now, I realize this Sweet Potato Diet review is about the book and the recipes – and why would they include recipes that don’t include sweet potatoes?

Here’s my take on it: if you’re going to have me only eating sweet potatoes for carbs (I love it, yes I do), AND have me on days where I eat zero sweet potatoes… I want recipes for both.

Like I said, there just aren’t any in this book.

Luckily, my experience with eating keto had me well covered here.

If there’s any demand, I’ll happily write an article with all my favorite keto recipes that I used during this Sweet Potato Diet review process.

What I Love About This Book

There’s a lot I loved about this book.

Firstly, it’s that I read it in one sitting. Which isn’t to say it’s a basic book. It’s not. It’s that I could get started right away with all the necessary information at my fingertips. Yes! Thank you.

Next up? The tone of the book. I like to think of myself as an intelligent woman, yet I’ve read countless health and wellness books on similar subjects where I felt patronized, spoken down to, or like I was reading their “prove-it-to-the-world” manifesto that they’re King of the World.

No thanks.

I also hate it when I read a book whose author pummels me with the information they’re trying to get across. A few books I’ve read of late through NetGalley have fit this category of reading.

None of this applies, thankfully, to this book and my Sweet Potato Diet review. Yay!

If anything, I felt like this book was a dear friend talking to me about their weight loss experiment, sharing what worked and what didn’t, and then giving me concrete, usable information so I could match their results.

This tone

I Wish There Was More Of…

Perhaps not more of, but rather, a bit more fleshing out.

For instance, if I wanted to use my own recipes, I was out of luck. There’s no macronutrient profile given in the book to say, “this is how many carbs are in this,” or how it was determined with the recipe creation.

Now, I realize the measuring of macros in this program is more unusual than most programs, and it can’t really translate to the recipes (if I were to get technical).

I was willing to forgive this though, and use general macros. Still, it makes me wonder if I’d have better results if I were more precise with my measurements. Only time will tell… and I’ll add to this when I get those numbers.

What I’m trying to say is this: I wish there were some way for me to determine the protein, fat, and carb counts of my own recipes so I knew if I was within my macros.

As an example: if you sign up for the MorrelliFit newsletter, you’ll get one or four Sweet Potato Diet recipes. Awesome, right?

Well, if you’ve purchased the book already, not awesome. The newsletter is intended to get interested folks to buy the book, which I understand. But if you have already, oops.. there’s no listing of the carb, protein or fat macros for any of those recipes.

Now, I can kind of figure it out… there’s one amazing sweet potato hummus recipe that I’d categorize as one maybe a two carb portion, and possibly half a fat portion. But, which one is it?

I Wish There Was Less Of…

The only complaint I have of the book is that a few things get repeated throughout. I understood the macro measurements the first three times, but started to roll my eyes at around six or seven.

Biggest Drawbacks

Here’s what I struggled with the most, and it wasn’t anything to do with the book. It was in the implementation, for me.

As I’ve shared already, I’ve eaten keto for almost two years, with a few small deviations for a week or two here and there.

Keto, if you’re not aware, is a diet where you eat in excess of 70% of your diet from healthy fats. Again, I loved it, but it just points to my ability to adhere to a very strict and challenging diet.

When I ate keto, I was very rarely hungry. If anything, I forgot to eat most days and needed a reminder alert on my phone.

While working on this Sweet Potato Diet review, I struggled big time with my low and no carb days. I needed more fat and protein than the allotted amounts at least once a day. Which I found odd, considering I’ve eaten way fewer calories than what’s prescribed in the Sweet Potato Diet most of the last two years.

If anything, I’m eating almost double the calories. So, you’d think I’d be satiated? And yet…

I’m only a few days in, so I can’t really say for sure if this is just an adjustment, or, if it’s just not working for me. I’ll update with more results over the next month with concrete data as I move through this process.

Another Drawback?

I was given two different review copies through NetGalley, both electronic.

Sadly, both versions had the same errors in a quite a few of the recipes. I couldn’t make a few that I really wanted to try due to errors and obvious lack of data.

Hopefully this was fixed prior to printing.

One More Thing?

Often in review copies of diet books, there aren’t any before/after pictures or stories.

Having said that, usually there’s a marker within the book to show that’s where it’ll sit after publication.


I also searched online for these sorts of stories, hoping to see results.


Normally I wouldn’t find this terribly odd, but, the book mentions the 200,000 people MorrelliFit has helped over the last few years… so….

Did I Lose Any Weight With the Sweet Potato Diet?

A lot of folks will skip to this section, understandably.

I plan on sharing my measurements and details on a weekly basis for a full cycle (a month), to see if this diet helped or hindered my stalled weight loss.

I’ll post those details in this section as soon as I have them.

My initial experience has been some hunger on low and no carb days, and extreme bloating – although this might be from undercooking some cabbage curry I made.

The Bottom Line on This Sweet Potato Diet Review

I love this book. The tone, feel and information served me perfectly, and I was able to fill in the blanks I needed to.

Did I want more from the book as I wrote this Sweet Potato Diet review? Yes. Was it lacking a bit in details for someone experienced with very strict diets? Yes.

At the same time, this book gave me the clearest, most concise explanation of carb cycling that I’ve found. It helped me jump on board immediately – a huge plus.

Do I recommend the book? Like I said at the start – a definite yes with caveats. Stay tuned for more about whether or not it helped me lose weight.
