How is this possible?
“Little Fat Loss Ingredient Tweaks!”

What is a Little Fat Loss Ingredient Tweak?

I call them LFITs for short. . .

An LFIT is an ingredient that tastes the same as a higher calorie ingredient, is roughly the same size, but
has fewer calories.

And my cookbook is filled with them.

For example. . .

In my 4 cheesecake recipes
(yes, there’s 4):

Instead of normal cream cheese, I use another kind of store bought 'cheese' to replicate the flavor and texture, while decreasing a TON of calories and increasing protein.


It tastes unbelievably close to calorie-dense normal cheesecake without making your waist bulge.

Another Example. . .

In my Penne Alfredo Recipe:

Instead of waist-expanding alfredo sauce, I use a very specific kind of yogurt, a “yeast” (that’s right), and another LFIT to replicate the creamy, hearty, thick delicious flavor of alfredo sauce....

Without the high-fat calories.


It tastes nearly the same as any normal alfredo.

And that's just 2...

Every recipe inside is tweaked just like that:
to decrease the calories you consume, while keeping the flavor!

You can eat many of the
ingredients individually

For example: The peanut butter substitute I use in a few recipes. . .

It tastes just like normal full-fat peanut butter, but has far fewer calories.

Grab a spoon and eat it all by itself instead of normal peanut
butter and your PB craving will be satisfied.

Or, you can grab a knife and spread that very same peanut
butter across toast. . . or put it in Pad Thai . . .
or keep eating it by itself!

There’s so many delicious LFITs
inside such as. . .

A Chocolate Chip

A Caramel

A Cheese

A Bacon

An Egg


A Potato

A Rice

And that’s just scratching the surface!

Now, when you see these ingredients for the first time you may say, “huh? Icky. These are odd...” But I urge you to try them!

Because, when you taste them, you’ll wonder why you haven’t been eating these foods instead your entire life!

They taste nearly identical to normal food most people buy, but have way fewer calories!

They’re inexpensive too. Which is why I’m going to tell you where to get them in the
store, and exactly what to look for on labels!

Forcing yourself to stop eating what you've enjoyed your entire life, is impossible to keep up long term. That's why my team and I made this book. With it, you "force yourself" to change nothing.

The Little Fat Loss Ingredient Tweaks (LFITs) inside each recipe let you eat food you love that has all the same great taste you love. All while consuming far fewer calories than you did before.

Bonus #1
Full-Day Meal Plan

Want to eat every meal, right out this book — every day — and simultaneously hit a weekly fat loss goal?

For a limited time, you can.

Included in your cookbook, you’ll receive a meal plan that lets you eat every single meal out of this book.

It will feel “wrong”... Eating these recipes.

Everything inside is engineered to taste delicious, while keeping the calories you consume unbelievably low.

And yet, if you use your meal plan and eat every meal out of this book, you’ll lose fat on a regular basis while eating delicious food!

Bonus #2
Nutrition Facts Shopping Guide

Did you know, food companies pay "slotting fees" to place their food in the "best place" on the shelves (eye level)? It's true. Those same companies almost always have the lowest quality, least healthy, & highest price food.

The Nutrition Facts Shopping Guide bypasses "slotting fees".

For every type of food in this cookbook, we show you actual nutrition labels so you know exactly what to look for and where to find them. Not to mention many of the ingredients we specify are less expensive.

Here’s what real people are saying
about what they’re eating

This cheesecake addict says thank you.

I have a cheesecake problem. When I see cheesecake, I HAVE to eat it. I have no self control. When my bf and I shop, he steers the cart away from the bakery. All 4 of ur cheesecake recipees literally cut my binge calories in half. Taste great! I still don’t have self control, but thanks to your book, it’s ½ the issue it used to be. This cheesecake addict says thank you.

This makes chicken exciting again

I’ve been eating chicken every night for 10 years. It got boring 5 years ago. This makes chicken exciting again . Tried half the chicken recipes so far. They’ve all got a lower more calories than what I’ve been eating, but are like 10 times tastier.

The ingredients are dead simple

Getting this made me start taking my nutrition seriously. I’m not really good at cooking. So far though, everything I’ve made from your cookbook has tasted great. The ingredients are dead simple, and the directions are very easy to understand. I can’t wait to try more recipes.

...It’s kind of a mini miracle

My son asked me to buy this for him. He loves it. And I love the love the desserts.

I definitely have more energy.

I eat the muscle griddle in the morning before I go to work. It takes more time to make than hitting a drive through but the upside is, and it's a big upside for me, I definitely have more energy for the gym which lasts until work.

Your veggie burger & normal burgers kick but

I don't like veggie burgers, but I like this one. I have a busy schedule,( as I'm in med school & have literally zero time). Most of your recipes are pretty simple, which means I don't have to spend a lot of time prepping stuff, and can try to multi-task at the same time! Thank you.

Wife kept saying, I can’t believe it’s 368 calories!

Last Saturday, I made a batch of your cheeseburgers. The whole time, my wife kept saying, "I can't believe it's 368 calories." I too, echo her thoughts.
