Forget about calorie cutting, 15-day resets, and rapid weight loss programs.

What if you could change your eating habits to lose fat sustainably and keep it off?

What if you could stop getting stuck at a certain weight, no matter what you do?

What if you could finally take control and get on the path to better health?

Hi, I’m Brian Stanton, author of Keto Intermittent Fasting and founder of

I’m a big believer in putting health #1. It’s been that way since my early twenties, when I used an ancestral diet to heal my IBS. 

Caring about your health is crucial, but it’s not everything. You can care about your health, but still struggle with weight, energy, mood, libido—you name it.

The other day, I received an email from a reader. He said his doctor was recommending weight loss surgery, but that he’d rather do it the natural way. 

I pinged him back with a few questions:

  • What’s your definition of health?
  • What are your primary health goals?
  • How would life be different if you achieved these goals?

Here’s what he wrote back:

This is someone who truly wants to get healthy, but hasn’t been able to. 

 And he’s not lacking motivation. Hiking with the family, picking up his kid, better sex drive, better mood, less pain, feeling the energy to hop out of bed and enjoy life. 

These are fundamental human wants. And they boil down to one simple want: To be healthy and happy. 

But even with this motivation, you can get stuck.

Stuck at a certain weight for months, no matter what you do…

Discouraged because every time you lose weight, you gain it back again…

Disheartened by your lack of energy for activities with friends and family…

Just wanting to fit into your favorite jeans without a struggle…

Frustrated because you’ve tried every conceivable strategy (including cutting calories) to get healthy… And none of them have succeeded.  

Wherever you turn, the prescription for weight loss is always the same: Move more, eat less.  

You’ve tried moving more and eating less. And maybe you lost a few pounds, felt better, and even declared success.  

But then something derailed you. And most (or all) of your progress vanished. 


Why Most Diets Fail

Ever watched The Biggest Loser? It’s a show about people losing weight, usually successfully. One man, Michael Ventrella, lost 264 pounds! 

But here’s what the show doesn’t tell you. After the cameras switch off, the participants inevitably regain the lost weight.

The Biggest Loser Diet is not a sustainable diet. It fails for the two reasons most diets fail:

  1. Restricting calories slows your metabolism
  2. Bad habits aren’t uprooted 

Let’s deal with these one at a time. 

1: Calorie Restriction Slows Your Metabolism

Most diets, including the Biggest Loser Diet, revolve around calorie restriction. The premise is simple: Less calories in, less weight gained. 

Calorie restriction doesn’t just mean skipping dessert. It means eating 25-50% fewer calories than your body requires day after day, month after month. 

In the short term, it works. Sure, you might be cold, hungry, and fatigued—but at least you’re shedding pounds!

But after a while, your metabolism (the rate at which you use energy) gets the memo. “Okay,” says your metabolism, “if you aren’t gonna feed me enough, I’m switching to low-power mode.” 

In low-power mode, you feel sluggish, unmotivated and blah. And weight loss stalls, because now you’re burning fewer calories at rest.  

But it gets worse. Once low-power mode gets activated, it stays activated. 

One study found that Biggest Loser contestants still had depressed metabolisms six years after the show.(1) Six years!

The punchline is: If you chronically restrict calories, you’ll lose weight, but you’ll also slow your metabolic rate. Then when you start eating normally again, the weight comes roaring back. 

So calorie restriction is a huge reason why most diets fail. But there’s an equally important reason…

2: Bad Habits Aren’t Uprooted

Bad habits are hard to break. Even when they’re self-destructive. 

In terms of diet, we’re talking about late night snacking, ice cream indulging, having a few beers, ordering takeout Chinese food, or just plain old overeating. 

We’ve all been there. We know these behaviors aren’t improving our health, but they’re so automatic they happen anyway. 

That’s what a habit is. An automatic, unconscious behavior. 

And once these behaviors are rooted, they’re SUPER hard to uproot. 

Once rats associate pushing a lever with a sugary reward, they’ll go on slamming that lever— even after the sugar is removed.(2) That’s the power of habit. 

We aren’t rats, but the basic principle still applies. 

You know that certain eating behaviors aren’t moving you in the right direction. Sure, it tastes good in the moment, but later you feel physically and emotionally lousy. 

In the long run, the rewards don’t justify the consequences. You know this. Yet the habit persists. 

Can you overcome bad habits with willpower? 

Maybe temporarily, but it’s a losing strategy. Willpower is limited—and when it runs out, the bad habit returns.

Besides, you’ve tried the willpower method. It doesn’t work.

So, what does work? What do you need to do? 

Uproot your bad eating habits.  

Most programs—even well-formulated keto programs—don’t address habit change. Instead they promise instant transformation.  

And the dieters do transform, for a couple weeks. Then they yo-yo back to where they began. 

To succeed long-term, you need to break your bad eating habits and install good ones in their place. You need to become the kind of person who automatically eats healthy, no willpower required.  

But how?

How To Make A Nutritional Program Work

Most diets fail. Calories are restricted, food quality is ignored, bad habits aren’t uprooted, and the weight comes back. Frustrating. 

From years of research, writing, and tinkering in this area—including writing a popular book, Keto Intermittent Fasting—I’ve come up with a list of criteria for a successful nutritional program. 

 The program should:

  • Let you eat your fill, not limiting portions
  • Provide enough nutrients (like protein, vitamins, and minerals) to fuel essential needs
  • Restrict sugar, vegetable oils, and most processed foods
  • Include at least 12 hours of overnight fasting
  • Have plenty of clinical evidence behind it 
  • Focus on habit change, so the results stick 

As far as I know, only one of these programs exists…


A one-two punch for sustainable fat loss and better health.

Why Keto? Why Intermittent Fasting?

By now you’re probably wondering…

Why the keto diet? Why intermittent fasting?

The answer is simple: They work. 

Both regimens have been shown in human trials to promote weight loss, improve body composition, and enhance energy metabolism—among many other benefits.(3, 4, 5)

Keto and fasting are like best friends. They work together to get you burning fat and feeling better. 

Here’s the basic mechanism: By lowering blood sugar and insulin levels, keto fasting signals your body to enter the unique fat-burning state known as ketosis.(3) 

Put another way: Keto fasting gets you running on fat instead of carbs and sugar. 

This is right where you want to be, if you want to lose body fat and experience more stable energy.

I’ll cover all of this in Keto Fasting Foundation: whys, hows, specifics, and tips. 

In Keto Fasting Foundation, you’ll learn:

  • How to uproot bad eating habits and install good ones. (Hint: It’s not about willpower! If you could muscle through, you’d have done that already).
  • The fundamental reasons why most diets fail. (It’s not just you, and it’s not your fault).
  • How to stay accountable to your health goals without relying on willpower.
  • Why keto helps with weight loss—and why increased fat-burning is only half the equation.
  • How to choose a fasting regimen that works for you, including two criteria for making the decision.
  • Why combining the keto diet with intermittent fasting supercharges your metabolism to burn more fat. 
  • What benefits you might expect from keto fasting, including weight loss, better energy, less cravings, improved focus, healthier levels of inflammation, and more. 
  • How to track your progress on keto fasting, confirm you’re on the right path, and keep driving towards your health goals. 
  • Practical tips to succeed on keto fasting, including how to get enough electrolytes, avoid keto flu, track macros, test ketone levels, and more.
  • The best ways to exercise while keto fasting—and how to modify your routine.
  • Interesting science on how keto may improve the immune system. (Bonus module). 
  • And much more…

  • A bonus module on keto and the immune system. Now more than ever, it’s important to keep your immune system strong. I’ll cover some intriguing science (in both mice and humans) on the keto diet and immune health.  
  • Interactive daily worksheets to help you stay accountable to your health goals. When you write something down, you’re MUCH more likely to follow through. This is made easy with interactive worksheets to track sleep, energy levels, digestion, food intake (macros), and more. 
  • An “Eat Keto” cheat sheet to stick on the fridge. Take the guesswork out of what you can and can’t eat on keto. Don’t worry, it’s less restrictive than you think. Plus, carb cravings tend to be temporary as your metabolism adapts to burning fat.
