Fat: The Weight Loss Secret

Fat: The Weight Loss Secret aims to debunk common beliefs about fat in relation to dieting.


The author, K.D. Joseph, claims that humans are genetically designed to consume a high-fat diet. He asserts that:

  1. We need to eat large amounts of fat in order to maintain good health.
  2. Eating foods high in fat helps you achieve a lean and muscular physique.

Joseph promises dieters,

“You will lose at least 5 pounds in the next 10 days by following this advice or I will give you $10.”

Fat: The Weight Loss Secret Basics

Fat: The Weight Loss Secret says that the goal of this book is to show you how easy it is to start eating a more healthful diet. It can also help you lose weight, if that is something you seriously want to do.

Fundamentally K.D. Joseph advocates a low-carbohydrate, Ketogenic diet, similar to that promoted by followers of the Paleo Lifestyle. He says the key to becoming healthier is to imitate the diet of our ancestors, which he believes consisted of lots of fats and not many carbohydrates.

Eat Like Your Ancestors

Fat: The Weight Loss Secret asserts that plants and fruits were not readily available until the advent of agriculture and farming. So humans had no choice but to subsist on a diet made primarily of fatty animal meat.

He claims that for the best results you need to limit your intake of carbs to 100 grams (or less) per day.

Joseph says when you follow this diet you can eat as much food as you want and still lose weight for good. You will never feel hungry or deprived, yet you will continue to release excess pounds week after week.

Readers are introduced to 14 different “power foods” that have unusually fast fat-burning effects.

Essentially Another Low Carb Diet

Fat: The Weight Loss Secret advocates a weight loss plan based on limiting carbohydrates while allowing for a high intake of dietary fat. Primarily it is based on the opinions of the author who does not provide any scientific research to support his claims.

Essentially it promotes a Paleo diet where carbohydrate intake is limited to no more than 100 grams per day. This approach is often successful for short-term weight loss. However research suggests that this way of eating is generally less effective for long-term weight management.
