It has long been asserted that caloric restriction is the only effective method for reducing body fat, yet few people have success losing and keeping off weight with intermittent fasting diets, which work differently. In his WSJ Bestselling book, Weightlifting is a Waste of Time – So is Cardio, scientist, inventor, and author Dr. John Jaquish examines the fitness industry’s long-held myths and misconceptions about calorie restriction and outlines a clinically proven protocol for fasting that will reduce body fat and build muscle without ever having to be hungry.

“When the people in the gym look the same as the people in the pizza joint, there’s something not right about the gym fitness path. I have taken a different approach to this issue doing a very deep dive into the science of human physiology to find the answers,” said Dr. Jaquish.

“For anyone researching fasting, it is important to know how fasting is being defined. I am talking about ‘intermittent fasting’ also called ‘time-restricted eating’. This is when you fast for a certain amount of time a day and eat during a certain time of day. As an example, you fast for 20 hours and then eat during the other 4 hours of the day. While if you consumed the total calories for the day and instead had those calories spread throughout the day, your results would be worse,” said Dr. Jaquish.

In his book, Dr. Jaquish details the benefits of intermittent fasting;


  • No metabolic adaptation, meaning with calorie restriction, your body attempts to reset how many calories you need, therefore you can be suffering in a diet, all while your body has changed so that the deficit no longer works and you are putting on body fat anyway.
  • It promotes autophagy which is the body’s way of cleaning out damaged cells in order to regenerate newer healthier cells.
  • It can completely regenerate the cells of the immune system.

·- It produces more growth hormones that can protect from loss of muscle mass.

  • Most importantly, it doesn’t allow you to be hungry, which after all is the reason that many other diet approaches seem to fail for the vast majority of people.

Dr. Jaquish also describes what happens in the body during fasting, stipulating that the number of hours varies from person to person and these numbers are an average.

  • In the context of health benefits, “fasting” starts after twelve hours without consuming any calories. Around twelve hours after last consuming food, the body “flips a switch” and beings to break fatty acids down into ketone bodies which will become the new blood-borne energy replacing the glucose that the body is running out of.
  • At the 18-hour mark, rapid fat loss begins.
  • At the forty-eight-hour mark, growth hormones levels peak, on average, increasing to five times one’s baseline levels.
  • At fifty hours, insulin, which has been trending downward since the onset of fasting, typically reaches its minimum level.
  • At the seventy-two-hour mark, the body has been triggered to recycle and replace all of its T-cells (part of the immune system), effectively regenerating a substantial part of the immune system and reversing immunosuppression (a reduced ability to fight infections and other diseases).

“Research shows fasting is one of the healthiest things you can do to your body. Multiple studies have demonstrated that fasting can be undertaken while preserving muscle and losing fat and that fasting can lead to accelerated muscle growth after the fasting period. And there is a right way to fast to achieve these results,” said Dr. Jaquish.

The book is packed with research, studies, and details of the better way to have a strong lean body and good health.
