The Obesity Code Review - 10 Things You Need to Know

Because losing weight seems to be more challenging for some people than it is for others, there are various diet programs out on the market specifically developed to target the loss of stubborn fat. One example of a diet program that advertises that it can help virtually anyone lose weight is called The Obesity Code.

To find out more about this diet book, we looked into its ingredients, potential side effects, and relevant research. We also looked into its user reviews and author. Finally, we condensed all this information to give you the bottom line on The Obesity Code.

The Obesity Code can be purchased through their Official Site.

What is The Obesity Code?

The Obesity Code, authored by Dr. Jason Fung, MD, discusses a weight loss strategy tailored for individuals grappling with weight issues, despite diligently following conventional diet and exercise routines.

Dr. Fung challenges the prevalent notion that obesity hinges solely on calorie intake, fat grams, or physical activity. Instead, he posits that hormones, particularly insulin, play a pivotal role. According to his argument, elevated insulin levels are the culprits behind obesity, prompting him to advocate for a dietary approach centered around low-carb intake and intermittent fasting.

Within the book, Dr. Fung proposes the existence of an individualized fat-burning code within each person. He claims that this code can be deciphered to achieve efficient weight loss. Furthermore, he asserts that this code is malleable and can be reset through his recommended intermittent fasting regimen.

It’s crucial to note that these assertions are the claims made by the author and are not universally accepted in the scientific community. The book offers a perspective that challenges conventional weight loss wisdom, emphasizing the impact of hormonal factors in obesity.

What are the proven effects of intermittent fasting?

• Annual Review of Nutrition: Research into intermittent fasting is trying to prove efficacy in health, at this point. “Several lines of evidence also support the hypothesis that eating patterns that reduce or eliminate nighttime eating and prolong nightly fasting intervals may result in sustained improvements in human health.”
• Ageing Research Reviews: Various forms of fasting and time-restricted feeding “… in normal and overweight human subjects have demonstrated efficacy for weight loss and improvements in multiple health indicators.”
• CFP MFP: This study found that intermittent fasting could help with the treatment of obesity under supervision.

The Obesity Code Diet Rules

To follow The Obesity Code diet properly, the author claims its users have to start eating like their ancestors. It’s no easy task, though.

First, all snacks are eliminated, and food is only for consummation during specific times of the day.

During the fasting periods, only liquids, such as coffee, tea, water, and broth, are allowed. Those following the program are encouraged to drink as much of these as they want. As long as they don’t add sugar or any form of milk to them for flavoring.

The Obesity Code and Exercise

The Obesity Code encourages exercise during your fasting time. It is because early humans had to keep traveling across far distances each day to survive, even if they were hungry and tired.

However, exercising after not eating for several days in a row is difficult because the body is starved of energy. Plus, if a person pushes themselves too hard with such little energy, they could become hurt a lot easier.

The Obesity Code Food List

Unfortunately, The Obesity Code doesn’t give a lot of information about what food a person should eat during the intermittent-fasting schedule. It focuses more on the consumption of clear liquids and the avoidance of food altogether.

However, it does encourage regular “free days” where a person eats whatever they want without considering the nutritional or caloric nature of them. This could make it more challenging to follow a pattern of healthy eating.

The Obesity Code Book Claims

The Obesity Code is just one version of an intermittent-fasting program. There have been many of them created, but their concepts are all based on the same health principles.

The author of The Obesity Code says that the current way that people eat several times a day exhausts the pancreas from having to release insulin to lower the blood sugar spikes continuously.

Dr. Fung also claims that a person’s body has a “secret code” built into their body related to their genetics. By forcing the body to go without food through the use of an intermittent-fasting program, they can change this code, allowing their body to start burning fat at a higher rate than it normally would.

The Obesity Code Program Benefits

The Obesity Code claims that a person can have the following health benefits while following their diet plan:

Increased Testosterone

When someone stops eating so much food, they develop a lower level of body fat. Fat contributes to the production of estrogen, which is why those who are severely obese may have a hormone imbalance.

By lowering the amount of fat in the body, there is less estrogen overload. This may have a beneficial impact on muscle mass, energy, sex drive, and self-confidence in both men and women.

Weight Loss

The significant drop in the number of calories that are consumed daily causes weight loss. However, the weight that is lost varies from person to person.

Some people claim to be able to shed 20 pounds or more in a month while intermittent fasting. However, we could not find users who experienced such drastic weight-loss after trying The Obesity Code diet plan.

Improved Energy Levels

The Cleveland Clinic says that when the body stops expecting food regularly, it may adapt to use the fat that a person already has and the sugar that it receives when someone does eat more efficiently.

This could help improve a person’s energy throughout the day.

Is The Obesity Code Diet Safe?

If the methods used in The Obesity Code are applied for a short period, as a method of healing the pancreas and boosting the metabolism, it may be safe to try. However, most health experts say that it isn’t an excellent program to use for more than a month.

Those who are pregnant or nursing should never attempt intermittent fasting. Parents shouldn’t have their small children use the program either, even if they are overweight.

People with blood sugar issues or health conditions have to be especially careful if they try The Obesity Code too since it could make their blood sugar level too low.

Is The Obesity Code Expensive?

The book costs $20 online. Users don’t have to purchase any prepackaged meals, snacks, or drinks either.

The amount of food that a person eats is severely reduced, which means that they have to buy fewer groceries than usual.

Overall, it is one of the least expensive diets that someone could try.

What Users Are Saying

The Bottom Line on The Obesity Code

At this point, you’re probably wondering if this book is worth buying. Unfortunately, we have some concerns about their diet. First, their claims don’t seem to be backed by research. Additionally, intermittent fasting can be a very difficult dieting method to follow.

Losing weight shouldn’t have to be so hard. If you’re looking for effective diet support, you should choose a program with clinically-researched methods.
