This diet is marketed and promoted by a company called bulletproof 360, Inc.

The bulletproof diet was created by Dave Asprey an entrepreneur turned biohacker in 2014. A biohacker is a person who employs science and technology to his or her lifestyle, to make his or her body function more efficiently.

How does the bulletproof diet work?

The bulletproof diet is an upgrade or modified form of keto diet where the aim is to get 75% of the calories from fats, 20% from proteins and 5% from carbohydrates.

The foundation of the diet is starting each day of the week with bulletproof coffee. This is believed to suppress hunger while boosting energy and mental clarity.

It involves eating foods high in fats and low in carbohydrates for 5-6 days a week and having a refeed of carbohydrates for 1-2 days. The purpose of the refeed is to avoid the side effects of long term keto diet such as constipation. This puts the body in ketosis state where the body burns fats for energy instead of carbohydrates.

It also involves intermittent fasting whereby you abstain from food for specific periods.


Does the bulletproof diet really lose weight?

Like many other similar things, this bulletproof diet review may not be taken as gospel truth but should be a guideline to help you make smarter choices on whether the bulletproof diet is good for you or not.

As a matter of fact, the best way to enhance weight loss is to follow a reduced-calorie intake for a sustained period.  There is no single based diet for weight loss. Research shows that high fat intake and low carbohydrate intake like in the case of a keto diet can help you lose weight faster compared to other diets.

The impact of the bulletproof diet, therefore, depends on the volume of the calories you eat and how long you can sustain that number. Keto diets fill you and make you eat less which eventually helps you lose some weight faster.

However, as we all know, you cannot reduce weight entirely depending on food intake. Reducing calorie intake is very important for one seeking to lose weight.

Another concern is that for the bulletproof diet to work effectively, the diet has to be followed for a long period of time. This is a big problem because people may find it hard to follow in a sustainable manner.

Body exercise is the foundation for your resilience and energy levels.
