You want the healthy or the unhealthy way?

The best way i've come across (which I am doing myself) is having a Ketogenic Diet. Fats serves a purpose within our body and that is a store of energy, what use is the store if it's never used?

Our bodies are evolved to be able to store energy and use them in times of famine and hunger, our genetic forefather's do not get 3 meals a day if even 1 a day. They go for days without real food thanks to the fat stores in their bodies. Unlike today's society where we have easy-to-obtain calories. But sadly our bodies havent evolved to this change, it is still all about "keep keep keep keep all of it"

Ketogenic is in a way mimicking our ancestor's healthier lifestyle and work in away that our bodies are meant to.

Do you know that humans dont eat Carbohydrates as a form of energy until the Agricultural Revolution? when humans invented farming? We humans actually don't need Carbs to survive, Carbohydrates are only empty calories, calories that we don't really use that much in the modern desk sitting society.

Ketogenic Diet is a form of diet that you do not eat any types of carbohydrates,

Wheat
potatoes
breads and cakes
rice
sugar

All are a no-no in the ketogenic diet, all to be replaced with fatty meats and lots of vegetables.

Such a diet will force your body to drain it's glycogen stores and start burning down the fat., it's possible you dont even need heavy exercise to start seeing results.
