Changing the eating to such where you exclude, rice, potato etc..allows you to retrain your insuline levels as todays food allows you to create inflamatory responses which isnt good.

Todays advice in how to eat is wrong,
got a sister that lost 30 pounds in 3 months following this.
she got more energy, feels better.
Food creates responses in your body due to chemical reactions which enzymes and hormones trigger of good or bad sideeffects.
Most people just eat wrong and carbos has to be excluded as they are a later addition to our cost.
When one has created a better level of responses, one can eat some but should be kept to a minimum due to the inflamatory responses they create.
I eat like that, and I got more energy and feel better, and I eat 75% less food now than 2 years ago and feel better.
Not hungry as often, more energy, stable insuline levels and the effect are noticable what food I eat and carbs just dont work that well.
so in advice, dont listen to people as yourself who dont know.
