The company Intechra Health is a US company that manufactures all its health supplements in an FDA-registered facility that follows all the GMP guidelines. This says a lot about the standard maintained, its quality, safety, and effectiveness.

The name “Fenfast 375” has an underlying reference to Phentermine that was considered one of the best diet pills in the world for weight loss. While it worked amazingly well, the side effects were detrimental. This was why it was removed from the shelves. It is currently made available only via prescription and only for those who are suffering from extreme obese conditions.

So how does Fenfast 375 really work?

Fenfast 375 tablets are synergistically designed to kickstart the body’s natural effort to lose weight. It mainly focuses on the three areas that will help you reduce weight naturally.

  • Control the appetite
  • Burn excess fat and
  • Increase the metabolism level

The ingredients of Fenfast 375 diet pills are programmed in such a way to control unwanted hunger pangs. They also promote a “thermogenesis” effect on the body. Thermogenesis means to produce heat (within the body) thus burning away chubby fat.

Stating the obvious, just taking the supplements isn’t enough to lose more than a few pounds. You need to combine it with a healthy dietary lifestyle plus workout routine.

The manufacturer doesn’t claim what makes Fenfast 375 curb the hunger. For instance, a person who has a high metabolic level will obviously have a bigger appetite as the body will process the food much faster than others.

Lastly, Fenfast 375 claims that you will note an increase in the metabolic rate and you will have your energy levels high all through the day. This might be able to help you lose around 15-25 lbs a month.
