Why can some people eat so much and STILL manage to stay slim?

Because their metabolism burns calories faster — and Metabolism Booster Extreme helps you do the same:

Contributes to fat metabolism2 and normal metabolism1

Contributes to normal energy-yielding metabolism¹ and normal macronutrient metabolism⁶. Guarana is traditionally used to contribute to fat metabolism, which in turn helps weight control.

Controls appetite and cravings with Garcinia cambogia and Gymnema sylvestre

Garcinia cambogia reduces a sense of appetite and helps appetite control³. Gymnema sylvestre is also called the »sugar blocker« because it and decreases cravings for sweet.

Supports weight control and reduces fat storage

Garcinia cambogia contributes to the reduction of fat storage and helps in weight control.³

Suppresses fat formation (lipogenesis) with HCA

HCA is an acid, found in Garcinia cambogia that suppresses the lipogenesis – formation of fats – and their accumulating in the body²

Reduces tiredness and fatigue with magnesium

Metabolism Booster features magnesium, which contributes to the reduction of tiredness and fatigue¹. Guarana suppresses fatigue as well.

Why boosting metabolism beats just exercising for weight loss

Exercise is healthy and good for you, but the key to weight loss is boosting metabolism; meaning your body burns calories quickly, turning food into energy at a high rate.

  • A slow metabolism burns fewer calories; that’s why some people have difficulty losing weight by just cutting calories or working out.
  • A fast metabolism burns calories at a quicker rate, which explains why some people can eat a lot and not gain extra pounds.

 

The higher your metabolic rate, the more calories you burn 24/7, even while you are sitting at your desk working or watching TV.

Metabolism Booster targets the process that creates fat deposits

But metabolism is about more than just burning calories, it also involves how your body stores excess energy.

That’s why Metabolism Booster supresses the lipogenesis – formation of fats – and their accumulating in the body, food intake, and induces weight loss.³

Garcinia cambogia in this formula contains hydroxycitric acid (HCA) that helps slow down this process and:

  • Contributes to reduced fat storage
  • Reduces sense of appetite, which helps you eat less and helps  you lose weight with less effort
  • Supresses the lipogenesis – formation of fats – and their accumulation in the body
  • Contributes to weight management
  • Helps in weight control

 

With added bilberry, Gymnema sylvestre and other extracts – this formula is the ultimate choice for speeding up your weight loss results.

Why you should start Metabolism Booster today

  • You support normal energy-yielding metabolism¹
  • You contribute to appetite control and weight management³
  • You help reduce cravings for sweets⁴
  • You begin reducing fat storage and supporting weight control³
  • You activate normal macronutrient metabolism⁶

Starting Metabolism Booster LATER:

  • You delay support for energy metabolism
  • You postpone appetite and cravings control
  • You wait to activate fat storage suppression and weight management
  • You miss out on the metabolic benefits of 8 active ingredients working together
