Maintaining healthy weight in the modern world is not an easy task…

Busy schedules often lead to poor dietary choices, combined with stress, lack of quality sleep and sedentary lifestyle, your metabolism slows down and you start gaining weight – even cutting down your calorie intake. It is a viscious cycle so many people struggle with today.

 

If you are experiencing:

  • Difficulty loosing weight: no matter how much you cut down your calorie intake
  • Feeling tired frequently: even though you have enough sleep and rest
  • Unhealthy food cravings: especially sugary food, because your body has trouble processing energy in the normal way
  • Digestion problems: because your body is unable to properly break down the food

 

Reduce calorie absorption and speed up your metabolism to reach your goal weight FASTER than ever!

With Metabolism Booster Extreme and OK!FatBurn

Premium natural ingredients with proven effects

Magnesium

Magnesium

Magnesium plays a key role in maintaining the normal functioning of the nervous system and muscles and supports energy metabolism and electrolyte balance. With magnesium citrate, the form that allows the best absorption and bioavailability, you can replace lost magnesium and avoid deficiencies that can manifest as unpleasant fatigue, lack of energy and muscle dysfunction, especially as frequent muscle cramps.

Guarana and Garcinia Cambogia

Guarana and Garcinia Cambogia

Guarana provides a sustained energy boost and stimulates fat metabolism, contributing to weightloss. Garcinia cambogia (Garcinia gummi-gutta) contains hydroxycitric acid (HCA), a natural compound that inhibits the enzyme lipase, which is responsible for fat breakdown in the body. This helps in preventing fat accumulation and weight loss in the body.

ID-alG™

ID-alG™

ID-alG™ is an extract of the brown seaweed Ascophyllum nodosum, which is rich in long-chain polyphenols called phlorotannins. They help to inhibit the action of the two main digestive enzymes, lipase and amylase, and block up to 77%* of carbohydrate digestion and 63%* of fat digestion.

Gymnema sylvestre extract

Gymnema sylvestre extract

Gymnema sylvestre (Gymnema sylvestre) is a plant used in Ayurveda, a form of ancient holistic medicine practised in India. The Hindu term for it is gurmar, roughly translated as 'sugar destroyer'. This is because gymnema leaves contain a compound called gymnemic acid, which selectively inhibits sweet tastes, resulting in a reduced desire for sweet.

Kelp

Kelp

Kelp (Ascophyllum nodosum) is a large seagrass that grows in nutrient-rich underwater habitats in shallow oceans. It is a source of iodine, which plays a role in the production of thyroid hormones and the normal functioning of the thyroid gland. Iodine also plays a role in cognitive function and contributes to the functioning of the nervous system.

Zinc

Zinc

Zinc contributes to normal immune function, contributes to normal DNA synthesis and cell division, helps protect cells from oxidative damage, helps maintain normal bones and contributes to normal cognitive function.

By week four I could see a noticeable decrease in my appetite, and my mood has improved significantly. It's amazing how much of a difference it makes when your body starts burning fat more efficiently.

After years of trying various diets and exercise routines with little success, I was feeling frustrated and defeated by my slow metabolism. After using these two, I finally shed some pounds, but I also feel more energized and motivated to keep pushing forward in the gym.

2 EASY STEPS FOR MAXIMUM WEIGHTLOSS RESULTS

Metabolism Booster Extreme + OK!FatBurn

STEP ONE:

Reduce calorie absorption

ID-alG ™ blocks up to 77% of carbohydrate and 63% of fat digestion enzymes

That means your body won’t absorb all the calories from your food, helping you loose weight even without changing your habits.

 

STEP TWO:

Boost your metabolism

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, helping you burn more calories 24/7.

Metabolism Booster Extreme and OK!FatBurn

HOLISTIC SOLUTION that addresses the 2 stages of food processing in the body – digestion and metabolism

Metabolism Booster Extreme + OK!FatBurn

8-in-1 formula with ProGarcinia™ supresses lipogenesis –  the process of storing excess energy as fat

Garcinia contains hydroxycitric acid (HCA), a natural compound with a high proportion of hydroxycitric acid that reduces fat storage in the body. With added bilberry, gymnema sylvestre, L-carnitine, guarana, magnesium, zinc and kelp – this formula is the ultimate choice for speeding up your weight loss results!

 

OK! FatBurn with triple action promotes weight and fat loss

ID-alG™ is a patented formula of brown seaweed extract that inhibits the activity of two main digestive enzymes, lipase and amylase. Additional power from L-carnitine and L-tyrosine. Vitamin C acts as an antioxidant, protecting cells from oxidative stress.

Together they:

  • Contribute to reduce the storage of excess energy as fat in the body
  • Reduce sense of appetite helping you loose weight with less effort
  • Supress the lipogenesis and their accumulation in the body
  • Reduce calorie absorption from fat and carbohydrates
  • Reduce food intake reducing cravings
  • Induce weight loss

This is the ultimate choice for speeding up your weight loss results!
