Orlistat
Amsa Fast is made from a single active ingredient called orlistat, which is said to be a gastric and pancreatic lipase inhibitor. When you inhibit these digestive enzymes, you are also inhibiting fat metabolism from the foods you eat in your diet (1).
Studies suggest that lipase inhibitors such as this can reduce the absorption of fat by as much as 30 to 40 percent. This means that orlistat would be able to significantly prevent fat absorption, fat storage, and weight gain if it works in the manner that it claims.
However, there is a lot more you need to know about orlistat before you take the Amsa Fast diet pills and expect to experience significant weight loss.
For starters, to make orlistat (Amsa Fast) work, you must also be following a low calorie diet and getting regular exercise, so it is not some miracle diet pill that will produce a massive reduction in your stored fat on its own.
Even then, if you are on an extremely low fat diet it will have little effect, as it prevents the absorption of fat, not calories. This means you need to make sure you have an extremely balanced, healthy diet for the supplement to work, not just a diet low in calories (2).
Then there is the fact that orlistat may not work, depending on how much weight loss you are trying to achieve, as it is only an effective weight loss supplement for people who are significantly overweight.
This means, while it can be used to treat obesity, it won't aid the weight loss process if you have minimal stored fats and are only seeking a small amount of weight loss (3).
Finally, there is the lengthy list of side effects that are linked to the Amsa Fast capsule (4). In addition to being a fat blocker, one of the biggest side effects of orlistat is that it can also block the absorption of fat soluble vitamins and beta carotene as well.
While this can be counteracted by taking an additional multivitamin supplement, it only adds to the already high cost of taking Amsa Fast and can cause other health issues if you don't realise it is happening.
Beyond this, orlistat can also cause more noticeable side effects, like high blood pressure, high cholesterol, gastrointestinal discomfort, abdominal pain, dry skin, poor energy levels, bowel issues, and a number of other long term complications, such as developing eating disorders.
