"If Trim inhibits fat absorption, will it also inhibit the absorption of necessary healthy fats?"
CLA works to prevent fat deposition by modulating the enzymes that control fat deposition. This will not change the absorption of fat-soluble vitamins, and generally speaking, any fats not absorbed by the body are excreted through feces. In addition, several clinical trials found no impact on the blood lipid levels of volunteers.
Fat will be absorbed into the body either way and once in the body, the CLA works to reduce body fat by preventing fat accumulation in fat cells. Fat normally enters the fat cell through a “door” that is controlled by an enzyme, the “key”. By acting on this enzyme, or “key”, CLA keeps the “door” locked. When the “door” is locked, fat cannot enter the cells thereby not allowing the amount of fat to increase in the cells. The less fat that is present in the cells, the smaller and less mature they become, this helps to reduce the level of fat in the body. The increased breakdown of fat helps to fuel and preserve muscle mass, which in turn increases lean muscle mass.
