Carnitine is thinner, because it is an amino acid-like nutrient that provides more energy to the muscle causing it to expend the accumulated fat to perform its functions.
Its consumption inhibits the deposition of fat in the liver caused by alcohol and reduces the risk of heart disease by lowering the rate of triglycerides in the bloodstream. This nutrient can be consumed as a supplement found in pharmacies and naturopathies.
In this case, it should be consumed before physical activity and never at night, because being an energetic, can cause insomnia. Many are the benefits of carnitine in the body, but this should not be consumed by people who have a low BMI or have little muscle mass.
The food that most provides carnitine to the body is meat, especially mutton. Check out the L Carnitina leaflet.
