L-Carnitine makes fasting easier and more effective

Fasting for a couple of days every so often is very healthy, but a lot of people find this really difficult. They feel hungry and tired. Doctors at the Sun Yat-Sen University teaching hospital in China discovered that supplementation with L-carnitine can help these problems. What's more L-carnitine increases the amount of body fat you can lose through fasting.

L-Carnitine
Study
The Chinese did an experiment on two groups each consisting of 15 obese adults. One group was given injections twice daily containing 2 grams L-carnitine for 7 days; the other group was given injections containing no active ingredients.

The Chinese chose to give injections because the body does not absorb orally administered L-carnitine easily. How to get round this problem you can read here.

All subjects started to fast on day 3 of the experiment. They ate 200 kilocalories per day, for example vegetable soup which they ate for breakfast and lunch. During the fasting period the subjects also walked for a couple of hours every day.

Results
The L-carnitine injections speeded up the weight loss. The placebo group lost 3.2 kg, the L-carnitine group lost 4.6 kg.

Conclusion
"Interestingly, together with fatigue improvement, weight loss and anorexia was significantly promoted with intravenous L-carnitine administration during modified fasting therapy in our study", the researchers write. "In addition, a reduction in waist circumference was also seen in the L-carnitine group. Based on these results, it was inferred that L-carnitine was able to promote lipolysis and contribute to preservation of lean body mass during fasting."
