Caffeine and The Myth on Weight Loss (I)
Kitchen Section
In some slimming products, caffeine is attributed to the role of ‘fat burning’, but so far no scientific evidence to establish that the substance may facilitate weight loss.
As we approach the spring and summer, a larger number of products, whether oral consumption or topical use, including caffeine among its components. The rate at which allude, is that caffeine activates lipolysis, ie the removal of fat and, as this approach may be useful to accelerate the process of thinning.
Knowledge of the effects of caffeine on fat metabolism in humans is limited, and the results of studies that were conducted, are controversial. Various investigations show that administration of caffeine leads to increased plasma concentration of fatty acids, which action has been attributed the potential effect of caffeine as a substance stimulating lipolysis, ie the mobilization of fat the body, and therefore the consequent loss of fat and weight.
But this idea contrasts with the Conclusion No other reports carried out on animals have shown that while caffeine increases the conversion of fats into fatty acids during digestion and there is a greater concentration plasma free fatty acids, has not shown an increased oxidation of fatty acids, ie, there is a greater use of these substances by cells as energy substrate.
With the addition of caffeine in beverages, there are regulations requiring the warning of the presence of this substance after a certain amount. This is the European Directive 2002/67/EC, which requires manufacturers to clearly inform the presence of caffeine on the labels of beverages containing more than 150 milligrams per liter.
Also, the product must include the following warning: ‘High caffeine content’. This rule applies to some soft drinks and energy drinks that contain caffeine, but tea, coffee, or their derivatives, since it was felt that consumers should know that these foods are the main sources of caffeine.
