The Lemon Water Myth
Drinking lemon water can help you burn fat and lose weight.
The hype over lemon water likely stems from a 2008 Japanese
study that linked lemons' polyphenols - micronutrients with
antioxidant properties - to less weight gain and improved fat
metabolism in mice that were fed a high fat diet. The study team
claimed that the lemon polyphenols may stimulate liver enzymes
that help block the absorption of dietary fats.
The study was done on mice. No rigorous studies have been done
showing that lemon water can promote weight loss in humans.
Mice in the study were eating a diet loaded with lemon rind, the site
of most of the polyphenols in lemons. Most people who drink lemon
water don't consume the rinds but just consume the juice.
The Up Side:
Lemon juice is full of Vitamin C and some studies have linked low
vitamin C status to obesity. More importantly, however, is if lemon
gets you to drink more water, that can go a long way towards
weight management as thirst is often mistaken for hunger.
