Ask the Dietitian: Does Lemon Juice Speed Weight Loss? by Toby Amidor in Ask the Experts, Diets & Weight Loss, March 1, 2013
Q: Does drinking lemon just help with or speed up weight loss?
A: If you’re looking to lose weight or speed up your efforts, it’s all about eating right and regular physical activity. Sipping on lemon juice or adding lemon juice to warm water isn’t the magic solution.
There are many myths surrounding lemon juice that just don’t have the scientific evidence to back them up. I’ve heard that lemon juice improves digestion and regulates sugar absorption — both don’t have enough scientific evidence to make strong claims. One of my favorite myths is squeezing lemon juice on chicken in order to melt the fat away– unfortunately, that’s an unfounded claim. Acidic ingredients like lemon juice, however, are used in marinades to help tenderize meat and poultry by breaking down collagen, a fibrous compound that aids in the formation of connective tissue.
A second myth that’s often discussed around the water cooler is that when lemon juice is mixed with cold or lukewarm water it’ll dissolve fat in your body. Again, this doesn’t happen metabolically, though drinking more water (cold or lukewarm) will help you stay hydrated.
