Want a shortcut for weight loss? Anyway, why do you want a shortcut?
What do you do when your best friend comes to your home after 2 years? Do you give her/him a glass of honey and lemon with water or do you make yummy parathas dipped in ghee? Got my point? When you know how to shower love on others, why not shower some on yourself too?
In short, honey and lemon with water does not help you lose fat. Honey and lemon will only help you stay hydrated. The fat loss will only occur if you are on a calorie deficit diet. In other words, if you are eating less than your burn.
