The myth of warm water, honey & lemon for weight loss

Of the many myths that I have seen being propagated in India, the one that makes me curious is the one on the warm water, honey and lemon combination to reduce fat. I have seen this grow in my family even in childhood as one of my aunts used to religiously drink it each morning. I was too young to understand what she was trying to achieve, but I suspect she was try to lose weight.
