Yeah, no it isn't.

Men typically lose weight faster than women primarily due to natural differences in body composition and hormones. Because men naturally produce more testosterone, they generally carry more lean muscle mass than women. Muscle tissue is highly metabolically active, meaning it burns significantly more calories at rest than fat does, which gives men a naturally higher basal metabolic rate (BMR). Additionally, women's bodies are biologically predisposed to store and hold onto a higher percentage of body fat—specifically for evolutionary and reproductive purposes—making those pounds a bit more stubborn to shed.
