Dancing Love
Unfortunately there is indeed a double standard. Studies have shown repeatedly that for men, the most important factor in choosing a partner is looks, because they are programmed to spread their genes to women who will produce healthy offspring, and if a woman looks healthy and young she is more likely to give him healthy children. For women, a man is very attractive if shows that he has the resources and power to protect her and her future children. Physical appearance is of course highly rated as well, but, as you have noticed, often it is the more powerful/richer man who gets the beautiful woman.
Also the waist to hip ratio indicates the health and fertility of a woman: "WHR is considered to be factor in judging female attractiveness. Women with a 0.7 WHR (waist circumference that is 70% of the hip circumference) are often rated as more attractive by men, regardless of their culture, race, religion, ethnicity or any other subjective factors. Such diverse beauty "icons" as Marilyn Monroe, Twiggy, Sophia Loren, Kate Moss, and the Venus de Milo all have ratios around 0.7 despite having significantly different weights. Consequently, there is strong evidence to suggest that from an evolutionary perspective humans use subtle biological cues, such as WHR, to indicate mate potential and fertility."
A big waist (i.e. abdominal fat) indicates to the subconscious male visual perception that either the woman is already pregnant, or is close to menopause, so decreased fertility.
I strongly suggest you get the book "Supervixen" by Negrita Jayde, she talks about how important a woman's curves are, even if she is overweight she has the potential to improve her symmetry and become more attractive to men.
Of course, following the suggestions here on curezone to lose fat permanently is the best solution.
