Sorry, I was really just leading you on to see what you would say. The difference in weight loss between men and women is overblown. The only real difference when it comes to weight loss specifically is muscle mass and basal metabolic rates. That being said, if a woman sets her mind to it and actually buckles down, there isn't anything stopping her from losing weight just as fast as a man. We can talk about water retention, the affinity for a female body to retain fat, etc, but those are all things that with the proper diet can be mitigated and shouldn't ultimately affect true weight loss.
Generally what you find when people make these comparisons is that all things are not equal. An out of shape man still generally has more muscle mass than an out of shape woman. If you took a man and a woman with equal percentages of body fat, both out of shape, and put them on the same diet and exercise routine, where the caloric intake was equal for both people relative to caloric output, the difference in weight loss between the man and the woman would be almost negligible with water retention counting for most of it. While weight loss isn't my specific field of study, I have a BS in Biochem, with a PhD in Nutrition, so I do have some idea of what I am talking about.
Anyway, ultimately, all I was trying to point out was that it was a really odd way of expressing it. Why a woman would claim to know about a men's weight loss more than a man is somewhat confusing.
I don't claim to know more. I was stating an opinion from my perspective and from the perspective of many of my female friends based on personal experiences. For example, a couple I know who were both overweight by a comparative amount they both went through a weight loss regimen with a personal trainer and dietitian and were very good at keeping to the program. He quite simply lost the weight faster than she did though they both put in the same effort. It took her about 3 months longer to lose the same amount of weight as he did. Caloric output aside there are differences in females versus males by way of hormones which do affect metabolism. I'm not saying you don't know what you are talking about. I'm just saying there are other factors besides just calorie intake and output that can affect the rate of weight loss.
On a side note it's great that you have that degree. Since my mom died I have been trying to figure out what to do with myself. I put my schooling on hold to care for her for the past 5 years...I'm actually looking at pursuing a degree in Exercise and Sport Science with an emphasis on Athletic training and nutrition. I would love to pick your brain some time.
