You are asking two questions.
The first asks about women’s health. The second mentions fat loss. Fat loss in certain circumstances is part of a woman’s health, though not always, and it is never a fact in isolation of many other circumstances.
As Harris suggests there are many factors at play. And a part of the role of anyone who works in fitness is to address the unique needs of each person. If you determine that fat loss is part of what needs to be addressed it will best be addressed not by one ‘best’ method, but by using a number of tools in the box together. Cardiovascular exercise, weight bearing exercise, meditation, nutritional counseling, yoga, social engagement and support….. many things have a role.
