Is it more common for men or women to have weight fluctuations?

Women: Women must face pregnancy, menopause, birth-control, pressure to lose weight and thus frustrating diets which themselves can lead to weight gain due to metabolism shifts that result in fat storage, as well as many other factors. Men tend to have more abdominal weight gain. Healthy lifestyle with healthy food choices, fiber, sleep, exercise, and emotional calmness are recommended for stability.
