If someone has an eating disorder, they need to also seek some type of counselling. Men can have eating disorders too, but women are more likely too than men, sadly.
Diets that combine too much fat with carbs is a fattening diet and that by itself will cause eating disorders because the only way for some people to get lean on a diet like that is to calorie-restrict and or over-exercise, but there will always be consequences to that because the body doesn't like being at a calorie deficit. No other species restricts their calories and we shouldn't either.
