Actually there few categories but I will mention few:

• women with most amazing genes, it does not matter What They eat or drink and skinny They are forever
• Those women forever on diet and They never loose anything "not sure if the diet is about eating They are on or talking about being on diet". 
• women who set goal of loosing And They Actually achieve the goal
• Those who try every pill on the market or injections to lose weight
• lately people choose to go for tummy tuck - "I  say shoulderstand amazing results but I am scared to go under the knife to achieve the skinny trim figure "
• Those who do not eat in a normal table setting but rather take Their doggy bag whichwill be the first thing They Do When They get home - eat it all and still go to the fridge for more. Somehow people ask why Themselves thesis proving people wrong big hypothesis: because women will never eat with you 
• Those women who just do not care, They Are comfortable With Their sizes it does not matter If They weigh 180kg
• ..... There are many many more other dieters With Their own diet pattern
