Standard diets (Keto, Paleo, Atkins, Karatay, Vegan, Vegetarian, Mediterranean and others) will not be effective in everybody as ONE SIZE DOES NOT FIT ALL.
The standart diet proposed to patients will have less than 10 % of efficacy as variables in one person differs from another person in many aspects
Diet must be personalized. Energy consumption, daily calorie intake, physical activity, age, weight, height and most important of all metabolic types differ among individuals.
Moreover, gender effects body fat hormones and metabolism and thus must be an important factor when designing diet.
Standard commercialized diet most probably will not fit to you.
Diseases (cancer, hypertension, diabetes, heart and romatological diseases) as well as drugs and chemotherapy, radiotherapy and surgery used may interfere with diet so special attention is mandatory when designing diets.
Therefore do not use every diet especially when it is not tailer made for your body.
