Is there any nutrition plan which is suitable for all kind of people?

Apparently, I'm weight of 74kg/176cm and trying to get rid of the fats if possible wanted to slim down to 70kg, with less fats in my body. But I guess I have some hard time on changing my nutrition.

Now hitting on cardios doing HIIT 20mins or sometimes the normal way for 45mins at jogging rate and rest for a while.

If not mistaken my fats on belly is 15%+- but not over 18%. Other parts are lesser than 3%

Daily nutrition :

- Morning on school days McDonalds breakfast since it's close to my college.
- Lunch after 2hours of Morning, Noodles/Rice
- Dinner rice(small portion) with some side dishes

(Going on)
Skip breakfast go to brunch, depends sometimes take breads sometime eat rice.
Tea time, bread/some oat milo drinks.
Dinner small portion rice with some side dishes
Sometimes I do take supper, but light ones.
I know my nutrition sucks to the max. That's why I'm here right now.

And I were wondering is it worth to look for a personal trainer? Cause I wanted to build a better body instead of having a lean looking, but a atlethic body.
