General Diet Plans and Questions - Calorie counting and percentages

I have tried WW several times and failed. I am going to try to count calories and I'm going to stay between 1500-1800 calories per day. What percentage of fat should I be eating. I have heard that 20 to 30 grams per day but I have also heard 25-30% of your calories.

Can someone offer me some sound advice or perhaps point me to a website that will provide me with accurate information?

Hi,

My personal trainer and nutritionist has me stagger my percentages of carbs, protein and fats.

For instance:

60/30/10;

40/40/20;

55/40/15.
