What is the difference between weight loss and fat loss? Which of the two is recommended more than the other?

I was under the impression that fat loss leads to weight loss or vice versa but it seems both are different. Can anyone explain the difference?? and I want to get any advise/tips for fat/weight loss… thank you

what little things make a difference in a fat loss diet?

For example. Drinking water and not soda. Eating your last carbs of the day at tea time. Cutting out fast food. Do you know any other little things like that that can make a difference when you diet?
