How is it unhelpful to be told what you need to do?
Are you saying you need more specifics?
If you want to improve your financial position, either earn more money (get a side job, take a higher paying job with more responsibility), or spend less money (buy beans and rice in bulk, prepare your own meals, sell your luxury car to get rid of the payments and drive a paid-for beater, take public transit and read a book on your commute instead of driving a car).
Similarly, to lose unhealthy weight, either reduce calories in (stop drinking sweet sodas and eating candy bars, order 500-800 calorie items from appetizer menus instead of 2000 calorie entrees) or increase calories out (exercise, take the stairs instead of the elevator, walk instead of ride, lift weights to improve resting calorie burning.)
But it's hard to come up with specifics that apply to everyone, since everyone is different. That's why we just say the general rule, instead of assuming people have an expensive car to sell or go through a 2 liter of Coke a day.
