To lose weight do you need to take a look at what you eat, how much you eat and how often you eat. 70% is diet and 30% is exercise when losing fat.
A good way to keep track and get an understanding is by writing everything down, what you ate, how much, if you did any exercise, what kind of exercise, if you were sitting on the sofa all day or were you moving around and so on. You can also write down your weight and measurements to see if it change up or down depending on what you did every week.
It is easier to fight the enemy if you know what it is.
What I do to keep my weight:
I usually do a check after my meal on a scale between 1 and 10 how I feel, 1 is starved, 5 is neither hungry or full, 10 is so full your stomach hurts. I always aim for 6 or 7, above that and I ate too much. No sugar like candy, soda, restaurant meals or any other stuff with added sugar and I only eat three times a day. I only drink or eat out when I am with friends or coworkers.
Our bodies adapt so you should surprise it now and then to get ride of the fat. Experiment and keep track on what you do and your results so that you can actually see what works best for you, we are all different after all, and losing or keeping your weight is all about will power and habits.
you need to find a good balance otherwise you may never stick to the new routines.
