I'm going to resist the urge to tell you to go **** yourself and learn how to use google, but I'm in a good mood so I'll try to help you out instead.
First suggestion really is to get your *** on google and stop asking stupid questions that can be answered in less than 15 seconds by typing them into a search bar.
Once you take care of that, get down to business. Find out what constitutes healthy food (I'll give you a hint: look for food in the most natural state you can possibly find it in and you'll generally be in pretty good shape). Then get out there and start busting your ***, it's that simple. Try to aim for a macro nutrient (carbohydrates, protein, fat) ratio of 40/40/20 (in that respective order) and make changes as necessary every two weeks or so. Eat 5-6 small meals per day rather than 3 big ones, and try to make the macro nutrient ratio 40/40/20 in each individual meal as well. Make sure that every meal contains about 1/6th of your target caloric intake (which you should figure out if you want to actually try to get healthier) for the day, assuming that you eat 6 meals per day.
As for exercise, don't try to bull**** yourself into thinking that what you're doing is actually helping. It's not...not even in the least. You need to actually bust your ***, and you're not going to like it, but if you want to get results you need to put in the effort. If you don't like running, then don't run...there are a thousand other intensive cardio activities you could do instead, many of which tend to be a lot nicer to your knees than running is. And don't blow off weight lifting - it won't "burn fat" in quite the same way that cardio does (except for HIIT, which is something you need to research), but with enough of it you will eventually raise your resting metabolic rate. You need to research that too, by the way.
Above all - set a schedule and stick to it, don't make excuses, do what you know you need to do, and you're riding the gravy train with biscuit wheels.
