My personal story:
4 years ago I was 5’11" and about 240 lbs (similar to you, a bit fatter even).
My diet primarily consisted of trying to understand a few things and applying them to my life.
-The relationship between calories, metabolism, and weight gain. You want your body to feel like it’s getting just about what it needs every day so it doesn’t kick into super-slow starvation metabolism mode.
-The body needs roughly 1 pound of fat to store 3,500 calories.
-I’d bet your natural metabolism probably burns about 2,400 calories in a day when it isn’t trying to conserve. If you ate five 400 calorie meals/snacks a day you’d probably lose about a pound a week even without exercise.
-Drop stupid ideas about food. “Fatty” foods don’t make you fat - your body breaks the fat into calories similarly to anything else. Not paying attention to calorie intake makes you fat (and it’s easy to not realize that what many restaurants sell as a one-sitting meal contains more calories than your body needs for the entire day!).
Snacking is not the problem. Snacking can be part of the solution even - you could eat three 500 calorie meals a day (breakfast, lunch, and dinner) and have three 200 calorie snacks in between. Also, drink copious amounts of water. It not only is good for you, it will make you fill “fuller.” You need to understand the caloric content of food though. That’s pretty much key.
A lot of diets that require eating specific types of foods actually work on this principle - a vegetarian diet isn’t “magic” because you’re cutting out those evil fats - non-starchy vegetables simply suck as an energy storage medium so people just aren’t getting many calories out of eating even huge salads. Also, there’s a limit to how many calories you can consume snacking on vegetables for the same reason - you will physically be full before you overeat from a caloric perspective.
Anyways, I’m 180 lbs now and have been for 3 years. Since I’m not actively trying to lose more weight, I generally consume 2,000-3,000 calories a day, spread out over my waking hours to keep the metabolism up. Occasional gorging isn’t even a huge issue - with a healthy metabolism your body might not try to extract and store every last calorie from that thanksgiving feast where you downed 7,000 potential calories in one sitting.
