A ton of good info in here. I have been fortunate to never have an issue with being overweight, but both my wife and I are into bodybuilding (in fact she's prepping for a show), so nutrition and exercise are very key parts of our lives.
Yes, at its' core, calories burned > calories in = weight loss. However, it doesn't mean eat 2000 calories of potato chips and burn 3000 calories exercising. It's common sense. A good balance of proteins, fats and carbs. Yes, your body needs carbs...but not in massive quantity. You may not like greens...they're not my favorite either, but if you want to lose weight, you're going to have to try to incorporate some of that into your diet. You just will. There are plenty of foods I don't really like, but I eat because of my goals. Examples are greens, no-fat greek yogurt, albacore (tuna). I don't like them, but they're part of my regular nutrition. If you truly set yourself a steady nutrition plan...I hate the word "diet"...and are honest with yourself and stick to it, then even when trying to lose weight, you can allow yourself one cheat meal a week. I have mine every Friday, and let me tell you, I pig out for dinner. It gives me something to look forward too all week. And like others said, watch your liquid intake. I typically only drink water or the occasional diet and caffeine free soda (0 calories). I don't drink alcohol or sugared drinks. At the end of the day, you have to be honest with your own nutrition. If you cheat on your plan, others may not know, but your body will.
Muscle burns more calories than fat. So don't think 100% cardio at the gym is the way to go. It's not. Center around weight training and throw some cardio in to exercise your heart. Doesn't mean you have to lift hard to try to max out, but use weight training. The more muscle you build, the faster your weight loss will happen.
Really, IMHO, the hardest thing about all of this is just getting into a habit and routine. Change is hard. Totally transforming your nutrition intake (I'm guessing it's not very good right now) and exercise plan is not easy to do. Find your motivation...I'd say being a father should do the trick...and let it fuel you. Come up with a plan that is realistic and achievable, but make no mistake it will be hard work. Also, remember that there is no magic bullet. You didn't gain all the weight overnight, so don't expect to lose it overnight. Once you've made the changes part of your routine, it'll get much easier. My wife and I get up at 4am every day and are in the gym at 4:40am. It's just what we do. Yeah, I'm a bowl of jello by 9pm, but that's the lifestyle I chose because I'm committed to getting results. Eating those foods I'm not fond of is also just part of my normal day. I don't think much of it anymore...except that every day gets me one day closer to Friday.
In actuality, don't think of it as "weight loss", so much as it is reshaping your body. It's more about body fat % than the actual number on the scale. If you're 220lbs and 18% body fat, that's a heck of a lot better than being 200lbs and 33% body fat. Typically, yes, a fit person will weight less than someone very obese, but muscle is much denser and heavier than fat per square inch, so don't get too focused on the number on the scale. I weigh myself from time to time as a curiosity, but I'm much more interested when I do my body fat % testing.
Sorry, didn't mean to throw so much at you, but I'm pretty passionate about this stuff. Hope it helps.
