Jerome,
I am going to give you some real good advice, but I must say that I know that its much easier to say than follow. But if you are willing to listen, I'll bet that pretty much most people will agree with my assessment of your situation. With that said, no matter what, I wish you good luck and I hope you keep training and get yourself fit.
Now based on your age and body size and weight situation I have a few good steps for you so that you can get a handle and correct your situation.
The first thing that I want to address is the whole diet and exercise thing. First of all, its great to think that you will go balls out and change it all the bad habits and do and eat all the right things so that all so your workouts go perfectly and all your meals go incredibly well.
The reality is that this is a myth, a lie. Its impossible and all those people who say that they do this are either lying or have substituted exercise or eating diligence for some other bad habits they had, just like a recovering alcholic does with coffee or like an ex smoker becomes a gum chewer. Now for all those reading this that have accomplished the impossible, good for you. CONGRATULATIONS, you have really done the impossible, but this is not for you or about you (although we would love to hear about your success and tricks you discovered along the way).
So anyways, here is what I think you should try. First of all, unless you are about 7'2" I think that you are way too heavy for your frame. Your goal is a realistic 150lbs and I think that you can accomplish this in about 16 months.
But how? > First of all, although the walking is great, most people dont tell you how freaking boring it is. The other thing that they dont tell you is that its not really a walk that you are after. What you are really supposed to do is get your heart-rate up to a fat burning level. (check the charts) In laymans terms, that means that you have to walk fast enough to be sweating. The way to check this is that after 6 minutes, if you dont have sweat beading down your forhead, you are going too slow. (If you are breathing really really heavily then you are going to fast. ) Realistically you should try to do this for about 1 hour a day. And YES you can break it up. But this exercise (walking) has to be focused and uninterrupted. Any stopping and going will not help you achieve the results you want and it will discourage the heck out of you.
Since you are young I am going to give you some simple tips. Try any exercise for a couple of weeks at 30 minutes 4 days a week and then 45 minutes 4 days a weeks for the next two weeks. By the fifth week you should be used to doing the exercise and should be able to commit to the hour long sessions quite easily. Now here is the rub. If you did this I would guess that you would loose about 0-5 lbs for all that work. Anything more than that would be super excellent, but dont hold your breath about it.
It also takes your body some time to adjust to the new changes in exercise.
Once you have gotten to an hour a day workout sessions, consider this formula. If you workout more than 4 days a week you will loose weight for that week. If you work out for 4 days a week you will maintain your current weight. If you work out less, you will gain weight. Sad but true.
I dont know how well you will go with your walking, but try hard and get through the first few weeks to get yourself on a schedule. Seriously this is the hardest thing, integrating positive changes into your life. ! Going from no exercise to some, takes time for your body to learn and your mind to grasp, but it is worth it.
Now here comes the serious weight loosing training. Once you find yourself working out, you now have some options. If your knees can take it (I am concerned about your size), try to get on a tread mill or add some running and sprinting to your routine. You will find some great results once your body can maintain the HITS system. (high intensity training). It also will improve your cardio heartrate, overall fitness and should slim you right down. (if not get into a pool !)
The next exercise step is to integrate weight training into your workout. Now lets say you cant afford weights, well then learn how to do squats. Drop to your knees, kick out and then back and stand up. Go to google and find other squats. They are the best.
But if you can find weights then look into resistance training. Any good weight trainer will tell you that you build muscle in the negatives. Another good life tip is that weight lifting is boring and sucks. Unless you are going for a chiseled bodybuilder lifestyle (no offense it is awesome-just not for everyone) weights are often used wrongly. With that as your starting point and with me purposely withholding information so you dont get hurt, the only manner I recommend for you do use weights is at very low sizes and as many repetitions as you can manage. Try and bench 25lbs for 3 sets of 50 (or more).
What will happen is you will build that muscle and you will learn what the weight do. LAter check google "how to increase your bench press by 50lbs by Shawn Phillips at muscle media.com" and follow it to the letter. Then using the same logic apply it to the way you exercise with weights throughout your whole weight lifting journey.
Swimming and stretching. My best advice is Stretch,Stretch,Stretch,Stretch,Stretch,. Take yoga, Stretch,Stretch,Stretch,. Whatever. there is some serious strength in it and since I can barely grab my own hands behind my back (but I have strong shoulders !) I can recommend it! Besides actually stretching, swimming is a good exercise that can be integrated into your lifestyle and will help you maintain a good body.
Last thing about exercise, do not do it more than 3 days in a row and do not do it 7 days a week. Always rest for at 1 full minute between reps and always stretch before and after a workout.
Also remember that even if you give up after 20 minutes, at least you still went to the gym and guess what you will go back and you will do better sometime in the future. Even a little step in a positive direction is a step in the right direction.
Now for the eating. Try this. Dont give up anything you are eating yet. But try to figure out what you are eating that is bad for you.
Your first step should be trying not to eat anything bad, but when you do, drink a full 8oz glass of water right after. In fact try to drink at least 2 liters of water each day, plus all the extra glasses you have for pizza and candy bars .
Water is the one supplement that actually helps your body function. In fact almost all the processes that occur in your body work way better when you are hydrated.
Your next step is to start replacing bad stuff with good stuff. Or if you are just not able to do that, just add some healthy stuff to what you are eating. When you eat a pizza, also eat a few heads of broccoli. When you eat the pasta, add in some tomatoes and onions. Later when you get a handle on your diet, you should be eating a good balance of protiens, carbs, and vegetables. The best way to drop calories in a regular persons diet is to replace high calorie foods with vegetables that are fibrous and not full of carbs (not peas, not corn but califlower, broc, spinach, cabbage -look this up ) Its a bonus if they are on the antioxident list !
So if you where to take a pasta dinner and take out 1/2 the pasta bit then add 1/2 (or more ) of good for you veggies, you will reduce the calories, add some health to yourself and loose the weight. You still will eat what you like, but you fill up on fiber and its passed out later (expect gas ).
I feel like I have presented too much information for you here already, but the bottom line is hit it as hard as you can but do it as smart as you can. If you go balls out in the beginning, you will inevitably falter, get hurt and most likey quit. (true for diet and exercise)
So challenge yourself to build up to making changes and once you are doing that, keep learning and trying more things that will help you get there. Accept that this will take some time and try to remember that your body also needs rest ( I take off 1 week every 4weeks) The same is true for dieting. Try and be good for 6 of the 7 days but give yourself some freedom at least one day of the week. Later when you are actually in the exercise, lifestyle game you will find out the steps that suit you and get you to where you want to go.
Anyhow, Good luck. I am really rooting for you !
