I haven't seen any new responses by the OP.
Should 6footminnow return, just wanted to leave this response:
You must continue on this journey. Recognize that Doctors are great for treating sickness - but unless they are into fitness themselves, they really aren't equipped to advise you on nutrition or much else; that's not what they handle in medical school. You are pretty much on your own.
Rome was not built in one day. Nor can you get where you want to be in a short time, either. But you can (and are) taking steps towards your goal of being more fit than you are now.
I would suggest you first try to identify your basic metabolic rate - the amount of energy you spend when you do nothing but lounge around the house. There are a number of sites online that can give you a good guess. Depending on your rate of exertion, weight/height - (can't trust the C2 calorie tracker - it seems to be designed for 165# men) - your calorie burn in a session is going to vary. If you can get your hands on a Fitbit, or a some other fitness tracker, you'll then have some type of guess as to how many calories you're burning in a session. Add that to your basic metabolic rate, and then you'll know how much you can eat without gaining weight. Subtract 500 to 1000 calories from that, and you'll know how much you can eat to lose weight.
For best results, you'll want to be sure you consume plenty of protein to help maintain your muscle mass. Fats are fine, with proteins. Carbs are fine, with proteins. Try not to mix carbs and fats. You certainly can - you won't die - but for weight management purposes, I wouldn't advise it. That said, we're all different, so it could be that what is healthy for one of us might be unhealthy for you. You'll have to use your best judgment. If you keep a food diary - log what you eat, when you eat it, how much, etc - then you can see at day's end how you've done. That is the only thing that ever worked for me - logging what I ate. If not, I suffered from calorie amnesia and forgot certain snacks here and there through the day.
I know money is tight, but you may benefit from a group fitness class to help encourage you. Exercising alone is convenient, certainly cheaper - but it can be a lot tougher to suffer through a hard workout without others struggling along side you.
Keep at it. The only failure is when you put the handle down for good.
