If you had to lose 60 lbs..

I understand why you want to lose weight fast but that is still not a good reason to do something that could jeopardize your own health.

You also have not given your own stats like age, sex, height and current weight. Also lifting weights will also help you in your process to lose weight. Set a realistic goal with an actual plan and work hard at it.

I am 28 years old. I am male. I am 6 foot tall and currently weigh 295(ish). Lifting weights does help with weight loss, but it also adds pounds to my body. The BMI caculator doesn't seem to take that into consideration when it is calculating my BMI. Is that something that I should consider? Since what I am actually trying to achieve is a lower BMI.

The BMI figure you were given was for an average person. I can assure you that whatever you did with lifting weights, cardio, eating right would improve your BMI and general overall health. My BMI is like 31 right now. I'm 5'9" and 200 lbs with a a great deal of muscle mass due to very heavy lifting over a lifetime. My bodyfat percentage is around 18%. I assure you my BMI wouldn't even be a consideration in my "level of health" for a donation - nor would yours if you had a considerably lower bodyfat percentage. Professional bodybuilders have BMIs in the 50s. I'm not calling them the model of health but BMI is a skewed statistic for judging "health" if you exercise above average.

As others have said, see a doctor. See a nutritionist. Give them your goal, your reasoning, and they will help you with an exercise plan as well as an eating plan. As terrible as your father's situation is, yours is not much better. 300 lbs and 28 years old is no way to live to a ripe old age yourself. Do this for you and maybe you can help him at the same time.

I'd probably go to a nutritionist and explain the situation.

But I don't think it's doable... unless all you eat is pretty much lean meats, fruits and veggies. I know someone who had to lose a lot fast for surgery, and it's pretty much what he did (he regained it all after, but well it served its purpose).

Best of luck... I hope you find another match for your dad by then.

Any dent that you can make in those 60 lbs will be a big improvement.

I'm smaller than you (5.4 female, starting weight was 213) and have lost 19.5 pounds in 7 weeks.

I would definitely talk to your doctor. You may be put on a special diet that they use to prepare very overweight patients for surgery.

Get something like a FitBit Flex and a food scale. Track your food and movement religiously. Treat your water bottle like your wallet or phone: always with you. Don't go overboard with exercise and risk injury. Sustainable time will be more of your friend then intensity right now. I've been walking two hours a day (one in the morning, one in the evening) around our neighborhood and open space. My pace has improved, my route has gotten a little longer, and I don't need any breaks any more. I've just started adding short little sprints during the walk.
