People are going to immediately hate on this suggestion because barely anyone in America would ever contemplate doing this. But I have personally done it, it works, its fast, its healthy, and its actually really easy.
Juice fasting (With organic vegetable and fruit juices and water). Obviously look up the details first, but this is the easiest and safest way to lose weight. Easy because you don't have to do ANYTHING, its all about what you don't do. I juice/water fasted for 22 days (Which may have been too long considering I was not overweight to begin with, I just did it for detoxification purposes). Anyways, I lost 21 lbs in 22 days. For me this was excellent in the long run, because it slowed down my metabolism and helped me get up to a higher weight. If you're overweight, it will speed your metabolism. It is very balancing. Also, it is MUCH easier for someone who is overweight to fast because the fat will continually provide you with energy. And no your muscle do not waste away. Fat wastes away first. I did temporarily lose a minute amount of strength WHILE fasting, but afterward it returned immediately. After the first 3 days, physical hunger disappears. If you REALLY want to do something, you can.
Just a suggestion, now let the haters who've never researched or tried fasting come attack me.
