Get rid of all your chairs, couches, etc.
What works will be very person dependent.
But if you want to lose weight, despite everything that you read that wants to make this complicated, it is 93.72% simple:
Eat less than you burn. Almost no one wants to hear this and so when someone says it they get slammed.
Exercise helps. But 15 minutes a day is not enough. Make it an hour a day hard or 90 minutes easy. Park a mile from work, there is an easy 30 minutes, 15 minutes each way. Walk for 30 minutes at lunch. Now you are up to an hour and you have not broken a sweat. Run or jog, go to the gym work hard for a mere 30 minutes and there is your 90 minutes. Take a 5 min walk break every hour at work, something like 40 minutes, combined with that 30 coming and going to the car and you 70 minutes without hardly trying. The key is don't just sit for hours; keep moving.
Eat less. I have dieted twice in my life, doing so currently because over 15 years or so I drifted up at the all too common 1lb or so a year, starting from 143lbs, 5'8", 3:39 marathon at age 40). I am down 11lbs without too much work due to a modest increase in exercise above my background rate (I exercise hard frequently in general) and eating less/better. Simply trying to be a little "better" about eating does little for me. But if I track calories I have a daily goal and for me that makes actually cutting back much easier. YMMV.
But simply running more and eating less can also help you lose muscle mass. So, I started lifting. Actually started that before dieting. Hard to get much stronger while restricting calories, but I find I am gaining a small amount, so at least not losing muscle while losing weight. Also, large group of muscle lifting (as opposed spot lifting like curls, etc.) increases metabolism, so that helps too.
So in summary, near as I can tell, there is no easy way, but there are three clear steps that if you follow you have a very good chance of some success.
1) Keep moving, a lot. Don't sit on your fat butt and you won't have a fat butt.
2) Modest restriction of calories, eat healthy foods, skip junk.
3) LIft weights to maintain muscle mass.
This is not rocket science, but is hard because we as a society are too sedentary, and think huge portions of calorie rich foods are normal portion. You work, get tired, have a nice comfy chair in front of the TV with a bag of chips right there on the counter, and points 1-3 can wait until tomorrow. If that is you, an exercise buddy can help, or a personal trainer. Having a spouse also living the exercise and healthy food life is very helpful, "Honey are you sure you don't want a third helping? It is your favorite and I worked hard to make it just for you!", not so helpful.
That is my 2 cents. Might only be worth 1 cent.
We live a world with knowledge of the future markets has less than one significant figure. And people will still and always demand answers to three significant digits.
