Some you the suggestions talk like the gym is right across the street. May be in some case but I bet 98% of the people reading this would have to travel a good distance to get to a gym and then only a school gym. Lifting weights will work to a point. Problem is that once you start you have to keep doing it, forever. When the time come you have to quit due to age, disabilities, etc. then what? ? For some the problem is their occupation. Sitting behind a desk or a steering wheel day in and day out sure don't help the weight situation so they HAVE to do something to keep healthy. I live on an acreage, retired at 76, cut firewood in the fall and burn it in the winter. That gets handled 3 times before it makes heat. Plus a thousand other cores that need doing. No problem staying active and eat the same year around, meat taters and gravy is my first choice. Will pick up about 10-12 lbs during the winter and that will come off in the spring, in fact it has started already. Keeping active is the big part of it and that is all your doing by the lifting and gym bit but you don't need to drive or buy weights to do it. Everyone's body is different. Don't let your weight get out of hand in the first place and your won't need all the rush rush stuff to correct it.
