Fighting 40s Flab
Metabolism is really only a small part of why it's harder to lose weight after 40. Age and life tend to conspire against.

But you don't have to wait for age to take its course, Fernstrom says.
"Even if we do have a small, let's say, biological sabotage built in, it does not mean everyone is destined to gain weight as they grow older. It's sort of an old wives' tale that you'll gain 30 or 40 pounds as you continue through middle age -- it can easily happen, but it's very easy to offset the change in metabolic rate," she tells WebMD.
"For most people that's going to be 100 calories a day approximately, and, you know, you look at 100 calories, if you are overconsuming just that 100 calories, you can gain 10 pounds in a year if you are out of sync 100 calories a day. So you don't have to have a lot of extra calories to have what I call weight creep."
Regular exercise is also key to getting metabolism back on your side, Peeke adds.
"The kind of physical activity that people are choosing to do in their 40s is nowhere near as intense as it's supposed to be. So to get over that metabolic speed bump we ask for an increase in intensity on the part of these happy campers. What does that mean? Instead of walking on the flat, throw in some hills. Ramp up the resistance on your resistance training, or for that matter the resistance on a cross-trainer. It's all the same."
