Ask Amanda: Max Your Metabolism

After (semi) lecturing a client about why it was important to lose body fat BUT maintain lean muscle (even if the “weight” on the scale stood stagnant because of it), she looked me straight in the fact and said, “So this whole process is just about building a better metabolism?”

I wanted to hug her.  “YES,” I cried to my dear and startled client, “YES IT IS!”  

And herein lies one of the most obvious but most misunderstood connections between exercise, body composition, and nutrition: metabolism.  Scientifically, metabolism is the sum of all the chemical processes inside our body that help us maintain life.  In layman’s terms, metabolism is the way in which your body converts and uses energy for fuel.

So why does this metabolism stuff matter to those of us out here in the streets, just trying to get fit?

There are lots of reasons.  Your basal metabolic rate (BMR) refers to the amount of calories your body burns at rest – and the higher your BMR, the less you have to do to actually burn the energy (read: food) you consume.

People with a greater muscle-to-fat ratio have higher BMR, even if their weight is exactly the same as someone with more fat than muscle.  Men tend to have higher BMR than women (sh*t, they win again!).  And people who go on starvation (VERY low-calorie) diets, even temporarily, can actually permanently decrease their BMR by sending the body into a “starvation mode” and causing it to hold onto energy and store it as fat.

A bit exaggerated…but like, not much. #damnyoumen

In short: metabolism matters, and you definitely don’t want to mess yours up.  So what can you do to promote a faster, better metabolic rate?

First and foremost – SLEEP!  A lack of sleep, particularly when chronic, can lead to a neuroendocrine imbalance that not only makes the body store more energy as fat, but can also make you feel ravenous all day long (increased appetite hormones) and forget to tell you when you’re had enough to eat (decreased satiation regulators).

Second of all, lift weights.  I’ve talked about this time and time again, but the single best thing you can do to “speed up” (and I use this term loosely since you don’t actually change the metabolism itself but rather its efficiency in processing energy) your metabolism is to build lean muscle.  Every pound of muscle burns TRIPLE the amount of calories (six versus two) than the same weight in fat.  If you want to burn more by doing less (something appealing even to my least-active client), muscle is where it’s at.

Third – and this may seem obvious – eat food.  Your metabolism is like a gas grill, and it doesn’t spark a fire without fuel.  When you don’t eat enough, not only does your body think it’s starving (and start holding onto every bit of energy/food you DO put into it), it starts to cannibalize your precious muscle tissue (SEE ABOVE) for energy – not good. What you eat is also important – protein is the best muscle-retaining macronutrient out there, fiber can rev up the fat-burning process even more, and staying hydrated (with water, by the way) makes all of your body’s most vital processes run smoothly and more efficiently.

Finally, be a mover (and heck, while you’re at it, a shaker).  Separate from the resistance exercise I mentioned above, what scientists are now calling NEAT (non-exercise activity thermogenesis) can actually be more effective in helping you lose weight and build fat-burning metabolism than “actual ” exercise.  Everything from fidgeting to taking the stairs up to your office to standing instead of sitting to take a phone call counts as NEAT, and in very active individuals, their NEAT daily calorie burn is more than what most other people might burn in a 30-minute elliptical session (something many people mistakenly consider a “workout,” which is a topic for another time).

The combination of what you eat, how you move, and your other lifestyle factors (sleep, stress, etc.) is mostly responsible for how efficient your metabolism works – but don’t discount the “big G-factor” known as genetics (womp womp, I know).  If your family is prone to PCOS, Cushing’s Syndrome, diabetes, or thyroid issues, or if you’re on certain antidepressants or other medications, your metabolism may be slower than most – and it’s out of your control.  But even with these clients, I always encourage them not to use their medical conditions as excuses to be lazy with diet an exercise – but rather as a catalyst to rise above what they can’t control and focus on what they can (clean eating, regular workouts, and a positive mindset).

Do you think you have a “fast” or a “slow” metabolism – and do you personally believe it can change over time and/or with lifestyle habits?

  1. Excellent post! Loved the info on metabolism and NEAT.

    I assume my metabolism is relatively fast since I’m able to maintain my weight fairly easily (still takes a lot of vigilance though!). I do think it can be improved within the parameters and limits of one’s genetics, but I’m not any sort of expert in that area. I do think it changes seasonally for me because keeping weight down is much easier in summer when I’m outdoors and moving much more “normally” rather than spending hours per week doing indoor aerobics.

    I’ve always been a NEAT ‘”freak,” I suppose. I take stairs instead of elevators when I can, etc. I even walk upstairs to use the bathroom in our house when I’m downstairs and can use the one on that floor just to get in several extra flights of stairs per day. For work breaks at home, I’ll often walk from my office to the basement and back (two floors) each way for about five minutes each hour or so.

    Shoveling snow in winter is a pretty good weight/aerobic/NEAT activity, although it doesn’t happen on a regular schedule here in MN. But when we do get a big snowstorm, I try to avoid using the snowblower by shoveling small amounts in several sessions (2 inches or so) instead of waiting till the snow ends and either killing my back shoveling 6 or 8 or 10 inches or wimping out and using the snowblower. It takes me about 15 minutes to clear my driveway. I move fast, use legs, arms, back, and core to move the snow, and then do it again in an hour or two.

    Walking 18 holes on my regular golf course is sort of NEAT. It’s a relatively hilly course, but with some flat holes. Hitting the ball, then walking briskly for a few minutes (especially up our steeper hills) gets my heart rate up, then I catch my breath, hit the next shot, walk, etc. On each green, I catch my breath when I’m putting, then on to the next hole. Lather, rinse, repeat. Eleven of the 18 holes have decent hills on them (and a couple of killers on the back nine), so I get a pretty good “interval training” aerobic workout because I can more or less coast on the flat holes.

  2. I LOVE the term “NEAT freak” – I am going to use that in my next presentation, so thank you! I’m the same as you – I make a commitment to taking the stairs in the subway stations (and walking if I have time and don’t absolutely NEED to use the air-conditioned comfort of the subway or bus), I live on the fourth floor of my building (no elevator; no choice), and I am lucky to have a job that requires standing and lifting heavy things multiple times per day – not too shabby. Snow shoveling though, well….can’t say I’ve ever had THAT form of NEAT before! 😉
