What Impacts the Metabolism + 3 Strategies to Speed it Up

If there were one general theme that comes into focus as we get older when it comes to our health, it would be “the metabolism”. And, as a Thrive Coach, it’s normal to hear things like “I’m old so my metabolism is slower” or “how do I speed my metabolism up” or “my metabolism is making me gain weight”.

It’s important to understand what exactly your “metabolism” is and how it works! This way, you can understand what actions you can take to overcocme the slowing metabolism. This article is going to answer those questions, as well as a few more, so that you can be successful in your health and fitness goals.

What You Talk About When You Talk About the Metabolism

It would seem that our metabolism is a mythical, mysterious creature. It is elusive, evasive, stubborn and many other adjectives that we can use to describe it. Or so we think. When we talk about our “metabolism” what we are effectively referring to is our Resting Metabolic Rate (RMR from here on).

Your RMR is the amount of energy (calories) your body burns at rest. For instance, the average person will burn about 1,500 calories if they did nothing all day. So, if you sat from sun up to sun down, you would burn about 1,500 calories. This is because your body still uses energy (calories) to maintain homeostasis (body temperature, pH balance, blood flow, etc.).

So, Does Age Really Have Anything to do With This?

Sadly, there are certain things that we can’t change that put a damper on our metabolisms. Women, for instance, NATURALLY have slower metabolisms than men (sorry ladies!). This is mostly because women typically have less lean body mass. This is also why wives get mad at their husbands when the men lose more weight.

You can also thank (or throw things at) your parents. Your genes play a huge role in your metabolism. Some people are naturally more sensitive to certain macronutrients and therefore have to pay closer attention to what they eat. Others, like my wife, can eat a carton of ice cream and lose 2lbs.

Your intuition would tell you that age also plays a part in this process. But there is more to that story than meets the eye. As you age, you get frail, eat less, lose muscle and have trouble going #2…because you STOP MOVING!

When you get to retirement age, you think it’s time to shut it down. No more work, no more movement, no more life. Think of your grandparents (at least the average). They sit at home, watch The Price is Right and call every once and a while to tell you that the dog next door pooped in their yard again. If this is all you did at the age of 30, you would become frail and brittle by 40.

3 Strategies to Overcome the Slowing Metabolism

So, if movement, or lack thereof, is the reason for a slowing metabolism, then the logical thing you need to do is move more. And while that would be a great start, there are other strategies you can implement to ehnance your chances of keeping your metbalism under cotrol, verse letting it control you:

Resistance Training

Your RMR is the calories you burn at rest. Considering that the vast majority of us are at rest most of the day (not literally sleeping, just not actively moving), this is where you can have the greatest impact. The ONLY way to do that over the long haul is by adding muscle. The ONLY way to add muscle is to do resistance training. You’ve heard the saying “muscle burns more than fat”. Well, considering fat burns nothing and muscle burns something…well, you get the point. Not only will resistance training help increase lean mass, it will also keep you from becoming frail and brittle as you age. Double Bonus!

Eat More Protein

There is a reason you go on a high protein diet to lose fat and not a high carb diet. Because of its structure, protein requires more energy to metabolize than carbs or fats. Therefore, eating more protein will increase your metabolism (at least for the short term).


Sleep has this amazing way helping us lose unwanted body fat…if we do it correctly. In short, when you sleep, your body replenishes it hormones. When you don’t sleep, it doesn’t replenish them completely and increases cortisol. This double whammy kicks your metabolism down and puts your body into fat storage mode. Sleep more (and better), lose weight. Pretty easy!

These are great first steps to getting your metabolism back on track and revving that it did in high school. Don’t be fooled by the propaganda. You can get your metabolism going again. Start moving, eat the right stuff, lift heavy weights and sleep!
