Perhaps you have been feeling more tired than usual lately. Maybe your digestion seems a bit “sluggish”. Your skin feels dry and you’ve been craving sugar. These are all signs of metabolic weakness or a slowing down of your metabolism. Let’s dive into how this can happen and for each cause I give simple to implement tips on how to increase your metabolism.
Metabolism includes all of the reactions in your body that use nutrients and oxygen to create energy. There are lots of factors that affect how quickly or slowly it works. Your "metabolic rate” is measured in calories.
We now know that metabolic rate is much more complicated than the old adage “calories in, calories out”! In fact, it's so complicated I can only list a few of the common factors that can slow it down.
Examples of common reasons why metabolic rates can slow down:
We'll briefly touch on each one below. It is so much more than the old “eat less and exercise more” principle.
Your thyroid is the master controller of your metabolism. When it produces fewer hormones your metabolism slows down. Some of your thyroid hormones tell the cells in your body when to use more energy.
Ideally, they would work to keep your metabolism just right. However, issues like autoimmune diseases and mineral deficiencies can throw them off balance. Two of the most common minerals are iodine and selenium.
To keep these minerals at optimum levels include some of the following foods into your diet each day to help balance your thyroid hormones and increase your metabolism.
I eat 3 brazil nuts every morning when I get back from my walk. Boom! Daily selenium is taken care of.
Foods containing iodine: Kelp, wakame, kombu, organic strawberries, organic yoghurt, cranberries.
Foods containing selenium: Brazil nuts, sardines, turkey, spinach, chicken.
Talk with your doctor about having your thyroid hormones tested.
When people lose weight their metabolic rate often slows down. This is due to the fact that the body senses that food may be scarce. It adapts by trying to continue with all the necessary life functions and do it all with less food.
While dieting can lead to a reduction in fat it carries, unfortunately, it can also lead to a reduction in the amount of muscle you have. As you know more muscle means faster resting metabolic rate.
In general, larger people have faster metabolic rates. This is because it takes more energy to fuel a larger body than a smaller one.
However, you already know that gaining weight is rarely the best strategy to increase your metabolism.
Muscles that actively move and do work need energy. Even muscles at rest burn more calories than fat. This means that the amount of energy your body uses depends partly, on the amount of lean muscle mass you have.
Tip 2: Do some weight training to help increase your muscle mass. Start small with only a few reps and build up to heavier weights and more reps.
Which leads us to...
Aerobic exercise temporarily increases your metabolic rate. Your muscles are burning fuel to move and do “work”. This doesn't mean you need to go crazy and start running or doing fast gym workouts. Aerobic activity can be as simple as a brisk walk up the nearest hill.
Even little things can add up. Walking a bit farther than you usually do, using a standing desk instead of sitting all day, or taking the stairs instead of the elevator can all contribute to more activity in your day.
Tip 3: Incorporate movement into your day. I often will run on the spot rather than stand and wait for the jug to boil or my toast to cook. Any amount of activity is better than none.
There is plenty of research about the influence that sleep has on your metabolism. The consensus is to get 7-9 hours of sleep every night.
I have written a lot about the benefits of a good night’s sleep. Probably because it can elude me at times too. This is one area to work hard on maintaining but in doing so try not to get stressed or you will find yourself in a vicious circle. See my latest post on sleep (it does refer to midlife but really the concepts are the same at any age) - How To Get A Better Night's Sleep In Midlife
Tip 4: Create a calm nighttime routine that allows you to get into bed in a relaxed state in time for 7 hours of sleep. Ideas to do this are:
And so finally we come to:
Stress really is the Big Kahuna for messing up our body's processes and slowing your metabolism.
It is important to keep stress to a minimum. If you find your stress levels getting a little high, try some regular meditation. Even 10 minutes will help. There really are some gorgeous meditations online. Check out this post for some of my faves - Free Guided Meditations For Better Health In Menopause
Although a little cortisol, the stress hormone, can increase your metabolism chronic stress can cause weight gain, depression and fatigue.
Tip 5: Check out my Selenium-Rich Chocolate Chia Pudding recipe. This recipe contains Brazils which is are a rich source of selenium which can support thyroid function and help with sleep problems.
Other ways to reduce stress are to:
can become slow for many reasons but it is fairly simple to increase it with the tips I have given you. As with anything in health the best remedy is a holistic approach. My personal approach to remedying a health issue is to tackle it in small increments. Change something in your diet this week. Next week maybe add in a short meditation. Ten weeks equals ten changes for the better and that's ten habits you didn't have when you started. Imperfect action is better than no action.
Do you know if your metabolism is slow?
