Keep reading as we take a closer look at how your metabolism is affected by age and the secret to speeding up metabolism after 40.

What is Metabolism?

Metabolism is the process by which the body converts food into energy. The vital functions associated with metabolism are beating of the heart, different functions of the brain, digestion, and respiration.

The pathways of metabolism depend upon nutrients that they break down to produce energy.

Metabolism is quantified as the pace at which the body burns off calories. Weight loss is dependent on burning off more calories than you eat. Higher utilization rates might help consume energy that your system gets stored as fat.

How to increase your metabolism after 40

As you progress through different stages of life, your metabolism can go through changes. Primarily, your Basal Metabolic Rate (BMR), the energy required for basic bodily functions at rest, tends to decrease with age. This decline is attributed to several factors.

One significant contributor is the natural decrease in muscle mass and a slight increase in body fat percentage that often occurs as you grow older. Muscle tissue is inherently more metabolically active than fat tissue, which means a reduction in muscle mass can lead to a lowered BMR.

Hormonal fluctuations also play a role, as levels of hormones such as testosterone in men and estrogen in women decrease with age, impacting muscle mass and fat distribution.

Physical activity levels tend to wane over time due to various life responsibilities, affecting both muscle mass and overall energy expenditure. If you are wondering whether there is anything to improve your metabolism, then you are in luck. You are about to learn how to boost metabolism after 40 naturally with our tips below.

1) Green Tea

2) Sleep Well

As if we need an excuse for a lie-in! There is growing attention and signs that sleep reduction and sleep ailments have a substantial effect on metabolism.

6) Exercise

It may sound challenging, but exercising daily can in fact improve your metabolism. How does it work you may ask? Exercises to increase metabolism such as running, swimming, aerobics, and walking helps you burn calories and can even temporarily suppress your appetite post-workout.

Weight training also plays an important role. As you gain muscle mass, your body’s resting metabolic rate (RMR) increases. Muscle tissue is metabolically active, meaning it burns more calories at rest compared to fat tissue. This means that even when you’re not exercising, your body burns more calories just to maintain your muscle mass.

7) Detox your liver

Alcohol’s impact on the liver goes beyond merely interrupting fat metabolism; it can have profound consequences on liver health and overall lipid metabolism. When alcohol is consumed, it undergoes a multi-step process of breakdown, primarily occurring in the liver. This process has several significant effects on the liver’s function, including its ability to regulate cholesterol and fat levels in the body.

8) Manage stress

High stress levels can contribute to a slower metabolism, resulting in weight gain. Cortisol triggers your fat and carbohydrate metabolism, leading to a surge of energy within your body. While crucial for survival scenarios, this process concurrently amplifies your appetite.

Furthermore, heightened cortisol levels can give rise to desires for sugary, fatty, and salty foods. As a result, you’re more likely to crave and indulge in fast food and sugary snacks rather than a healthy balanced meal.


In this article, we have taken a deep dive into how to speed up metabolism after 40. By making a few simple changes to your lifestyle and diet you can start to improve your active metabolism.
