I’m Approaching 40 and Getting Belly Fat: What’s Up With That?

During every workshop, seminar and lecture I’ve ever given to an audience of women at least one raises her hand to ask a question about belly fat.

The typical conversation flow is as follows:

Woman: “How do I get rid of this?”—As she points to her midsection.

Me: “With exercise and healthy eating habits.”

Woman: “But, I do that.”

Me: “Hmmm, well are you over the age of 40?”

Woman: “Yes!”

This correspondence generally kicks off a very lively discussion on why belly fat appears and why it’s so hard to get rid of.

Eyes and ears open when I emphasize one simple fact: If you’re over the age of 40 you will naturally accumulate excess body fat in your midsection. And, this increase in belly fat is linked to three changes that we as women will all experience as we approach menopause:

  1. Shifts in the estrogen to testosterone ratio
  2. Slowing of the metabolic rate
  3. Reductions in lean muscle mass

I’ll break each of these down in the following paragraphs.

Shifts in the estrogen to testosterone ratio

In our early childbearing years, the female sex hormone estrogen predominates. This hormone inherently promotes body fat accumulation in the lower half, particularly around the hips and thighs making us appear more pear-shaped, compared to our male counterparts.

Now, as we age and approach menopause, our estrogen levels begin to decline causing more of a predominance of testosterone, which is the dominant male sex hormone.

Testosterone is responsible for the development of masculine characteristics like facial and body hair, lean muscle mass, and erection capabilities. In light of such changes in hormonal status, it’s no wonder why many aging women start to observe the presence of miscellaneous facial and body hair, and also tend to experience a suddenly increased sex drive.

Unfortunately, this menopause-related testosterone predominance is also associated with increases in the accumulation of what’s called visceral fat. This type of fat lies deep in the belly region behind the abdominal muscles.

So, essentially, as women age, excess body fat starts to shift away from the hips and thighs to the belly area. This process generally occurs around the age of 40 but can also occur as early as the 30s. As a result women begin to appear more apple-shaped tending to carry excess body fat in the midsection.

But, it doesn’t stop there!

Changes in the metabolic rate also occur simultaneously.

Slowing of the metabolic rate

The metabolic rate (or simply metabolism) is the rate at which the body inherently burns calories to fuel vital functions. Metabolism is generally influenced by factors like height, weight, and physical activity levels. The metabolic rate is naturally lower in women when compared to men but with aging, there’s a natural decline in both sexes.

This lowering of metabolism makes it that much more difficult to burn calories and, therefore, promotes unwanted weight gain.

As a result, many women (and men) who were naturally thin during childhood and early adulthood (up to 29) begin to notice an appearance of stubborn body fat, usually around the 30-35 year mark. This effect is greatly augmented in people who are physically inactive.

Interestingly enough, the decline in metabolism during aging is closely linked to reductions in lean muscle mass.

Reductions in lean muscle mass

Lean body mass refers to any “non-fat” tissues in the body including bone, muscle, organs, blood, and water. Of all components of lean body mass, muscle is the most adaptable to change, which is why I’m discussing it here.

Unbeknownst to many, declines in muscle mass generally start in the 30s. As such, it’s much easier for a woman to accumulate excess body fat, even if she were lean all her life.

Unfortunately, such declines in muscle mass with aging are inevitable. But, fortunately, the rate at which declines occur is absolutely amenable to exercise, especially resistance training (weight lifting). This is especially important to understand, particularly if you are one of many women who tend to shy away from this type of training out of a fear of becoming too bulky.

What you do about this belly fat dilemma

Believe it or not, while shifts in our estrogen to testosterone ratio, slowing of the metabolic rate, and reductions in lean muscle mass are inevitable effects of the aging process, there is light at the end of the tunnel.

With the right combination of exercise and sensible eating habits before, during, and after menopause, women can substantially delay the rate at which these processes occur and, as a result, reduce the amount of belly fat that accumulates.

So, what is the right combination of exercise?

Well, the best combination involves cardiovascular (cardio) exercise along with regular resistance training. Exercises like brisk walking, jogging, running, biking, stair climbing, and cardio group exercise formats are necessary for burning excess calories and reducing general body fat accumulation.

Although you can’t selectively choose where you lose body fat, you can choose cardio exercises that thoroughly engage your midsection (jogging or running, swimming, and cardio kickboxing) in order to promote significant reductions in belly fat.

And, I must also emphasize that higher intensities of cardio exercise become increasingly more important with age.

In other words, you’ll need to put in some real work for some real results. Many women over the age of 40 find it difficult to control belly fat, and body fat accumulation in general, because they just aren’t exercising intensely enough.

Now, compared to cardio exercise, you generally won’t burn as many calories during a typical resistance training session. However, this type of training supports increases in lean muscle mass and greatly boosts the metabolic rate which’ll ultimately lead to increases in calorie burning potential and more effective weight management over time.

Another plus of resistance training over the age of 40 is that the natural shift to testosterone predominance actually works to a woman’s advantage.

As I mentioned before, testosterone is the dominant hormone in men that allows them to develop more lean muscle mass. Due to elevated levels of testosterone during and after menopause, aging women can greatly maximize muscle mass with weight lifting in ways that give the body a more sleek, firm, yet shapely appearance.

The final key to controlling excess belly fat during aging involves sensible eating habits.

A healthy, well-balanced diet coupled with calorie management is key. Women should regularly consume adequate amounts of calories from all the macronutrients (carbohydrates, fats, and proteins), as this helps keep the metabolic rate in check.

It’s especially important for aging women to take in enough high-quality carbohydrates from vegetables and fruits, legumes (beans, peas, and lentils), and whole grain foods along with sizable amounts of healthy fats in the forms of oily fish (salmon, tuna, sardines, trout, and mackerel), nuts and seeds, fatty fruits (olives and avocado) and their oil derivatives (extra-virgin olive oil).

Sufficient protein intake is also critical for fueling metabolism and maintaining lean muscle mass. Some of the best sources include lean meats, fish and seafood, poultry, fat-free dairy products and/or whole soy foods.

Finally, for belly fat prevention and overall weight management, it’s important for women to constantly burn more calories than what’s consumed day-to-day. Make it a practice to regularly monitor your calorie consumption and expenditures to avoid unwanted weight gain.

This is especially important if you naturally gain weight easily or are genetically predisposed to having an apple-shape.

So, now you know what’s up with that belly fat that comes with aging. You also know what you can do about it! If you follow the recommendations I’ve provided here, I can almost guarantee you’ll be able to reduce the amount of belly fat you accumulate before, during, and after menopause.

Before starting an exercise training program you should first make sure that exercise is safe for you. If you are under the age of 55 years and generally in good health, it is probably safe for you to exercise. However, if you are over 55 years of age and/or have any health problems, be sure to consult with your physician before starting an exercise training program.
