The Bottom Line on Belly Fat

/in /by

Our pretend daughter Jamie slow-cooked a roast for Memorial Day, and it was delicious, the best she’s ever done. She does them very well to begin with, so what made this one so good? Fat. It was a chuck roast. What made it so good was not the fat that you could see, it was the intramuscular fat you really can’t see when it’s cooked. The marbling you see before cooking? That’s more like what I mean, but some fat is so woven into the muscle you can’t see it even then. Why on earth am I talking about chuck roast? It’s because we humans are well marbled as we age, but in our case, it’s not a good thing.

I’ve told you about subcutaneous and visceral fat, but there’s one more type: intramuscular fat. Because we are so sedentary, we have plenty of it, and the more sedentary we are, the more intramuscular fat we have. While it could be a readily available supply of fuel, it’s a sign of muscle loss and sedentary living.

How can we tell whether our fat is located under our skin or around our organs? The only definitive way is with a CAT or PET scan. Dual energy x-ray absorptiometry (DEXA) can be used to determine body fat, but it’s not as precise on the location.

Let’s make it simple. Stand up. Contract your abdominal muscles as tight as you can. Now grab your belly fat, opening your hand as far as you have to get a good hold. If you seem to have more fat in your hands but there doesn’t seem to be much under the muscle, you most likely have more under the skin than under the muscle. If you can’t grab much fat in your hands but you still have a large waist, it’s mostly visceral fat.

While not exactly a scientific method, it can give you an idea of where you stand. And this doesn’t count the marbling effect. For me, it’s almost all subcutaneous fat I can grab.


The Bottom Line

How do you get rid of belly fat? Eat less. Eat better. Move more.

Yes, you’ve heard that before, but here’s why it’s the solution to this problem:

  • Eating less will help you lose fat from under the skin and under the muscle.
  • Eating better means you will be eating fewer refined carbohydrates, and that can benefit your visceral fat.
  • Exercise will help the intramuscular fat because you’ll use it as fuel. It will help the subcutaneous fat because you’ll be burning calories—and yes, do your crunches and leg lifts to strengthen your core. But the visceral fat will benefit the most from exercise because exercise can help use the hormones it produces and move your metabolic function more toward normal.

Find a way to eat less, eat better, and move more that suits your lifestyle. It may be completely different from what works for your best friend or your Aunt Mary, but it will work for you. For many people, my Optimal Performance Program is helping them achieve results they haven’t gotten any other way. But whatever approach you use, you must do something; when I say the guy in the photo has a killer belly, I mean it literally. The answer isn’t a pill or a special food; it’s the effort you put into it.

The Dangers of Undercover Fat

/in /by

What’s lurking under your abdominal muscles, in and around your liver and other internal organs? Undercover fat, actually called intra-abdominal or visceral fat. It’s dangerous because visceral fat is more metabolically active and increases the risk of heart disease and type 2 diabetes among other diseases.

What does “metabolically active” mean? Primarily, this fat makes more chemicals that can impact other organs in a negative way: protein, fat, and cholesterol-based hormones such as cortisol, insulin, and estrogen. These chemicals are critical to our health but in excess amounts can result in insulin resistance, fatty liver, and excess estrogen in women and men.

How do you know what type of fat predominates in your body? Better yet, is there anything you can do about it? We’ll finish this up on Saturday.

“Sit-Ups Make You Fatter”

/in /by

When I spot a headline like that, I have to click on it to see what they’re talking about. And I usually end up disappointed because it’s about some product to help you lose belly fat. What about the sit-up claim? They say doing crunches or sit-ups or leg lifts will make the muscle under the fat bigger, thereby pushing the fat out farther, and giving you the appearance of being fatter.

Baloney. Sit-ups won’t make you fatter and those products they’re pitching won’t help you lose belly fat. But it does merit a look at the types of fat, where it’s stored, and what you can do about it.

The most obvious fat is the type you can see and pinch: subcutaneous fat. Literally, that means it’s right under the skin. We can see the rolls and bulges. It doesn’t make us happy and, in fact, can make us feel bad about ourselves. I can’t tell you to stop feeling that way because I feel the same way at times.

But there are two things that are important about it. First, it’s a form of protection against famine; not that famine is likely on this continent, but it’s a reserve energy supply. Second, it’s not as metabolically active as intra-abdominal fat, which is found underneath the abdominal muscle. I’ll talk more about that on Thursday.
