Essential Fats QA

O: What's the deal with fat? I thought it was bad, but now I keep reading about how I need it.

A: Too much saturated fat can be bad for you in that it can contribute to heart disease, but the fats known as essential fatty acids, or EFAs, are absolutely necessary for optimal health. EFAs can prevent heart disease, and they can enhance your ability to build muscle and even burn fat.

Studies have shown that EFAs can do everything from improving the action of insulin to decreasing muscle breakdown to increasing hormone production, specifically growth hormone and testosterone. They do it through a number of mechanisms, one of which is helping the body manufacture prostaglandins.

Where do you get EFAs? Nuts, seeds, fish and various oils can provide a lot of them, and even animal fats have some as well, but animal fats also contain loads of saturated fat, so don't overdo the steak and pork chops.

Science has recently discovered that the EFAs, including the omega-3s, -6s and -9s, are vital for health. You may have noticed that nuts are included in many diets in IRONMAN, precisely because they contain the EFAs that facilitate proper hormone production. For most bodybuilders, however, a balanced EFA supplement is also necessary for an optimal muscle-building environment, especially those who are restricting calories to stay lean.

O: There's a lot of new research on the essential fatty acids—-for example, indicating that they help build muscle and burn bodyfat. Would you elaborate on those points?

A: I agree with those who say that relative deficiencies of essential fatty acids—particularly omega-3 fatty acids—are becoming increasingly evident. Much of this derives from the fear of fat that's instilled by well-meaning but ill-informed "experts" who fail to differentiate good fats from bad fats. An example of bad fats would be trans fats, which are ubiquitous in our food yet have no value other than maintaining shelf life.

Among the benefits associated with fats such as omega-3s are increased insulin sensitivity even when people are on a high-fat diet, which normally promotes decreased insulin sensitivity. The increased insulin response favors lower bodyfat. Omega-3 fats also promote a tighter binding of IGF-1 to cell receptors, which favors an anabolic muscle effect. In addition, omega-3 fats comprise much of the fat found in the brain, and emerging theories show that a long-standing omega-3 deficiency may lead to depression. A recent study reported in Biological Psychiatry found that depressed people had brain levels of omega-3 s that were 40 percent lower than normal.

You may, however, want to avoid consuming an omega-3 source, such as fish or flaxseed oil, just before you go to bed. At least two substances known to induce sleep, interleukin-1 and prostaglandin D2, are inhibited by omega-3 fats, although they are stimulated by the omega-6 fats found in vegetable oils; i.e., linoleic acid.

Other studies show that a diet containing at least 30 percent fat is absolutely essential to testosterone synthesis in the body. This is particularly important for natural bodybuilders, who often favor diets of less than 10 percent total fat. Such diets, when combined with the increased Cortisol release that oc-

Omega-3 fats also promote a tighter binding of IGF-1 to cell receptors, which favors an anabolic muscle effect.

curs with extensive aerobic training, are a good way to induce a high level of muscle catabolism.

I think the emphasis should be on omega-3s and omega-9s, with a smaller intake of omega-6 fats. You do need some linoleic acid, since it can't be synthesized in the body. Anyone who uses a supplement such as flaxseed oil or borage oil, however, is well covered in this area.

O: I want your recommendation for the most anabolic legal sup -plement I can use—cost is no object.

A: Specific dietary fats. I know that isn't the answer you wanted. I imagine you were hoping that one of the exotic supersoluble pro-hormone gargling mouthwashes or the new spit-back-at-you creatines would be my anabolic top choice, but it's time to start thinking of fat as a supplement. Fat: disgusting, boring fat!

About three years ago a number of bodybuilding writers including Will Brink and myself proposed the idea of increasing performance by modifying an athlete's diet with more specific dietary fats, especially essential and monounsaturated fatty acids. Most of those new, lower-carbohydrate eating regimens were geared toward fat loss, and

they're still popular. I've noticed, however, that bodybuilders who want to gain muscle seem to avoid my original advice: To grow muscle, eat more dietary fat, not only on a low-calorie program but even at above-maintenance calories! A typical plateaued "I can't gain weight" bodybuilder, who was eating 4,000 calories a day in protein and carbs, actually lowered the number of calories he'd been eating and gained muscle, not fat, by eating less protein and eating fat!

How was it possible? His body was oxidizing a portion of the protein he was eating into glucose for energy. He wasn't getting fat, but his body had reduced his protein synthesis to make the conversion of protein to glucose more efficient. An anabolic environment in the body is a state in which the correct selection of macronutrients causes growth. Having an anabolic environment doesn't mean eating as many calories as possible and not getting fat. If all it took to build muscle was to drink a protein drink three times a day, we'd all be huge by now.

John Parrillo has always advocated increasing fats, but his choice has been the esoteric medium-chain triglyceride oil (MCT), the "fat-less" fat. How did John convince his clients and customers to consume those dreaded fat calories? He packaged the oil and directed its use as if it were a supplement, not a simple macronutrient. Supplements seem so precise, high-tech, even...druglike. So I use John's trick to make fats more morally acceptable. We no longer eat "fat." We now take our dose of fatty acids.

Suppose I want to recommend some essential fatty acids. I never say, "Eat some salmon or trout every day." I say, "Take six grams of fish oil capsules, two capsules three times a day." Or I say, "You must add one tablespoon of flaxseed oil to every blender drink." My ideal choice for dietary fat would be whole-food sources, like fish, nuts, avocados or olives, as their various trace micronutrients have added benefit; however, I accept the fact that while bodybuilders won't eat fatty foods, they will consume fat "supplements." Most bodybuilders treat fat as a micronutrient, taking in only milligrams a day, not as a major source of energy calories. Yes, you can consume the bare minimum of essential fatty acids in capsule form, whether it be fish oils or the more exotic hemp-seed oils, but a few capsules won't add enough calories to tip the anabolic balance in your favor. You need to have at least 20 percent of your daily calories coming from fats to improve protein synthesis. Remember, there's no research showing that adding prohormones will improve protein synthesis, but there is such research on dietary fats.

To make it easy, I like to recommend splitting your fats into thirds: Of your minimum 20 percent fat calories, about 7 percent should come from saturated fats (all meat, dairy and MCT fats qualify), another 7 percent from essential fatty acids (from vegetable oil sources) and the last 7 percent from monounsaturated fats found in olive oil and macadamia nut oil.

You need to have at least 20 percent of your daily calories coming from fats to improve protein synthesis. Remember, there's no research showing that adding prohormones will improve protein synthesis, but there is such research on dietary fats.

Eat three solid-food meals. Drink three blender protein drinks, and in each one include one tablespoon of MCT oil and one tablespoon of flaxseed oil or use oil capsules.

My top anabolic choice: 20 to 30 percent of your calories coming from dietary fats every day. Eat three solid-food meals. Drink three blender protein drinks, and in each one include one tablespoon of MCT oil and one tablespoon of flaxseed oil or use oil capsules. Make sure you use two tablespoons of olive oil on your salad greens. If you can't stand olive oil (I can't), use macadamia nuts or their oil. And take six fish oil capsules a day. If you do that every day, you'll be getting at least 20 percent of your calories from dietary fats. Your body will improve protein synthesis, and less of the protein you consume will be oxidized as an energy source.
