Cardio vs weight training: Which is healthier? Which burns fat more efficient? (Part 13)

Fats! fats! fats! Everyone is trying to avoid this macronutrient! Villain? Or friend? You must be wondering, how could dietary fats play an important role in physical transformation or building a healthy strong body. Most non- pro bodybuilders or athletics and even fitness enthusiasts neglect this macronutrient and usually think protein or carbohydrates as the only or mainly crucial nutrient for building muscles. 

Right now, I'm about to share with you how important dietary fats are to repair and growth. In fact, I can tell you that healthy fats are arguably the most beneficial macronutrients comparing protein and carbohydrates. Fatty acids have a profound affect on muscle gain and fat loss. Sounds ridiculous? Well, keep reading and you will be surprise how beneficial is this macronutrient. I did wrote about Omega 3 fatty acids and fatty acids(saturated fats) in my cholesterol posts earlier. You might be stunned, after finished reading this post, on how a labeled 'villain', could turn out to be something so beneficial for body transformation.

Do you know that fat is the building block of all cell membranes? It is the precursor for all steroid hormones and some neurotransmittors. Yes, same goes to cholesterol being the precursor for steroidal hormones. Most importantly, certain fatty acids can generate a hormone like effect on the body, regulating anabolic and catabolic actions. I will discuss about how essential fatty acids can affects anabolic actions, good and bad fats, and certain foods for muscles and enhancement of sex functions.

Whether one gains or wastes muscles, it depends on the pro-inflammatory and anti-inflammatory actions of EFAs. Dietary fat composition can affect the directions of many metabolic actions, including muscle gain and fat loss.

Good fats heal, bad fats kill. Because of our uncertainty and fear of death, we perceive fats as bad, and many of us have developed obsessive fat phobias, and thus, attempt to avoid eating fat-rich foods. Low fat yogurt, low fat milk, non fat cheese, low fat snacks, etc. We have been going after low fat food products, yet, why do we get fatter and sicker? It doesn't make any sense at all. We are having an epidemic of obesity. Think folks!

In my earlier cholesterol posts, I explain and mentioned that more and more people are afraid of eating food with fats and cholesterol, but heart disease rates are increasing year after year. This is plain silly yet nonsense. Life is not a disease, and human beings need not approach their diet life as crisis management.

Although meats and cheese are regarded as fattening and harmful, these same foods are regarded as great strength builders. Spartans and  ancient Greeks considered meat to be warrior food. Anthropologists have suggested that the human body hasn't changed much since the Stone Age. There is evidence that modern humans are still biologically designed to benefit from hunter gatherer diet, naturally rich in high fat foods. Nuts, meats, eggs, dairy have traditionally been regarded as vigor and potency enhancing foods. On the other hand, the meatless vegan diet has earned the reputation of being the 'healthy' but not a 'sexy' diet. The truth is that, there are distinct dietary factors that affect sexuality regardless of whether one of a meat eater or vegan.

In the body, fat plays a complex role that involves the ability to generate energy, cope with stress and better survive. The ability to endure stress and hardship has kept humans alive during difficult conditions that involve physical threats, danger and famine. This survival mechanism is partially regulated by the actions of oil components called essential fatty acids. Essential fatty acids are the most functional  fats in the body, regulating numerous metabolic actions  that keep us alive.

To deliver their actions, EFAs must first convert into their active derivatives called prostaglandins. EFAs produced both pro-inflammatory and anti-inflammatory prostaglandins. There are so called 'good' and 'bad' prostaglandins.

Ironically, it is the allegedly bad prostaglandins that are immediately involved in our first reactions to stress. The pro-inflammatory prostaglandins help protect the body from physical stress and potential injury by activating a swift immune response and establishing an instant growth stimulation for tissue repair and recuperation.

Now, let's talk abit about anti-inflammatory drugs. We have learned that adrenal hormones play a critical role in regulating reactions to stress. It is reasonable to assume that there is a strong survival mechanism involving pro-inflammatory growth-stimulating agents that can help the body recuperate from stress related catabolic crises and get even tougher and stronger by building new tissue. This survival related reaction to stress involves all anabolic agents, including steroids, prostaglandins, cytokines, adrenal hormones, cellular factor AMP and growth hormone.

People who take anti-inflammatory drugs or painkillers should be aware that these drugs antagonize this survival mechanism by inhibiting pro-inflammatory prostaglandins and thus significantly suppress growth. Athletes and bodybuilders who take anti-inflammatory drugs and painkillers should be aware of the potential inhibitory effect of these drugs on muscular development.

Before I sign off this post, I would like to share with you guys how Omega 3 fatty acids plays a critical role in maximum performance and other important body functions as well. I've shared out the benefits of Omega 3 in another earlier post, but this is an additional sharing relating to biological functions and performance. Both essential Omega 3 and 6 are considered vital and beneficial. Nevertheless, Omega 3 fatty acids is featured as the current favourite in diet books. Fish oil rich in the Omega 3 fatty acids EPA and DHA is one of the most popular nutritional products sold in health food stores and pharmacies.

Omega 3 is actively involved in critical biological fucntions such as improving cognitive abilities, alleviating pain and inflammation, lowering blood pressure and cholesterol, improving insulin sensitivity, and inhibiting over estrogenic activity, thus supressing tumor formation. Omega 3 and 6 EFAs balance each other's actions. In fact, pro and anti inflammatory prostaglandins help maintain healthy metabolic processes that involve an immediate inflammatory response to stress, such as during exercise, followed by an anti-inflammatory secondary response that reduces inflammation and facilitates final recuperation processes that include tissue repair and muscle development.

Once in balance, dietary EFAs are likely to grant a healthy and vibrant metabolism. However, an imbalance or deficiency of EFAs can lead to chronic over-expression of one EFA over another. Dietary EFA imbalance can cause chronic over activity of either pro or anti inflammatory prostaglandins, an adverse and potentially destructive condition that may lead to chronic disease or an overall metabolic breakdown. Please bear in mind that excess of Omega 6 fatty acids is known for promoting excess of estrogen, metabolic disorders, and cancer in animals and human too.

In the next post, I will discuss about how to build muscles with superior biological capabilities. It will be a long post, hopefully I could fit it all in one post, else, I will wrap it up in the double/final post of this whole cardio/weight training topic. I wish to share with you guys on how insulin-like growth factors and growth hormone play a crucial role in body transformation and building muscles, but maybe next time in a different post. Stay tuned..
