Risk factors and chronic diseases often get more attention among the middle-age and elderly population. And rightly so, since that’s when the manifestations of chronic diseases start to show up, and when people get reminded about their chronological age. An integral component of successful aging (also known as healthy aging) is the freedom of physical disabilities and debilitating chronic diseases 1-3. While it is true that it is never too late to become health conscious and reap the benefits of a healthy lifestyle 4,5, the fact remains that the sooner we start the better off we will be as we get older. If you are in your 20s or 30s, or have kids, read on…
Three square meals a day…breakfast, lunch and dinner. Can a person achieve great muscle-building results with just three meals a day?
Absolutely…and I’ll tell you how.
In discussions about dieting, a topic that often comes up is that of “cheating”; is it good or bad to cheat once in a while during a diet?
In order to answer this questions appropriately, it is necessary to look at both the quantitative and qualitative aspects of dieting, and the physiological and psychological responses they each elicit.
My objective science response to this is “I told you so!”
But seriously, this is a very important study, I have said something similar for decades. For example, if you read my article Brink’s Unified Theory Of Nutrition you will see I essentially concluded what this recent study found: Not all calories are created equal, macro nutrient ratios matter, and there’s profound effects from simple changes in those macro nutrient ratios on body comp, and tracking changes in fat vs. weight is what actually matters… I don’t know if this study will get the attention it deserves in the media, or by the main stream nutrition/med community, but it’s a seminal study. The fact is, older studies that simply track weight loss/gain need to be scrapped as they are essentially of no value in my view. Modern studies such as this, that actually look at end points that matter, are what will finally answer age old questions on nutrition.
Below is write up of the study for non-science types, and a link to the full study follows for those who wish to read that too.
Calories Raise Body Fat When People Overeat, Not Protein
Medical News Today
In a study published in the January 4 issue of JAMA, researchers assessed 25 healthy individuals who were randomized to different levels of overconsumption on protein diets whilst living in a controlled setting. They found that those who consumed the low-protein diet gained less weight compared with those eating normal and high protein diets. Furthermore, they established that calories alone and not protein seemed to contribute to increases in body fat and that protein did contribute to changes in energy expenditure and lean body mass.
According to background information in the article, “Obesity has become a major public health concern with more than 60 percent of adults in the United States categorized as overweight and more than 30 percent as obese.” However, which role the composition of a diet plays in response to overeating and energy dissipation remains unclear.
Mitochondria are the ‘energy powerhouse of the cell’ that convert the foods we eat to usable energy our body uses to fuel life sustaining reactions within cells, our daily activities and athletic performance 1-4. While energy production capability and muscle performance might seem to be more relevant to sports, it also equally important for achievement and maintenance of health throughout the life span. In this article I will describe how chronological aging affects our mitochondria, its implications and the ins-and-outs of a new type of supplements marketed at “exercise mimetics”.
Most supplements are used for one specific outcome, for example fat loss, muscle growth or general health promotion. However, there are a few exceptions. Fish oil is one of them.
We all know about the cardiovascular health benefits of fish oil, and in a previous article I covered the fat loss effect of fish oil. Now let’s take a look at the potential application of fish oil for those of us who are interested in muscle growth…

Fish oil is well known for its beneficial cardiovascular and cardiac health effects. In 2004 FDA approved a prescription fish oil preparation for treatment of high blood triglycerides (hypertriglyceridemia) 1. However, recently several studies have shown that fish oil also has other beneficial effects, which might appeal more to the younger population, and especially to fitness and bodybuilding enthusiasts. One of these effects is fat loss.

Everybody wants to stay young and vital throughout life. But aging is topic surrounded by many questions and myths; here we’ll get to the bottom of it.
Different types of Aging – Chronological Aging and Physiological Aging
Before we get started, I want to make a distinction of two types of aging; chronological and physiological (or biological).
Physiological age, also called biological age, is the result of many factors, many of which are under your control, and varies from person to person (even if they were born on the same date). It refers to age in terms of physical capacity.
Chronological aging refers to how long you have been alive, and is determined by a mathematical formula that is the same for everybody: current date minus date of birth. It is a function of time and cannot be slowed, stopped or accelerated (a side note: according to Einstein’s Theory of Relativity, chronological can be modified, since as one approaches the speed of light, time slows down, and thus so does chronological age. But this isn’t relevant for us earthbound folks).
Physiological aging, on the other hand, describes the state of your body. What’s interesting with physiological aging is that many of the factors that impact it are under your full control (e.g. exercise, nutrition, sleep etc). While chronological and physiological aging are related, the years of your life doesn’t necessarily have much to do with the years of your body. Many people don’t like to tell their (chronological) age; however, if you have taken care of yourself you should be proud of it!
Thus, chronological age and physiologic age do not always coincide, and physical appearance and health status often do not always correspond to what is typical at a particular chronological age. When talking about aging and anti-aging, it is the physiological age we’re referring to. Ok, now that we got that cleared out, let’s move on.
To most people outside the gym, the word “muscles” brings to mind huge bulging muscle bellies and bodybuilders. The importance of muscle mass, strength, and metabolic function in the performance of exercise and sports, has never been questioned. However, muscles aren’t just for show. Here I will explain why.
The Institutes Of Medicine – commissioned by The DOD – just put out a paper I found very interesting looking at the impact of Nutrition and Traumatic Brain Injury TBI). The paper was called:
The report outlines key nutritional interventions that may be of value to TBI. What I found particularly interesting was the identification of creatine (among others) as a possible nutrient of benefit. I have written about creatine as a possible Neurological Protection to brain injury and other insults:
A growing number of studies have found that creatine can protect the brain from neurotoxic agents, certain forms of injury and other insults.
Several in vitro studies found that neurons exposed to either glutamate or beta-amyloid (both highly toxic to neurons and involved in various neurological diseases) were protected when exposed to creatine.3 The researchers hypothesized that,
“… cells supplemented with the precursor creatine make more phosphocreatine (PCr) and create larger energy reserves with consequent neuroprotection against stressors.”
