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”.
Fish oil is most known for its beneficial heart and cardiovascular effects, and continues to top the list of health promoting supplements. Fish oil is unique in its ability to protect against heart disease and promote cardiovascular health in all people, regardless of age or baseline health status [1, 2]. Fish oil improves the blood lipid profile and is especially effective at lowering triglycerides (a.k.a. blood fats). It also has beneficial effects on blood platelet activity, blood thickness, as well as blood vessel (endothelial) function [4-11], blood vessel elasticity , and blood pressure [13, 14], among other things.
In 2004 FDA approved a prescription fish oil preparation for treatment of high triglycerides (hypertriglyceridemia) [3, 15, 16]. Accumulating research shows that fish oil also has other beneficial effects, which are more visually notable… notably, 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.
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.”
There’s various ways to figure out your cals and macro nutrients, most of them far more complicated then is needed. Here I give a simple way figure figure out both, and remove the mystery of macronutrient ratios that will work well for most of the people most of the time. I tried to get all ‘high art’ and film noir with the effects in this vid, and well, I probably won’t do it again! Sorry, wanted to play with some of the effects the software has I have not tried.
“Knowledge is power” – Sir Francis Bacon
By Will Brink
The above title is one of the best-known expressions in the English language. It was true when it was penned by philosopher Sir Francis Bacon in 1597, and it’s true to this very day… It applies well to the issues of nutrition, supplements, and training, be it to gain muscle mass and strength, or to lose fat.
Can one make progress in their respective goals (e.g., losing bodyfat, gaining muscle mass, increasing strength, etc.) knowing essentially nothing about training, nutrition, or supplements? Maybe….If you do make any progress, it will be slow, hit or miss at best, and often the progress comes in spite of what you did, not because of it! Clearly, a base level of knowledge of a given topic – in this case nutrition, training, and supplements – is essential to obtaining one’s goals. Conversely, does this mean you need to be a rocket surgeon to make steady progress in losing fat or gaining strength and muscle mass? Of course not! As I said in my article on the K.I.S.S principle for making progress (1) :
