When it comes to healthy habits, too much of a good thing can backfire, and that applies to exercise as well. While most people suffer from lack of exercise, once you get going, it can be addictive and some people do end up exercising too much — either by exercising too intensely, and/or too frequently.

However, a really important part of creating optimal fitness is recovery. An equation to keep in mind is that as intensity increases, frequency can be diminished…

One of the key health benefits of exercise is that it helps normalize your glucose, insulin, and leptin levels by optimizing insulin/leptin receptor sensitivity. This is perhaps the most important factor for optimizing your overall health and preventing chronic disease.

But exercise affects your body in countless other ways as well—both directly and indirectly. Here, however, even the most unexpected side effects are almost universally beneficial. For example…

If you’re still not doing interval training, you’re likely wasting an awful lot of time in the gym. This is one of the most important developments in fitness science that I can think of, as you can reap far greater health benefits in less time.

But I’ve recently also started talking about the potential health benefits of intermittent fasting and working out in a fasted state (i.e. skipping breakfast before hitting the gym)…

Many exercise systems often sound great at first, but in reality simply will not make a good fit for your life.

Thankfully, there is something else you can try called bodyweight exercising, which is so flexible that it answers every possible concern you might have, including time constraints, prohibitive cost, and location issues.

Bodyweight exercise got its name because your own body provides all the resistance needed to help you get fit…

Loss of muscle mass with age (sarcopenia) may be caused by a reduction of muscle protein synthetic response to food intake. A group of researchers set out to find which milk protein was the best for muscle protein accretion, and would therefore help stave off sarcopenia.

Three groups of older men were fed a meal-like amount of whey, casein, and casein hydrolysate proteins…

Exercise is a key factor of optimal health; it’s particularly important for controlling your blood sugar and normalizing your insulin levels. I often recommend viewing exercise as a drug that needs to be properly prescribed and “taken” at a proper dosage.

When done correctly, exercise can oftentimes act as a substitute for some of the most common drugs used today for things like diabetes, heart disease and depression…

If you’re already off to a good start on a healthy fitness plan, and you’re looking for ways to take it to the next level, then you might want to consider intermittent fasting. In essence this fitness-enhancing strategy looks at the timing of meals, as opposed to those fad plans where you eat just one or two things for several days in a row.

On intermittent fasting, the longest time you’ll ever abstain from food is 36 hours, although 14-18 hours is more common…

If you’re like many people, you may start your day with a cup of coffee. According to Health Magazine,1 about half of American adults stick to this daily ritual, despite conventional warnings that coffee might not be all that good for you.

My own understanding of coffee’s virtues and risks was greatly enhanced by my 2011 interview with Ori Hofmekler, author of The Warrior Diet and Unlocking the Muscle Gene, who has researched coffee extensively…

Dental caries are caused by demineralization of your teeth (enamel and dentin) by the acids formed during the bacterial fermentation of dietary sugars.

Demineralization is countered by the deposit of minerals from your saliva, or remineralization, which is a slow process, and enthusiasts report that fluoride prevents dental caries by enhancing this mineralization…

Spirulina, a type of blue-green algae, is an incredible superfood that provides a concentrated source of protein, vitamins, antioxidants, and other nutrients. As one of the oldest life forms on Earth, the use of spirulina as a food source dates all the way back to 9th century Chad, and it is believed spirulina was used by the Aztecs in 16th-century Mexico.

Spirulina, a type of one-celled organism, got its name from the Latin word for “helix” or “spiral” because of its spring-like physical characteristic…
