  • Calorie counting and why it works (sometimes)

    Does calorie counting work? (Getty Images)

    The "advice" given to overweight people by most health care providers is to eat less, count your calories and eat below your maintenance requirements.

    This method has many flaws, including difficult adherence, lowered metabolism, loss of lean muscle, and possible nutritional deficiencies if you care more about cutting calories than you do about eating enough nutritious food.

    Most glaring of all is that it doesn't work for many people. Despite the restrictive lifestyle they put themselves on, they don't seem to get much resultThis is backed up by research* showing that the effectiveness of a diet plan was VERY dependent on the current state of the individual person.

    The main difference in question was what is known as insulin resistance.

    Simply put, a person who is insulin resistant tends to put any nutrients eaten into their fat stores  i.e. they get fatter. A person who is insulin sensitive (the opposite of resistant) tends to put their nutrients into muscles and organs for use

  • Why you can’t ‘burn off’ a bad meal

    The method of guilt-based exercise doesn't work to burn off calories eaten. (Getty Images)

    One of the common misconceptions of new clients at Genesis Gym is that they can "burn off" a bad meal by doing some exercise after.

    This is an idea driven by the negative emotion of guilt.

    In this article I will explain why this method of guilt-based exercise doesn't work, and how to plan a "less healthy" meal into your week.

    First let's take what I call the "pizza" example.

    Let's say you go to a party the night before and overdo the pizza eating. According to Domino's website, half a regular peperoni pizza (4 slices) is 1160 calories.

    This has: 135g carbohydrates and 51g fat.

    Then guilt kicks in and you decide to go for a jog. "That will burn it off" you think. So you take a 100 minute jog which is way more than normal, but the thought of that pizza sticking on your love handles helps you push through the sore knees to finish the jog.

    "Phew, I got rid of those 1160 calories!" you might think.

    Not so fast.

    Here is why this method will not work

    1. Food is not just calories, food is

  • 5 tips to boost testosterone

    How can Singaporean men build up their testosterone levels? (Getty Images)

    It was recently reported that Singapore men have falling testosterone levels. This problem is nothing new, and I suspect it will only get worse because our lifestyle and environment encourage low testosterone levels.

    Even the "normal" ranges shown by laboratory tests are, in my opinion, too low for optimal health. Many of these standards in different countries have been lowered to adjust to the new average amounts in people today. Lowered averages doesn't mean that lowered results are normal!

    More on this topic can be found in an excellent book on testosterone by Nelson Vergel called "Testosterone: A Man's Guide".

    In my experience, unless you are a very focused healthy lifestyle person, or on anabolic steroids, your current levels are probably too low! Here are 5 things you can do to improve them naturally. While it's not an exhaustive list, these are simple lifestyle changes that can make a difference.

    1. Stop being a fatty!

    Fat is not simply a place where you store excess food that
