What Is Metabolism?

The word metabolism is thrown around so loosely and often when speaking about body fat and weight loss. What does ‘metabolism’ really mean, and what does it do to your body?

  1. Metabolism is a collection of chemical reactions that takes place in the body's cells.
  2. Metabolism converts the fuel in the food we eat into the energy needed to power everything we do, from moving to thinking to growing.
  3. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions. In fact, thousands of metabolic reactions happen at the same time — all regulated by the body — to keep our cells healthy and working.


By looking at the photo above, you can see that 2kg of muscle (pictured on the bottom) is going to take up less space in the body and be a lot less “lumpy” under your skin and in between your organs than the same weight in fat (shown on top).

Muscle and fat differ in density and one kilo of muscle occupies less space (volume) than one kilo of fat.

Besides being more compact in the body, there are also many health advantages to increased muscle mass.

Benefits of having more lean muscle mass:

  1. Create a leaner physique-
  2. Reduce your risk of injury
  3. Increase strength, stability, power and endurance
  4. Improve balance and mobility
  5. Improve the way you feel about yourself
  6. Increase energy and vitality
  7. Improve athletic performance
  8. Increase your metabolic efficiency
  9. Improve insulin sensitivity and improve blood glucose control

Increase your metabolism

Each 1kg of fat that your body stores represents 1,540 calories of unused energy. In order to lose 1kg you have to create a calorie deficit of 1,540 calories by either consuming 1,540 less calories over a period of time than your body needs or by doing 1,540 calories worth of exercise.

By increasing your lean muscle mass through resistance and body weight training, you will help your body burn more calories. One kilo of muscle will burn slightly more calories at rest than one kilo of fat tissue at rest. Also it will balance out insulin sensitivity and blood glucose levels which ensures you have a greater chance of losing body fat. When your blood sugar is out of whack it increases your chance of storing body fat.

Danielle Smith

Danielle Smith is the Founder of Glow For Life, with personal experience acting as the driving force for her passion to make a positive difference to the health and wellness of others.

Danielle tipped the scales at 30kg overweight in her childhood years and was a constant target for bullying. After making the decision to lose weight, Danielle moved to the opposite end of the spectrum, battling anorexia and bulimia for several years. Due to these early issues in her childhood she suffered from health issues later on in life like IBS, an underactive thyroid, nutrient deficiencies which lead to fatigue where she has spent countless hours and dollars with doctors, naturopaths and numerous allied health professionals trying to identify what was wrong.

After a lengthy recovery process, Danielle was able to build a healthy relationship with food, exercise and body image and made this a core priority in her life.

Unfortunately, a corporate career path with no passion or personal motivation caused Danielle’s priorities to slip, with health, fitness and attitude to life all taking a back seat.

The ‘Glow moment’ that Danielle had was a telephone call informing her that her mother was going to die. She was sick with jaundice, had a tracheotomy in her throat, was on a dialysis machine and her body was not receiving the nutrients required. The next day her father was admitted to hospital with renal failure.

Having experienced first-hand what can happen when you don’t prioritise health and wellness, Danielle knew it was her purpose to help educate and assist people to make positive changes in their lives to ensure that they are the ultimate version of themselves.

This was the catalyst for Danielle to quit her corporate career, study fulltime and begin her “Glow for Life” journey.

Since taking the plunge, Danielle has worked as a Personal Trainer at Soultrain in Woolloomooloo and as a Sport Massage therapist for the GWS Giants and worked with Julia Russell Massage therapy with such sports teams like The NSW Waratahs, South Sydney Rabbitohs, West Tigers and the NSW Cricket team.  She has just recently returned from spending time in New York training with some of the elite trainers at Equinox Greenwich in Manhattan and Celebrity Trainer from Muscle Manhattan, as well as training in Thailand at a Muay Thai training camp,  with current Muay Thai champion fighters.

Danielle is currently working with individuals, couples and families as well as in the corporate space, promoting health and wellness in the workplace and in general life.
