Body Composition Analysis with InBody Test

Why Is Body Composition Assessment Important?

Simply focusing on weight loss or gain can be a reductive formula—two people of the same sex and body weight could have completely different body compositions.

Measuring your body composition will help you identify the right areas to work on to improve your overall health and wellness.

At Prologue Centre for Women’s Wellness, we use the InBody 770 to accurately measure your body composition, giving us the insights needed to create a treatment plan tailored just for you.

How Can BMI Be Inaccurate and Misleading?

Despite the popular use of Body Mass Index (BMI) in clinical practice, it is a poor tracking tool for weight change—there’s no way to find out if changes in your weight are in fat or muscle by BMI alone.

On the other hand, a body composition assessment can tell you how much of your overall weight loss is due to either water, fat, or muscle loss.

Whatever your goals may be, an important thing to remember during your health journey is that there’s more to being healthy than looking thin.

Different Types of Body Composition

We typically fall into one of four different body composition categories below. Getting a body composition analysis helps you design an efficient fitness and nutrition plan.

1

Balanced body composition:

Weight, body fat percentage, and muscle mass are proportionate. Health depends on body fat percentage.

2

High body fat, low muscle mass:

Weight may appear normal, but high body fat and low muscle mass indicate poor composition

3

High muscle mass, low body fat:

Weight may seem high due to muscle mass, but body fat percentage is low, indicating a healthy, athletic build.

4

Low muscle mass, low body fat:

Both muscle and fat are minimal, which may indicate poor overall strength or nutrition.

Benefits of a Body Composition Analysis

A healthy body composition encourages a stronger immune system and reduces your risk of common chronic conditions like high blood pressure and cardiovascular disease.

Here’s how a body composition analysis can improve your wellbeing:

1

Know your baseline:

Understand what you need to lose, gain, or maintain.

2

Focus on fat, not just weight:

Track your body fat percentage to prioritise fat loss over weight loss.

3

Optimise your workouts:

Tailor your exercise routine to match your unique health and fitness goals.

4

Plan your nutrition:

Calculate your calorie needs to create a diet that works.

5

Set realistic goals:

Track your progress accurately and stay motivated with achievable milestones.

6

Understand weight changes:

Identify whether your weight fluctuations are due to fat loss, muscle gain, or other factors.

A body composition assessment can help you take control of your fitness journey with more thoughtful insights.

How to read your InBody 770 report

Chapter 1: Body Water & Body Composition

This section gives an overview of your weight, muscle, fat, and water balance.

A) Weight

  • Your total body weight—used as a starting point for interpreting all other data.
  • Not very meaningful on its own, but useful when paired with fat and muscle measurements.

B) Total Body Water (TBW)

  • Shows how much water is in your body.
  • Split into:
    • ICW (inside cells): Good sign of cell function & hydration
    • ECW (outside cells): If this is too high, it might point to inflammation, water retention or recovery needs

C) Dry Lean Mass (DLM)

  • Your muscles and bones (without water).
  • An increase = likely muscle gain, especially if you’re training or eating well.

D) Lean Body Mass (LBM)

  • Everything in your body except fat (muscles, bones, water, organs).
  • A higher LBM often means more muscle—but it can also rise if you’re retaining water (e.g. after hard training).

E) Body Fat Mass (BFM)

  • The amount of fat in your body.
  • Tracking this alongside LBM helps you see if you’re losing fat, gaining muscle, or both.

F) ECW/TBW Ratio

  • Shows how balanced your fluid levels are.
  • Slight changes are normal, but consistently high values may suggest inflammation or stress.
  • Best interpreted over time, especially with regular training.

Chapter 2: Muscle, Fat & Obesity Risk

Muscle-Fat Analysis (C-I-D Shape)

  • This section compares your weight, muscle, and fat levels to healthy averages.
  • The bar graph forms a shape to represent your current state:

Body Shape Classification

Shape
What it Means
C-shape
Higher fat, lower muscle – goal: lose fat, gain muscle
I-shape
Balanced – maintain or refine composition
D-shape
More muscle, less fat – often seen in athletic builds

Body Composition Analysis Methods

  • Skeletal Muscle Mass (SMM): The muscle you can build with exercise
  • Body Fat Mass: Total amount of fat stored in your body

Obesity Analysis

  • BMI: General measure using height and weight—not always accurate
  • Body Fat % (PBF): A better indicator of fat levels and health risks
  • Focus on lowering PBF, not just the number on the scale

     

Body Composition History

  • Tracks changes in weight, muscle, fat, and water balance over time
  • Look for:
    • Muscle up + fat down = great progress
    • Weight down but muscle down too = time to focus on strength or nutrition

Chapter 3: Segmental Lean Analysis (Muscle in Body Parts)

Breaks down muscle mass in:

  • Left/Right Arms
  • Left/Right Legs
  • Trunk (core & back)

Why it matters:

  • Helps you spot muscle imbalances or underdeveloped areas
  • Guides training to correct imbalances and improve strength evenly

Chapter 4: Custom Outputs – Your Personalised Insights

A) Body Fat & Muscle Recommendations

  • Suggests how much fat to lose and muscle to gain for a healthier composition
  • Great for setting realistic fitness goals

B) Segmental Fat Analysis

  • Measures fat in different body parts (e.g. arms, legs, trunk)
  • Helps track where you’re losing fat over time
  • You can’t spot-reduce fat, but this helps keep you motivated

C) Basal Metabolic Rate (BMR)

  • The number of calories your body burns at rest
  • Helps plan how much to eat
  • Your actual calorie needs are higher, as BMR doesn’t include activity

D) Visceral Fat Area

  • Visceral fat = fat stored around your organs
  • High levels = higher risk of chronic conditions like diabetes & heart disease
  • Cardio and healthy eating help reduce this

FAQ

Who is at risk for unbalanced lean body mass?

Certain groups, such as sedentary adults, “skinny fat” individuals (sarcopenic obese), and the elderly, are more likely to have muscle imbalances, often with weaker lower body muscles compared to the upper body.

“Skinny fat” refers to individuals who appear slim but have a high body fat percentage and low muscle mass, putting them at risk for health issues like metabolic disorders.

Balanced muscle development supports proper posture, reduces injury risk, and improves overall strength and mobility.

It’s recommended to assess your body composition every 1-3 months to track progress and adjust your fitness or nutrition plan as needed.

Of course. It can help you focus on losing fat while preserving or building muscle, ensuring healthier and more sustainable weight loss.

BMI can still provide a helpful general reference, but it’s less thorough than body composition measurements.

Subcutaneous fat lies under the skin, while visceral fat surrounds organs and presents a higher risk for conditions like heart disease and diabetes.

Of course. It can help you focus on losing fat while preserving or building muscle, ensuring healthier and more sustainable weight loss.

Hydration levels affect measurements like bioelectrical impedance, so staying properly hydrated ensures more accurate results.

Yes, older adults can improve muscle mass and reduce fat through resistance exercises and a protein-rich diet tailored to their needs.

After a few sessions, my DR gap improved and i also noticed less bloating. I can fit into my clothes better too.

Amanda Lim

Jodie has been such a great help in my health journey! She really took the time to help me understand my body and gave super practical tips that actually fit into my daily routine. I learned so much about portion control, and I love how she explained how nutrition and exercise can be adjusted around the menstrual cycle — it made everything click for me. She’s knowledgeable, approachable, and easy to talk to. I feel a lot more confident now about making choices that work for me. Highly recommend her!

Prologue Wellness takes a truly holistic approach to weight management and well-being. Instead of quick fixes, they focus on educating clients about proper nutrition, helping us build sustainable habits that improve both health and quality of life.

I also love their Clinical Core & Flow programme, which combines physiotherapy, Pilates, and yoga. It creates a supportive environment for women of all fitness levels.

On top of that, they offer innovative non-invasive treatments like Exion Body, Vanquish Me, and EmBody. These complement their holistic programmes perfectly by supporting body contouring, fat reduction, and muscle strengthening in a safe, effective way.

The team, especially Jodie, Shonia and Serene, are professional, caring, and genuinely invested in their clients’ well-being. Highly recommended if you’re looking for a place that integrates science, movement, and holistic care.

Samantha Lim

The staff’s warmth, support, and use of technology have helped me improve my postpartum core muscles and pelvic floor health

Jean Toh

The struggles of postpartum recovery are real, and I’m so thankful to have found Prologue, a women’s wellness centre that truly understands and supports mothers like me.

Like many postpartum mums, I’ve been dealing with diastasis recti, a bulging tummy that makes me look pregnant, urinary incontinence that limits my activity with my kids, and difficulty losing pregnancy weight due to stress eating and late nights.

Since starting my personalised treatment plan here, I’ve seen real improvements. Weekly sessions with my nutritionist, Jodie, have helped me eat in a balanced and sustainable way. Physiotherapy sessions with Chloe and Jodie have strengthened my core and pelvic floor, while the Emsella chair has improved my incontinence. Embody treatments are helping with my DR, shockwave therapy is reducing bloating and stretch marks, and Exion Body treatments are tightening loose skin.

I’m truly grateful for the professional, encouraging, and caring team at Prologue who have supported me every step of the way. Highly recommended to any postpartum mother looking to recover, rebuild, and regain confidence.

Would highly highly recommend this place to postpartum ladies. Other than the many machine services to help with various issues such as DR, weak pelvic floor muscles and loose skin, they also have trained nutritionist and physiotherapist to help provide a holistic recovery experience! Truly glad that Proloque team has helped to resolved my DR and I have seen improvements in my core and pelvic floor muscles! Lastly, the space here is nicely done up and the team of ladies here are very friendly and professional.
