Losing the Right Weight with Weight Loss Treatments: Body Composition Explained

Posted on 25th December 2025 by Dr Rekha Tailor

When most people say, “I want to lose weight,” they’re thinking about fat. But the truth is, weight loss can come from fat, muscle, or water. It is very important not to loose muscle since this would slow metabolism and make you weaker and also have long term health implications.

At Health & Aesthetics, we focus on helping you lose the right type of weight – fat – while preserving muscle and hydration. Here’s why that matters and how we do it.

Why Body Composition Matters More Than the Scale

Your bathroom scale only tells you one thing: your total weight. It doesn’t tell you if that weight is fat, muscle, or water. Two people can weigh the same but look completely different because one has more muscle and less fat. Therefore body composition analysis – which shows the amount of fat, muscle and water – is the real measure of health and progress. When weight is lost without monitoring body composition, there is a risk of losing muscle instead of fat. This is the common result following unsupervised weight loss and crash diets. At Health & Aesthetics, we take steps to ensure that doesn’t happen.

How Do Weight Loss Treatments Work

Weight loss treatments are prescription medications designed to help manage appetite and curb cravings. This makes it easier to stick to a calorie controlled diet without constantly feeling hungry. They are very effective when combined with a sensible healthy diet, regular exercise and frequent monitoring.

The Objective: Shedding Fat, Preserving Muscle

The key principle is this: lose fat, retain muscle. This is important because muscle continues to burn calories, even when you’re not active. This is called resting metabolism. If you lose muscle, your metabolism slows, making it more difficult to keep the weight off in the long run. To preserve muscle, avoid crash diets which cut calories and therefore results in loss of muscle. Instead follow these general principles:

  • Eat sufficient protein as this is the vital component of muscle and helps maintain it.
  • Perform regular resistance exercise as this helps to preserve muscle.
  • Seek professional advice. A physician can customise your approach to suit your individual physiology.

Typical Body Composition Ranges

Here’s a brief overview of healthy body composition percentages for both genders:

Component Men (Typical Range) Women (Typical Range)
Body Fat % 10–20% 18–28%
Skeletal Muscle % 40–50% 30–40%
Total Body Water 55–65% 50–60%
Bone Mineral % ~12–15% ~10–12%

Note: These ranges vary by age, fitness level, and health status.

Medical Supervision

It is important that a doctor supervises the treatment. This treatment is quite safe but medical supervision means that –

  • The correct medication and dose is prescribed.
  • Blood pressure, blood sugar, and hydration levels are monitored.
  • Modifications can be made based on individual progress and health

At Health & Aesthetics, your well-being is our top priority. Every patient undergoes a comprehensive evaluation before beginning treatment.

How We Monitor Your Progress with InBody 770

This is where technology truly shines. Our InBody 770 Body Composition Analyser offers much more than a basic scale. It provides:

  • Fat Mass compared to Muscle Mass
  • Visceral Fat Level (the harmful fat surrounding your organs)
  • Water Balance (your hydration level)
  • Segmental muscle distribution (arms, legs and trunk)

InBody Report 

Consider the sample report. It dissects your weight, revealing fat, muscle, and water content. It also highlights muscle balance throughout your body. This granular approach allows us to determine if you’re shedding fat while preserving muscle—not simply losing “weight.”
