Reducing Body Volume: Difference Between Fat and Fluids

How can you tell if an increase in body volume is due to fat or fluid retention, and what can you do to effectively reduce it? We often confuse localized fat with fluid retention. Identifying the cause is key to choosing the most effective treatments and habits to reduce body volume and feel better. Discover how to differentiate between them and what options you have.

Reducing volume is a common goal, but we don't always know if the problem is fat or fluid retention. In this article, I explain how to differentiate them, what causes them, and which treatments and products can help you. You will also discover practical tips and simple habits to feel lighter and improve your day-to-day well-being.

Expert opinion: Reducing body volume is a frequent concern in our consultations. It is essential to distinguish between fat accumulation and fluid retention, as each case requires a different approach. While fat responds better to changes in diet and exercise, fluid retention usually improves with treatments like pressotherapy and lifestyle adjustments. A proper diagnosis and the combination of healthy habits with professional treatments usually offer the best results. The key lies in personalization and professional guidance for every individual.

What differentiates fat from fluid retention?

When it comes to reducing measurements, it is essential to know if the increase in volume is due to localized fat or fluid retention (edema). Although they are sometimes confused, there are clear signs to distinguish them.

Signs of localized fat

• Gradual and persistent increase in body volume
• Area is firmer to the touch
• Does not vary much from one day to the next
• Usually accumulates in the abdomen, hips, thighs, or arms

Symptoms of fluid retention

• Sudden swelling, especially in the legs, ankles, abdomen, or hands
• Rapid weight fluctuations (from one day to the next)
• Feeling of heaviness or tired legs
• When the skin is pressed, a mark may remain for a few seconds

A few months ago, Laura noticed that her ankles were swelling at the end of the day, especially in the heat. At first, she thought she was gaining weight, but upon noticing that the swelling disappeared in the morning, she realized it was fluid retention. She changed some habits and, together with a pressotherapy treatment, she soon felt lighter and more comfortable.

What causes fluid retention?

Edema can appear for different reasons. Identifying the cause helps in choosing the best strategy to reduce swelling.

• High salt intake
• Lack of physical activity
• Ambient heat or temperature changes
• Hormonal changes (menstruation, pregnancy, menopause)
• Blood pressure medications or certain antidepressants
• Circulatory or lymphatic problems
• Insufficient hydration

Practical tips to prevent retention:

1. Drink 1.5–2 liters of water a day
2. Reduce added salt (less than 5g/day)
3. Walk at least 30 minutes a day
4. Elevate your legs when resting
5. Add draining foods like pineapple, cucumber, or asparagus
