Many of us reach a point where diet and exercise alone don’t shift stubborn fat — especially around the hips, thighs, and lower abdomen. INFRASLIMX offers a smarter, low-impact solution by combining infrared heat, vacuum resistance, and gentle cycling into one powerful session.
This next-generation weight loss therapy improves circulation, raises tissue temperature, and supports lymphatic drainage, making your workouts feel easier while helping your body burn energy more efficiently.
Below, we break down the science behind infrared heat therapy for weight loss, what you can expect during a session, and why INFRASLIM has become one of London’s most popular body-shaping treatments.
Looking for weight loss and body shaping in London? INFRASLIMX is available exclusively at Re:nu Optimum Health in Greenwich. Bookings are open for single sessions, packages, and exclusive memberships.

How INFRASLIMX Works – The Science Behind Vacuum and Infrared Weight Loss
Our cutting-edge INFRASLIM London treatment helps to burn fat, reduce cellulite, build muscle, detoxify, and tighten the skin. Here’s a look at the science behind how it works.
Infrared Heat
Non-invasive yet powerful infrared light raises the body’s core temperature to help you burn calories more efficiently. The deep-penetrating wavelengths boost cellular metabolism, stimulate circulation, and dilate blood vessels, accelerating the breakdown of body fat.
Vacuum Resistance
Advanced vacuum technology stimulates the connective tissue, maximising the effect of the infrared light. By applying negative pressure to the body, vacuum resistance encourages blood flow to stubborn fat zones and improves cellular oxygenation, enhancing performance and speeding up fat loss.
Lymphatic Drainage
A secondary effect of vacuum technology is enhanced lymphatic drainage. The gentle pressure stimulates the lymphatic system, flushing out toxins, waste, and excess fluid while reducing cellulite and improving skin elasticity.
Low-Impact Cardio
The INFRASLIM bike requires gentle, reclined cycling, enhanced by vacuum and infrared heat. You can select your ideal settings on the infrared exercise bike, but you don’t need to perform intense cardio – the heat and vacuum features make low-intensity cycling feel more effective without added strain.
How Does INFRASLIMX Work for Weight Loss?
What does all that mean for your weight loss journey? The key benefits of infrared therapy for weight loss include:
- Accelerated fat burning: infrared weight loss treatments help you burn calories faster, and shed fat quicker.
- Improved detoxification: enhanced circulation improves lymphatic function, reducing fluid retention and removing toxins.
- Faster recovery: infrared heat relieves muscle tension to improve post-workout recovery.
- Reduced cellulite: improved lymphatic drainage and circulation can minimise the appearance of cellulite and firm the skin.
- Optimised metabolism: infrared heat boosts your metabolism, helping you function and burn fat more efficiently.
- Enhanced well-being: the INFRASLIM infrared weight loss machine can help balance mood and lower cortisol, which is linked to stubborn fat retention.
INFRASLIMX vs Other Weight Loss Methods
Here’s a quick overview of how it compares to other weight loss options:
| Method |
How It Works |
Evidence for Weight Loss |
Session Time & Effort |
Best For |
| INFRASLIMX |
Infrared heat + vacuum pressure + low-impact cycling increase circulation, heat, and exercise intensity. |
Supports cardio efficiency, faster weight loss, and body shaping. |
20 minutes of gentle–moderate pedalling. |
People wanting comfortable, joint-friendly cardio, enhanced warmth/circulation, and structured fat-loss support. |
| Traditional Cardio |
Increases heart rate, oxygen use, and calorie burn through sustained aerobic movement. |
Strong, long-established evidence for reducing body fat when paired with nutrition changes. |
Session length usually 30–60 minutes, moderate to vigorous effort depending on fitness level. |
Anyone seeking proven metabolic fat loss and improved cardiovascular health. |
| Infrared Sauna / Heat Therapy |
Raises core temperature and increases heart rate + sweat; passive heat exposure. |
Small increase in calorie burn, mostly water-weight changes; minimal direct fat-loss effects. |
10–30 minutes of passive heat exposure. |
Recovery, relaxation, circulation, not primary fat loss. |
| Cryotherapy |
Short exposure to extreme cold may activate brown fat and trigger endorphins. |
Mixed and limited evidence for measurable fat loss; stronger support for recovery and well-being. |
2–3 minutes, often in a multi-session course (10–20+ sessions). No physical effort required. |
People wanting inflammation + recovery benefits, with light metabolic support. |
Remember that sustainable weight loss relies on a balanced, healthy lifestyle of regular exercise and smart nutrition. INFRASLIMX is a stand-out, supplementary therapy that’s comfortable and time-efficient, especially for people who struggle with traditional cardio.

Vacuum and Heat Therapy for Weight Loss – What to Expect at Re:nu London
As with all biohacking treatments at Re:nu Optimum Health, a consultant will guide you through the therapy before your session. Here’s an overview of what you can expect from our infrared weight loss treatment.
Duration
INFRASLIM London sessions at Re:nu last approximately 20 minutes.
What to Wear
Gym clothes and trainers are best to ensure comfortable pedalling.
What it Feels Like
Reclined in a semi-enclosed pod on the reclined INFRASLIM bike, you’ll feel a gentle warming of your thighs, hips, and abdomen as you pedal.
Typical Calorie Burn
Calorie burn varies between clients, but you can expect it to be significantly higher than regular cycling.
Expected After-Effects
Many clients feel lighter, detoxified, and uplifted. You may feel thirsty if not properly hydrated, so drink plenty of water before and after your session.
Real Results From INFRASLIMX at Re:nu London
★ ★ ★ ★ ★
“I got a really good deal on the INFRASLIM package and have found it to be extremely motivating. Everything was beautifully explained to me by Natsumi who walked me through my free health scan results and answered all my questions clearly and patiently. All the staff are very attentive and very thoughtful, Swanzie and Billie have both been very kind and all 3 staff members are very clearly well versed in their knowledge of the treatments and their impact. Even just small details like the free hydrogen water prove that this clinic isn’t only trying to sell you something but they genuinely have a mission of wellbeing and health. Can’t recommend enough.”

How is INFRASLIMX Different From Regular Exercise or an Exercise Bike?
Exercising on an INFRASLIMX infrared vacuum bike enhances the benefits of regular exercise without requiring additional physical exertion. Infrared heat and vacuum technology work together to accelerate calorie burn, helping you lose weight faster than with traditional exercise.
Can I Combine Infrared Heat for Weight Loss with Other Re:nu Treatments?
Absolutely. Several of our advanced therapies can complement the effects of INFRASLIMX:
- Cryotherapy – further boosts the metabolism and helps burn calories faster.
- Compression Therapy – enhances lymphatic drainage for extra detoxification.
- Red Light Therapy – increased red and near-infrared light exposure improves recovery and supports skin health.
How Many Sessions Will I Need and How Long Do Results Last?
The ideal number of sessions depends on your goals. We recommend 2-3 sessions per week to see the best results. Once you notice visible changes, you can reduce your session frequency to maintain the effects.
Our infrared bike in London is designed to support a healthy diet and lifestyle, so if you stop completely or change your habits outside of Re:nu treatments, results are likely to fade.
Can INFRASLIMX Help with Cellulite and Skin Tone as Well as Fat Loss?
Yes, the vacuum resistance technology encourages lymphatic drainage, which helps improve the skin’s elasticity and visibly reduce cellulite.
Where Can I Try INFRASLIMX in London?
INFRASLIMX is available in London exclusively at Re:nu Optimum Health. Visit our state-of-the-art wellness centre in Charlton Riverside, Greenwich, to discuss your weight loss goals and create a personalised wellness plan.
