Fat Loss and Muscle Toning in Knightsbridge: Which Treatment Is Right?

Fat, muscle, loose skin or cellulite: what are you trying to change?

Start by naming the concern, because each needs a different tool. Fat reduction thins a soft fat layer, muscle toning builds strength and definition, skin tightening firms mild laxity, and cellulite treatment targets dimpling. Many people have two or three of these at once, which is why assessment comes first.

The most common reason people feel disappointed by body contouring is not that the technology failed. It is that the wrong technology was used for the concern. A muscle stimulation course will not shrink a thick layer of fat, a fat reduction device will not tighten crepey skin, and neither is designed to remove dimpling. The decision table below is the same framework our team uses in consultation at Levirgo in Knightsbridge.

How can I tell whether it is fat, muscle or skin?

A simple pinch, tense and lift check gives a useful first clue. Soft tissue that pinches easily is mostly fat. An area that feels firm when you tighten your muscles but lacks shape points to muscle tone. Skin that wrinkles finely or returns slowly when lifted suggests laxity. A clinician confirms this in person.

You do not need special equipment to get a sense of what is happening, and trying this before a consultation helps you describe your goal clearly. Use a mirror in good light and compare both sides of the body.

1. The pinch test

   Relax completely and gently pinch the area between thumb and forefinger. A thick, soft roll suggests a fat layer that a fat reduction treatment could address.

2. The tense test

   Now tighten the muscles underneath, for example by lifting your head while lying down for the abdomen. If the area becomes firm but still looks flat or undefined, muscle tone and strength are part of the picture.

3. The lift test

   Gently lift a fold of skin and let go. Skin that looks crepey, folds finely or is slow to settle suggests laxity, which fat reduction alone may make more visible.

4. The surface check

   Look at the skin in side lighting while standing. A dimpled, orange-peel or mattress-like pattern is cellulite, which involves the connective bands beneath the skin as well as fat.

5. The honest check

   Ask whether your weight has been stable for several months and whether you are close to where you want to be. If not, the order of treatment usually needs to change.

Which non-surgical fat reduction treatment works best?

Radiofrequency and cryolipolysis both reduce a treated fat layer by a broadly similar amount: about 22% to 24% in radiofrequency trials and 10.3% to 25.5% across 19 cryolipolysis studies. The better choice depends on the area, your tissue, comfort and specific risks, rather than a clear winner on results.

Non-surgical fat reduction works by injuring fat cells so the body clears them over several weeks. The two most studied energy-based approaches do this with heat or cold. Surgical liposuction removes more fat at once but involves anaesthesia and recovery. Prescription-only injectable fat-dissolving treatments also exist for small areas; they are medicines with their own assessment requirements and are not offered at Levirgo.

For a detailed look at how radiofrequency affects fat cells, the biopsy evidence and the results timeline, read our in-depth guide to truSculpt iD radiofrequency fat reduction. At Levirgo, fat reduction is delivered through our fat loss service.

Does muscle stimulation really build muscle?

Yes, the evidence suggests it can. In an MRI study of 22 people, four electromagnetic sessions increased abdominal muscle thickness by 15.4% and reduced fat thickness by 18.6% at two months. A 2023 systematic review of 15 studies reported consistent but modest changes, with high satisfaction and no complications reported.

Muscle stimulation devices trigger strong, involuntary contractions that you could not easily produce by exercising voluntarily. Repeated over a short course, those contractions appear to prompt the same kind of adaptation as resistance training: muscle fibres strengthen and thicken. Two broad technologies are used. Electromagnetic devices induce contractions through a magnetic field, while electrical muscle stimulation devices, such as truSculpt Flex, deliver electrical impulses through pads placed over the muscle groups.

The review is balanced about limitations. The typical protocol was four sessions over two to four weeks, and although all studies with patient-reported outcomes described high satisfaction, two studies reported marginal or no benefit, none reported weight change, and several did not describe their participants in detail. The review covered electromagnetic devices only, so its results do not transfer automatically to electrical stimulation systems.

At Levirgo, muscle toning with truSculpt Flex is delivered as a course of at least four sessions of 15 or 45 minutes, spaced no more than three days apart so the course completes within two weeks, with an optional maintenance session every two months. The best candidates already have a relatively thin fat layer over the muscle, because definition only shows if it is not hidden.

Can non-surgical skin tightening fix loose skin on the body?

Skin tightening can improve mild to moderate laxity by heating the deeper skin layers to stimulate collagen, with gradual change over several weeks and a course of treatments. It cannot remove heavy, overhanging skin after major weight loss or pregnancy, which usually needs a surgical assessment.

Skin firmness depends on collagen and elastin in the dermis. Both decline with age, sun exposure and large changes in weight. Radiofrequency and focused ultrasound devices deliver controlled heat below the surface; the immediate effect is a slight contraction of existing collagen fibres, and the longer-term aim is new collagen formation over the following weeks. That biology explains why results are gradual and why expectations need to be modest.

Levirgo’s skin tightening treatment uses radiofrequency or ultrasound energy chosen for your needs, typically in sessions of 30 to 60 minutes as a course of three to six. For some areas, HIFU, which focuses ultrasound energy at depth, is an option. If fat reduction is also planned, it is worth checking laxity first, because thinning a fat layer under loose skin can make the looseness more noticeable.

Can cellulite be treated without surgery?

Cellulite affects 80% to 90% of women after puberty and is not a medical problem. Treatments can improve its appearance for some people, but a systematic review of 67 studies found no clear evidence of good efficacy for any single treatment. Honest, combined approaches aim for smoother-looking skin, not removal.

Cellulite forms where fibrous bands tether the skin to deeper tissue while fat pushes upwards between them, creating a dimpled surface. Hormones, genetics, skin thickness and fat distribution all play a part, which is why it appears in people of every size and fitness level, and why it is so much more common in women than men.

That finding does not mean nothing helps, but it does mean claims of dramatic or permanent cellulite removal should be treated with caution. The US FDA clearance for the truSculpt system, for example, describes its massage device as intended for a temporary reduction in the appearance of cellulite. Improving the underlying contributors, such as a localised fat bulge, weak muscle tone and skin firmness, is a reasonable strategy, provided expectations are clear.

Levirgo’s cellulite reduction programme combines fat reduction, muscle toning and HIFU skin tightening in a plan tailored to the area, reviewed with photographs so that any change can be judged fairly.

Can you combine fat reduction and muscle toning?

Yes, and sequencing matters. Fat reduction usually comes first, because muscle definition only shows through a thinner fat layer. In a 2022 study of 12 people, one radiofrequency session followed by six muscle stimulation sessions reduced waist circumference by 3.1% and skinfold thickness by up to 14% at one month.

The combined study, carried out at Siriraj Hospital in Bangkok and published in Lasers in Surgery and Medicine, is relevant because it tested the pairing of 2 MHz radiofrequency with electrical multidirectional stimulation, the technologies behind truSculpt iD and truSculpt Flex, in people with an overweight-range BMI of 23.6 to 24.9. The most common side effect was temporary altered skin sensation for two to three hours after muscle stimulation, reported by 5 of 12 participants, with no serious side effects.

1. Assess and measure each area for fat, muscle tone and skin quality, with baseline photographs.
2. Reduce fat first where there is a meaningful layer, then allow the body time to clear the treated cells.
3. Build muscle next with a short, intensive muscle toning course once the fat layer is thinner.
4. Address skin with a tightening course if laxity becomes more visible as contours change.
5. Maintain with stable weight, regular activity and optional maintenance muscle sessions.

Are body contouring treatments safe, and who should avoid them?

Non-surgical body contouring is generally well tolerated, with mostly mild, temporary side effects such as redness, warmth, numbness or muscle soreness. Pregnancy rules out all of these treatments, and implanted electronic devices or metal in the area rule out radiofrequency and muscle stimulation. A medical history always comes first.

Regulation is still catching up with this sector. In August 2025 the Department of Health and Social Care confirmed plans for a licensing scheme for non-surgical cosmetic procedures in England, with treatments grouped into green, amber and red tiers by risk. Until it is in force, check who assesses you, how devices are maintained, whether risks and alternatives are explained, and whether you are offered a cooling-off period, as the NHS advises.

How much do fat loss and muscle toning treatments cost in London?

Indicative London prices are about £900 to £1,600 for a two-session radiofrequency course on one area, £700 to £1,400 for two cryolipolysis sessions, £900 to £1,800 for a six-session muscle toning course, and £1,600 to £3,200 per area for a combined plan. Your price is confirmed in writing after assessment.

The cheapest route is rarely the single treatment with the lowest headline price. It is the plan that targets the right concern, in the right order, with fewer wasted sessions. Ask what is included in any quote: consultation, measurements, review appointments and aftercare. To discuss your own plan, book a body consultation or contact the clinic.
