How to Get Rid of Body Fat: What Actually Works

Posted on [post_date] [post_comments] [post_edit]

"How do I get rid of fat from my [chest / chin / stomach / thighs]?" is one of the most common questions we hear at consultation, and one of the most commonly answered badly elsewhere. Spot reduction — losing fat from one specific area through exercise or local treatment — is not how human fat metabolism works. Understanding what is actually achievable through lifestyle change, and what requires intervention, is the foundation for any sensible plan.

This guide explains how body fat actually behaves, what works and what does not, and where cosmetic sits in the picture.

The biology of body fat

Body fat is not stored as a single homogeneous reserve. It exists in two distinct categories:

fat sits between the skin and the muscle. This is the fat you can pinch. It accounts for the visible "softness" of body contour — abdomen, hips, thighs, upper arms, chin, chest. It is metabolically less active than fat and is the slowest to mobilise during weight loss.

Subcutaneous fat distribution is largely determined by genetics, sex hormones, and age. Women predominantly accumulate fat on the hips, thighs, and buttocks (a gynoid pattern); men predominantly accumulate it around the abdomen (an android pattern). These patterns are heritable — if your parents store fat in particular areas, you probably will too.

Visceral fat sits inside the abdominal cavity, Rhinoplasty around and between organs. This is the fat that the firm, distended sometimes called a "beer belly" — it pushes out from inside rather than sitting softly on top. Visceral fat is metabolically active, produces inflammatory signalling molecules, and is the fat type most associated with cardiovascular disease, type 2 diabetes, and other metabolic .

Visceral fat responds quickly to weight loss — often disproportionately so, in the first few weeks of a sustained calorie deficit. Subcutaneous fat responds more slowly, and the specific areas it leaves first are determined by your individual pattern, not by which muscle group you exercise.

Why spot reduction doesn’t work

The persistent myth is that exercising a specific muscle group burns the fat sitting on top of it. Crunches will eliminate abdominal fat; tricep dips will eliminate upper arm fat; chest will eliminate chest fat. The biological this assumes — local fat being mobilised by adjacent muscle activity — does not exist.

Fat is mobilised systemically. When you create a calorie deficit, the body releases stored fatty acids into the bloodstream from fat cells throughout the body, and the pattern of release follows your individual distribution. The muscles being exercised use circulating fatty acids as fuel, but they do not preferentially draw from local fat depots.

This has been tested directly. Studies measuring fat loss from exercised vs non-exercised body areas during training programmes show no preferential loss from the exercised area. A person doing 1,000 crunches a day loses fat from wherever their body releases it first — usually not from the abdomen.

What targeted exercise does achieve is muscle development underneath the fat. Larger, more defined underlying muscle produces a more contoured appearance even at the same overall body fat percentage. This is genuinely useful — but it is muscle development, not fat removal.

What actually reduces body fat

The only mechanism that produces fat loss is consuming fewer calories than you expend over months. The specific dietary framework matters less than your ability to maintain the deficit:

The shared feature is sustained calorie deficit. Any that that, sustainably, produces fat loss. Frameworks that produce rapid initial loss but cannot be maintained typically backfire through rebound.

Practical principles regardless of framework:

Exercise alone is a poor weight-loss tool. The calorie cost of activity is lower than most people assume, and exercise often triggers compensatory increased eating that erases the deficit. Exercise alongside change, however, improves the substantially:

For body fat reduction, the practical combination is: 150 minutes per week of moderate-intensity activity, 2–3 resistance training sessions, daily step target of 8,000–10,000, alongside a moderate calorie deficit through diet.

The GLP-1 receptor agonists (semaglutide, marketed as Wegovy for weight loss and for diabetes; tirzepatide marketed as Mounjaro) have substantially changed what is achievable through medication. loss is around 15% of body weight with semaglutide and around 20% with tirzepatide over 12–18 months, alongside diet and exercise.

These medications are appropriate for patients with BMI ≥30, or ≥27 with weight-related health conditions. They are not appropriate as cosmetic weight-loss tools for non-obese patients pursuing aesthetic goals. See for .

Where cosmetic surgery actually fits

Cosmetic surgery is not a weight-loss treatment. typically removes 2–5kg of fat in carefully selected cases. some subcutaneous fat alongside excess skin but is fundamentally a contouring procedure, not a weight-loss procedure.

What surgery is something diet and exercise cannot: targeted contour change in specific areas where stubborn fat persists despite an otherwise good body composition. This because the genetic pattern of fat distribution is real. Some patients can lose to a low body fat percentage and still have specific areas — a lower abdominal pouch, hip "saddlebags", an upper inner thigh deposit, a double chin — that do not respond to further weight loss. These are exactly the patients where surgery is appropriate.

The criteria for being a good candidate:

who don’t meet these criteria are usually better served by addressing the underlying weight first. Liposuction on an above-target body produces a smaller version of a still-overweight shape, which is rarely what patients actually wanted.

Area-specific notes

The first place visceral fat accumulates and one of the first places it leaves with weight loss. Subcutaneous abdominal fat is slower to mobilise. A combination of overall weight loss plus core strengthening (planks, dead bugs, weighted compound movements rather than crunches) builds the underlying muscle while overall fat reduces. For residual lower abdominal fat after good weight loss, or — where there is also skin laxity and/or muscle separation — is appropriate.

Important distinction: true gynaecomastia (glandular tissue) versus pseudogynaecomastia (subcutaneous fat). Glandular tissue feels firm and rubbery the nipple; fat feels soft. The two often coexist. Weight loss alone reduces the fat component but does not touch the glandular component. combines liposuction (for fat) with surgical excision (for glandular tissue), tailored to the individual mix. Chest-specific exercise builds underlying pectoral muscle but does not the visible breast tissue.

Submental (under-chin) fat is a common area of localised stubborn fat that does not respond proportionally to weight loss. Some patients have a "double chin" even at a low overall body fat percentage, because the fat pad in this area is genetically determined. Chin exercises ("mewing", neck stretches, chin presses) have no evidence of effectiveness. For a true localised fat deposit with good skin quality, is effective. Where there is also skin laxity, particularly in older patients, this often combines with or surgery for a better long-term result.

The most genetically determined fat distribution pattern, particularly in women. Even with weight loss, hip and outer thigh fat ("saddlebags") often remains. The realistic options are: (1) accept the genetic pattern, (2) if BMI is appropriate and the pattern is localised, or (3) where there is significant skin laxity ( after major weight loss), excisional procedures like .

Upper arm fat with good skin quality responds well to liposuction. Upper arm fat with skin laxity (typically post-weight-loss or older patients) requires rather than liposuction alone.

What doesn’t work

Booking a consultation

If you have reached a stable weight and have specific areas of stubborn fat that have not responded, a consultation can confirm whether contouring is appropriate. We will give you a direct answer, including a "your overall weight needs to come down first" answer where that is the right one. Call or use the .
