How to lose thigh fat: why it's stored there, what works, cellulite and lipoedema

Thigh fat is normal

At the same total body fat, women carry more fat on the hips and thighs than men, a pattern set by sex hormones from puberty. In twins, about 80% of the differences in lower-body fat were down to genes.

It isn't the fat doctors worry about most

In studies that follow people over time, more fat on the hips and thighs goes with a lower, not higher, risk of type 2 diabetes and heart disease than fat around the waist. That's an association, not proof.

Sources 4, 5

Inner thigh exercises don't burn it

When adults trained one leg for 12 weeks, fat came off their arms and trunk, not that leg, and across 13 studies training one part of the body didn't take the fat off it.

Sources 6, 7

Lose fat overall, and keep your legs strong

Eat a little less, move more and strength train twice a week. Your thighs change as your overall body fat does, at the NHS's suggested 0.5 to 1 kg a week.

Sources 8, 9, 10

Cellulite is normal

It affects 80 to 90% of women after puberty because of how bands under the skin hold the fat. No exercise, cream or rolling has good evidence for removing it.

Sources 11, 12

Painful legs that bruise easily need a GP

Legs that are painful, bruise easily and are out of proportion with the rest of you may be lipoedema. Swelling and throbbing pain in one leg needs a same-day check for a blood clot.

Sources 13, 14

The fat and the muscles

Thigh fat is the fat under the skin of your hips, bottom and thighs, including the inner thighs and the outer thighs ("saddlebags"). Under it are the quadriceps at the front, the hamstrings at the back and the adductors on the inside; our bigger legs guide covers them.

Sources 15, 16

Sex and hormones

At the same total body fat, women carry more fat under the skin of the hips and thighs than men. The pattern appears at puberty and is shaped by sex hormones. In scans of 234 adults, men carried more of their fat on the upper body and women more on the lower body.

Sources 1, 2

Genes

In Danish twins, about 80% of the differences in lower-body fat were down to genes. Gene studies of up to 224,459 people found 49 regions linked to where fat sits, and most of those that differed by sex acted more strongly in women. Identical twins who were overfed gained fat in the same places as each other.

Sources 3, 17, 18

Age and the menopause

Fat gain speeds up at the start of the menopause transition while muscle falls, and fat tends to move towards the waist rather than the hips and thighs. With age, lower-body fat under the skin tends to fall anyway.

Sources 19, 20, 21

Thigh fat and health

Hip and thigh fat is a long-term store, and in studies that follow people over time it goes with better blood fat and sugar levels than fat around the waist. In Dutch adults aged 50 to 75, women with bigger thighs had lower odds of type 2 diabetes, and in Danish adults, very small thighs went with a higher risk of heart disease and early death. These are associations, not proof, and no reason to want bigger or smaller thighs.

Sources 4, 5, 22

Training one leg doesn't burn the fat on itStrong evidence

In 11 adults who did 960 to 1,200 light leg presses with one leg, 3 times a week for 12 weeks, fat fell 10.2% in the arms and 6.9% in the trunk, but not in either leg. Across 13 studies of 1,158 people, training one limb didn't take more fat off it than off the other.

Sources 6, 7

Why the layer can look thinnerEmerging evidence

In 10 women who trained one leg for 5 weeks, the tissue over the trained thigh got thinner, but the fat cells didn't shrink: the authors put it down to the layer stretching over bigger muscle.

Source 23

Working muscles release a little more nearby fatEmerging evidence

In 10 men doing one-leg knee extensions, the fat next to the working thigh released more fat than the fat next to the resting one. No trial has shown that this adds up to slimmer thighs.

Source 24

Squats and leg presses grow the inner thighsEmerging evidence

Full squats grew the inner thigh muscles 6.2% in 10 weeks in 17 men (half squats 2.7%), leg presses grew the biggest inner thigh muscle 6.2% in 12 weeks, and squats grew the inner thighs more than hip thrusts. The trials were small.

Sources 16, 25, 26

Losing fat overall worksStrong evidence

Each 30 minutes a week of aerobic exercise took off about 0.5 kg in 116 trials. Strength training alone trimmed body fat by about 1.5 percentage points across 54 trials, and in an 8-month trial of 119 adults, aerobic exercise took off more fat while weights added more muscle.

Sources 9, 27, 28

Liposuction doesn't stop fat coming backEmerging evidence

In 32 women randomised to small-volume liposuction or not, body fat was back to the same level as in the other group within a year. The thighs stayed smaller, but the fat returned to the belly.

Source 29

Thigh fat and healthEmerging evidence

Observational studies link more hip and thigh fat with lower diabetes and heart risk, and very small thighs with higher risk. They show associations, not cause and effect.

Sources 4, 5, 22

The menopause moves fat to the waistStrong evidence

In the SWAN study (the Study of Women's Health Across the Nation), the rate of fat gain doubled from the start of the menopause transition until 2 years after the last period, while lean mass fell. In 156 women followed for 4 years, only those who went through the menopause gained deep belly fat.

Sources 19, 20

Eat a little less

The NHS suggests eating and drinking fewer calories than you use and aiming to lose 0.5 to 1 kg (1 to 2 lb) a week. Our calories per day calculator gives a target if your BMI (body mass index) is 25 or more.

Source 8

Move more, low impact if you prefer

Build towards at least 150 minutes a week of moderate activity; in the trials, more minutes took off more. Walking, cycling, the cross-trainer and swimming are gentler on heavy or sore legs than running (our suggestion).

Sources 10, 9

Strength train your legs twice a week

Squats, lunges, step-ups, hip hinges and bridges keep and build the muscle under the fat. Our bigger legs guide's doses: goblet squats at 3 or 4 sets of 8 to 12, lunges at 3 sets of 8 to 12 each leg, and Romanian deadlifts at 3 sets of 8 to 10.

Sources 10, 16

Inner thigh moves are optional

They strengthen the inner thigh muscles, but deep squats and leg presses already grow them, and neither will slim your thighs.

Sources 16, 25

Protein, pace and sleep

About 1.2 to 1.6 g of protein per kg of body weight a day while losing weight (our protein calculator), no crash diets, and 7 to 9 hours' sleep help you keep your leg muscle while the fat comes off.

Sources 30, 31, 32

Around the menopause

Keep up both strength training and aerobic activity as fat gain speeds up; our menopause guide covers the details.

Source 19

Strength in weeks

Leg strength rises in the first few weeks, and in small lab studies thigh muscle growth showed on scans by about weeks 3 to 4.

Sources 33, 34

Fat at the whole-body pace

At 0.5 to 1 kg a week, your thighs change with the rest of you, over months rather than weeks.

Thighs can be slower for some women

Hip and thigh fat is a long-term, less active store, so for some women it may be slower to change than fat elsewhere (our reading of the research). People differ, so compare yourself with your own photos and measurements.

Sources 1, 4

No one can promise a look

Nobody can tell you how your thighs will look, or when. Strong legs, regular activity and a steady, small calorie cut are what you control.

Most women have itStrong evidence

Cellulite, the dimpled look of the skin on the thighs, bottom and hips, affects 80 to 90% of women after puberty, of every size. Men rarely have it.

Sources 12, 11

It's about the bands under the skinEmerging evidence

Fat under the skin sits in pockets held by fibrous bands. In women the bands run straight up to the skin and are fewer, so fat bulges between them; in men they criss-cross and are stronger. In 20 body donors, men's bands took more force to break (about 38 against 23 newtons).

Sources 11, 35, 36

No exercise has been shown to remove itMixed evidence

We found no trial in which exercise alone removed cellulite. In one trial, 45 women did aerobic exercise 6 times over 3 weeks, and those who also had shock wave therapy ended with less severe cellulite than those who only exercised.

Sources 12, 37

Weight loss helps some, not allEmerging evidence

When women lost weight on medically supervised programmes, cellulite improved for most but got worse for some, more often those who started at a lower weight and lost less. The bands stretch when you gain weight but don't shrink when you lose it.

Sources 38, 11

Treatments: weak or early evidenceMixed evidence

Of 67 studies of cellulite treatments, only 19 were randomised and placebo-controlled, and none showed clear evidence of working well. A 2025 review of 24 trials found none definitively established, though shock wave therapy, radiofrequency and an injection showed promise.

Sources 12, 39

Rollers and fascia blasting

Our fascia blasting guide found no independent trials showing the tools fix cellulite, and reports of bruising and injury.

What it is

The NHS describes lipoedema as an abnormal build-up of fat in the legs and sometimes the arms. It's more common in women, usually affects both sides equally, and can make the bottom, thighs and lower legs look out of proportion with the rest of the body.

Source 13

How it differs from ordinary fat

The feet and hands usually aren't affected, the skin can feel soft and cool, and the legs may hurt, feel tender or heavy and bruise easily. The NHS says it isn't caused by being overweight: you can be a healthy weight and still have it.

Source 13

See a GP

Only a doctor can diagnose it. A GP may refer you to a specialist, and the main treatments include healthy eating and exercise, compression, skin care and support. Our lipoedema guide explains what exercise can and can't do.

Why dieting doesn't shift it

As our lipoedema guide explains, lipoedema fat is largely resistant to diet and exercise, so diets that don't change it aren't a personal failing.

• throbbing pain or swelling in one leg (rarely both), usually in the calf or thigh, red, blue or darkened skin around the painful area (harder to see on brown or black skin), or swollen veins: it could be a blood clot, DVT (deep vein thrombosis)
• swelling in one ankle, foot or leg and you don't know why, or swelling that is severe, painful or very sudden
• legs that become swollen, red, hot and painful with flu-like symptoms: it could be a skin infection

See a GP

See a GP if:

• your legs (and sometimes arms) are out of proportion with the rest of your body, feel painful, tender or heavy, and bruise easily: it could be lipoedema
• both legs, ankles or feet are swollen and it hasn't improved after a few days

Excess skin on the inner thighs can increase after big weight loss. See your GP or surgical team if skin folds become sore, red or broken.

In pregnancy

Pregnancy isn't the time to diet. Most women gain 10 to 12.5 kg, partly as fat stored for breastfeeding; our pregnancy guide covers exercise.

When eating or exercise becomes harmful

The NHS lists spending a lot of time worrying about your weight and body shape, eating very little food, exercising too much, and having very strict habits or routines around food among the signs of an eating disorder, and says to see a GP as soon as you can. Beat adds rigid or punishing exercise, exercising to make up for eating, and exercising when ill or injured. Beat's helpline in England is 0808 801 0677, and our eating disorders guide has the other numbers.

"Inner thigh exercises slim your thighs"Strong evidence

Training one leg for 12 weeks took fat off the arms and trunk, not the trained leg, and 13 studies found no spot reduction. Inner thigh moves strengthen the inner thigh muscles, as squats and leg presses do.

Sources 6, 7, 16

"Thigh fat is the dangerous kind"Emerging evidence

Observational studies link hip and thigh fat with lower, not higher, diabetes and heart risk than fat around the waist. They show an association, not proof.

"Leg training will make your thighs bulky"Strong evidence

Muscle grows slowly, and you control the dose: hold your sets and weights where they are when you're happy. Full squats added about 6% to the inner thigh muscles over 10 weeks in young men.

"Cellulite can be exercised or rolled away"Mixed evidence

No exercise has been shown to remove cellulite, and across 67 studies no treatment had clear evidence of working well. Our fascia blasting guide found no independent trials of the tools.

"Only overweight people get cellulite"Strong evidence

It affects 80 to 90% of women after puberty, of every size. Losing weight improved it for most women in one study but made it worse for some.
