Gluteofemoral Fat
Gluteofemoral fat is the fat stored on the hips, buttocks and thighs; it behaves differently from belly fat and is linked to a lower, not higher, metabolic risk.
Plain English
Patient-Friendly Explanation
Two people can weigh the same and carry their fat in completely different places, and that difference matters. Gluteofemoral fat is the fat under the skin of the hips, buttocks and thighs - the pear-shaped pattern that is more common in women before menopause. It is not simply a passive store. Fat cells in the hips and thighs are relatively reluctant to release their contents: they take up circulating fats readily and let them go slowly, which keeps fatty acids out of the liver, muscles and pancreas where they do damage. They also release a friendlier mix of signals, with more adiponectin and less of the inflammatory messengers that visceral fat produces. Studies that measure hip and thigh size consistently find that a larger hip circumference, at any given body mass index, goes with a lower risk of diabetes and heart disease, while a bigger waist goes the other way. One striking piece of evidence is that surgically removing thigh and abdominal fat with liposuction does not improve blood sugar or cholesterol - the extra fat was not the problem, its location and biology were. This does not mean extra weight is harmless: total fat still counts, and South Asian and Chinese people often store less protective hip fat and more harmful abdominal fat at the same body mass index, which is why our thresholds are lower. It does mean that a pear shape is a better place to carry weight than an apple shape.

Clinical Definition
Gluteofemoral adipose tissue is predominantly subcutaneous and has a distinct metabolic phenotype: higher lipoprotein lipase activity, greater fatty acid uptake, reduced catecholamine-stimulated lipolysis (a higher ratio of antilipolytic alpha-2 to lipolytic beta-adrenergic receptors) and lower free fatty acid release than the visceral and abdominal subcutaneous depots, functioning as a lipid buffer or metabolic sink. Its secretory profile is relatively favourable, with higher adiponectin and lower IL-6 and TNF-alpha output. Observational data show that larger hip circumference and lower waist-to-hip ratio are associated with lower incident type 2 diabetes and cardiovascular disease at a given BMI, and that thigh subcutaneous fat is inversely associated with insulin resistance. Depot-specific causality is supported by interventions: large-volume liposuction of abdominal and thigh subcutaneous fat does not improve insulin sensitivity, lipids or inflammatory markers, indicating that intrinsic depot properties rather than fat mass alone drive risk. Mechanisms proposed include a protective role for the expandability of lower-body subcutaneous depots and for local oestrogen and androgen receptor signalling. Reproductive transitions shift distribution centrally - PCOS and the menopause reduce gluteofemoral storage - and Asian populations have lower hip and thigh subcutaneous fat at equivalent BMI, consistent with Asian-specific BMI and waist thresholds.
Key Insight
Why It Matters
If your weight sits on your hips and thighs, that is genuinely a better place for it than your waist - your body is storing it where it does less harm. It is not a reason to ignore weight, though: total fat still matters, and the hips-and-thighs pattern shifts towards the waist after menopause and with PCOS. The measurement we care about most is still your waist, and you cannot spot-reduce fat with exercise targeted at one area. When we track your progress we look at waist, hip and body composition together, not just the scale.
