Prioritize Aerobic Exercise: A meta-analysis of randomized trials found that aerobic training of moderate-to-high intensity reduces visceral (abdominal) fat in overweight adults, even without a hypocaloric diet. Running, cycling, swimming, and brisk walking all help mobilize central fat stores. Aim for 150+ minutes per week of moderate-intensity cardio. PLoS One
Manage Chronic Stress: Visceral fat carries a high density of glucocorticoid receptors, and chronic stress that elevates cortisol is associated with preferential central fat deposition. HPA axis dysregulation appears to shift fat storage toward central depots. Regular stress reduction - exercise, mindfulness, adequate sleep, social connection - supports healthier fat distribution. Clinical Obesity
Improve Diet Quality: Replace refined carbohydrates with whole grains, vegetables, and lean protein. In the DIRECT-PLUS randomized trial, Mediterranean dietary patterns were associated with greater loss of visceral fat. Soluble fiber from oats, legumes, and fruit may help, and limiting trans fats is prudent given their links to central fat deposition. BMC Medicine
Protect Sleep Duration: A meta-analysis of prospective cohorts found short sleep (mainly under 6 hours) associated with an 8% higher risk of abdominal obesity. Sleep restriction disrupts appetite signaling, which may promote caloric overconsumption and central fat storage. Consistent 7-8 hours of quality sleep supports healthier fat distribution. Obesity Science & Practice
Monitor Waist Circumference: Waist circumference is a simple, inexpensive proxy for central fat and cardiometabolic risk. The WHO flags increased risk above 94 cm for men and 80 cm for women, with a substantially increased risk above 102 cm and 88 cm respectively. Regular measurement can flag metabolic risk earlier than body weight alone. WHO

Background and further reading
Waist-hip ratio (WHR) is waist circumference divided by hip circumference. It captures where the body stores fat - centrally, around the abdomen, versus peripherally, around the hips and thighs. A high WHR reflects central (abdominal) adiposity, which tracks the metabolically active visceral fat that BMI alone can miss. The WHO defines abdominal obesity as a WHR above 0.90 in men and above 0.85 in women, thresholds linked to substantially increased cardiometabolic risk [4]. In studies that genetically separate fat distribution from overall body size, a higher WHR (adjusted for BMI) is associated with type 2 diabetes and coronary heart disease independently of BMI [3].
Genetic Basis: WHR (adjusted for BMI) is heritable, and its genetics show pronounced sexual dimorphism. Twin studies put the heritability of waist-hip ratio at roughly 30-60% (commonly around 40%, with higher estimates in women). The GIANT consortium's 2015 study identified 49 loci, about 20 of which differed by sex, with stronger effects in women [1]. A larger 2019 meta-analysis of roughly 700,000 people of European ancestry mapped 346 loci; SNP-based heritability - the share captured by common variants alone, lower than the twin figure - was higher in women (about 26%) than in men (about 17%), and around a third of signals were sex-specific [2]. Notable loci include RSPO3 and VEGFA, which act in adipose tissue development and vascularization, alongside LYPLAL1 and GRB14/COBLL1. The architecture is largely distinct from BMI - many variants shift fat distribution without changing overall adiposity [2].
Modifiable Factors: Fat distribution has strong genetic and hormonal determinants, but it still responds to lifestyle. You cannot spot-reduce belly fat, but overall fat loss draws down visceral stores, and aerobic training can reduce visceral fat even without much weight change [5]. Chronic stress raises cortisol, which favors central fat deposition, so stress management supports healthier distribution. Dietary quality - replacing refined carbohydrates with whole foods, healthy fats, and fiber - is associated with lower visceral fat. Short sleep is linked to greater abdominal adiposity. Hormonal shifts, such as menopause and falling testosterone, also move fat storage centrally.
