Saudi Obesity Rate: The Official Figure Is 23%. Independent Estimates Say 43%.

Between 23% and 46%, depending on how it is measured. That range is the honest answer to the question of the obesity rate in Saudi Arabia, and the reason no single page has owned the query. The official figure, published by the General Authority for Statistics (GASTAT) on 18 November 2024, is 23.1% of the population aged 15 and over, with a further 45.1% classified as overweight [S1]. The most widely circulated independent figure, a projection distributed through Statista, is 42.9% for 2026 [S2]. Both numbers are real. Neither is wrong. They measure different things in different ways, and almost nobody says so.

This matters more than a statistical footnote. The two figures support opposite conclusions about the same country. At 23.1%, Saudi Arabia looks broadly comparable to Western Europe. At 43%, it belongs in the small group of countries where obesity has become the dominant modifiable driver of chronic disease. Health ministries, insurers, pharmaceutical strategists, investors in the healthcare sector and journalists all cite one or the other, usually without noting which, and the resulting literature is internally contradictory in a way that looks like a data-quality scandal but is not one.

It is not a scandal because self-reported height and weight is a legitimate, internationally standard survey method with a documented and quantified limitation. Dozens of national statistics agencies use it. GASTAT publishes its methodology, and the World Obesity Federation, reproducing the Saudi figure on its own country card, labels it plainly: survey type, self-reported [S3]. The failure is downstream, in citation practice — in the habit of lifting a self-reported number and deploying it as though it were a clinical measurement. This page sets out every published figure, explains precisely why they diverge, and answers the question that none of the competing sources answers: which one to use, and for what.

The short version. Saudi Arabia’s official obesity prevalence is 23.1% among those aged 15 and over (GASTAT, 2024, self-reported). Nationally measured surveys have found 20.2% (2019, all residents) and 28.7% (2013, Saudi nationals only). Modelled and clinical estimates run from 33.7% (WHO) to 46.4% (a 74,881-patient hospital dataset). Use the official series for trend and official reporting; use a measured or modelled figure for disease burden and international comparison.

What Is the Obesity Rate in Saudi Arabia?

The official answer is 23.1%, for the population aged 15 and over, from GASTAT’s Health Determinants Statistics Publication 2024, released 18 November 2024. That publication also reports 45.1% overweight among the same group, 14.6% obesity and 33.3% overweight among children aged 2 to 14, and that only 10.2% of the population meets the recommended five daily servings of fruit and vegetables [S1]. The adult sample is large — 73,544 respondents — and nationally representative, drawn from the National Health Survey and collected through computer-assisted personal interviews [S3].

Every other figure in circulation comes from a differently constructed study. The table below is the full published record, with the method stated for each, because the method is what determines the number.

Sources: [S1] [S2] [S3] [S4] [S5] [S6] [S7] [S8].

Two rows deserve immediate attention because they bracket the range. The 2019 Kingdom of Saudi Arabia World Health Survey (KSAWHS), run by the Ministry of Health with GASTAT and the Saudi Health Council, found 20.2% obesity and 38.2% overweight, with a mean body mass index of 26.4 kg/m² [S4] [S9]. Critically, and contrary to how it is often described, that survey did not rely on self-report for anthropometry: its Biological Risk Factors report states that the figures were “measured through a clinical health examination and a blood test”, and carries an explicit warning that its percentages “may not be identical to the percentages that participants self-reported” in other publications [S4]. It is a measured survey, and it produced a low number.

At the other end, Alshahrani et al., publishing in BMC Public Health on 7 March 2026, analysed measured height and weight from the electronic health records of 74,881 adult patients across nearly a million visits between January 2017 and April 2025. They found 46.4% obese — 26.6% class 1, 13.3% class 2 and 6.5% class 3 — with a further 32.7% overweight and only 20.9% at a normal BMI [S8]. The sample size is almost identical to GASTAT’s. The number is double.

Why Do Obesity Figures for Saudi Arabia Differ So Much?

Four distinct mechanisms are at work, and they do not all push in the same direction. Untangling them is the whole exercise.

Self-reported height and weight systematically understate BMI

This is the best-documented effect and the one most relevant to the headline figure. When people are asked to state their own height and weight rather than being measured, the reported values skew in a consistent direction: height is rounded up, weight is rounded down, and both errors move the resulting BMI downward. Because BMI is weight divided by the square of height, a small overstatement of height has an outsized deflationary effect. The bias is not random noise that cancels out across a large sample — it is directional, so a bigger sample makes the estimate more precisely wrong rather than more accurate.

Saudi researchers state the limitation openly in their own papers. Mohieldin and colleagues at King Khalid University, reporting 25.3% obesity in the Aseer region in AIMS Public Health in December 2025, write that because “height and weight were self-reported, the true prevalence of obesity may be underestimated” [S6]. Alsulami and colleagues, writing in Frontiers in Public Health in March 2023, record the same caveat: “because height and weight are self-reported, they may be underestimated or overstated” [S10]. Neither team is criticising the Saudi statistical system. Both are applying the ordinary discipline of stating what their instrument can and cannot see.

The population being counted changes between surveys

This mechanism is specific to Saudi Arabia and is routinely missed. Roughly 44% of the Kingdom’s residents are non-Saudi, a population skewed heavily towards working-age men in manual and service occupations, whose measured BMI distribution differs materially from that of Saudi nationals. Whether a survey covers Saudi citizens only or all residents therefore changes the headline number substantially, entirely independently of measurement method.

The 2013 Saudi Health Interview Survey sampled 10,735 Saudi nationals aged 15 or over, with physical measurements and a biomedical examination, and found 28.7% obesity — 33.5% among women, 24.1% among men [S5]. The 2019 KSAWHS sampled all resident households and found 20.2%. Read naively, that is an eight-point fall in national obesity across six years, which no plausible epidemiology supports. Read correctly, it is largely a change of denominator. Any comparison of Saudi obesity figures that does not check the expatriate population treatment is comparing two different countries.

Age ranges and standardisation are not aligned

GASTAT’s headline covers ages 15 and over. WHO’s modelled country estimates and most international comparisons cover 18 and over, age-standardised to a reference population. Adolescents have markedly lower obesity prevalence than adults — GASTAT’s own age breakdown shows obesity at 12.5% among men aged 20 to 24, rising to 48% among women aged 65 to 69 [S3] — so folding 15-to-17-year-olds into an adult denominator mechanically drags the average down. Age-standardisation, which the raw survey figure does not apply, adjusts for the fact that Saudi Arabia has a young population relative to the OECD comparators it is usually measured against.

Modelled estimates correct for what surveys cannot see

WHO’s country estimate for Saudi Arabia, cited in the peer-reviewed literature as 33.7% obesity (39.5% among women, 29.5% among men) and 68.2% overweight or obese combined, is not a survey result [S10]. It is a modelled figure, produced by pooling population-representative studies and adjusting for known biases — including self-report — to generate a comparable estimate across countries. The Statista series that yields 42.9% for 2026, attributed to Nahdi Medical Company and rising from 36.8% in 2016, is likewise a projection rather than a count [S2].

Modelled figures are not more “true” than survey figures. They are constructed for a different purpose: cross-country comparability and burden estimation, at the cost of not being a direct observation of anybody.

The 97.4% clue, and a clean internal test

There is a way to size the self-report effect using only Saudi data, with no foreign comparison required.

GASTAT’s companion Health Status Statistics publication, released 19 December 2024, reports that 97.4% of the population aged 15 and over rate their own health as good or better, and that 18.95% report at least one chronic illness — self-reported diabetes at 9.1%, hypertension at 7.9%, raised cholesterol at 3.6%, cardiovascular disease at 1.5% and cancer at 0.6% [S11]. A 97.4% positive self-assessment is not a claim about the population’s clinical status; it is a measurement of how people describe themselves, which is exactly what a self-report instrument is designed to capture.

Now set the self-reported hypertension figure against the measured one. GASTAT’s respondents self-reported hypertension at 7.9%. The 2019 KSAWHS, taking actual blood-pressure readings from a comparable 15-plus population, found 14% with raised blood pressure [S4]. Self-report captured roughly half the measured prevalence — for a condition that is, in the clinical phrase the survey itself uses, largely asymptomatic. The same instrument that halves hypertension is the instrument producing the 23.1% obesity figure. On diabetes, the International Diabetes Federation places Saudi Arabia among the ten countries with the highest adult prevalence globally, against a self-reported 9.1% [S12].

None of this makes GASTAT’s numbers defective. They are accurate measurements of self-assessment, which is a legitimate and useful thing to measure. They are simply not measurements of body composition, and they should not be redeployed as though they were.

Which Obesity Figure Should You Cite, and for What?

This is the practical question, and the reason a single page can own this topic. There is no single correct obesity rate in Saudi Arabia to quote in all settings; the answer is not “use the higher number” but depends entirely on the use.

Three rules follow, and they apply to any statistic of this shape.

Never mix methods inside a single trend line. The apparent decline from 28.7% in 2013 to 20.2% in 2019 to 23.1% in 2024 is not a trend. It is three different studies. Within the GASTAT series alone, the trend is meaningful; across the three, it is an artefact.

Always state the method beside the number. “23.1% (GASTAT 2024, self-reported, ages 15+)” is a usable citation. “23.1%” alone is not.

Treat the range as information, not as noise. The spread from 20.3% to 57% in Al-Omar and colleagues’ systematic review of 78 studies, published in the Saudi Pharmaceutical Journal in October 2024, is not evidence that Saudi obesity data are unreliable [S7]. It is evidence that prevalence varies enormously by region, sample and instrument — from 20.3% in Hail to 57% in Bisha — which is itself the finding.

Is Saudi Arabia One of the Most Obese Countries?

On measured and modelled estimates, yes; on its own official figure, less obviously. WHO recorded global adult obesity at 16% in 2022, so a measured Saudi Arabia obesity rate anywhere in the 33% to 46% band places the Kingdom far above the world average and among the higher-prevalence countries outside the Pacific islands and the Gulf. The Ministry of Health’s own awareness material states that Saudi Arabia ranks third in the Arab world for obesity [S9].

At 23.1%, however, Saudi Arabia would sit in the same band as several European countries — which is precisely the misreading the self-reported figure invites when it travels into league tables built from measured data. A ranking that mixes self-reported and measured national figures does not rank obesity. It ranks candour.

The systematic review’s ceiling of 57% in Bisha, and the 46.4% measured in the Armed Forces Hospitals Southern Region dataset, both point the same way [S7] [S8]. Neither is a national estimate — the hospital dataset in particular describes a clinical population that over-represents people already in contact with health services, and should be read as an upper bound rather than a prevalence figure. But an upper bound of 46% and a national self-report of 23% cannot both describe the same distribution.

Are Saudi Women More Obese Than Saudi Men?

Yes, marginally, and by much less than historic data would suggest. GASTAT’s 2024 figures put obesity at 23.5% among women and 22.8% among men — a gap of 0.7 percentage points. Overweight prevalence inverts, at 46.3% for men against 42.6% for women [S3]. On the combined overweight-or-obese measure, men are higher.

The 2019 measured survey found a similar pattern: obesity at 21.4% among women and 19.2% among men, with overweight at 43% for men against 33% for women [S4] [S9]. The 2013 measured SHIS, covering Saudi nationals only, recorded a far wider female-male obesity gap of 33.5% against 24.1% [S5]. Whether that gap has genuinely narrowed, or whether the change reflects the shift to an all-resident denominator with its large male expatriate component, cannot be resolved from the published figures alone. It is one of the more consequential open questions in the dataset, given how much Vision 2030 policy — from the Quality of Life Programme to the youth physical activity KPI — is directed at participation gaps between men and women.

Age is a stronger determinant than sex. GASTAT’s breakdown shows obesity climbing from around 12% in the early twenties to a peak of 48% among women aged 65 to 69, before falling back [S3].

What Does Obesity Cost the Saudi Economy?

$19.59bn a year, or 2.4% of GDP, on the World Obesity Federation’s estimate — equivalent to $572 per capita — and projected to reach $150.46bn, or 5.6% of GDP, by 2060 [S13]. That is the most widely cited economic figure and the one that most directly connects obesity to the fiscal arithmetic of the transformation.

An independent peer-reviewed estimate reaches a similar headline by a different route. Malkin and Finkelstein, writing in PLoS One in March 2022, put the 2019 cost of overweight and obesity in Saudi Arabia at $19.3bn: $3.8bn in direct medical costs, equal to 4.3% of health expenditure, and $15.5bn in indirect costs from absenteeism and presenteeism, equal to 0.9% of GDP [S14]. Their total share of GDP, at roughly 1.1%, is well below the World Obesity Federation’s 2.4%, because the two models scope and discount productivity losses differently. The convergence on approximately $19bn from two independent methodologies is the more robust finding; the GDP share should be quoted with its source attached.

The clinical mechanism behind the cost is visible in the comorbidity data. Al-Omar and colleagues found that among people with obesity in the Saudi studies they reviewed, 67.6% had hypertension, 60.7% had type 2 diabetes and 51.3% had hypercholesterolaemia [S7]. The electronic-health-record study shows the same gradient prospectively: type 2 diabetes rises from 34% among patients with a normal BMI to 56% among those with class 3 obesity, and hypertension from 23% to 43% [S8]. These are the conditions that drive the chronic-disease load carried by healthcare spending and by the hospital estate.

What Saudi Arabia Is Doing About Obesity

The policy apparatus is real, dated and expanding, and it has moved twice in the last thirteen months.

Fiscal. Saudi Arabia introduced selective excise taxes in mid-2017, at 50% on soft drinks and 100% on energy drinks and tobacco. From 1 January 2026 that flat ad valorem rate was replaced by a four-tier levy calculated on sugar content per 100ml, following approval by the Zakat, Tax and Customs Authority (ZATCA) board in December 2025 and by the GCC Financial and Economic Cooperation Committee in October 2025. Beverages with no sugar or under 5g per 100ml are untaxed; 5g to 7.99g attracts SAR0.79 ($0.21) per litre; 8g or more attracts SAR1.09 ($0.29) per litre [S15]. ZATCA framed the change as intended to “promote public health and encourage reduced sugar consumption” by giving producers a direct incentive to reformulate — a structural shift from taxing a product category to taxing an ingredient, and a meaningful upgrade to the excise tax framework.

Regulatory. From 1 July 2025, the Saudi Food and Drug Authority (SFDA) requires restaurants and cafés to display calorie counts on physical and digital menus, including on food delivery platforms, alongside a saltshaker symbol on high-sodium dishes, caffeine content on beverages, and an estimate of the time required to expend each item’s calories [S16].

Programmatic. The Health Sector Transformation Programme has shifted the Ministry of Health towards a preventive model, and the Quality of Life Programme carries the physical-activity and community-sport objectives. Both are tracked against the wider health and wellbeing priority of Vision 2030.

What the apparatus lacks is a headline obesity target with a published baseline and a measurement protocol — the thing that would make progress checkable.

Why This Matters for Vision 2030

Saudi Arabia’s flagship health outcome is genuinely on track. Life expectancy reached 79.7 years in 2025, against a Vision 2030 target of 80 and a 2016 baseline of about 74 [S17]. On the life expectancy KPI, the Kingdom is within striking distance of a target most observers considered ambitious, and the Health Sector Transformation Programme’s 2025 annual report, reported on 3 December 2025, sets out the supporting gains: traffic-related deaths down about 60% since 2016, deaths from infectious disease down 50%, non-communicable disease mortality down 40%, emergency response times cut from 25 minutes to 10, weekly surgical capacity doubled from 6,000 to 12,000 operations, and 90% of surgeries meeting national timing standards against 60% previously. Health Minister Fahd Al-Jalajel presented the report [S17].

Obesity appears nowhere in it.

That is the tension worth naming. The programme reports extensively on acute care, access and mortality — the domains where Vision 2030 KPIs have moved fastest — while the single largest modifiable driver of the chronic-disease burden that will determine whether life expectancy clears 80 and keeps rising is absent from the scorecard. The 2025 report also gives no figures on private health insurance coverage or on privatisation progress, both of which sit inside the programme’s own remit and connect directly to health insurance market development and the HSTP delivery record.

The arithmetic is unforgiving. Mortality gains from road safety, infectious disease control and emergency response are largely front-loaded: they are achieved once and then plateau. The remaining distance to 80 years, and every year beyond it, has to come from chronic disease — which means from the cardiometabolic conditions that track body composition. A health system can add capacity indefinitely, as Saudi Arabia is doing through hospital expansion and platforms such as the Seha Virtual Hospital, and still lose ground on outcomes if incidence keeps rising.

There is a measurement problem embedded in the policy problem. If the official Saudi Arabia obesity rate is biased low by a wide and unquantified margin, then demand forecasts built on it under-provision, and any future improvement in the self-reported number is uninterpretable — it could reflect a real fall in prevalence or a change in how people describe themselves. The healthcare quality index and healthcare coverage trackers face the same structural issue wherever they depend on self-assessment.

Risks, Contradictions and Open Questions

No national measured survey has been published since 2019. As of 31 July 2026, the most recent measured, nationally representative anthropometric data for Saudi Arabia are seven years old. Everything published since is either self-reported, modelled, regional or drawn from a clinical population. This is the single largest gap in the evidence base.

The 2013-to-2019 decline is unexplained in the published record. The shift from 28.7% to 20.2% is most plausibly a denominator change from Saudi nationals to all residents, but no official reconciliation has been published. Until one is, the historical series cannot be read as a trend.

The 46.4% electronic-health-record figure is not a national estimate. It describes patients of the Armed Forces Hospitals Southern Region, a group that over-represents people in contact with health services and is regionally concentrated. It establishes that measured prevalence in a large Saudi clinical population is roughly double the self-reported national figure. It does not establish that national prevalence is 46.4%.

The 42.9% figure for 2026 is a projection, not an observation. It derives from a Nahdi Medical Company series distributed by Statista and published in 2022 and 2023 — before the GASTAT 2024 release — and no reconciliation between the two has been attempted by either party [S2]. It is the most-quoted independent number precisely because it is the most accessible, not because it is the best evidenced. The Statista page is also paywalled, which is part of why the query has stayed unresolved.

The direction of the self-report bias is documented; its magnitude in Saudi Arabia is not. The internal hypertension comparison — 7.9% self-reported against 14% measured — is suggestive but covers a different condition, and the two surveys are five years apart. A validation study measuring and self-reporting the same Saudi respondents would settle it. None has been published.

Whether the Saudi Arabia obesity rate is still rising is genuinely uncertain. The electronic-health-record series reports a consistent rise across 2017 to 2025, with a dip in 2019 and 2020 [S8]. The official series cannot answer the question because its method changed.

Our own corpus carries a legacy figure. The life expectancy tracker refers to obesity “exceeding 35 per cent of the adult population” — consistent with the modelled band set out here, but predating both the GASTAT 2024 release and the 2026 clinical evidence, and stated without its method.

What to Watch Next

GASTAT’s next Health Determinants publication, expected on the annual cycle established by the 18 November 2024 release. The number to watch is not the headline but whether the methodology note is expanded, and whether any measured sub-sample is introduced.

Any successor to the 2019 KSAWHS. A second measured national survey would resolve most of the open questions in a single publication. No date has been announced.

The 2026 Health Sector Transformation Programme annual report, due around December 2026 on the pattern of the 3 December 2025 release. Whether an obesity or BMI indicator appears is the clearest available signal of whether prevention has been elevated from rhetoric to measured target.

First-year data on the sugar-content excise, covering calendar 2026. Because the tiered levy creates a direct reformulation incentive at 5g and 8g per 100ml, the observable near-term effect is on product formulation and on the tax base rather than on prevalence. Beverage-category shifts in ZATCA collections through 2026 and 2027 are the leading indicator.

Life expectancy reporting for 2026. Movement from 79.7 towards 80 against the Vision 2030 target will show whether the acute-care gains still have room to run, or whether the chronic-disease ceiling is starting to bind.
