Obesity in India has reached epidemic proportions in the 21st century, with morbid obesity affecting almost 3% of the country's population (BMI of above 30 in India). [1] India is following a trend of other developing countries that are steadily becoming more obese. Around 15-20% of the population is overweight (having an BMI above 23). India follows a different BMI calculation since South Asians store more body fat and are at a higher risk of weight-related diseases than other ethnic groups. A BMI above 23 is considered overweight, 25 is obese, and 30 is morbidly obese. Unhealthy, processed food has become much more accessible following India's continued integration in global food markets. Fast food outlets and unhealthy snacks and foods have become common in villages and cities alike. This, combined with rising middle class incomes, is increasing the average caloric intake per individual among middle class and high income households. [2] Obesity is a major risk factor for cardiovascular disease, and NGOs such as the Indian Heart Association have been raising awareness about this issue. [3]
While studying 22 different SNPs near to MC4-R gene, scientists have identified an SNP (single nucleotide polymorphism) named rs12970134 to be mostly associated with waist circumference. In this study more than two thousand individuals of Indian origin participated and the aforementioned SNP is highly prevalent in this group. [4]
Internationally, a BMI over 25 kg/m^2 is considered overweight. Due to genetic tendency of Indians towards abdominal obesity and its associated risk of related lifestyle diseases such as diabetes and anemia, guidelines for diagnosis of obesity and abdominal obesity for India have been published in JAPI (2009) that a BMI over 23 kg/m^2 is considered overweight. [5] Further definitions: Normal BMI: 18.0-22.9 kg/m^2, Overweight: 23.0-24.9 kg/m^2, Obesity: >25 kg/m^2. [5]
This is a list of the states of India ranked in order of percentage of people who are overweight or obese, based on data from the 2016-2021National Family Health Survey. [6]
A BMI of above 25 is considered overweight in India, and over 30 is obese.

Body mass index (BMI) is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2, resulting from mass in kilograms (kg) and height in metres (m).
Metabolic syndrome is a clustering of at least three of the following five medical conditions: abdominal obesity, high blood pressure, high blood sugar, high serum triglycerides, and low serum high-density lipoprotein (HDL).
Abdominal obesity, also known as central obesity and truncal obesity, is the human condition of an excessive concentration of visceral fat around the stomach and abdomen to such an extent that it is likely to harm its bearer's health. Abdominal obesity has been strongly linked to cardiovascular disease, Alzheimer's disease, and other metabolic and vascular diseases.
Obesity is a medical condition, sometimes considered a disease, in which excess body fat has accumulated to such an extent that it negatively affects health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over 30 kg/m2; the range 25–30 kg/m2 is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis.
The waist is the part of the abdomen between the rib cage and hips. On people with slim bodies, the waist is the narrowest part of the torso.
The waist–hip ratio or waist-to-hip ratio (WHR) is the dimensionless ratio of the circumference of the waist to that of the hips. This is calculated as waist measurement divided by hip measurement. For example, a person with a 75 cm waist and 95 cm hips has WHR of about 0.79.
Childhood obesity is a condition where excess body fat negatively affects a child's health or well-being. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health concern. The term 'overweight' rather than 'obese' is often used when discussing childhood obesity, as it is less stigmatizing, although the term 'overweight' can also refer to a different BMI category. The prevalence of childhood obesity is known to differ by sex and gender.
Obesity is common in the United States and is a major health issue associated with numerous diseases, specifically an increased risk of certain types of cancer, coronary artery disease, type 2 diabetes, stroke, and cardiovascular disease, as well as significant increases in early mortality and economic costs.
Obesity has been observed throughout human history. Many early depictions of the human form in art and sculpture appear obese. However, it was not until the 20th century that obesity became common — so much so that, in 1997, the World Health Organization (WHO) formally recognized obesity as a global epidemic and estimated that the worldwide prevalence of obesity has nearly tripled since 1975. Obesity is defined as having a body mass index (BMI) greater than or equal to 30 kg/m2, and in June 2013 the American Medical Association classified it as a disease.
Diet plays an important role in the genesis of obesity. Personal choices, food advertising, social customs and cultural influences, as well as food availability and pricing all play a role in determining what and how much an individual eats.
According to 2007 statistics from the World Health Organization (WHO), Australia has the third-highest prevalence of overweight adults in the English-speaking world. Obesity in Australia is an "epidemic" with "increasing frequency." The Medical Journal of Australia found that obesity in Australia more than doubled in the two decades preceding 2003, and the unprecedented rise in obesity has been compared to the same health crisis in America. The rise in obesity has been attributed to poor eating habits in the country closely related to the availability of fast food since the 1970s, sedentary lifestyles and a decrease in the labour workforce.
Pacific island nations and associated states make up the top seven on a 2007 list of heaviest countries, and eight of the top ten. In all these cases, more than 70% of citizens aged 15 and over are obese. A mitigating argument is that the BMI measures used to appraise obesity in Caucasian bodies may need to be adjusted for appraising obesity in Polynesian bodies, which typically have larger bone and muscle mass than Caucasian bodies; however, this would not account for the drastically higher rates of cardiovascular disease and type 2 diabetes among these same islanders.
Obesity classification is a ranking of obesity, the medical condition in which excess body fat has accumulated to the extent that it has an adverse effect on health. The World Health Organization (WHO) classifies obesity by body mass index (BMI). BMI is further evaluated in terms of fat distribution via the waist–hip ratio and total cardiovascular risk factors. In children, a healthy weight varies with age and sex, and obesity determination is in relation to a historical normal group.
Android fat distribution describes the distribution of human adipose tissue mainly around the trunk and upper body, in areas such as the abdomen, chest, shoulder and nape of the neck. This pattern may lead to an "apple”-shaped body or central obesity, and is more common in males than in females. Thus, the android fat distribution of men is about 48.6%, which is 10.3% higher than that of premenopausal women. In other cases, an ovoid shape forms, which does not differentiate between men and women. Generally, during early adulthood, females tend to have a more peripheral fat distribution such that their fat is evenly distributed over their body. However, it has been found that as females age, bear children and approach menopause, this distribution shifts towards the android pattern of fat distribution, resulting in a 42.1% increase in android body fat distribution in postmenopausal women. This could potentially provide evolutionary advantages such as lowering a woman's center of gravity making her more stable when carrying offspring.
A person's waist-to-height ratio (WHtR), occasionally written WtHR or called waist-to-stature ratio (WSR), is defined as their waist circumference divided by their height, both measured in the same units. It is used as a predictor of obesity-related cardiovascular disease. The WHtR is a measure of the distribution of body fat. Higher values of WHtR indicate higher risk of obesity-related cardiovascular diseases; it is correlated with abdominal obesity.
Obesity in Pakistan is a health issue that has effected concern only in more recent years. Urbanisation, fast food, changing lifestyles and the fact that Traditional Pakistani Cuisine tends to be high in fat, carbohydrates, oil, salt and sugar are among the root causes contributing to obesity in the country. Pakistan is the most obese country in South Asia.
TOFI (thin-outside-fat-inside) is used to describe lean individuals with a disproportionate amount of fat stored in their abdomen. The figure to illustrate this shows two men, both 35 years old, with a BMI of 25 kg/m2. Despite their similar size, the TOFI had 5.86 litres of internal fat, whilst the healthy control had only 1.65 litres.
A Body Shape Index (ABSI) or simply body shape index (BSI) is a metric for assessing the health implications of a given human body height, mass and waist circumference (WC). The inclusion of WC is believed to make the BSI a better indicator of risk of mortality from excess weight than the standard body mass index. ABSI correlates only slightly with height, weight and BMI, indicating that it is independent of other anthropometric variables in predicting mortality.
Obesity is defined as the excessive accumulation of fat and is predominantly caused when there is an energy imbalance between calorie consumption and calorie expenditure. Childhood obesity is becoming an increasing concern worldwide, and Australia alone recognizes that 1 in 4 children are either overweight or obese.
Obesity in Thailand has been flagged as a major source of health concern, with 32% of the population identifying as overweight and 9% obese. With reference to 2016 data from the World Health Organization (WHO), Thailand has one of the highest incidence of overweight citizens in the South East Asian region, second to only Malaysia. The Thai National Health Examination Surveys (NHES) found that obesity in Thailand more than doubled during the period 1991-2014. This spike in obesity levels has been largely attributed to increased access to junk food, and unhealthy switches from active to sedentary lifestyles. These factors are closely linked to economic growth in the country.
