A fat tax is a tax or surcharge that is placed upon fattening food, beverages or individuals. As an example of Pigovian taxation, a fat tax aims to discourage unhealthy diets and offset the economic costs of obesity.
A fat tax aims to decrease the consumption of foods that are linked to obesity. A related idea is to tax foods that are linked to increased risk of coronary heart disease. Numerous studies suggest that as the price of a food decreases, individuals get fatter. In fact, eating behavior may be more responsive to price increases than to nutritional education. Estimates suggest that a 1 cent per ounce tax on sugar-sweetened beverages may reduce the consumption of those beverages by 25%. However, there is also evidence that obese individuals are less responsive to changes in the price of food than normal-weight individuals.
To implement a fat tax, it is necessary to specify which food and beverage products will be targeted. This must be done with care, because a carelessly chosen food tax can have surprising and perverse effects. For instance, consumption patterns suggest that taxing saturated fat would induce consumers to increase their salt intake, thereby putting themselves at greater risk for cardiovascular death. Taxation of sodium has been proposed as a way of reducing salt intake and resulting health problems. Current proposals frequently single out sugar-sweetened drinks as a target for taxation. Cross-sectional, prospective, and experimental studies have found an association between obesity and the consumption of sugar-sweetened drinks. However, experimental studies have not always found an association, and the size of the effect can be very modest.
Since the poor spend a greater proportion of their income on food, a fat tax might be regressive. Taxing foods that provide primarily calories, with little other nutritional value reduces this problem, since calories are readily available from many sources in diet of industrialized nations. To make a fat tax less burdensome for the poor, proponents recommend earmarking the revenues to subsidize healthy foods and health education. Additionally, proponents have argued that the fat tax is less regressive to the extent that it lowers medical expenditures and expenditures on the targeted foods among the poor. Indeed, there is a higher incidence of diet-related illnesses among the poor than in the general population.
Unlike placing restrictions on foods or ingredients, a fat tax would not limit consumer choice, only change relative prices.
In 1942, U.S. physiologist A. J. Carlson suggested levying a fee on each pound of overweight, both to counter an "injurious luxury" and to make more food available for the war effort. The concept was reintroduced by Milton Merryweather and P. Franklin Alexander in the late 1970s, but became well known in the early 1980s by Kelly D. Brownell, director of the Rudd Center for Food Policy and Obesity at Yale. Brownell proposed that revenue from junk-food taxes be used to subsidize more healthful foods and fund nutrition campaigns.
In a 1994 Op-Ed in the New York Times, Brownell noted that food costs were out of balance, with healthy foods costing more than unhealthy ones. The New York Times Op-Ed piece that proposed the "fat tax" elicited controversy and outrage nationwide. Author Kelly Brownell became the focal point of this controversy, especially from Rush Limbaugh, who spoke out adamantly against the tax and the general principle of governmental intrusion into food choices and a possible invasion of privacy. Brownell’s proposal was listed as number seven on the list of U.S. News & World Report's "16 Smart Ideas to Fix the World." Because of this and other work, Brownell was named by Time Magazine as one of the "World's Most Influential People." In 2000 a paper in the British Medical Journal outlined the potential impact on deaths from ischaemic heart disease of a tax on the main sources of saturated fats. In December 2003, The World Health Organization proposed that nations consider taxing junk foods to encourage people to make healthier food choices. According to the WHO report, "Several countries use fiscal measures to promote availability of and access to certain foods; others use taxes to increase or decrease consumption of food; and some use public funds and subsidies to promote access among poor communities to recreational and sporting facilities."
Bruce Silverglade, director of legal affairs for the Center for Science in the Public Interest, said his nonprofit nutrition advocacy organization welcomed the recommendations and has spent years fighting for measures like a Junk Food Tax. The proposal got more traction when New York Assemblyman Felix Ortiz proposed taxes on junk food and entertainment contributing to sedentary lifestyles to fund nutrition and exercise programs. It should also be remembered[weasel words] that taxing foodstuffs is not an argument for increasing taxation. Other taxes can be reduced commensurately if the overall objective is to keep the tax take neutral. The fat tax is an argument for raising taxes on activities that we prefer to discourage (consumption of certain foodstuffs) rather than raising taxes on socially desirable activities. Therefore opponents of this type of taxation must identify which taxes are preferable to taxing these foodstuffs.[original research?]
Other advocates of the tax[who?] point to the effect taxes have had on alcohol and tobacco use. Five studies published between 1981 and 1998 found that drinking declined as the price of alcohol increased. The same holds for tobacco. In California in 1988, Proposition 99 increased the state tax by 25 cents per cigarette pack and allocated a minimum of 20% of revenue to fund anti-tobacco education. From 1988 to 1993, the state saw tobacco use decline by 27%, three times better than the U.S. average.
Japan implemented a measurement of waist sizes during 2008 to help avoid the obesity epidemic confronting the United States. The New York Times wrote: "To reach its goals of shrinking the overweight population by 10 percent over the next four years and 25 percent over the next seven years, the government will impose financial penalties on companies and local governments that fail to meet specific targets. The country’s Ministry of Health argues that the campaign will keep the spread of diseases like diabetes and strokes in check." The average male waist size in Japan is smaller than the average in the U.S.
A CBS News poll from January 2010 reported that a tax on items such as soft drinks and foods considered to be junk food, is opposed 60% to 38%. An even larger number, 72% of Americans, also believed that a tax would not actually help people lose weight. While a February 2010 poll by the Quinnipiac University Polling Institute found that New York residents overwhelmingly favor a soft drink tax, with 76 percent wanting the tax, and 22 percent opposing it. The poll found both Republicans and Democrats favor the tax. However it should be[weasel words] remembered that the question of whether or not taxation influences diet is an empirical question and not simply a matter of public opinion.
In October 2011, Denmark introduced a fat tax on butter, milk, cheese, pizza, meat, oil and processed food if the item contains more than 2.3% saturated fat. However, in November 2012, the Danish Tax Ministry announced it would abolish the fat tax, stating that it failed to change Danes' eating habits, it had encouraged cross border trading, put Danish jobs at risk and had been a bureaucratic nightmare for producers and outlets. The proposed sugar tax plans were also scrapped.
Mette Gjerskov, the Danish minister of food, agriculture and fisheries, stated that "the fat tax is one of the most criticized we had in a long time. Now we have to try to improve public health by other means.” Although the tax resulted in an additional $216 million in revenue, it also led to numerous complaints from Danish retailers that their customers were taking their business to other countries, such as Sweden and Germany, to take advantage of their lower prices.
Scientific research 
Taxing soft drinks and pizza can decrease the amount of calories that people consume from these foods. The study found that a 10 percent tax on soda led to a 7 percent reduction in calories from soft drinks, and a 10 percent tax on pizza led to a 12 percent reduction in calories from pizza. These researchers believe that an 18 percent tax on these foods could cut daily intake by 104 calories per person, resulting in a weight loss of 2 pounds (0.9 kg) per person per year. The study followed 5,115 young adults ages 18 to 30 from 1985 to 2006.
