Weight loss pens reduce food costs and can impact airline fuel consumption

Weight loss pens already have effects that go beyond health. A study of American families showed that, after six months of treatment, spending on supermarkets fell by 5.3%, on average, while spending on fast food, coffee shops and quick-service restaurants fell by around 8%.

There are also possible impacts being studied: a projection estimates that 10% lighter passengers could reduce aircraft fuel consumption by up to 1.5%. The phenomenon that began by changing appetite is now affecting consumption habits and different sectors of the economy.
