Losing weight can become a pressing health concern for many people. When people consume more energy than what they burn, it can lead to weight gain. In certain cases, this can even lead to obesity. Obesity has been declared as an epidemic by health experts around the world. It is important to realize that gaining excess weight can cause other health issues as well such as diabetes, heart disease, and even certain types of cancer.

According to the CDC, 42.4% of adults were obese in the U.S alone in 2018 and the United States has the highest rate of obesity in the world. The situation is alarming and points towards a significant public health crisis. While weight gain can be caused by different social, environmental, and genetic factors, the primary cause of obesity in the US is said to be poor diet and exercise. As a result, there has been an increase in weight-loss programs and fad diets over the past few years with more and more people looking to find the best ways to lose weight.

Many people are making the switch to plant-based foods which are more nutritious, have lower fat content, and can have many other health benefits as well. Moreover, research has shown that vegetarians have a lower body mass index than nonvegetarians. Companies like Beyond Meat, Inc. (NASDAQ: BYND) have created innovative plant-based meat substitutes that can have become increasingly popular in the US and around the world. They have created products that can replace beef, ground meat, sausages, patties, and meatballs.

Similarly, many Americans are looking for newer diets and weight loss products to help them lose weight. According to the Boston Medical Center, 45 million US residents go on a diet and spend approximately $33 billion on weight loss products each year. Moreover, many people are also turning to technology for help. For example, Noom is a health and fitness app that provides a customized weight loss diet plan which helps its users lose weight according to their personal weight goals. The app provides users with a health coach as well.

According to Research and Markets, the weight loss industry in the US was valued at $78 billion as of 2019. However, the pandemic caused a decline in value during 2020. Yet many weight loss companies increased sales by introducing new weight loss products and trends that have set them on a growth path. For example, Medifast, Inc. (NYSE: MED) is a Maryland-based company that exclusively deals with weight loss, weight management, and other nutritional products in the US and around the world. The company has shown strong financial performance and currently has a market cap of $3.338 billion. Medifast, Inc. (NYSE: MED) has also introduced a lifestyle solution and coaching support system which is a major driver of its growth.

Similarly, Herbalife Nutrition Ltd. (NYSE: HLF) is another wellness company that produces weight management and targeted nutrition products such as protein shakes, weight loss enhancers, meal replacement products, drink mixes, and healthy snacks. Herbalife Nutrition Ltd. (NYSE: HLF) reported a total revenue of $1.5 billion for Q1 of 2021 and currently has a market cap of $5.645 billion.
