The 5 Top Weight Loss APIs That Will Surprise You

Eva Medved

With half of Americans attempting to lose weight and become healthier[1], the market opportunity for apps is huge.

Building an app used to be reserved for tech whizzes or big corporations with big budgets, but in the last couple of years, more and more APIs are available that can simplify that process. This means that small to medium companies and even individuals, such as personal trainers, functional medicine doctors, and nutritionists, can take a prebuilt health and weight loss API and quickly, easily, and cheaply integrate it into a branded app to help their clients.

What are weight loss and health APIs?

API stands for Application Programming Interface. In not-so-technical terms, it’s software that lets two applications communicate with each other. APIs often have a database (of recipes, health content, different tracking tools, etc.) attached on one side, and the user application on the other. This means that the end-user gets to see the personalized and branded interface by your brand, but the API developers do the large chunk of the programming.

It’s also possible to integrate multiple smaller APIs combined to work together in a solution. An example could be a weight loss application that uses one API to parse nutrition information for specific foods, another to suggest nearby restaurants, and the third one for meal planning.

This blog post explores 5 APIs that support the weight loss journey from different points of view.

Conclusion

Weight loss is more complicated than just eating less and moving more. Research has shown that 80% of people who lose weight do not maintain the new weight for even a year[2], and as many as 95% regain it within 1 to 5 years[3]. Permanent weight loss requires a lasting change in habits, which is a matter of body and mind. The best weight loss apps combine tools for tracking, monitoring, and supporting the user throughout the health journey.
