Frequently asked questions

What do I need?

The only thing you need to participate is one of the compatible smart scales listed below.

Will anyone be able to see my weight?

No. Your weight will not be displayed anywhere on Thinvested (not even to you). There are plenty of great apps out there for tracking your weight and body fat, including those published by Fitbit, iHealth, and Withings. Our focus is solely on financial health incentives. We will only display a chart of your earnings over time, which will look similar to a stock chart.

Where do the investments come from?

Investments can come from family, friends, coworkers, employers, gyms, health insurers, and even governments. Funds can be raised at any time from multiple sources.

Will I really be able to raise investments from organizations?

Yes, but probably not for a while. Building partnerships with large organizations takes time; fortunately, so does (healthy) weight loss. For now, focus on raising investments from friends and family—you may be surprised by how eager they are to be involved. You can raise additional investments at any time, and we'll let you know when new opportunities become available in your area.

How are my earnings calculated?

Your earnings are proportional to the percentage of excess weight lost from the time each individual investment is made. This means you'll be able to cash out 100% of your available funds when you reach the upper end of a healthy weight range: a BMI below 25 and a body fat percentage below 31% for women and 24% for men. You can calculate your current BMI using this calculator.

While these standards will be suitable for many users, we realize that every body is different. If you have a specific recommendation from a healthcare professional, email us the details at and we'll be happy to tailor your account accordingly.

How often do I have to weigh in?

Weighing in daily can be very beneficial, but some users may not want to weigh in that often. For those users, we suggest weighing in at least once per week, preferrably on the same day of the week. Try to weigh yourself at a consistent time of day, such as in the morning before eating or showering. Users will be charged a fee of $1 USD for every 14 days that pass without weighing in. Funds from these missed weigh-ins are strategically distributed to users who are weighing in regularly.

When can I cash out?

You can cash out once you've earned at least 80% of your available funds. Cashing out will reset your earnings balance, but you can still earn the remaining funds by continuing to weigh in and make progress. You can also raise new investments at any time.

How does Thinvested make money?

We only make money when individuals or organizations invest in you, so we're highly motivated to help make that happen. Our fee is 10% of the amount invested. For example, if your local gym is offering a $100 investment as an incentive to become a member, then we would charge the gym $110. The $10 fee would be used to pay credit card processing fees, maintain and improve our software, and help us grow Thinvested.

What methods do you recommend for weight loss?

The simplest (yet hardest) approach is oftentimes the right one. For most people, this will mean making permanant changes to your diet and increasing your level of physical activity. Apps like MyFitnessPal can be very helpful for monitoring your diet.
