Real-time self-weighing intervention for weight management. DESRIPTION: Obesity is a serious public health problem that has major implications for longevity, quality of life and healthcare costs (Flegal, Kit, Orpana, & Graubard, 2013). Self-monitoring is one of the effective intervention of behavioral treatment for weight loss (Acharya et al., 2009; Burke, Wang, & Sevick, 2011). It is a method of systematic self- observation and recording of target behaviors with the goal of increasing self-awareness (Wilde & Garvin, 2007). Self-weighing has also been recommended as part of the AHA/ACC/TOS Guidelines for Managing Overweight and Obesity in Adults from the National Heart, Lung, and Blood Institute (Jensen et al., 2014). Recent studies have provided evidences that regular self-weighing has been positively associated with weight loss with no negative psychological outcomes (Kong et al., 2012; VanWormer et al, 2009; Welsh, Sherwood, VanWormer, Hotop, & Jeffery, 2009). Albeit, studies have reported that increasing the frequency of self-weighing has better outcomes. (Lally, Chipperfield, & Wardle, 2008; VanWormer, Linde, Harnack, Stovitz, & Jeffery, 2012; Welsh et al., 2009; Wing et al, 2007). Nevertheless, the frequency or dose of self-weighing for successful outcome is still unknown (Zheng et al, 2015).

Invention concept: This invention is designed to manage a person's weight by real-time self-weighing intervention. See figure 1. 1. There is at least one or few weight/load/pressure sensors in the soles of the footwear which are calibrated to measure the subject's weight. These weight sensors can be easily adapted to a different footwear conveniently by the subject.

2. The measurement values are transferred to the "mobile application" in the mobile device of the subject via Bluetooth / wireless technology.

3. The "mobile application" will store the data and display the real-time weight as well as past recorded body weigh values. The body weight information is further analyzed by the "mobile application" using statistics. The body weight information can be displayed using graphs, charts, tables etc. for comphrensive understanding of the user.

4. The weight data can also be used to compute other health data like Body mass index (BMI) and other such parameters which uses body weight for calculations like total body fat, lean body mass, etc.

5. The data can be easily transferred to the computer, online, cloud for third party (health personal etc.) for sharing and desired interventions.

6. The invention will allow measurement of body weight over extended period of time (over years) as desired/required by the user.

7. Since the weight measuring system is easily transferrable to a new footwear, the system is not restricted to be used in any particular footwear in any manner.

8. The user is free to choose and use the invention in any kind of footwear. 9. Since, this intervention is for weight management it is not merely to reduce weight. This intervention can also be used to gain, maintain or lose weight as desired by the subject. 10. This invention can provide real-time weight of the subject. So, situations which require real-time weight measurement of humans, animals are covered in scope of this invention.
