The following drawings show generally, by way of example, but not by way of limitation, various examples discussed in the present disclosure. In the drawings:
Many adults struggle with weight throughout their lives, and, though many have been successful in managing weight through exercise, a larger number of people have been unable to achieve and sustain weight loss via exercise. Step-count targets that can be expected to produce predictable changes in body weight may vastly increase the number of people who are able to successfully manage weight over their adult lives.
Common activity targets are not specific to the individual (e.g., accumulate 10,000 steps/day, expend 1,500 kcals in physical activity each week, or accumulate 420 min of moderate intensity physical activity each week), and, importantly, such targets do not take into account key influences of appetite and energy intake. The systems and methods described herein may address one or more of these shortcomings by leveraging a model (e.g., recommendation algorithm) that is customized based on body fat mass. The systems and methods described herein may address one or more of these shortcomings by determining physical activity levels, such as step count targets, that are individualized, and that account for current body fat mass and target body fat mass, as well as fat-free mass, which is a key determinant of appetite and energy intake.
A method for customized activity level recommendations is described herein. The method may include receiving via an interface, at least one body health indicator associated with a user. The method may further include determining, based at least on the body health indicator, a fat mass metric of the user and a weight/body fatness target of the user. The method may then determine, based on at least the fat mass metric and using a recommendation algorithm comprising a set of rules, a custom physical activity threshold for the user; and output an indication of the custom physical activity threshold.
The at least one body health indicator may be a user's sex, body mass, body fat mass, fat-free mass, body fatness percentage, visceral fat mass, total cholesterol level, high-density lipoprotein cholesterol level, low-density lipoprotein cholesterol level, insulin level, glucose level, triglyceride level, glycosylated hemoglobin level, a cardiometabolic risk factor, an energy intake, an energy expenditure or combinations thereof. The at least one body health may be a user's target body mass, target body fat mass, target fat-free mass, target body fatness percentage, target visceral fat mass, target total cholesterol level, target high-density lipoprotein cholesterol level, target low-density lipoprotein cholesterol level, target insulin level, target glucose level, target triglyceride level, target glycosylated hemoglobin level, target cardiometabolic risk factor, target energy intake, or target energy expenditure or some combination thereof.
The custom physical activity threshold comprises a number of steps taken per day. The custom physical activity threshold comprises a number of steps taken per day per unit of body fat mass, and based thereon, a total daily step count.
The interface may be an activity tracking device. The activity tracking device may incorporate the systems and methods described herein to assist users with selecting a physical activity level that may yield a targeted change in weight/body composition.
The method may include using regression modeling to predict body fatness from daily step counts. The prevalence of overweight and obesity among adults in the U.S. continues to rise, and the associated public health consequences are costly and severe. Excess body fatness is independently associated with increased rates of diabetes, hypertension, dyslipidemia, coronary heart disease, and other chronic conditions. In addition, it is estimated that approximately 34% of U.S. adults have metabolic syndrome, a condition characterized by a combination of central obesity, dyslipidemia, glucose intolerance, and hypertension. Furthermore, recent research shows that, although overall cancer diagnoses and mortality rates in the US are declining, obesity-related cancers are on the rise. A persistent increase in the prevalence of obesity among adults has continued uninterrupted for 40 years, increasing from approximately 14% in 1980 to over 40% today, in spite of myriad efforts to arrest it. Projection of recent trends has led to the troubling prediction that prevalence of adults diagnosed with type 2 diabetes will more than double by 2060.
While the causes of increasing obesity and its comorbidities (e.g., cardiometabolic risk [CMR] factors) are multifactorial, in basic terms, increasing numbers of adults are now exhibiting a chronic energy surplus — that is, a state in which energy intake via diet is consistently greater than the total energy expended (the sum of energy expended in resting metabolism, physical activity, and diet-induced thermogenesis). Numerous research efforts have been undertaken to identify factors that have changed since 1980 that contribute to this epidemic, with widely varying conclusions. Several studies have reported concurrent reductions in various forms of physical activity over the same time, suggesting that diminishing amounts of physical activity are contributing to the increasing prevalence of overweight and obesity. However, although the importance of physical activity (PA) in weight management is apparent in that most weight management guidelines include recommendations for PA, the influence of PA/exercise in weight control interventions is often trivial, and several recently published reviews have concluded that PA contributes little to weight management interventions relative to dietary restriction. While energy balance, and factors that influence it, are complex, it is apparent that many PA/exercise interventions for weight management are insufficient to induce a sustained energy deficit.
Overweight and obesity have been mechanistically linked to type 2 diabetes, cardiovascular disease, and several forms of cancer. Several CMR factors are associated with excess body fatness (e.g., insulin resistance, plasma lipids), as reflected in the diagnostic criteria for metabolic syndrome (abdominal obesity, hypertension, dyslipidemia, and elevated plasma glucose). Understanding variables that are influential of body fatness and CMR profiles is, therefore, of increasing importance. The present disclosure relates to using current and target body weight and composition to develop a step count target that will result in predictable changes in body weight and body fat percentage over several months while eating ad libitum.
A study was carried out at a university. Participants were recruited from among a university community (faculty, staff, students, and nearby residents) in the southeast U.S. via email and posted announcements. The primary inclusion criterion was age (between 19-40 years old), while exclusion criteria included the presence of any diagnosed chronic disease, current involvement in commercial weight management program, and being on prescription medications other than birth control. After providing informed consent, participants made an appointment to arrive to the exercise physiology laboratory between 6:00 a.m. and 9:00 a.m. in a fasted condition (no food or beverage except water for 10-12 hours prior to arrival). They were asked to avoid vigorous exercise on the day prior to laboratory appointments. A total of 34 adults made a laboratory visit in which height, weight, body composition, and cardiometabolic risk factors were quantified. Participants wore accelerometers for 21-28 days, then returned to the laboratory for a second body composition assessment. Changes in weight and body composition were used to quantify energy balance, and data derived from accelerometers provided markers of physical activity and sedentariness.
Of the markers of physical activity measured, daily step counts expressed relative to fat mass was most strongly and consistently associated with body fatness and cardiometabolic risk status. Step counts expressed relative to fat mass were strongly associated with body composition and cardiometabolic risk in adults eating ad libitum.
The initial target was to recruit a total of 40 participants (20 men and 20 women), as a previous pilot study resulted in a strong inverse relationship between steps expressed relative to FM (STEPS·kg FM−1·day−1) and body fatness in men (n=12, r=−0.90) and women (n=34, r=−0.73). To achieve a correlational power of 0.90 (p=0.05), assuming a Pearson r correlation of 0.73, would require n=15; therefore, the systems and methods described herein targeted n=20 men, and n=20 women.
Urine samples were collected, and urine specific gravity was measured to provide an indication of hydration status. Height and weight were measured on a medical-grade scale and stadiometer (Tanita Corporation of America, Arlington Heights, Ill.). Bioelectric impedance analysis (BIA) was then conducted on an InBody 770 analyzer (Cerritos, Calif.). Thereafter, participants underwent a dual-energy x-ray absorptiometry (DEXA) scan to assess body fatness and fat distribution. The assessment was conducted in accordance with manufacturer's (iDXA, General Electric, Inc., Madison, Wis.) guidelines to quantify body fat percentage (BF), visceral fat area (VFA), fat mass (FM), and fat-free mass (FFM). VFA measurement was obtained by the iDXA software (enCORE version 13.60) using default android region boundaries.
Thereafter, participants provided a finger-stick blood sample. Fasting plasma lipids (total cholesterol [TC], high-density lipoprotein cholesterol [HDL], low-density lipoprotein cholesterol [LDL], and triglycerides [TG]) were measured using a Cholestech LDX analyzer (Alere, Orlando, Fla.). Plasma glucose (GLU) was measured in duplicate using a Medtronic Contour glucometer (Bayer, Pittsburgh, Pa.), with the average of the two readings recorded. Glycosylated hemoglobin (HbA1c) was also measured using finger-stick blood sample with a Siemens DCA Vantage (Malvern, Pa.) analyzer. In addition, blood was collected on Whatman 903 Protein Saver Cards (GE Healthcare Ltd., Cardiff, CF UK) and allowed to dry, and dry blood spots were analyzed later for plasma insulin (INS). Quantitative check index for insulin sensitivity (QUICKI) was calculated using fasting GLU and INS levels.
Participants were then provided instructions for the wearing of accelerometers. Each participant was provided with an Actigraph GT3x (Pensacola, Fla.) accelerometer and a wrist strap, and were instructed to wear the device for all of their waking hours, with the exception of time spent bathing or showering. All accelerometers were initialized using information describing the participant (e.g., age, height, weight, and sex of the participant). Accelerometers were worn on the non-dominant wrist, and participants were encouraged to live and eat normally, and to not alter their behaviors during the course of their involvement in the study. Follow-up appointments were made for 21-28 days later. During the follow-up laboratory visit, urine specific gravity was again measured, weight was measured on the same scale used in the first visit, and BIA and DEXA scans were again conducted. Accelerometers were collected, and data were downloaded using the ActiLife software (version 6.13.3). Activity was assessed in 10-sec epochs, and wear-time analysis was performed. Data derived from participants who wore accelerometers for fewer than an average of 12 hours per day (n=4) were eliminated from further analysis. Estimates of daily step counts, MVPA, and SED were recorded.
Body composition was determined using 4-compartment modeling. Body volume was determined using data derived from DEXA scans, and total body water was derived from BIA assessment. BF was determined as described previously. Energy balance for the study period was determined by quantifying the changes in FM and FFM across the study period, and the total differences were divided by the number of days between laboratory visits to determine the average daily energy balance. Participants were considered to be in a state of energy imbalance if the average daily energy balance showed a surplus or deficit of greater than 1,000 kcal·day−1, and their data were not analyzed (n=3).
All statistical tests (descriptive statistics, Pearson r and Spearman's rho correlations, linear regression, and power regression) were performed using SPSS (IBM, Armonk, N.Y.), Version 26.
A total of 34 participants (19 females, 15 males) completed the study protocol, with average accelerometer wear times of at least 12 hours per day during their involvement while maintaining energy balance. Among those whose data were included, there was no correlation between accelerometer wear time and any expression of STEPS, and there were no differences in body composition, fat-free mass, FM, or weight between the two assessments. INS was not measured in one man as a result of a vaso-vagal response to the finger stick. In addition, HbA1c was not measured in two women due to reportedly low hemoglobin levels, and LDL and TG were not able to be measured in two men and two women due to range limitations of the measuring device (briefly, if TG are less than 45 mg·dl−1, they cannot be accurately measured, and LDL then cannot be calculated with the Cholestech LDX). Urine specific gravity (USG) was normal (between 1.002 and 1.030) in all participants prior to each assessment. Descriptive data are provided in Table 1.
A key independent variable in this study was step count expressed relative to fat mass (STEPS·kg FM−1·day−1), and this variable was not normally distributed (significant Shapiro/Wilk test). Therefore, relationships with this indicator of physical activity were determined using the Spearman's rho.
Physical Activity and Body Fatness
Body fatness was strongly associated with several markers of physical activity in men and women, particularly when physical activity was expressed relative to FM (see Table 2).
STEPS (STEPS·kg FM−1·day −1) were inversely correlated with percent body fat, fat mass (FM), and visceral fat mass (VFM). STEPS was the strongest predictor of body fatness. Applying a power regression model (see
Physical Activity and Cardiometabolic Risk Factors
Physical activity levels were associated with CMR profiles, particularly when physical activity was expressed relative to FM (see Table 3).
STEPS expressed relative to FM were most consistently correlated with TC:HDL ratio, HDL, QUICKI, and GLU in the full sample, as well as in men and women independently. Power regression analysis showed that STEPS·kg FM−1·day−1 was the best predictor of TC:HDL (R2=0.26 for women, R2=0.52 for men; see
A key finding of this research study was the strong relationship between STEPS expressed relative to FM (e.g., STEPS·FM−1·day−1) and markers of body fatness. While a number of cross-sectional studies have reported inverse relationships between daily step counts and body fatness when STEPS are reported in absolute terms (e.g., STEPS·day−1), results of the current study yielded no such relationship (see Table 2 and
The strength of the relationship between STEPS·FM−1·day−1 and body composition in adults eating ad libitum may be largely explained by recent studies reporting that, of a number of factors that have been shown to transiently influence energy intake, fat-free mass exerts a tonic (that is, constant, stable, in contrast to transience influences like incretins and adipokines) influence on appetite, and is strongly correlated with resting metabolic rate which accounts for over half of the variability in energy intake in adults. As an illustrative example, at any body weight, the dose of PA to achieve energy balance may account for the tonic influence of fat-free mass on appetite and energy intake. Furthermore, given that fat-free mass in an individual is quite stable with daily variations in PA, the tonic influence of fat-free mass on appetite and energy intake would be expected to make it difficult to maintain energy balance or a sustained energy deficit at very low levels of PA, as has been reported in several studies.
This explanation aligns well with the “settling point” model of body weight (see
Expressions of STEPS relative to fat mass appear to account for the influence of each element of the “settling point” model (i.e., energy intake, energy expenditure, and the energy reservoir represented by body fatness). For example (see Table 4), Subject A is a male weighing 80 kg with 25% body fat, and therefore has a lean mass of 60 kg, and a fat mass of 20 kg. Subject B is a male weighing 100 kg with 20% body fat, and has a lean mass of 80 kg and, like Subject A, also has a fat mass of 20 kg. The power regression model resulting from analysis of data from a pilot study (see
In another example wherein two women weigh the same, but have different body compositions, (see Table 5), Subject C accumulates ˜1,332 steps/day more than Subject D, resulting in body fat mass “settling” at 24 vs 28 kg. The additional PA that Subject C accumulates may serve to compensate for the increased appetite and energy intake stimulated by the larger fat-free mass, while also increasing total daily energy expenditure through PA, thereby leading to a lower settling point for body fatness.
While an interventional study was not conducted, the strength of this relationship suggests that it may be possible to prescribe PA specific to current and target body composition to produce predictable changes in body fatness in adults eating ad libitum. For example, in a weight management application, a man weighing 80 kg with 25% body fat possesses 20 kg of fat. Utilizing the results of power regression analysis, BF =2679.5·(STEPS·kg FM−1·day−1)−0.746 results in a predicted STEP count of approximately 526.4 STEPS·kg FM−1·day−1, or about 10,528 STEPS·day−1. Assuming a target body composition of 20% fat, with the FM that he currently possesses, this individual may be prescribed a target of 709.91 STEPS·kg FM−1·day−1 (relative step counts associated with 20% BF), or about 14,199 STEPS·day31 1.
A prescribed dose of PA, and particularly STEP counts, relative to an individual's current fat mass and targeted body composition, may be effective in identifying a PA target to result in a predictable energy deficit. Currently, the American College of Sports Medicine (ACSM) and other professional organizations express recommended exercise doses in absolute terms (e.g., kcals/week, steps/day). For example, ACSM recommends the accumulation of ≥2,000 kcal of exercise per week by those for whom weight loss/management is a priority. Similarly, the National Weight Control Registry has recently recommended the accumulation of 2,500-2,800 kcal of activity per week for weight control. However, as noted previously, a number of studies have reported that PA/exercise produces unpredictable and disappointing results for weight management relative to dietary restrictions, suggesting that the PA interventions were inadequate to induce an energy deficit. Findings suggest that expressions of PA as STEPS relative to FM are capable of predicting body composition, and may be efficacious for prescribing PA for achieving weight management objectives in adults eating ad libitum.
Physical Activity and Cardiometabolic Risk Factors
As reflected in the diagnostic criteria for metabolic syndrome, excess body fatness is linked with unfavorable CMR profiles (e.g., fasting blood glucose, dyslipidemia). However, at any given level of body fatness, CMR status may be improved via increases in PA. The findings of strong associations between expressions of PA and CMR factors are supportive of the capacity for PA to improve CMR status at any given level of body fatness. As shown in Table 6, and in
In summary, step counts expressed relative to FM were strongly predictive of body composition in adults, a finding that suggests that physical activity prescribed based on current and target body composition may be efficacious in yielding predictable changes in body fatness in adults eating ad libitum. Similarly, physical activity expressed relative to FM was strongly predictive of several common markers of CMR, suggesting that levels of CMR factors may be predictably affected by changes in physical activity expressed relative to FM.
The systems and methods described herein utilized accelerometers worn on the non-dominant wrist to record physical activity and step counts. The wrist was chosen instead of the hip because participants were to be wearing the accelerometers for at least 21 days, and many had indicated a reluctance to wear the device on the hip due to appearance, a preference that others have previously reported as well. In addition, while estimates of physical activity energy expenditure were recorded using the Actigraph accelerometers, others have recently reported concerns with validity of energy expenditure estimates derived from these devices. The systems and methods described herein, therefore, limited analysis in this study to STEPS, MVPA, and SED. It is noteworthy, furthermore, that expressions of STEPS were more predictive of CMR and body composition outcomes than estimates of physical activity energy expenditure.
A further study was conducted for the purposes of determining the efficacy of the model reported previously developing daily step count targets that may be expected to produce predictable changes in body weight and body fatness in adults 19-40 years of age eating ad libitum. To date, we have had six participants (29.3±5.7 years old, 166.6±9.2 cm tall), all women, undergo two assessments of body weight and composition. Assessments were separated by three months, and activity trackers (e.g., pedometers were worn daily for those three months. After the first assessment, the model was used to develop a step count target predicted to yield a 7% weight loss, and participants were encouraged to strive to achieve those targets as regularly as possible. Daily step counts were submitted approximately weekly, and participants were provided feedback on how they were doing relative to their targets on two occasions over three months. After three months of pedometer wear, participants underwent assessments of body composition identical to those conducted at baseline, and changes in weight and body fatness were analyzed. In addition, actual step counts (average over previous 4 weeks) were compared with target step counts, and actual step counts were applied to the model to predict body composition.
As shown in Table 7, none of the changes in weight or body fatness were significant at 3-months, though all of the means improved.
Although participants were walking more at 3-months than they were at the onset of the study, they were coming up short of their daily target by an average of ˜1,850 steps per day (see Table 8).
Application of the model to actual step counts resulted in predictions of body fatness that were strongly correlated with actual body composition (see Table 9 and
These results support the efficacy of the model for developing step count targets that, if adhered to, may be expected to result in predictable changes in body weight and composition.
Many operating systems, including Linux, UNIX®, OS/2®, and Windows®, are capable of running many tasks at the same time and are called multitasking operating systems. Multi-tasking is the ability of an operating system to execute more than one executable at the same time. Each executable is running in its own address space, meaning that the executables have no way to share any of their memory. Thus, it is impossible for any program to damage the execution of any of the other programs running on the system. However, the programs have no way to exchange any information except through the operating system (or by reading files stored on the file system).
Multi-process computing is similar to multi-tasking computing, as the terms task and process are often used interchangeably, although some operating systems make a distinction between the two. The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention. The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device.

The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
