Smart Bra – Support for Emotional Eating


A bra that can prevent overeating? Don’t laugh, there are people working on it. True story. A group at the University of Rochester Department of Computer Science are researching a “just-in-time support system for emotional eating”. The researchers conducted user studies and built a prototype with the wearable technology.

The following information is from the report.

RESEARCH APPROACH
Designing a system to provide just-in-time interventions for emotional eating is an ambitious endeavor. Consider the following hypothetical scenario:

Sally has been home from work for a few hours, and she finds herself rather bored. An application on Sally’s mobile phone has also detected that she is bored by reading her physiological state through wearable sensors. Since this mobile application has previously learned that Sally is most susceptible to emotional eating when she is bored, the application provides an intervention to distract Sally and hopefully prevent her from eating at that moment.

From this scenario, we see three key requirements for a just-in-time support system for emotional eating. First, the application has to be aware of the user’s emotional eating
patterns. Does Sally emotionally eat only when she is bored? Second, the system needs to be able to implicitly detect emotions. This involves wearable physiological sensors that are connected to the mobile phone. Implicit detection of emotions would then be possible through machine learning classification, which requires training on large amounts of users’ data.

Finally, it is critical (and perhaps the most challenging) to determine how to intervene. What type of intervention do we design? How often do we intervene? How do we prevent it from becoming an annoyance to the user? Our approach to researching a just-in-time support system for emotional eating was to make strides towards addressing these three requirements. We studied these requirements across three user studies, which have been summarized below.

• First, the application has to be aware of the user’s emotional eating patterns. Does Sally emotionally eat only when she is bored?

• Second, the system needs to be able to implicitly detect emotions. This involves wearable physiological sensors that are connected to the mobile phone. Implicit detection of emotions would then be possible through machine learning classification, which requires training on large amounts of users’ data.

• Finally, it is critical (and perhaps the most challenging) to determine how to intervene. What type of intervention do we design? How often do we intervene? How

Study 1: Gather Emotional Eating Patterns.
We investigated eating behaviors and corresponding emotions of participants by having them self-report their emotions and log their eating patterns using a custom built application called EmoTree. The goal was to understand their emotions associated with eating.

Study 2: Investigate An Intervention Technique.
The purpose of Study 2 was to learn about a particular intervention technique for emotional eating. We prototyped implicit intervention by triggering an intervention based on self reported ratings of emotions. This allowed us to gather early feedback about interventions before implementing an automatic system. Are users aided by the intervention? Was the intervention sent at the appropriate time? What other types of interventions would interest users?

Study 3: Emotion Detection with Wearables.
This work was a first step in building an automatic system. We investigated the feasibility of using physiological sensor data, combined with machine learning, to automatically detect emotions in a mobile system. We also present the design of our wearable system.

The hypothetical feedback, whether from a social network, a close friend, or pre-recorded messages, served as a health intervention to encourage the person to be more active or consume less food.


Behavior modification in health is difficult, as habitual behaviors are extremely well-learned, by definition. This research is focused on building a persuasive system for behavior modification around emotional eating. In this paper, we make strides towards building a just-in-time support system for emotional eating in three user studies. The first two studies involved participants using a custom mobile phone application for tracking emotions, food, and receiving interventions. We found lots of individual differences in emotional eating behaviors and that most participants wanted personalized interventions, rather than a pre-determined intervention. Finally, we also designed a novel, wearable sensor system for detecting emotions using a machine learning approach. This system consisted of physiological sensors which were placed into women’s brassieres. We tested the sensing system and found positive results for emotion detection in this mobile, wearable system.

“Big Game” Eating Extravaganza with Exercise Equivalents


Did you know that this weekend’s “Big Game” is the second biggest day of food consumption in the United States? Second only to Thanksgiving. Charles Platkin, PhD, MPH, a professor at the CUNY School of Public Health at Hunter College in New York City and editor of DietDetective.com demonstrates how much you would need to do to burn off typical “Big Game” snacks. For instance, you would have to run 49 football fields to burn off just two handfuls of potato chips or do “the wave” 6480 times to burn off 6 Buffalo Wild Wings Dipped In Ranch.

“Big Game” Calorie Costs in Exercise
City University of New York School of Public Health at HUNTER College Professor Shows Big Game Activities to Burn off Foods You Just Ate

The Annual 2013 DietDetective.com “Big Game” Eating Extravaganza with Exercise Equivalents

New York, NY (January 29, 2013) –
The “Big Game” has become much more than a football game: It’s the second biggest day for food consumption in the United States after Thanksgiving. So, to choose the most splurgeworthy foods, here are the exercise equivalents* for some of your favorite football snacks from Charles Platkin, PhD, MPH, public health advocate, editor of DietDetective.com and Distinguished Lecturer (professor) at the CUNY School of Public Health at HUNTER College. The idea is to use exercise equivalents to provide a reference for calories.

HANDFUL OF PITA CHIPS, EACH WITH ARTICHOKE DIP = RUNNING 141 FOOTBALL FIELDS
Each chip is 13 calories, plus just 1 tablespoon, probably just about a chips worth, of dip is 80 calories.

Diet Pro: Make your own 100 percent whole-wheat pita chips, and use salsa instead of the artichoke dip. There are many different kinds of salsa. They’re good, and they’re only 15 calories per tablespoon.

FOUR (4) DOMINOS STUFFED CHEESY BACON & JALAPENO BREADSTICKS = 193 TOUCHDOWN DANCES IN THE END ZONE
While the stuffed cheese bread is probably very tasty, with all that fat it’s also a calorie killer at 160 calories per piece, or 640 calories for four.

Diet Pro: You can toast 100 percent whole-wheat pita bread with butter spray and Parmesan cheese.

TWO (2) SLICES OF DOMINOS BACON CHEESEBURGER FEAST HAND-TOSSED SPECIALTY PIZZA (16 inches) = 209 MINUTES PERFORMING IN A MARCHING BAND
Pizza AND a cheeseburger what will they think of next? Each slice is 490 calories, but it is hand tossed.

Diet Pro: Try thin-crust pizza, and if you really want to be super healthy, how about getting pizza without the cheese just add your own Parmesan.

HALF (1/2) OF A WHITE CASTLE CRAVE CASE WITH CHEESE = FACE PAINTING 111 WILD FANS
These are sliders with cheese. Each slider is 170 calories. That’s 2,550 calories for 15, but they’re not very large, and there are 30 in a case.

Diet Pro: How about having just one or two? Make your own burgers white meat turkey burgers if you really want to be super healthy, or at the very least very lean ground meat.

THREE (3) SIERRA NEVADA BIGFOOT BEERS = 211 MINUTES OF COACHING FOOTBALL
There are some high-calorie beers out there, and this is one of the highest.

Diet Pro: Unless you love Sierra Nevada and realize the calories, your best bet is a regular beer OR, even better, one of those micro-light beers. The best would be Beck’s Premier Light at only 64 calories per 12-ounce bottle or MGD Light, also 64 calories. Michelob Ultra and Natural Light have 95, or you can go very low with Budweiser Select for 55. Sample a few light beers before the game to see which ones you prefer.

ONE (1) SLOPPY JOE = 59 MINUTES OF CLIMBING THE STADIUM STAIRS
This is a Tex-Mex creation that includes fatty ground beef, sugar, ketchup and even flour. Sloppy Joes have more than 500 calories with the bun (about 150 calories).

Diet Pro: Use lean ground beef and try a low-calorie sauce (without sugar). It will still taste great. Also, add veggies (onions, peppers, broccoli all chopped up) to the meat to lower overall calories and increase health benefits.

SIX (6) TRADITIONAL HAND-SPUN BUFFALO WILD WINGS DIPPED IN RANCH DRESSING = DOING “THE WAVE” 6,480 TIMES
Stand up, wave your hand and be counted 6,480 times. Six wings from Buffalo Wild Wings have 990 calories. Then add about two servings of ranch dressing at 170 calories each for a total of 340 calories. That’s 1,330 calories if you have only a small dip of dressing per wing.

Diet Pro: You can certainly make your own chicken wings. Go skinless and bake instead of deep frying them.

TWO (2) HANDFULS OF CHEETOS JUMBO PUFFS = 30 MINUTES OF PLAYING PROFESSIONAL FOOTBALL
The only problem is that, according to The Wall Street Journal, there are only about 11 minutes of actual ball playing in a football game. That means you need to play almost three games of professional football to burn off two handfuls of Cheetos. Keep in mind, that’s 320 calories for about 2 ounces yes, only 2 ounces.

Diet Pro: How about making your own popcorn? Sprinkle it with Parmesan cheese and spray it with butter spray.

ONE (1) HANDFUL OF TRAIL MIX = 49 TOUCHDOWN DANCES IN THE END ZONE
Keep in mind, nuts and chocolate have about 160 calories per ounce, which is not bad if you don’t take five handfuls before you’ve even noticed.

Diet Pro: Try having ONLY nuts. Nuts are healthy, but they’re very high in calories, so don’t keep a huge bowl in front of you. And try to eat them one at a time meaning don’t shove an entire handful into your mouth all at once.

BUBBA GUMP JAMBALAYA = 375 MINUTES OF PREPARING, COOKING, SERVING AND CLEANING UP AFTER THE SUPER BOWL PARTY
That’s more than six hours of cooking, preparing and cleaning. Yes, Bubba Gump is a chain, and the Jambalaya has 1,100 calories. Jambalaya is typically made with chicken, shrimp and andouille sausage sauté with peppers, onions, rice and spicy sauce.

Diet Pro: Make a healthy jambalaya with boneless chicken breast and brown rice. Thats the way to go.

OUTBACK BABY BACK RIBS, FULL ORDER = 123 MINUTES OF TEAM PRACTICE AND CONDITIONING
Ribs are fatty, and the sauce is sugary. For the record, Outback Baby Back ribs are 1,156 calories.

Diet Pro: Try making them yourself, and trim all visible fat before and after cooking. Also, instead of coating your ribs with an excessive amount of sauce beforehand, partially cook them loaded with seasonings, brush them lightly with the sauce, and then finish cooking.

FOUR (4) BACON-WRAPPED SMOKIES = 156 MINUTES BEING THE TEAM MASCOT
Little sausages wrapped in bacon popping just four of those in your mouth will cost you 156 minutes of jumping around and acting a bit foolish (the good news is you’ll be wearing a costume). The bacon alone, (without the sausage and brown sugar) is more than 80 calories, for a total of more than 160 calories per appetizer. Four of them go down easy for 640 calories.

Diet Pro: If you need to eat some type of bacon-wrapped hors doeuvres, go with Applegate Farms Organic Hickory Smoked Uncured Turkey Bacon. Its only 35 calories per slice. Hebrew National Beef Franks in a Blanket are 60 calories each.

THREE (3) PEPSIS = 57 MINUTES OF DANCING TO BEYONCE DURING THE SUPER BOWL HALFTIME PERFORMANCE
Each 12-ounce can is 100 calories. So to burn off just three Pepsis you need to dance for more than an hour to a Beyoncé song. Have you heard her music? Have you danced for an hour straight?

Diet Pro: Water, flavored seltzer, unsweetened ice tea there are so many low- or no-calorie drinks.
