The purpose of this study is to explore the effects of an intervention designed to help increase physical activity and decrease screen time.
There are limited evidence-based treatments for adolescents with binge eating and fewer specifically targeting adolescents with both binge eating and overweight/obesity. The existing research for adolescents with overweight/obesity and loss of control (LOC) eating supports a stepped-care model of treatment in which enhanced behavioral weight loss treatment is the first line of treatment followed by more intensive therapeutic treatment for individuals with remaining emotional eating difficulties. Thus, in this proposed study, the investigators will systematically develop a stepped-care protocol and manualized interventions for adolescents with LOC and binge eating behaviors. The investigators will then evaluate the feasibility and acceptability of the interventions in a pilot trial and gather preliminary outcome data to inform development of a subsequent randomized controlled trial.
This study is a randomized, adaptive, parallel arm study. The treatment group will receive the Elira wearable patch system and provided instructions for use and advised to follow a 1200 calorie diet. The control group will be asked to follow a 12 calorie diet only. Each group will be followed for 12 weeks. Total body weight loss will be measured as well as appetite changes. Safety data will be collected throughout the study period. Safety and effectiveness will be determined based on differences between the groups.
This study is investigating the impact of a skills training program in stimulus control of meals and snacks on zBMI. Participants will be randomized to a standard family-based obesity treatment intervention with education on child health or a standard family-based obesity treatment intervention with experiential learning about meal stimulus control strategies.
The purpose of this study is to evaluate the effect of dietary fat on satiety (the experience of fullness between one meal and the next) and energy metabolism over an extended period of time (chronic effects). How dietary fat sources affect satiety, appetite and energy use is unclear. The investigators will use a controlled setting for the studies. They want to know if the source of dietary fat alters satiety, satiety hormones, and energy expenditure responses after consuming different diets.
In order to study the effectiveness of personalized healthcare intervention for lifestyle-related diseases, investigators designed this study using mobile application and clinical feedback coaching.
There is an ongoing and worsening problem with obesity in the developed, and much of the developing world. Although it has long been realized that Western diets that are rich in sugar and fat play an important role in this, it has only recently been realized that exposure to these diets, particularly in childhood, can damage the part of the brain that determines how much fat there is in the body. The result of this damage is that the so-called "set-point" for fat in this part of the brain is pushed upwards. There is a lot of evidence from animals that activating the brain's balance (vestibular) system pushes this set-point for fat downwards to cause fat loss, probably because this tricks the brain into thinking that the animal is more physically active. The aim of this study is to see whether the same effect can be triggered in humans by non-invasively stimulating the vestibular system with a small electrical current through the skin behind their ears.
Rationale: The microbial composition in the small intestine (SI) differs largely from the composition in feces. Many physiological processes related to health, such as immunoregulation and metabolic programming, mainly take place in the SI. Therefore, the SI, from a microbiota perspective, is as relevant as the large intestine. There are indications that microbiota composition is different in lean and obese subjects, and is related to insulin resistance. However, these indications are mainly based on the analysis of fecal samples. Therefore, analysis of the microbiota composition in the more proximal part of the gastrointestinal (GI) tract may provide new insights into the microbial species that are involved or related to metabolic homeostasis at that location. The IntelliCap® CR system offers a minimally invasive tool that is able to collect reliable samples in the SI, as was shown by NIZO in a clinical validation study. The main aim of the current study is to explore and compare the upper GI microbiota composition in lean and obese subjects, in order to generate new leads for development of products that may target the upper GI microbiota community or specific species thereof, which may impact the maintenance of metabolic homeostasis. This may provide new opportunities for the treatment, reduction or prevention of overweight and/or obesity or insulin resistance.
The purpose of the registry was to observe the safety and effectiveness outcomes for subjects treated with the EndoBarrier in the post market setting where the product had Conformité Européene (CE mark) regulatory approval and in accordance to the approved Indication For Use.
The study will take place at a cafe managed by university dining services and is located in a university building adjacent to the psychology building. The cafe sells sugar-sweetened beverages and a variety of diet drinks. The campus dining services and the manager of the cafe have given investigators permission to "tax" their sugar sweetened beverages and will provide their sales data for a 12 week period. The investigators will introduce four arms to the experiment. One arm will be baseline data where business 'as usual' will be conducted and no price increases will be implemented on SSBs. In the general tax condition the investigators will introduce a 3 cent/ounce tax on the five SSB flavors the café offers. In the Pre-K tax condition the investigators will institute a 3 cent/ounce tax but will label the tax as proceeds going to Pre-K education. This is designed after the Philadelphia tax that was recently passed where funds were earmarked to benefit childhood education. In the childhood healthy eating program condition the investigators will institute a 3 cent/ounce tax but will label the tax as proceeds going toward childhood healthy eating programs. In all tax conditions the firm will keep the proceeds, but the research team will make a donation to a Pre-K education non-profit and a childhood healthy eating non-profit of the amount generated by the tax during the study period. Each experimental arm will run for 3 weeks total (for a total study period of 12 weeks). The conditions will alternate by week (i.e., week 1: business as usual; week 2: general tax; week 3: pre-K tax; week 4: childhood healthy eating tax; week 5: business as usual, etc). A research assistant will visit the café each week to make any necessary changes to signs that will label the drinks. The investigators will change the signage of the drinks in the cooler during the study period. For the baseline period there will be no changes to the signs made. Currently all beverages are labeled with their name and cost (e.g., Pepsi, $1.89). In the tax conditions the investigators will change the price of the drink (3 cents/ounce) and add a line notifying consumers of the soda 'surcharge' (note "surcharge" will be used in the study because no tax was actually passed by the local government). An example of this sign would be 'Pepsi, $2.29, includes 40 cent sugary drink surcharge.' In the Pre-K tax condition an added line will say, "Pepsi, $2.29, includes a 40 cent sugar sweetened beverage surcharge. Proceeds benefit Pre-K education." In the childhood healthy eating programs condition the text will say, "Pepsi, $2.29, includes a 40 cent sugary drink surcharge. Proceeds benefit Childhood Healthy Eating programs."
