Hope for Dramatic, Permanent Weight Loss. One intervention that Kevin and Juen do not talk about in their paper is a change in the timing of eating as an intervention, whether that means a short eating window within each day or some use of longer fasts (periods of time without eating but still drinking water). What they do is provide ample reason why interventions short of changing the time pattern of one s eating have such a tough time delivering permanent weight loss. Here is their conclusion: In addition to the long-term feedback control of energy intake mediated by homeostatic signals related to body weight and composition, eating behavior is also strongly influenced by social and environmental influences in conjunction with learned eating habits.73,74 While previous conceptions of the set point model were thought to be incompatible with non-homeostatic influences on food intake and body weight,72 such effects can be naturally incorporated by altering the position or slope of the energy intake line depicted in Figure 3A and the defended body weight will be adjusted accordingly. Unfortunately, we do not yet know the quantitative effects of non-homeostatic influences on the set point model, but there is likely to be a wide degree of individual variation. Some people may experience substantial changes in the energy intake, along with correspondingly large weight changes, whereas others will be more resistant. Re-engineering the social and food environments may facilitate shifts in the energy intake line, but losing weight and keeping it off using willpower alone to reduce energy intake is difficult because considerable effort is required to persistently resist the physiological adaptations that act to increase appetite and suppress energy expenditure. I want to focus attention on the hypothesis that one of the most important aspects of the social and food environment is our customs about the timing of eating: the idea that it is normal to have three meals a day, every day, with snacking being OK. Question that social norm, and there is hope for dramatic,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
