Within this broader study, we conducted a qualitative investigation with a sub-sample of participants, to address the question: what factors may influence individual experiences and outcomes in the SkiM weight management programme?
By enhancing our understanding of why some people did better than others, we hoped to identify potential improvements in the intervention. This paper reports that investigation, and follows the guidelines provided in the COREQ consolidated criteria for reporting qualitative studies [ 17 ].
The completed checklist is provided in Additional file 1. All participants gave written informed consent. Recruitment used two routes: i letters sent by General Practitioners GPs to a random sample of their patients meeting age and BMI criteria, or ii verbal invitations issued by the staff of National Health Service NHS healthy lifestyle hubs to individuals who had been referred by their GPs for signposting to weight management services.
The main study began with participants, all of whom were interviewed at baseline, which enabled sub-sampling for follow-up interviews based on weight loss during the programme.
After the intervention, 36 participants were purposively selected for the qualitative sub-study, ensuring inclusion of those who were successful in initial weight loss and those who were not, men and women, and the age range of the full sample.
Some participants withdrew from the main study before the intervention ended and were not included in the sampling frame, but all of those invited to follow-up interviews agreed to participate. Demographic, weight, and programme attendance data were collected as part of the main study collection and analysis procedures are reported elsewhere: Greaves et al.
Baseline interviews were conducted by either LP or SvB see Additional file 1 for interviewer characteristics and training. All follow-up interviews were conducted by LP. They were audio-recorded digitally and transcribed verbatim for analysis, and field notes were made by the interviewer.
All interviews were semi-structured, using topic guides formulated specifically for this study to address the aims of the broader feasibility study and of this nested investigation. At baseline, participants were asked about their weight management history and reasons for joining, and expectations of, the programme.
These data were used to inform subsequent development of the programme. Follow-up interviews focussed on their weight management experience, although the second interview was also concerned with evaluation of the feasibility and acceptability of the SkiM programme which is reported elsewhere by the authors; Greaves et al.
Additional file 2 provides the full topic guides, but the main questions relating to this study were:. Thematic analysis was selected because of its flexibility: it can facilitate development of both structured descriptions and conceptual models, while identifying areas of commonality and divergence across a sample.
These features were important for the analysis, because its purpose was to describe the experiences of a diverse group of individuals, and to identify potential mechanisms linking them to long term weight outcomes. We adopted a critical realist approach, which posits that it is possible to develop explanatory accounts and models of human behaviour, although these will be situation-dependent and may capture only a small part of the underlying reality [ 20 ].
We used Nvivo v11 software QSR International, Australia to assist the analysis. Only the accounts of the 36 participants sampled from the main study were included in the this analysis, which was conducted by LP and SvB.
Analysis began with repeated reading of the transcripts and generation of descriptive codes. After independent coding of five baseline transcripts, the researchers met to discuss and iteratively develop a coding framework for analysis of the remaining transcripts.
The analysts then worked together to rearrange and combine the coded concepts into a set of descriptive themes that encompassed the issues most salient to the research question. Transcripts from the second cohort of participants were then incorporated into the analysis.
This entailed reading them in temporal sequence for each participant, considering whether the existing coding and thematic frameworks adequately described their content, and specifically looking for examples of congruence or dissonance with themes developed from the first cohort analysis.
This process enabled a judgement on whether thematic saturation had been achieved. In the final stage of analysis, a set of interpretive themes were developed and an explanatory model was created to link them.
The model aimed to provide an explanatory framework linking individual behaviours and experiences to outcomes. The coherence and explanatory power of the model was checked through re-reading transcripts, consulting post-interview field notes and memos created during the analysis, and discussion between the authors.
This led to further development of the model to the form presented in this paper. Table 1 provides data on the number and duration of interviews conducted at each study stage. One recording from the baseline interviews and two from the final interviews were unavailable for transcription due to recorder malfunction, leaving transcripts for analysis.
Participant group-level demographics and weight change data are provided in Table 2 ; individualised data is available in Additional file 3. Our analysis produced several overarching themes that we linked together through a model of in-the-moment decision-making Fig.
The themes were: 1 encountering and managing key situations; 2 the impact of emotion; 3 the source of control; 4 personal values; and 5 acquiring knowledge and skills. In the following sections, each interpretive theme is presented, along with descriptive sub-themes derived during the analysis which are highlighted in bold.
In many accounts, participants described key incidents or situations which, individually or through repetition, significantly impacted their weight management experience and outcomes. Many spoke of facing particular situations that presented strong challenges to the behavioural changes they were making to lose weight.
These situations were often set up by external factors such as social influenceswork-patterns or exposure to food-rich environments. They could also be attributed to internal experiences such as emotional arousalboredom or fatigue.
Often, key situations evoked a habitual responsebuilt up over time, in which an existing obesogenic behaviour automatically followed a regularly encountered cue. These habitual responses, and the cues that evoked them, were identified by many participants as significant influences on their eating behavioural decisions.
The need to break unhealthy habitual responses in key situations was commonly recognised, and those who were most successful spoke of their success in doing so. For instance, they became more aware of these situations and developed strategies to deal with them.
These included avoiding the situation, managing the external influences operating at the time, or engaging in an inner conversation to encourage a new, healthier response.
It was more about a strategy to stop yourself doing the things that you were doing when you were in the moment kind of thing.
To stop and think about it for a minute and relax an breathing and just putting it off, and then you have a glass of water, you put it off for ten minutes you probably forget about it.
Key situations could therefore be seen as moments in which conscious or unconscious behavioural decisions are triggered. Success in weight management involved bringing decision-making into consciousness is such situations to manage them more effectively. Some of those who were successful in the longer term spoke of their new responses to key situations eventually becoming habitual.
The majority of participants said that their obesogenic behaviours were strongly influenced by their emotional state, and particularly by a desire to alleviate negative feelings or create or enhance positive ones. A number of key situations were identified as influencing decisions about what and when to consume.
Comfort-eating or drinking was commonly reported, mostly by women but also by some men, although some people said they tended to eat less when they were feeling down. Many also spoke of eating for pleasureor of consuming more in situations where they were feeling happy.
Emotions play a part in what you do and what you eat. And it would be a half packet of biscuits, not just two or three. Some used strategies suggested in the intervention to weaken the link between their emotional state and choosing to eat unhealthily, for instance by deriving equal pleasure from a smaller portion or from healthier food, or by selecting an alternative source of comfort.
Being able to walk up a hill without getting breathless. However, many felt unable even to attempt this or said they had tried and failed, because nothing else could satisfy the emotional need at the time.
Some said they could not think clearly and choose alternative behaviours in situations of strong emotion; others portrayed the decision as both automatic and consciously-willed. When I get too overwhelmed with things, I lose that capacity to think straight.
Emotional responses to progress, or the lack of it, in weight management were also seen by many as driving subsequent behavioural decisions.

| Farewell to the 3,Calorie Rule | In an October study published in the journal Obesity , researchers examined what happened to 14 of the contestants on the Biggest Loser weight loss reality show, six years after they attempted to slim down for TV. They again found there was no relationship between physical activity and weight loss during the active weight loss of the show. But they also found there was a strong relationship between exercise and keeping weight off. The study participants who managed to maintain their weight loss after six years got 80 minutes of moderate exercise per day or 35 minutes of daily vigorous exercise. The benefits of exercise are real. And stories about people who have lost a tremendous amount of weight by hitting the treadmill abound. But the bulk of the evidence tells a less impressive story. Consider this review of exercise intervention studies, published in It found that after 20 weeks, weight loss was less than expected, and that "the amount of exercise energy expenditure had no correlation with weight loss in these longer studies. To explore the effects of more exercise on weight, researchers have followed everybody from people training for marathons to sedentary young twins to post-menopausal overweight and obese women who ramp up their physical activity through running, cycling, or personal training sessions. Most people in these studies typically only lost a few pounds at best, even under highly controlled scenarios where their diets were kept constant. Other meta-analyses, which looked at a bunch of exercise studies, have come to similarly lackluster conclusions about exercise for losing weight. This Cochrane Review of all the best available evidence on exercise for weight loss found that physical activity alone led to only modest reductions. Ditto for another review published in University of Alabama obesity researcher David Allison sums up the research this way: Adding physical activity has a very modest effect on weight loss — "a lesser effect than you'd mathematically predict," he said. We've long thought of weight loss in simple "calories in, calories out" terms. In a much-cited study, researcher Max Wishnofsky outlined a rule that many organizations — from the Mayo Clinic to Livestrong — still use to predict weight loss: A pound of human fat represents about 3, calories; therefore, cutting calories per day, through diet or physical activity, results in about a pound of weight loss per week. Similarly, adding calories a day results in a weight gain of about the same. Today, researchers view this rule as overly simplistic. They now think of human energy balance as "a dynamic and adaptable system," as one study describes. When you alter one component — cutting the number of calories you eat in a day to lose weight, doing more exercise than usual — this sets off a cascade of changes in the body that affect how many calories you use up and, in turn, your bodyweight. One very underappreciated fact about exercise is that even when you work out, those extra calories burned only account for a tiny part of your total energy expenditure. There are three main components to energy expenditure, Kravitz explained: 1 basal metabolic rate, or the energy used for basic functioning when the body is at rest; 2 the energy used to break down food; and 3 the energy used in physical activity. We have very little control over our basal metabolic rate, but it's our biggest energy hog. Digesting food accounts for about 10 percent. That leaves only 10 to 30 percent for physical activity, of which exercise is only a subset. You can read more about this concept here and here. Using the National Institutes of Health Body Weight Planner — which gives a more realistic estimation for weight loss than the old 3,calorie rule —the NIH's Kevin Hall created this model to show why adding a regular exercise program is unlikely to lead to significant weight loss. If a hypothetical pound man added 60 minutes of medium-intensity running four days per week while keeping his calorie intake the same, and he did this for 30 days, he'd lose five pounds. More on these "compensatory mechanisms" later. So if one is overweight or obese, and presumably trying to lose dozens of pounds, it would take an incredible amount of time, will, and effort to make a real impact through exercise. That's why Hall thinks researchers find again and again that exercise can help maintain weight loss, but it doesn't help people lose weight. Exercise can even undermine weight loss in subtle ways. How much we move is connected to how much we eat. As Hall put it, "I don't think anybody believes calories in and calories out are independent of each other. One study shows that people seemed to increase their food intake after exercise — either because they thought they burned off a lot of calories or because they were hungrier. Another review of studies from found people generally overestimated how much energy exercise burned and ate more when they worked out. A single slice of pizza, for example, could undo the calories burned in an hour's workout. So could a cafe mocha or an ice cream cone. There's also evidence to suggest that some people simply slow down after a workout, using less energy on their non-gym activities. They might decide to lie down for a rest, fidget less because they're tired, or take the elevator instead of the stairs. These changes are usually called "compensatory behaviors," and they simply refer to adjustments we may unconsciously make after working out to offset the calories burned. The most intriguing theories about why exercise isn't great for weight loss describe changes in how our bodies regulate energy after exercise. Researchers have discovered a phenomenon called "metabolic compensation. In other words, our bodies may actively fight our efforts to lose weight. For one fascinating study, published in the journal Obesity Research in , researchers subjected seven pairs of young, sedentary identical twins to a day period of intense exercise. For two hours a day, nearly every day, they'd hit a stationary bike. The twins were also housed as inpatients in a research lab under hour supervision and fed by watchful nutritionists who measured their every calorie to make sure their energy intake remained constant. Despite going from being mostly sedentary to spending a couple of hours exercising almost every day, the participants only lost about 11 pounds on average, ranging from as little as 2 pounds to just over 17 pounds, almost all due to fat loss. The participants also burned 22 percent fewer calories through exercise than the researchers calculated prior to the study starting. By way of explanation, the researchers wrote that either subjects' basal metabolic rates slowed down or subjects were expending less energy outside of their two-hour daily exercise block. In a more recent study, published in Obesity in May , Kevin Hall's group again looked at 14 of the Biggest Loser reality show participants. They took a number of measurements — bodyweight, fat, metabolism, hormones — at the end of the week competition in , and again six years later, in Though all the contestants lost dozens of pounds through extreme diets and hours of exercise at the end of the show, by the six-year mark their waistlines had largely rebounded. But the most remarkable finding was that the participants' metabolisms had vastly slowed down through the study period. They were essentially burning about fewer calories about a meal's worth each day than would be expected given their weight. This metabolic effect persisted, despite the fact that most participants were slowly regaining the weight they lost. Dugas calls this phenomenon "part of a survival mechanism": The body could be conserving energy to try to hang on to stored fat for future energy needs.

Discussion This study has identified processes that may be important influences on behaviour in weight management, particularly through decision-making during key situations. The maintenance energy gap estimates the increased energy intake needed to maintain higher average weights following the obesity epidemic. Table 1 shows data from the — Korea National Health and Nutrition Examination Surveys KNHANES. Swinburn et al. Applying this result to the KNHANES data, the energy maintenance gap of kcal since would be predicted to result in a weight gain of 4. In reality, the average weight gain of men was only 2. This is a substantial change and shows that the reversal of obesity would require substantially large changes in terms of energy balance. However, population weight has been accumulating for decades in most countries, and higher weights require greater energy intake to maintain. Thus, the difference between the energy required to stop weight gain and that required to reduce a specified amount of excess weight—the much larger maintenance energy gap—should be addressed. Thus, obesity prevention should be given priority, considering the limited effects of behavioral and pharmacological measures to lose weight. The U. Healthy People objectives include reducing obesity prevalence among adults aged 20 years and older from A simulation study suggested that an 8. However, the same researchers concluded that no single population-level intervention would achieve the Healthy People objective if implemented alone. For example, community-based moderate- to high-intensity exercise programs with dietary counseling could only reduce the energy intake by 1. Recently, the Korean Ministry of Health and Welfare announced its national comprehensive measures for obesity management and proposed to continue curbing the growth of the obesity rate to maintain the figure at the level of It must be verified if this goal is feasible with the current available interventions. Young children are the top priority for obesity prevention; they have the smallest energy gaps to change and could be the first population to show evidence in reversing the epidemic. In particular, two interventions have attracted attention for cost-savings within a year period in the United States: an excise tax on sugar-sweetened beverages and elimination of the tax subsidy for TV advertising directed at children for nutritionally poor foods and beverages. Excise and sales taxes on sugar-sweetened beverages are already in place in over 20 countries, and the effects are under investigation. Dynamic energy balance can effectively explain body weight change following negative energy balance. A change in energy intake influences energy expenditure. Whether diet-induced or exercise-driven, weight loss leads to a decrease in TEE, REE, and non-REE. Changes in body composition occur differently with elapsed time after the negative energy balance is achieved. During the first several weeks of calorie restriction, rapid weight loss occurs due to the combined effects of glycogen, protein, and fluid loss. With ongoing negative energy balance, fat mass decreases slowly due to the slower rates. Using a mathematical model can help clinicians provide individuals advice about diet control. It is important to emphasize steady efforts to maintain reduced weight over efforts to lose weight. This is a substantial change and reveals that reversal of obesity requires large changes in terms of energy balance. Because obesity is difficult to reverse, obesity prevention must be prioritized, along with implementation of obesity prevention strategies with high feasibility, broad population reach, and relatively low cost for young children, who have the smallest energy gaps to change. It is difficult to reduce the rapidly increasing obese population with only one strategy. Therefore, it is necessary to establish a complex approach to prevent obesity by paying attention to the results of practical application of several strategies shown to be successful through cost-effectiveness analysis.

Static versus dynamic energy balance Reducing energy intake for weight control causes a negative energy balance, which means that energy intake is less than energy expenditure. Dynamic energy balance compensates for long-term weight gain Individuals with normal weight maintain their energy balance over a period of time in a remarkably accurate way. Short-term adaptation after weight loss According to dynamic energy balance, weight loss results from a negative energy balance and changes in body composition Fig. Changes of body composition and energy expenditure after rapid, dramatic weight loss It is possible to obtain important information about changes in body composition and energy expenditure after dramatic weight loss from the results of an American competition reality show. Estimation for obesity treatment at the individual level Using a mathematical model that reflects dynamic energy balance, it is possible to make personalized calorie and physical activity plans to reach a goal weight within a specific time period and to maintain it afterward. The author declares no conflict of interest. Overview of metabolic adaptation of the typical outpatient weight loss and regain trajectory. During the first few days to weeks of caloric restriction, metabolic adaptation occurs in the resting energy expenditure REE. In this period, weight decreases rapidly in the fat-free mass FFM due to the combined effects of glycogen, protein, and fluid loss. On the other hand, fat mass FM slowly decreases during the period of subsequent caloric restriction. Behavioral and metabolic adaptation of dieters contributes to the typical outpatient weight plateau and regain trajectory. Adaptive thermogenesis is characterized by an adaptation of the REE, which is maintained throughout further weight loss and during successful maintenance of reduced body weight. Metabolic adaptation persists over several years after weight loss. Web-based simulations for setting goals for weight loss and maintenance of reduced weight. The panel located on the top-left part of the simulator window specifies the baseline characteristics of the individual person or population average values. This example illustrates weight-related information for an kg, cm-tall, and year-old woman. The top-middle panel specifies the goal weight 72 kg and desired time interval to achieve the goal days. The simulation displays the required changes of dietary energy intake to meet the goal and maintain the weight change. The simulated body weight trajectory is graphically displayed in the lower panel. Users can also modify physical activity to examine how the combination of diet and exercise interventions can achieve the same goal.

I started my journey in June and have lost 32 pounds in 4 months. I would recommend this to everyone who needs to lose. Lots of positive affirmations. By learning those life lessons, our eating challenges naturally begin to heal and dissolve.
A simple way to say this is that transforming your relationship with food is an extraordinary and skillful blend of science, psychology , nutrition , and emotion.
My work not only consists of dynamic eating psychology, but also mind-body nutrition. Mind-body nutrition is another exciting and timely new field that advances the practice of clinical nutrition by exploring the psychophysiology of how thoughts, feelings, and beliefs impact nutritional metabolism and health.
Originated by Marc David, Founder of the internationally acclaimed Institute for the Psychology of Eating where I studied , it goes far beyond standard nutrition by focusing on the connections between brain , body , and behavior.
When it comes to good nutrition, what we eat is only half of the story — the other half involves who we are as eaters. Mind-body nutrition reveals how stress physiology, the relaxation response, breathing, awareness, pleasure, meal timing, and much more profoundly influence digestion and calorie burning.
Did you know that your mind and emotions can have a powerful influence on digestion? Are you aware that low energy can be driven by fear of food and negative thinking about the body?
Or that high energy can be created by changing the timing of your meals? Do you know how to use pleasure to fuel metabolism? Have you discovered that appetite can decrease during stress? Mind-body nutrition offers practical and results-oriented strategies for the most commonly seen eating challenges and health issues of our times.
Dynamic eating psychology and mind-body nutrition allow me to effectively wear the hats of a nutritionist, life coach, and counselor with my clients. My goal is to support you with coaching strategies and informed nutrition principles that are nourishing, sustainable, and yield results.

Obesity affects all ages:. Weight gain can obviously be associated with consuming too many calories or eating a diet of processed and sugary foods in addition to not getting enough exercise.
A lot of the factors that affect your weight are interdependent on each other. Just as sleep can cause issues with cortisol levels and the way you handle stress, the reverse is also true.
The thyroid gland regulates metabolism which can affect just about every other hormone function in your body. All of your hormones work as a complete symphony together. Fortunately, the reverse is also true.
Once the root cause issues are identified, they can be addressed both individually, and as a whole, and the results can be exponentially positive, both in the way you feel and the way that you look!
According to the International Journal of Obesity, researchers have found that obesity and higher BMIs were associated with less than six hours of sleep a night.
Identifying and addressing sleep issues to ensure consistent and adequate amounts of sleep can not only make you feel more rested and energetic, but can also lead to a lower BMI and a reduction in weight. This is because a rested mind and body impedes cortisol secretion, allowing your body to appropriately expend energy and not hold on to excess fat.
Cortisol is needed to live, sleep, manage stress, regulate mood, balance blood sugar, regulate blood pressure, and modulate the immune system. With constant stress, your cortisol levels can rise, staying at high levels throughout the day. Too much cortisol directly causes tissues in the body to no longer respond to other hormones, creating a condition of hormonal resistance.
Imbalanced cortisol levels can cause insomnia leading to a lack of sleep and lack of sleep can elevate cortisol levels so that it becomes an endless cycle.
Cortisol imbalances can also cause carbohydrate and sugar cravings, create thyroid imbalances which regulate metabolism , and adversely affect the way that you handle stress. Because cortisol is the fight-or-flight hormone and both high-stress levels and lack of sleep can cause imbalanced levels, this condition can become chronic.
When your body is constantly reacting to stress, it goes into survival mode, thus effectively shutting down non-essential functions, including digestion. High cortisol also signals the body to hold on to fat stores, especially the visceral fat around the abdominal area.
