Abstract

Nutrition therapy as part of lifestyle care is recommended for people with type 2 diabetes. However, most people with diabetes do not follow this guideline. Changing eating habits involves obtaining knowledge and building practical skills such as shopping, meal preparation, and food storage. Just as fitness coaches use their specific knowledge base in fitness to enhance the effectiveness of their coaching, credentialed chefs trained as health coaches might combine their culinary expertise with coaching in order to improve clients' food choices and lifestyles.

This report documents the case of a 55-year-old white male physician, single and living alone, who was recently diagnosed with type 2 diabetes and reported chronic stress, sedentary behavior, and unhealthy eating habits. He participated in a chef coaching program of 8 weekly one-on-one 30-minute coaching sessions via Skype delivered by a chef trained as a health coach. During the first five meetings, the patient's goals were primarily culinary; however, with his success in accomplishing these goals, the patient progressed and expanded his goals to include other lifestyle domains, specifically exercise and work-life balance. At the end of the program, the patient had improved both his nutritional and exercise habits, his confidence in further self-care improvement, and his health parameters such as HgA1c (8.8% to 6.7%; normal <6.5%).

We conclude that chef coaching has the potential to help people with diabetes improve their practical culinary skills and implement them so that they eat better and, further, has the potential to help them improve their overall self-care. We intend to further develop chef coaching and assess its potential as we learn from its implementation.

Key Words: Coaching, cooking, lifestyle, diabetes, self-care

INTRODUCTION

Nutrition therapy as part of lifestyle care is a recommended component of the overall treatment plan for people with type 2 diabetes mellitus (T2DM).1 However, most people with diabetes do not follow these guidelines.2 Barriers to adherence include lack of understanding of dietary recommendations, limited budget, food preferences (which are at odds with the recommendations), and underdeveloped cooking skills.3,4

Recent literature suggests that nutritional counseling should move from micro- and macronutrients into food-oriented education.5 Part of the proposed solution is supplementing standard knowledge counseling about healthy nutrition with skills like shopping, meal preparation and food storage.6,7 Educational programs delivered by chefs aimed at improving culinary skills have recently emerged as one way to improve adherence to nutritional guidelines. Some of these programs have been empirically evaluated,8 and one program was reported to improve nutrient pattern intake of people with T2DM.9

Health and wellness coaches are health professionals who help patients change their behavior through strategies such as patient-directed goal-setting, content education, guided self-discovery, and accountability.10 Health and wellness coaching has been applied to help people with diabetes manage their illness and has been shown to increase medication adherence and to improve lifestyle behaviors.11

Fitness coaches are credentialed exercise professionals who use coaching skills to enhance exercise training to improve fitness outcomes. They wear two hats—training and coaching—in order to help clients develop healthy lifestyles.12 Like exercise, cooking is more than just a set of skills; it is a validation of life patterns of active engagement and self-care.13 Moreover, cooking healthful food extends from self-care to the care of others, especially families.

We suggest that credentialed chefs who are also trained as health and wellness coaches might similarly don two hats in order to improve clients' food choices and lifestyles. This case study describes an innovative form of health and wellness coaching—chef coaching (CC)—and demonstrates how it was applied to help a newly diagnosed diabetes patient improve his dietary behavior and clinical outcomes.

PRESENTING CONCERNS

The patient was a 55-year-old white male physician, single and living alone. He reported chronic high stress in both his professional and personal life, eating “on the run” (primarily high-carbohydrate, high-fat food), a low level of physical activity and no drinking or smoking.

In December 2013, during routine examination after years of infrequent medical follow-up, the patient was diagnosed with T2DM. This diagnosis of diabetes frightened him, and he was eager to find education and support for changing his eating and exercise patterns. CC was suggested as a potential support. He was referred in April 2014 to the Institute of Lifestyle Medicine at the Joslin Diabetes Center, Harvard Medical School, Boston, to participate in a pilot CC program with the goal of improving his food consumption.

CLINICAL FINDINGS

The patient reported eating high-fat, high-carbohydrate foods starting in childhood, where healthy eating was “never a focus.” He reported having been a small and slender child and adolescent (5 ft 8 in and 95 lb at age 15) who ran high school track until late adolescence, when he stopped athletic training. During young adulthood, his weight fluctuated from 180 to 230 lb, depending on whether or not he was regularly running for exercise. After age 30, with no regular exercise program, his weight increased and was maintained at 270 lb, with the exception of 3 years during which he was on the South Beach Diet, when he reduced his weight to 225 lb.

He also reported a lifelong struggle with stress, beginning with a physically abusive home environment and continued high anxiety since leaving home at age 18. During the past 10 years, he has made determined efforts to manage stress more effectively, primarily through reducing his obligations and improving his assertiveness skills.

The patient's past medical history was remarkable for gastroesophageal reflux disease treated with omeprazole (40 mg, 1/day), cervical disk herniation and carpal tunnel syndrome treated with cyclobenzaprine (10 mg, 1/day) and celecoxib (400 mg, 2/day), hypertriglyceridemia treated with fish oil (1000 mg, 1/day), and posttraumatic stress disorder. His family history was positive for T1DM (maternal grandmother). His diabetic medication included metformin (1000 mg, 2/day), and insulin glargine 40 unit/day.

On examination, the patient was obese (weight: 255 lb; height: 76 in; body mass index [BMI]: 31) with normal blood pressure (130/74) and no evidence of diabetes end organ complication. His laboratory results were remarkable for elevated triglycerides, low-density lipoprotein (LDL) cholesterol, and hemoglobin A1c (HgA1c), and low high-density lipoprotein (HDL) cholesterol; liver enzymes were normal. Clinical and laboratory data before and after participating in the CC program are summarized in Table 1.

Assessment

Before beginning CC, the patient completed an online lifestyle questionnaire (LQ) developed by Wellcoaches14 (Wellesley, Massachusetts) and a food preparation behavior questionnaire (FPBQ) developed and pre-piloted by the manuscript authors. On these, the patient reported consuming mostly processed food and food from fast-food restaurants, including mostly refined grain, one or no servings of fruit and vegetables per day, and predominantly high-fat food. He did not exercise at all. As discussed below and presented in Table 2, he also rated the importance of change in various health behaviors and rated his confidence in accomplishing those changes.

COACHING INTERVENTION

Overview

The patient participated in a CC program comprised of 8 weekly one-on-one 30-minute coaching sessions via Skype (Figure 1). During the first session, the patient identified his Wellness Vision14 and goals for the course of his participation in the CC program (see below). During each subsequent meeting, the patient reviewed his progress toward the prior week's goals and identified his goals for the coming week, using the Wellcoaches Structured Coaching Checklist.14 Coaching relied on reinforcing behaviors that the patient reported as helping him work toward achieving his goals and problem-solving when goals were not achieved, with the coach facilitating a self-discovery process.12 Practical culinary skills such as meal planning, food purchasing and storage, and healthy food preparation techniques were taught when requested. Any other requested advice, including nutritional information, was referred to active learning. No “hands on” or other cooking demonstrations were involved. A detailed description of the CC program principles10 is presented in Table 3.

Coaching Course

During the first session, using appreciative inquiry techniques,12 the coach encouraged the patient to acknowledge the gap between his decision to participate in CC and both his perceived confidence in preparing healthy food (2/10) and the importance he attributed to healthy food preparation (4/10) (Table 2). He was then guided to define a compelling Wellness Vision,12 ie, to “improve intake of healthy food through increasing time spent cooking,” and concrete realistic goals to guide his work over the course of chef coaching, such as “improving my snacking habits in the office to include just healthy snacks every day” (Table 2).

During the following four meetings, the patient's goals were primarily culinary, with a 20% to 100% completion rate, eg, “buying lean meat on Saturday and cooking it using a recipe I plan to find on the internet”; “buying healthy choices such as hummus and carrots on Saturday and bringing them to my office to be used as snacks”; “choosing a healthy cheese on Saturday while shopping.” From the sixth meeting forward, the patient included goals from other lifestyle domains, specifically exercise and work-life balance.

Coach's Reflection With a Mentor Coach

Throughout the CC program, the coach (RP) met with a mentor coach (DD) weekly who was a “silent listener” to the CC session and subsequently guided the coach in a session debriefing. Debriefing focused on two key issues we confronted in developing this new model of coaching. First, the mentor coach reinforced the coach's fidelity to the CC program standards of coaching described above. Second, the mentor coach helped the coach resolve when and how to proceed when “switching hats” from the coach/facilitator role in which the patient's expertise is elicited and the chef/expert role, in which the chef provides technical instruction.

OUTCOMES

During the final CC session, the patient reported having improved his nutritional habits in terms of buying healthful food and making healthy choices available, with the result that he ate healthful food for lunch and dinner more frequently. “I drove to Whole Foods and bought carrots and celery and hummus, tomatoes, broccoli, and cheese sauce. I brought it to the office, and ate it instead of the terrible food I usually eat. I feel better—no sugar rush and crash.” (See Table 1 for additional narratives.)

In addition to having improved his nutritional habits, he increased his exercise substantially—walking 1 mile at least two times per week “I walked 4 loops (1 mile) … I walked slowly, but it was easy so I picked it up … I felt very good to do it … I plan to do this twice a week, once [on] the weekend and once during the week after work.”

His confidence that he could change his lifestyle behaviors increased (see narrative in table 1). As a result of success in goal attainment, the patient felt inspired to continue better self-care: “This process was a good jump start … I got pointed in the right direction and got momentum. Now I want to do it for myself.”

Tests conducted during the week following the last CC session showed remarkable improvement in the patient's HgA1c and triglycerides, as shown in Table 1. There was no change in weight, BMI, LDL and HDL cholesterol, or blood pressure. The patient attributed the change in HgA1c to a combination of medication and change in his eating and exercise habits. He credited the reinforcing nature of the CC for his success in changing his lifestyle behaviors: “[It was] a nice pace and support. The gentle approach helped me give myself credit for the good things I do, and not for the bad things.”

From the point of view of the mentor coach, the coaching style was key to the patient's success in making changes: “The coach, while drawing on his expertise as a chef, nevertheless consistently encouraged the patient's self-direction via goal-setting, reflection, and exploration. The patient was strongly motivated by his accountability to his coach and by anticipating his pleasure in the changes he would be able to make.”

The patient, himself a clinician, also reported that his CC experience led him to talk more empathically to his own patients and to use “change talk”12 more often with them: “I got nicer in 8 weeks. I talk more about changing behaviors and what's holding [my patients] back. My coach did a lot of that talk to me and I find myself using it now.”

DISCUSSION

This case report introduces CC as a potential strategy for helping people with diabetes apply the nutrition education they receive so that they make healthier nutritional choices. We demonstrated that it is possible to help a patient improve his eating behavior and his confidence to improve his lifestyle over 8 30-minute weekly coaching sessions conducted by Skype with a health and wellness coach who is also a professional chef. These results align with those of other studies, which show that health and wellness coaching can improve participants' lifestyle behaviors, confidence, and motivation,11,15 and they also align with additional studies that show that cooking interventions can improve participants' time spent cooking, cooking confidence, and the nutritional quality of their diets.8

Although definitive support of a relationship between teaching culinary skills and long-term cooking behavior or health outcome is lacking, cooking initiatives have been promoted recently. Many programs that promote cooking as a necessary and appropriate response to unhealthy nutrition exist on the national, state, and community levels.8 However, the feasibility of “hands on” cooking programs in a large-scale community setting has been questioned.16 We have shown that our approach—chef coaching via phone or Skype without hands-on demonstration—has the potential to be a viable response to the need for effective and feasible programming.

Although the patient's preliminary confidence about healthy food preparation was low, he chose CC as his path. As has been seen in other coaching programs,15 his success with accomplishing goals further empowered him and was translated to interest in pursuing future goals in healthy food preparation as well as in other health behaviors. This supports the idea, also shown with fitness coaching, that focus on changing one lifestyle behavior can generalize to changes in other lifestyle behaviors.12

This particular patient enjoyed a positive change in HgA1c and triglycerides levels over the course of his coaching experience. He attributed the change to effective medication and to changes in lifestyle supported by CC. The patient's weight did not change significantly, and his evaluation did not include body composition to further discern if he had any reduction in his fat mass. Until the patient demonstrates a further decrease in cardiometabolic risk factors, additional medication targeting his dyslipidemia might be considered.

One of the patient's first goals was to schedule appointments for counseling with a dietitian and an exercise physiologist. This happened after the sixth coaching session (Figure 1). Although lack of nutritional knowledge was not a barrier in this case, a preliminary nutritional education might be consider as a prerequisite for CC. Coaching as one component of the diabetes care team was proven feasible in a primary care setting.17 As we move forward to develop the CC program, we will work to integrate CC with nutritional education and to structure it within the diabetic care team.

The potential for CC to help other patients accomplish change in health outcomes requires further testing. It is our intention to further develop the various aspects of CC as we continue to learn from its implementation. Next steps will include formal assessment of CC—ie, a randomized controlled trial comparing CC to treatment as usual (education without coaching to assist implementation) and estimates of effect size. We will also explore whether we can train certified chefs who are not health professionals to serve as CC program coaches.
