By ignoring the root causes of disease and neglecting to prioritize lifestyle measures for prevention, the medical community is placing people at harm. Advanced nations, influenced by a Western lifestyle, are in the midst of a health crisis, resulting largely from poor lifestyle choices. Epidemiologic, ecologic, and interventional studies have repeatedly indicated that most chronic illnesses, including cardiovascular disease, cancer, and type 2 diabetes, are the result of lifestyles fueled by poor nutrition and physical inactivity.In this article, we describe the practice of lifestyle medicine and its powerful effect on these modern instigators of premature disability and death. We address the economic benefits of prevention-based lifestyle medicine and its effect on our health care system: A system on the verge of bankruptcy. We recommend vital changes to a disastrous course. Many deaths and many causes of pain, suffering, and disability could be circumvented if the medical community could effectively implement and share the power of healthy lifestyle choices. We believe that lifestyle medicine should become the primary approach to the management of chronic conditions and, more importantly, their prevention. For future generations, for our own health, and for the Hippocratic Oath we swore to uphold ("First do no harm"), the medical community must take action. It is our hope that the information presented will inspire our colleagues to pursue lifestyle medicine research and incorporate such practices into their daily care of patients. The time to make this change is now.

Purpose of reviewPlant-based diets have been used with growing popularity for the treatment of a wide range of lifestylerelated diseases, including diabetes, hypertension, and obesity. With the reinvigoration of the dietary management of chronic kidney disease (CKD) and the use of low protein diets for secondary prevention of CKD to delay or prevent dialysis therapy, there is an increasing interest in the potential role of plant-based diets for these patients. Recent findingsRecently, a body of evidence related to the role of plant-based diets in preventing CKD has reemerged. Several observational studies have shown that red and processed meat have been associated with increased risk of CKD as well as faster progression in those with preexisting CKD. In several substitution analyses, replacement of one serving of red and/or processed meat has been linked with sizable reductions in CKD risk. Although limited, experimental trials for the treatment of metabolic acidosis in CKD with fruits and vegetables show outcomes comparable to oral bicarbonate. The use of plant-based diets in CKD may have other benefits in the areas of hypertension, weight, hyperphosphatemia, reductions in hyperfiltration, and, possibly, mortality. The risk of potassium overload from plant-based diets appears overstated, mostly opinion-based, and not supported by the evidence. Plant-based diets are generally well tolerated and provide adequate protein intake, including essential amino acids as long as the diet is correctly implemented.

Lifestyle-related diseases have common risk factors: physical inactivity, poor diet, inadequate sleep, high stress, substance use, and social isolation. Evidence is mounting for the benefits of incorporating effective methods that promote healthy lifestyle habits into routine health care treatments. Research has established that healthy habits foster psychological and physiological health and that emotional well-being is central to achieving total well-being. The Happiness Science and Positive Health Committee of the American College of Lifestyle Medicine aims to raise awareness about strategies for prioritizing emotional well-being. The Committee advocates for collaborative translational research to adapt the positive psychology and behavioral medicine evidence base into methodologies that address emotional well-being in nonmental health care settings. Another aim is to promote health system changes that integrate evidence-based positive-psychology interventions into health maintenance and treatment plans. Also, the Committee seeks to ameliorate health provider burnout through the application of positive psychology methods for providers' personal health. The American College of Lifestyle Medicine and Dell Medical School held an inaugural Summit on Happiness Science in Health Care in May 2018. The Summit participants recommended research, policy, and practice innovations to promote total well-being via lifestyle changes that bolster emotional well-being. These recommendations urge stakeholder collaboration to facilitate translational research for health care settings and to standardize terms, measures, and clinical approaches for implementing positive psychology interventions. Sample aims of joint collaboration include developing evidence-based, practical, low-cost behavioral and emotional assessment and monitoring tools; grants to encourage dissemination of pilot initiatives; medical record dashboards with emotional well-being and related aspects of mental health as vital signs; clinical best practices for health care teams; and automated behavioral programs to extend clinician time. However, a few simple steps for prioritizing emotional well-being can be implemented by stakeholders in the near-term.

Background Lack of adherence is a primary reason people fail to maintain a healthy diet or lose weight. Multiple environmental factors, including aggressive marketing and convenience of nutrient‐poor food, undermine people's best intentions. The aim was to assess the feasibility, acceptability and impact of food prescriptions in which participants' exposure to commercial food outlets is reduced, because the groceries are delivered with weekly menu plans and recipes. Methods This is a series of pre‐post pilot proof‐of‐concept studies. We recruited 37 members of Kaiser Permanente interested in improving their diet or losing weight. Weekly meal plans meeting more than 90% of recommended dietary allowances were designed to be low cost, in line with Supplemental Nutrition Assistance Program (SNAP) allowances. Five separate pilots targeted different populations. Participants were required to provide 24‐h dietary recalls (ASA24) before and during the interventions. Weight management pilot participants had height, weight and blood pressure measured before and after 4‐week pilots and followed sustainability guidelines, limiting meat and dairy. Results Across pilots, the healthy eating index improved (+21.1 points; 95% CI [confidence interval] 15.9, 26.3). For the weight management pilots, most participants lost weight (average 10.3 lbs for men, 5.7 lbs for women; 95% CI −10.2, −5.4). The majority of participants liked the programme and considered it the easiest weight loss programme they ever tried. Conclusions These pilots suggest that meal planning and grocery delivery can be affordable and acceptable and could ultimately have a major impact on diet‐related chronic diseases. Longer‐term studies are needed to confirm how long compliance will endure.
