Virtual Enhanced Lifestyle for Metabolic Syndrome (ELM) Proof-of-Concept Study

Inclusion Criteria: 1. Men and women with components of the metabolic syndrome, defined by an adapted version of the Joint Interim Statement of the IDF, NHLBI, AHA, WHF, IAS, IASO (Alberti, 2009). Surrogates for waist circumference and fasting glucose were selected to help identify prospective participants using medical records. Participants must have ≥ 2 of the following five criteria to participate in the study: * Waist circumference based on AHA/NHLBI (ATP III) cut points of ≥ 102 cm for men and ≥ 88 cm for women or BMI≥30 * Triglycerides ≥150 mg/dL or treatment for elevated triglycerides * HDL cholesterol \<40 mg/dL in men or \<50 mg/dL in women, or treatment for low HDL * Systolic blood pressure ≥130 m Hg, diastolic blood pressure ≥85 mm Hg, or treatment for hypertension * Fasting plasma glucose 100-125 mg/dL (range inclusive), or on metformin, or HbA1c between 5.7 and 6.4. 2. Age 18 years or older 3. Highly motivated to make lifestyle changes as a way to manage the MetS. Exclusion Criteria: 1. Individuals who report being unable to walk 2 consecutive blocks without assistance are ineligible. Additionally, individuals who endorse pain, tightness, or pressure in their chest during physical activity (on question 1 of the EASY screener) or current dizziness or lightheadedness (on question 2 of the EASY screener) may not be randomized without providing documentation in writing from their physician indicating that they have been cleared for participation in the trial. 2. Unwilling, unable, or not ready to make the lifestyle changes prescribed in ELM 3. BMI \<27 or \> 40 4. Weight \> 397 lbs.

Unable or unwilling to give an informed consent or communicate with study staff. 7. Unable or unwilling to complete accelerometer data collection. 8. Does not have reliable access to the internet. 9. Does not have a smart phone. Must be willing to download the Fitbit app on their smart phone. 10. Not fluent in English 11. Current diagnosis of type 1 or type 2 diabetes, on any diabetes medications except metformin, or has a screening A1c ≥6.5 12. Inpatient treatment for a psychiatric condition within the past 6 months, or currently receiving treatment for schizophrenia or other serious psychiatric illness 13. Probable major depression, defined as a PHQ-8 score ≥10 14. Pregnant women, planning a pregnancy in the next 2 months, given birth in the last 6 months, or currently breastfeeding 15. ≥ 30 total days of oral corticosteroid use within the last year, history of solid organ transplant, or history of stem cell transplant 16. Problematic use of alcohol and/or recreational drugs, defined as ASSIST screening score of ≥27. 17. Self-reported or known history of an eating disorder (e.g., binging and purging) in the past 5 years 18. Use of weight loss medications (Qsymia, orlistat, phentermine, Saxenda, etc.) in the last 3 months, or unwilling to abstain from taking weight loss medications or supplements during the trial 19. History of bowel resection surgery or bariatric surgery 20. Any medical condition known to influence the etiology of MetS as judged by the study physician (e.g., uncontrolled hypothyroidism, endocrine hypertension, etc) 21. History of major cardiovascular illness, including: a) stroke; b) myocardial infarction; c) congestive heart failure requiring hospitalization, or greater than NYHA heart failure class I; d) uncontrolled hypertension (SBP\>180 or DBP \> 109); e) unstable angina or an active prescription for sublingual nitroglycerin; or f) other major cardiovascular illness which the site PI determines could limit ability to participate in the trial. Individuals screened for participation, whose screening systolic blood pressure is ≥160 and ≤179, or whose screening diastolic blood pressure is ≥100 and ≤109 are considered to have MODERATE, or Stage 3 Hypertension. If they otherwise qualify and wish to participate in ELM, they will be referred to their physician for clearance prior to randomization. 22. Cognitive impairment 23. Visual or hearing impairment 24. Currently taking or expecting to take any of the following exclusionary medications: 1. Antiretroviral therapy (e.g., HAART) 2. Weight loss medications (as in #14) 3.
