Fully Remote, Telehealth-based Ketogenic Metabolic Therapy for Long COVID

Purpose

The goal of this clinical trial is to learn if a 12-week ketogenic diet program combined with lifestyle strategies (called KMT-LS) is practical and acceptable as a fully remote intervention for adults with Long COVID who also have Myalgic Encephalomyelitis/Chronic Fatigue Syndrome. (ME/CFS) and dysautonomia (problems with heart rate, blood pressure, or other automatic body functions). The main questions it aims to answer are: Can a ketogenic diet program be successfully delivered entirely from home using online tools and virtual support? Do participants stay in the study, follow the diet, and find the program safe and satisfactory? Do participants experience improvements in fatigue, sleep, mood, daily functioning, and symptom flare-ups after exertion? Participants will: Follow a ketogenic diet for 12 weeks with weekly virtual nutrition support sessions Use at-home tools to track their ketone levels and confirm they are following the diet Complete online questionnaires about their symptoms, energy, sleep, mood, and daily functioning at the start of the study, after 12 weeks, and again 3 months later.

  • Other: Ketogenic Metabolic Therapy
    Keto-Life is a fully remote, community-based program for individuals with Long COVID, dysautonomia, and ME/CFS that combines a ketogenic diet with lifestyle strategies. Participants followed a ketogenic diet (low-carbohydrate, moderate-protein, high-fat) with a personalized intermittent eating schedule, no added sugar, and daily benfotiamine (vitamin B1) supplementation. Electrolyte support included magnesium, potassium, sodium bicarbonate, and sodium chloride. Nutrition calls were once a week via Telehealth platform, delivered by a medical nutritionist.
  • Behavioral: Lifestyle Intervention
    Lifestyle strategies included circadian entrainment, mindfulness practices, and, when appropriate, gentle exercise and hormetic therapies such as cold or heat exposure. The Lifestyle Intervention was delivered via two 60-minute virtual group sessions, delivered by health coaches.
