Study Summary

This trial is looking at the effects of dietary interventions with a low-carb and high-fat diet, plus a medical food, to help reduce symptoms of long COVID.

Who is the study for?
Adults who had COVID-19 at least 2 months ago and are experiencing ongoing neurological or physical symptoms typical of long COVID, such as fatigue, loss of smell, or shortness of breath. Participants must not be hospitalized or have conditions like chronic kidney disease stage III+, heart failure, liver cirrhosis, autoimmune diseases, active infections, certain eating disorders or be on specific medications that could interfere with the study.Check my eligibility
What is being tested?
The trial is testing a low-carbohydrate diet intervention aimed at reducing blood glucose and increasing blood BHB levels to improve long COVID symptoms. This includes avoiding sugars and starches while consuming healthy fats and proteins along with a medical food supplement. The control group will receive standard therapy without dietary changes.See study design
What are the potential side effects?
Potential side effects may include digestive discomfort due to dietary changes such as constipation or diarrhea. There might also be an adjustment period with symptoms like headaches or lethargy as the body adapts to lower carbohydrate intake.

Group I: Low CarbohydrateExperimental Treatment1 Intervention
-Low-Carbohydrate Diet Intervention:Patients will receive a study kit. The kit will contain the following: Instruction sheet containing medical food instructions and food journal and a web link to the weekly online journal A 30-day supply of the medical food, KetoCitra, developed by Santa Barbara Nutrients, Inc. KetoCitra® is a ready-to-mix powder to be dissolved in water and taken twice per day with meals. KetoCitra® contains BHB, citrate, and a blend of minerals (potassium, calcium, magnesium) and is flavored with natural lemon flavor and stevia natural sweetener.
