Modified fasting for 4 weeks did not show increased cardiac risk in 40 inpatients. Low-calorie diets are also safe, but total fasting or poor protein supplements pose risks.

Area of Science:

  • Cardiology
  • Metabolic Medicine
  • Nutritional Science

Context:

  • Weight reduction diets, including modified fasting, are increasingly popular.
  • Assessing the cardiac safety of these interventions is crucial for patient well-being.
  • Previous studies have raised concerns about potential myocardial impact.

Purpose:

  • To evaluate the cardiac safety of a 4-week modified fasting regimen in 40 inpatients.
  • To investigate potential cardiac risks associated with weight reduction cures.
  • To compare the safety of modified fasting with other dietary interventions.

Summary:

  • 40 inpatients underwent a 4-week modified fasting protocol.
  • Routine electrocardiograms (ECGs) and radiological heart size assessments showed no myocardial lesions or conduction abnormalities.

  • Slight elevations in cardiac enzymes (CK, CK-MB, alpha-HBDH) and liver enzymes (SGOT, SGPT) suggested a reduction in fat-free body mass, potentially including myocardial elements. Electrolyte (potassium, magnesium) levels required monitoring and possible supplementation.

    • Impact:

    • This study indicates that modified fasting for moderate durations, similar to low-calorie diets (approx. 1000 kcal/day deficit), does not appear to increase cardiac risk in inpatients.
    • Total fasting and diets relying on low-quality protein supplements should be approached with caution due to potential risks.
    • Findings support the judicious use of modified fasting as a weight reduction strategy when cardiac safety is a concern, provided electrolytes are monitored.
