ADVICE

Preserve Muscle, Not Just Pounds

  • Avoid severe calorie restriction or methods that cause substantial muscle loss.
  • Prefer approaches that preserve or increase muscle to prevent metabolic slowdown and weight regain.
INSIGHT

SIBO As A Central Metabolic Driver

  • Small intestinal bacterial overgrowth (SIBO) and endotoxemia may be a central driver of obesity, myosteatosis, and systemic inflammation.
  • Widespread antibiotic exposure likely disrupted key microbes, enabling fecal microbes to colonize the small intestine.
ADVICE

Use Targeted Microbes For SIBO

  • Consider targeted microbes that colonize the small intestine and produce bacteriocins to displace fecal overgrowth.
  • Fermented lab-grown preparations of specific strains (L. reuteri, L. gasseri, Bacillus) showed promising SIBO normalization.
