Folic acid is not a direct “fat-burning” supplement. Weight change is primarily driven by energy balance, diet quality, physical activity, and sleep/stress management. Folate deficiency can be associated with appetite changes, mouth soreness, or fatigue in some individuals, which may indirectly influence weight—but that does not mean it “causes weight loss” in a targeted way. If deficiency exists, supplementation can improve overall wellbeing and blood production, potentially supporting activity capacity, which can help indirectly. For weight loss strategy, however, folic acid is not a primary lever.
