Insulin regulates free fatty acid (FFA) appearance in plasma primarily by inhibiting lipolysis, while maintaining a constant absolute rate of primary intra-adipocyte FFA reesterification.

Insulin controls blood fat levels mostly by stopping fat cells from releasing fat, not by burning it. This happens at relatively low insulin levels. High insulin levels are needed to significantly change how much fat your muscles burn. For weight management, keeping insulin levels stable helps prevent fat release from adipose tissue.

In conclusion, insulin regulates FFA Ra by inhibition of lipolysis while maintaining a constant rate of primary FFA reesterification.
