Can TRT help with weight loss?
Last updated: January 2026
Quick Answer
TRT can support fat loss by improving body composition — increasing lean muscle mass while reducing visceral (belly) fat. Studies show men on TRT lose an average of 3-6 kg of fat mass over 12 months. However, TRT works best combined with resistance training and a protein-rich diet for optimal body recomposition.

Setting realistic expectations for TRT helps you stay the course during the optimization process. Most men begin feeling improvements within the first few weeks, with full benefits developing over 3-12 months.
