One drug helps move fat out of storage, and another helps burn it—so together they work better than either alone.

This study only tested one drug that reduces belly fat by boosting a growth hormone signal, but it didn’t test any drug that affects how cells burn fuel, so we can’t say if combining both would work better than just one.

This study found that a molecule from mitochondria helps burn fat and improve metabolism by turning on AMPK, but it didn’t test combining this with any other treatment that moves fat from fat tissue, so we can’t say if doing both together is better.
