The hidden tradeoff behind today’s most popular weight loss drugs
Summary
Weight loss drugs and bariatric surgery may work differently, but they lead to surprisingly similar results inside the body. Both significantly reduce fat while also causing a modest loss of muscle, reshaping overall body composition. Since muscle helps protect against early death, this balance matters more than the number on the scale. The study suggests these treatments improve health—but not without trade-offs.
