Cómo PERDER GRASA sin PERDER MÚSCULO

When we talk about losing fat, most people think about eating less and moving more. But there are two variables that determine almost everything: how much of a calorie deficit you create and how much protein you consume. The problem is that an overly aggressive deficit not only makes you lose weight faster—it also activates mechanisms that break down muscle before fat, creating a metabolic pattern that specialists associate with worse long-term body composition markers. And no diet app warns you about that. At the same time, strength training isn't just a complement to diet: it's the signal that tells the body that muscle is worth preserving. Without that signal, it loses it by default. In this clip, Dr. La Rosa explains why these two variables operate at different levels and when the slower approach is the smarter one.
