Most men get this wrong. They either avoid cardio completely or overdo it and start losing size along with fat.
The reality is simple. Fat loss comes from a calorie deficit, but how you create that deficit determines whether you keep muscle.
Research shows that 150 to 300 minutes of moderate intensity cardio per week is enough for meaningful fat loss.
That breaks down to about 20 to 40 minutes, 4 to 5 days per week. You do not need hours of daily cardio.
The key is intensity. Stay in Zone 2, roughly 60 to 70 percent of max heart rate, for the majority of your work. This is where your body relies more on fat for fuel and where recovery cost stays low. Moderate intensity is defined as effort where you can still hold a conversation.
You can layer in 1 to 2 short high intensity sessions per week, around 10 to 15 minutes total work. This helps maintain conditioning and metabolic output without interfering with lifting performance.
Lifting still drives the outcome. Guidelines consistently show that combining cardio with resistance training leads to better overall body composition and health outcomes than cardio alone. Aim to lift at least 2 to 3 days per week alongside cardio.
One more number that matters. Once cardio volume pushes past 300 plus minutes per week, you start entering a range where benefits plateau and recovery demands increase.
The takeaway is controlled volume, not extremes.
4 to 5 cardio sessions, mostly Zone 2, paired with consistent lifting is enough to lean out while staying strong.
