Can You Lose Fat and Build Muscle at the Same Time

This has to be the most asked question a trainer gets. If you've lifted consistently for a few years, trying to lose fat and build muscle at the same time usually means doing both of them slowly. People want both at the same time, but that's not necessarily feasible for everybody. Losing fat needs you eating a bit less than you burn. Building muscle goes best when there's enough food to recover from your training and your lifts keep going up. Early on your body can do both off the same plan, and the longer you've trained, the harder it gets to have both. At some point the answer turns into picking one and running it first.

Who it works for

If you're new to lifting, your body responds to almost any decent training, so you can usually build muscle and lose fat while eating a little less. Muscle you've had before comes back faster than it took to build, so coming back after a long break works the same way. Carrying more body fat helps too, because there's more stored energy to draw on.

When you've trained for years

Once you've trained steadily for a few years, the easy muscle is already on you. What's left comes slowly, and it comes slowest when you're eating less, because there's less food coming in to build with. So you cut your food to lose fat, keep training hard, and a few weeks in your lifts stall. The scale moves a little, the mirror barely changes, and it feels like the plan isn't actually doing anything. So you eat more to get the lifts moving again, and the fat loss stops. You can go back and forth like that for a long time and end up close to where you started. Neither half of it was wrong. Fat loss and building muscle each need a different amount of food, and one plan can't give you both amounts at once.

Picking one

Start by working out which group you're in. If you're newer to lifting, coming back after time off, or have a fair bit of fat to lose, go for both. Eat a little under what you burn, get some protein in every meal, and keep adding weight or reps to your main lifts. Write the lifts down every session. If they're still going up after 6 weeks of eating less, it's working and you can keep going.

If you've trained for years and your lifts have barely moved in a while, pick one. If losing fat is what you want most, run that first for 8 to 12 weeks. Eat a bit less and keep the weight on your main lifts where it was. On a Dumbbell Split Squat, that means holding the dumbbells you were already using rather than dropping to lighter ones because you're eating less. Holding your strength through a cut is what keeps the muscle you've already built. After that, bring your food back up to around what you burn, or a little over, and spend the next few months building with your lifts going up again. If you're already fairly lean and the goal is more muscle, flip the order and build first.
