Hi /fit/, got a question.

Can I lose fat and gain muscle at the same time?

Like, say I lift weights one day, then run the next day. Would this work?

are you any of these things:
a) a beginer
b) fat (not having abs != fat)
c) on steroids
d) a genetic freak
e) any of the above

if you are atleast 1 of these things the answer is yes

not really, the muscles build up mainly in your sleep that night and on the day after you've done your weightlifting and for that you need some fucking proteins and a good caloric intake even on the day after

but you can keep the inevitable fat gain to a minimum by doing some cardio in the morning, i guess

THATS NOT AT THE SAME TIME NOW IS IT

OP here, not a troll, just new to this.
Allright, can I run on one day, then endurance lift (Lower weight, higher reps) the next day, and lose fat?

OP, it is possible, but you need to be extremely precise in the timing of your meals and the intensity of your fat loss exercise... more precise than you're likely able to achieve.

For optimal fat loss, you don't want your aerobic exercise to be too intense. Around 50% VO2Max, your body's most efficient energy source is its own fat. Just a little higher than that, it starts using protein, which will inhibit or negate the muscle gain you're working on. As you approach 100%VO2Max, your cells switch to glycogen, which comes from the carbohydrates in your diet.

This is why carbs are considered 'bad' by people who don't do much high-intensity aerobic exercise-- their bodies rarely get to a place where carbohydrate metabolism is particularly efficient.

Unless you go to a sports physiologist for some very intense and expensive tests, you're never going to know what your VO2Max actually is. But jogging-wise, if your breathing is too heavy for you to talk, then you've likely gone past ideal fat metabolism point and you're burning up carbs and protein.

This is a slooow process, by the way. At low intensity, you may be burning a higher percentage of calories from fat, but you're also burning a LOWER total amount of calories. This means your jogs have to be slower and longer.
