How does your body prioritize what it burns for energy when it is in a calorie deficit? I know that the "trick" seems to be to keep doing weightlifting while in a calorie deficit that isn't too large. I guess this helps get your body into a mode where it is consuming stored fat for energy rather than muscle tissue. Say I were to stop working out for about 2-3 months and eat 500-750 cals less a day to put me in a calorie deficit. I weigh 180 at about 14-18% bf. What kind of lean muscle and fat loss would I be looking at.

pic unrelated although interesting.

your does not burn muscle tissue for energy, muscle tissue is gradually broken down and in a calorie deficit your body cant naturally repair it

As far as I know you can have a 70 kcal deficit for every kilogram of fat on your body, I.E if you have 10 kilos of fat you can have a 700 kcal deficit every day and still burn 700 kcal of fat before muscles, but there's so much shit though like: "run in the morning when your glycogen levels are low and your body has to burn fat" but then i'm all: "Why doesn't it burn muscle" so idk, same question really. Bump.

It burns the carbohydrates first, then it'll rip apart dietary fats and proteins for energy.

You're muscles will atropy and you will probably hover in the same area area of body fat %.

you fucking idiot thats not true at all, your body will burn muscle tissue to provide energy for life dependent systems. id say you burn muscle and fat at about a 50/50 rate. When not exercising.

So if you wanna lose only fat and no muscle, you have to work out aswell, what kind of workouts are we talking here? Will cardio/HIIT do or are you gonna have to do resistance training aswell? Won't resistance training break down muscle tissue? Usually that's what it does right, and then rebuilds it using a calory surplus, but since you're on a diet, there's no calory surplus to rebuild the muscle tissue so won't this just tear down your muscles even faster?

op here, I don't mean like lying in a bed for 2-3 months starving myself. Just doing regular activities and a little hockey. No starting strength weightlifting though. Also the hockey is beer league so take that exercise with a grain of salt.

id say when your body gets to the point where it runs out of carbohydrates and starts burning proteins and fats doing the resistance training will tell your body "Hey don't break down the muscle for energy we need to maintain that because it is being used" and go after the fats instead. This is only my really uneducated understanding though.

there's a biochemical switch in the liver that flips when you go to sleep and back when you wake up. It switches your metabolism from carb burning (glucosis) to fat burning (keytosis). Keytosis is how the atkins diet works. By starving your body of carbs, the liver is forced to flip the switch from glucosis to keytosis and metabolize fat instead. Your sweat smells funny from the keytones left over from keytosis, namely acetone, which is why your sweat will smell sickly sweet, like antifreeze.

This matches the finding that not getting enough sleep aggravates obesity over many years -- the fat your body would've burned normally on a full night of sleep never gets burned when you go without sleep and you slowly gain weight over time. So get your beauty rest, if you want to burn fat.

Another technique mentioned here by others is not to eat anything several hours before bedtime. So if you go to sleep at 10, don't eat or drink anything but water after 6 PM. Or 8 PM. Or 5 PM. Whatever you can make stick. Your body will run on carbs until bed, and since you haven't eaten anything for a few hours the keytosis will come from your fat cells and not the fat in your bloodstream and gut.

ketosis.

and the theory about starving yourself before bed is idiotic. this drastically increases catabolism which will in turn cause your body to burn muscle as opposed to fat.
