so I recently had a question should I work out when I’m fasting so let’s talk

about that so many people have this idea they have to eat before the exercise to

get energy for whatever reason so let’s first talk about the three or four

variables to exercise you have the type of exercise you have the intensity of

the exercise how hard it you go and then the duration how long you go and then

you have the recovery so the purpose of exercise is to make you more fit to

increase the health of the system to build more capacity more fitness to

actually have less stress there’s many benefits of exercise but those are some

of them so what you’re doing is you’re stressing your body and then your body

is going to adapt to that and prove various things you have to be careful

not to over train because overtraining will inhibit your sleep keep your

inflammation up and reduce your gains so it’s always kind of a an adjustment of

figuring out what your optimum amount of intensity duration and recovery is

if you overtraining let’s say you only give yourself a few hours to recover you

know you’re not going to actually see any change now in the recovery mode this

is when all the good things happen glycogen reserve replenishment new

capillaries are grown new mitochondria cell structures are repaired enzymes are

restored enzymes of the things that actually do all the work in the body

lactic acid is cleared if you have too much lactic acid in your body that your

body can’t burn up because it can use this as fuel it can create a condition

called lactic acidosis which can cause Russ’s leg syndrome

difficulty breathing in a whole series of other symptoms I have videos on that

also you have the endocrine system involved where you have a really good

spike of growth hormone which is involved in improving not just muscle

growth but the growth of other proteins and also repair in general of proteins

and another hormone that has increased is called glucagon which is basically a

hormone that helps you burn more fat now the problem is when you consume food

before you workout or you do carbo-loading which I’m very much

against you decrease the amount of growth hormone that you can produce you

potentially can increase too much lactic acid in the body because glucose turns

into lactic acid and you actually greatly diminish the ability to burn fat

because when you’re actually eating the body is going to be burning up those

dietary calories and not your own calories

now when you fast you get this massive additional increase of growth hormone

now think about it exercise triggers growth hormone and fasting increases

growth hormone so when you combine them you get a huge effect of growth hormone

and what’s really cool about fasting is you get amazing reparative action so you

have this huge spike in repair in general so it’s gonna actually be come

in handy when when your your body’s trying to repair from the stress so the

body can actually get new capillaries mitochondria repair the cell structures

more efficiently when you workout during the fasting mode you can enhance fat

burning by 20 to 30% more and also you improve insulin resistance now a reason

why certain people consume carbs before workout is they’re trying to enhance the

spike of insulin to build more muscle mass but here’s the problem it also at

the same time creates insulin resistance because the body does not like too many

carbs so the more insulin resistance you have the less you’re gonna absorb as far

as amino acids and proteins nutrition but by doing fasting you develop a much

more sensitivity for insulin in general and the insulin works a lot better so

you can actually pull in a more amino acids and more nutrients I had one guy

who was working out he wanted to gain more muscle mass and he was consuming a

certain amount of calories a lot of carbs he went on keto in a minute

fasting he lost weight he wanted then gained more weight but this time when he

did it healthily and he brought his carbs up to about 50 to 60 grams per day

so he kind of maxed them out and still being on keto he

started to develop more muscle growth because of this one fact that he

improved instant resistance when before he was doing the certain amount of

calorie amount he was he wasn’t able to absorb the nutrients and protein now

with the same amount of calories different foods not having instant

resistance he was able to start absorbing these nutrients and that’s

what created more muscle mass now as far as the type of exercise this really

depends on your recovery so if your recovery is poor you do aerobic exercise

low intensity walking something real light and then you build up to more

anabolic which is more like high-intensity interval training would

be very good compound resistance exercise using as many muscles as

possible when you’re working out high intensity that would be very beneficial

to maximize your growth hormone so in summary absolutely yes you want to

strive to exercise when you’re fasting because there are so many benefits

mainly for the reparative actions thanks for watching if you’re liking this
