Do you weigh more after a work out | Forum
I have a client trying Jenny Craig.
I don’t endorse it either way but she wanted to try it for various reasons I won’t go into here.
I am supporting her for now.
But, that has nothing to do with my question.
She left my work out and went straight there for her weigh-in.
She was very dissapointed to find out she’d only lost a half a pound in the second week (one pound the first week).
The “counselor” got very defensive when my client showed how upset she was and told her it was “that work out at the gym” causing a weight gain.
She told her that one always weighs more after a work out because the muscles bulk up, retaining water, and that is why her weight was up.
Anyone ever hear of this? Mind you, my client cannot work out very hard because of some physical problems so we hardly do a hard weight training session.
Then, she does a half an hour of cardio which I always thought causes weight loss from loss of water due to sweating.
I never heard of a
temporary weight gain due to the muscles being worked out.
What do you all think? I want to check things out and make sure I am up on the latest information.
I do not like the idea of food that does not need to be refrigerated to start with or a 1 size fits all nutrition plan.
Strength training does not add to body weight unless she drinks in more fluids than she sweats out.
The law of physics is a law, so there is no way what she was told at weigh in could be true that close after her workout.
Now if her meals are full of salt which shold be on the package.
Then it is possible.
But that would be about 4 cups of fluid in excess of what she sweated.
If she was doing well before her change she should have stayed with that.
Stay with a proven, scientific outline and try to keep her focust on facts if she will listen.
The only thing I could think of is that her sodium intake is high causing her to retain water.
The other thought is that strength training does increase your appetite.
It could be that.
Although her meals are premade and portioned you know the old adage…what you eat in private shows in public.
The only non-medically related items that I believe could have a possible
effect of a weight gain after a workout would be glucose repletion with
water uptake, sodium as has already been addressed by another and possibly
The glucose repletion can cause some retention of
water as for every gram of glucose taken into the muscle cell will have
associated amount of water taken in with it; however, for this to a have a
plausible or noticeable weight gain it would happen over a 24-72hr time
Again, sodium has been associated with water retention, but this
would be something that would happen over a longer time period then just a
couple of hours post exercise.
There would be a similar idea with creatine
Some medical conditions can also lead to water retention as well, say like
issues with the kidneys.
Some medications can also cause fluid retention as
I don’t know the medical history, so can’t get a better idea of the
In my experience, there can be weight fluctuations either way even on a day
to day basis.
Lot depends on the quantity and type of food eaten over the
previous 24-48 hours…
There is no way that a person can weigh more immediately after weight
training because of weight training!
It could be that by the second week, she also put on healthy LBM along with
losing fat, and so the net loss was shown only 1/2 a lbs., though she might
have lost 1 or more lbs of fat, and how this gain in LBM is important for
Maybe she could focus more on her inches and how she looks and
feels, rather than body weight…
I think this lady could be dealing with something in her life and this
incident of losing only 1/2 lbs was a trigger that caused an emotional
outburst of some sorts…
It often happens.
When a person trains they loose water via sweat, even though they may not seem to sweat a lot.
It is the bodies cooling mechanism.
Now if the person drinks more water during their workout, they will weigh more.
I see this all the time with women who start a strength training
program and have never done any resistance work before.
stages of the program increases endurance, stamina and blood volume.
Next comes strength and lastly comes increased muscle mass.
problem with most women is they are focused on how much they weigh,
rather than how many inches they have lost – I can attest to this from
my own personal experience BEFORE I became educated in fitness and
certified as a trainer.
The media and the health industry conditions us to think we need to
weigh a magic number, and while I agree that most clients need to lose
weight – the first change we see is loss of body fat while we increase
Men don’t seem to have this problem – probably because they
start out with a much higher percentage of lean mass in the first
Women have to go through this “flip the scales” process.
Tell her to start monitoring her waist and hip measurements and to
stop focusing on the scale alone.
If she is doing this right, her
inches will come down first.
I have seen this with too many clients
and I stand adamantly behind this.
You can’t use the scale in a
Also, keep in mind you can be your desired weight and still be
obese based on the percent of fat mass you have in relation to your
So, your goal can’t just be to weigh your magic number.
She also needs to give this more time.
Two weeks is NOT a bench mark.
It takes two weeks for your body to adapt to any metabolic changes
caused by a change in your nutrition.
Once that happens THEN you will
see your body respond.
That is why you don’t take body fat
measurements any closer than 4 weeks apart.
You need two weeks to
adapt and two weeks for the changes to take hold.
Just for added support – I weigh 10 pounds more than my average weight
was in the past, but my waist, hip and bust measurements are
So, I lost fat mass, gained lean mass and I am the same
size in inches as I was when I weighed 10 pounds less.
I don’t care
what the scale says! I don’t need to “lose” those last 10 pounds – I
already lost the inches.
Many good points were brought up her.
In general, if someone’s body is
not used to working out it does not store much glycogen-no need to.
activities are added the body adapts by increasing glycogen stores-for
every 1 molecule of glycogen there are 3 water molecules attached-yes
your weight may be up.
What concerns me is there is no mention of body
fat or other measurements identified here.
I would focus on those
numbers not just the “weight”.
Yes, you are correct.
Body composition and health are two major factors that
should be considered.
This could possibly provide and opportunity to sit
down with the Jenny Craig counselor for education and networking.
Thanks for all who responded to my question.
The focus was not on why she hasn’t lost weight but more on the so-called therapist or case -worker at Jenny Craig for my client.
It just sounds like she got defensive and blamed the work out on the low weight loss.
My client couldn’t possibly be bulking up with muscle gain as we just can’t work out that hard.
Anyway, lots of information on her I didn’t include or I would have written a few paragraphs.
I just felt badly that this Jenny Craig employee was giving my client wrong information and probably does so on other subjects as well and to other people.
