Dear All

In a recent edition of Mens Health I seen an advertisement for
ineffect a plastic t-shirt. It reminded me of an old 70's boiler/
spacesuit. Basically it makes you sweat. Though I know and the maker
does also state that on consumption of water it does not make you lose
weight, however they claim that the act of sweating actually causes
the burning of calories.

I would be interested to read your opinions.

thanks G

I'm no expert, but bundling up to the point of sweating seems like it
would burn LESS calories over time. Because you're being insulated,
I'd imagine your metabolism would adjust accordingly over time.

When I used to wrestle, techniques like this were used by people
needing to make weight the day of a match, if they were a pound or two
over their class. However, it's just water and of course comes right
back.

Maybe there's some research to the contrary, but even if this did
somehow burn calories, I can't see it being more effective than
drinking cold water.

To me this seems like a crazy idea. User risks dehydration and heat
stroke for no benefit. I read an article about those things recently,
apparently they are popular in some South American countries, in
aerobics class.

If sweating alone burned calories, then maybe my country wouldn't have
an embarassing third place in the fattest nation in EU comparison,
since we like to sweat in saunas.

On their website it does state that you should continually consume
water, I assume to prevent dehydration. It also recognises that any
weight loss is replaced as soon as you drink water.

It is the actual act of prespiring that they claim burns calories.

I know whenever I am ill with a temperature and therefore, prespiring
that I have lost weight but I have always put that down to loss of
appetite. It could be a mixture of loss of appetite and the act of
sweating

Lose enough water and it quickly becomes unhealthy.
Then the body immediately tries to regain the water on a
time scale of hours.

Lose enough fat and it can take a very long time to
become starved unhealthy. Then the body tries to regain
the fat on a time scale of months.

In spite of the fact that both water and fat register on the
scale, water is not fat. If your goal is to lose fat then
efforts spent losing water are wasted efforts.

Sweat is a cooling mechanism. When water evaporates
it takes heat energy and that heat is drawn from whatever
the water was touching. Prevent the evaporation with a
plastic suit and you've prevented the cooling effect. No
cooling effect, no need for the body to compensate with
a higher metabolism.

This suggests it will work better to stand in front of a fan
and have the wind dry you out. Feel cold from the chill,
and your body needs to burn more calories to compensate.
If that worked well lot's of people would do it ...

Higher temp does mean higher metabolism. Not sure how
much loss is from which.
