Is it that simple? Can the clothing you choose increase your energy expenditure? Is hotter better?
A visit to the Zaggora Hot Pants website reveals that their research studies were conducted on 13-14 participants, a far cry from the robust sample sizes needed to draw meaningful conclusions. This exercise physiologist's website does a good job at challenging Zaggora's claims about their products.
As with many weight loss programs, plans, products, gimmicks, etc., if it sounds too good to be true, it probably is. When you learn about the new it-product, remember to think objectively, critically, and scientifically.
So, skip the Hot Pants and save your hard-earned cash for gym wear that provides fit, function, and style.
