The Book on Heat Review: Claims vs. the Research

Is The Book on Heat worth it?

Worth a look (6.4/10). The Book on Heat is an information product, not a supplement, so there is no label to check, just claims. Brad Pilon is a real, previously published author (Eat Stop Eat), which puts this well above the anonymous-seller ClickBank norm. The underlying science, that heat exposure like sauna use has measurable effects on cardiovascular markers and possibly metabolism, is real and published, but it is a narrower and more mixed body of research than the sweeping list of benefits on the sales page suggests, and none of it proves the book's specific protocols work as described. At $10 for the intro bundle it is a low-risk purchase; the concern is the gap between the modest research and the broad promises.

What we liked

Named, previously published author with an established (if unrelated) bestselling book
Low one-time price ($10 intro) with no recurring charge
Free US shipping on the paperback plus instant digital access
Built on a real area of published research (heat exposure and cardiovascular/inflammatory markers), not a fabricated ingredient story

What we didn't

The specific "350 research papers" are not listed or linked on the sales page
Claims span far more outcomes (digestion, hormones, chronic disease) than the cited type of research directly supports
No refund window is mentioned on the checkout page itself, only on a separate terms page
The order page's real-time cart and guarantee text load through client-side scripts that could not be fully verified independent of the terms page

What is The Book on Heat?

The Book on Heat is a paperback and digital book from Brad Pilon, the author of the bestselling intermittent fasting book Eat Stop Eat. The sales page frames it as a synthesis of over 70 years of research on how body temperature and heat exposure affect weight, energy, hormones and aging, aimed at readers who want a science-based angle on health that does not require giving up favorite foods or exercising to exhaustion.

The page lists a long set of claimed benefits tied to "temperature science": better digestion, lower inflammation, a faster metabolism, more energy, better hunger and craving control, improved exercise performance, slower aging and help with chronic disease. It also references "over 350 research papers" supporting the book, though the papers themselves are not listed or linked on the page we reached.

It is sold as an early-release intro bundle: the digital edition is delivered instantly and the paperback ships free once available, through ClickBank, which appears as the retailer on the card statement.

Format: Digital ebook plus paperback book, one-time purchase, free US shipping. Sold by: Brad Pilon / clkbooks.com (sold through ClickBank).

Do the The Book on Heat claims hold up?

"Over 350 Research Papers Supporting The Book on Heat"

The sales page mentions this figure and offers a 'read more' link but the papers themselves are not listed on the page we reached, so the specific studies behind each claim cannot be checked from the sales page alone. Published research on heat exposure (sauna bathing, hot-water immersion) does exist and shows associations with cardiovascular and inflammatory markers, but that is a narrower body of evidence than '350 papers' covering the full list of claims on the page.

Heat exposure helps with "boosting your metabolism" and "controlling hormonal responses that influence hunger and cravings"

Some small studies link heat exposure to changes in metabolic and inflammatory markers, but a direct, well-established effect on appetite hormones or sustained metabolic rate increase sufficient to drive meaningful weight loss has not been established in the research we found.

"As a treatment for many chronic diseases"

Reviews of sauna and thermal bathing research describe associations with lower cardiovascular and all-cause mortality in observational cohorts, mainly from Finland and Japan, not proof that heat exposure treats disease. Observational associations are not the same as a demonstrated treatment effect, and the sales page does not distinguish between the two.

How much does The Book on Heat really cost?

Option	Total	Per month	Shipping
Digital + paperback book	$10	One-time	Free in the US

The intro offer is $10 for the digital edition plus a free paperback shipped to US addresses, discounted from a stated regular price of $19.99. This is a one-time purchase, not a subscription, and it is one of the cheaper digital products in this category.

Because the book is a one-time purchase with no bundle tiers, there is no monthly cost to calculate the way there is with a supplement. The main things to watch for at checkout are any post-purchase upsell offers ClickBank order pages commonly show, and any shipping charge that may apply outside the US.

At $10, the financial downside of trying the book is small, and the 60-day refund window named in the company's terms page adds a reasonable safety net if the content is not useful to you.

The intro offer ships the paperback free within the US. The page does not list international shipping rates; buyers outside the US should expect to see any charge added at checkout.

Can you get a refund on The Book on Heat?

60-day window. The sales page itself does not mention a refund window. The company's Terms page (clkbooks.com terms, linked from the site footer) states refund requests are accepted within 60 days of the order date with no prior authorization required, so 60 days is used here.

Step by step: find the ClickBank receipt email, look up the order at clkbank.com and ask for a refund in writing. Our ClickBank refund guide covers returns, extra offers and auto-ship.

Which red flags did we find?

Cited research not shownThe "350 research papers" claim is not accompanied by a visible list or bibliography on the sales page itself.
Broad claim list outruns the cited scienceThe page attaches heat exposure to nearly every health outcome (digestion, hormones, aging, chronic disease) while the published research is mostly observational and concentrated on cardiovascular markers.
No refund window stated on the sales pageThe checkout page promotes the $10 offer without mentioning a return policy; the 60-day window only appears on a separate terms page linked from the site footer.

Who should buy The Book on Heat, and who should skip it?

It may suit you if

You already know and trust Brad Pilon's other work and want a reasonably priced follow-up book covering a different angle on metabolism.
You are curious about the research on sauna use, hot baths or other heat exposure and want a plain-language summary rather than reading the primary literature yourself.
You want a low-cost, one-time digital and physical book rather than a recurring supplement subscription.

Skip it if

You expect the book's claims to be individually sourced and footnoted on the sales page itself; the bibliography is not shown there.
You are looking for a proven weight-loss method backed by controlled trials on the book's specific protocol; the published heat-exposure research is mostly observational.
You have a heart condition, are pregnant or have any condition affected by heat stress; sauna and heat-exposure practices carry real risks for some people and should be discussed with a doctor first.

The Book on Heat FAQ

Is The Book on Heat legit?

It is a real book by a previously published, named author (Brad Pilon), sold through ClickBank. The content leans on a real area of research on heat exposure, though the sales page presents broader claims than that research directly supports.

How much does The Book on Heat cost?

The intro offer is $10 for the digital edition and a free paperback shipped to US addresses, down from a stated regular price of $19.99. It is a one-time purchase, not a subscription.

Does heat exposure actually help with weight loss?

Research on sauna use and hot-water immersion shows associations with improved cardiovascular and inflammatory markers, mostly from observational studies. A direct, proven weight-loss effect strong enough to rely on has not been established, and the book's own specific protocol has not been tested in a published trial that we found.
