The Scorch Protocol works because it pushes the body hard: a deep dry fast, a staged refeed, and thyroid hormone (T3) to restart a suppressed metabolism. That same intensity makes it dangerous for some people. This page is the honest version of who should not attempt it, or who needs medical supervision before they do.
This is educational information, not medical advice, and it cannot account for your full history. Talk to a physician who knows your case before starting any fast, supplement, or medication change.
Do not attempt the fasting protocol if any of these apply
Pregnant or breastfeedingFasting at this depth deprives a developing baby and an infant of nutrients. This is an absolute no.
Type 1 diabetesThe risk of life-threatening blood sugar and ketone swings is too high. People with type 1 diabetes were turned away.
Active or advanced heart disease, heart damage, or significant arrhythmiaDeep fasting and T3 both stress the heart. With existing cardiac disease that stress can be dangerous.
Active kidney disease or kidney failureA waterless fast concentrates everything the kidneys must process. Compromised kidneys cannot safely handle it.
Underweight (BMI under 18), or an eating disorder, current or pastThere is no fat reserve to fast on, and the protocol can be a serious trigger for disordered eating. This is not the tool for you.
An active acute infection or illnessYour body needs fuel to fight an active infection. Wait until you have recovered before considering a fast.
Under 18Disrupting metabolism during developmental years carries risks that are not worth taking.
Get a doctor's clearance and supervision first if any of these apply
These are not automatic disqualifiers, but they change the risk enough that you should not proceed alone.
On diuretics, anticoagulants, insulin, or any medication that needs close titrationFasting and refeeding shift fluid, electrolytes, and blood sugar fast. These drugs may need to be adjusted by your prescriber, never on your own.
Type 2 diabetes on medicationPossible for many people, but only with medical supervision to manage medication and blood sugar through the fast and refeed.
POTS or dysautonomiaFluid shifts and T3 can provoke unpredictable responses. Proceed only with guidance and close monitoring.
A history of arrhythmia, or known osteoporosisT3 therapy in particular needs extra caution and monitoring in these cases.
A heavy medication load, or you are not in the right headspaceA complex medication picture, or a mindset that is not ready, can make deep fasting too risky. Sort this out first.
If you are cleared and ready, the Decision Logic Tree will help you find the right starting point, and Phase 1: Preparation covers the baseline tests and steps that make the fast safer.
