False Scientifically refuted Certainty of evidence: high provisional C-INS-02

Injected insulin halts the Krebs cycle, blocks protein and DNA synthesis, starves the brain of glucose and causes seizures and blood clots.

Safety note: Do not stop or reduce insulin on the basis of this claim. In type 1 diabetes and other insulin-deficient states, stopping insulin leads within hours to days to diabetic ketoacidosis, which is life-threatening. Medically accepted position (ADA Standards of Care 2026): insulin treatment is essential for people with type 1 diabetes; people on intensive insulin therapy should not stop basal insulin even when not eating. Any change of diabetes medication should be made together with the treating physician.
In short: This claim is false. Human experiments show the opposite: lack of insulin reduces the cell's energy (ATP) production and increases protein breakdown, while insulin supports both; the only true part is that too much insulin causes hypoglycaemia, which can lead to seizures.
Conclusion: The Krebs-cycle and DNA claims are false; the only true part is that insulin overdose can cause dangerous hypoglycaemia.

Injecting insulin disables the Krebs cycle and with it ATP production (oxidative phosphorylation), so the body 'freezes' and cannot produce heat.

Scientific assessment

False – The statement contradicts the robust evidence.

Certainty of evidence: high – Further research is very unlikely to change the assessment.

1. What was claimed?

Insulin stops the Krebs cycle, blocks protein and DNA synthesis and causes seizures and clots.

2. What is demonstrably correct?

An overdose of insulin causes hypoglycaemia, which can cause seizures and loss of consciousness. Severe hypoglycaemia was more frequent with intensive treatment in ACCORD, ADVANCE, VADT, UKPDS and DCCT (A-INS-01, I-INS-01, A-INS-03, A-INS-16, I-INS-03) and was associated with later vascular events and death (A-INS-14, A-INS-15), although in ADVANCE it occurred mainly under sulfonylurea-based therapy in people not on long-term insulin (A-INS-15).

3. What is wrong or exaggerated?

Insulin does not stop the Krebs cycle; it increases glucose uptake into muscle and fat (via GLUT4) and promotes glucose oxidation and storage. Insulin is anabolic: it stimulates protein synthesis and inhibits protein breakdown; insulin deficiency (type 1 diabetes, ketoacidosis) causes muscle wasting. No study presented by the archive shows insulin causes clots at therapeutic doses. The hypoglycaemia studies the archive cites contain no evidence on the Krebs cycle, protein or DNA synthesis or clots: in ACCORD, of 431 adjudicable deaths hypoglycaemia was definitely involved in 1 and probably in 3, and excess hypoglycaemia explained only about 5 of 57 excess deaths in the intensive arm (A-INS-14); in ADVANCE associations were non-specific (also with respiratory, digestive and skin disease), without a dose-response, and the authors judged hypoglycaemia as likely a marker of vulnerability as a cause (A-INS-15).

4. What remains unclear?

Whether severe hypoglycaemia itself causes cardiovascular events or mainly marks frail patients is unresolved (A-INS-15).

5. Which studies support it?

None for the mechanistic claims. Mixed: A-INS-14, A-INS-15 (support only the kernel that severe hypoglycaemia under glucose-lowering treatment occurs and marks higher risk).

6. Which studies contradict it?

Standard biochemistry (I-INTB-01); I-INS-116 (insulin deprivation lowers muscle mitochondrial ATP production and raises protein breakdown and ketones in T1D); I-INS-07 and I-INS-08 (insulin is the cornerstone of treating ketoacidosis, a state of insulin deficiency with catabolism); I-INS-03; A-INS-14 and A-INS-15 (hypoglycaemia mostly a marker, rarely a direct cause of death).

7. What applies to Germany and Europe?

European (EASD) and German (DDG) guidance follow the same evidence base as the ADA/EASD consensus: individualised HbA1c targets, insulin as mandatory therapy in type 1 diabetes, and SGLT2 inhibitors/GLP-1 receptor agonists for people with cardiovascular or kidney disease. No country-specific difference changes the assessment.

8. What is known about Egypt?

Egypt has one of the highest diabetes prevalences in the region; the same drug classes and insulins are used. Access barriers and cost may make advice to stop medication attractive, which increases the practical risk of this claim. No Egypt-specific evidence changes the assessment.

9. What practical conclusion is appropriate?

The real risk of insulin is hypoglycaemia, which is managed by appropriate targets, dosing, glucose monitoring and education, not by stopping insulin.

Assessment details

Rationale for certainty of evidence

Textbook physiology: insulin stimulates glucose uptake and oxidation in muscle and fat and is an anabolic hormone that promotes protein synthesis; no evidence that insulin stops the Krebs cycle. The only correct kernel (seizures from insulin-induced hypoglycaemia) is well documented.

Source quality

Archive paraphrase plus own words in machine transcript.

Regional transferability

Universal physiology.

Individual exceptions

Hypoglycaemia (too much insulin relative to need) can cause confusion, seizures and, rarely, death; this is a dosing problem, not a property of insulin at physiological levels.

What speaks for the claim?

What speaks against the claim?

What does the overall evidence say?

Editorial assessment based on the studies above – not itself a study result.

Which position is better supported?

Insulin promotes glucose oxidation, ATP production and protein synthesis; its real risk is hypoglycaemia from excess dosing.

Why some studies weigh more

Human physiology experiments and textbook biochemistry contradict the mechanism; only the hypoglycaemia kernel is supported.

Is a causal relationship established? Yes, established Insulin overdose causes hypoglycaemia and seizures; insulin does not stop the Krebs cycle (insulin deficiency impairs it).

Remaining uncertainty

Whether severe hypoglycaemia causes cardiovascular events or marks frailty.

Justified conclusion

False, except the hypoglycaemia kernel.

Does this depend on the country?
General biological effects
Insulin physiology, autoimmune type 1 diabetes and ketoacidosis are universal human biology.
Eating habits
Egyptian and European diets differ, but no dietary pattern replaces insulin in insulin-deficient diabetes.
Origin of the food
Not relevant.
Contaminants
Not relevant.
National production conditions
Not relevant.
Legal rules
Insulin is an essential medicine (WHO list) in Egypt and the EU; prescription rules not relevant to the scientific question.
Actual monitoring data
Egyptian/Middle Eastern data show severe DKA is common at presentation in children (I-INS-115, I-INS-114); no data on outcomes among Tayebat followers.

A regional difference that changes the conclusion is not supported by robust data.

In plain language

Insulin does not stop the cell's energy engine. It helps muscle and fat take up sugar and it helps build protein. The real danger of insulin is a dose that is too high, which makes blood sugar fall too low; this can cause confusion and seizures. That risk is handled by careful dosing and checking blood sugar.
