Mostly false Overinterpreted Certainty of evidence: moderate provisional C-DIAB-03

Diabetes can be cured by following the Tayebat system without medication, illustrated by a patient who stopped insulin after 30 years of insulin use.

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 mostly false. Substantial weight loss can put early type 2 diabetes into remission in many people, but this is remission rather than cure, it fades in many, and it does not apply to type 1 diabetes or to most long-standing insulin-treated diabetes; the Tayebat system itself has never been tested.
Conclusion: Early type 2 diabetes can go into remission with substantial, supervised weight loss, but this is not a cure and does not apply to type 1 or most long-standing insulin-treated diabetes; the claim that the Tayebat system cures diabetes is not supported.

Scientific assessment

Mostly false – Essential parts of the statement are not supported by the evidence or are strongly exaggerated.

Certainty of evidence: moderate – Further research may still affect the assessment.

1. What was claimed?

Diet cures diabetes, as shown by patients who stopped insulin on the system.

2. What is demonstrably correct?

DiRECT: remission (HbA1c <6.5% off all drugs) in 46% vs 4% at 12 months; 86% of those losing >=15 kg (I-FAST-12); 36% vs 3% at 24 months (I-FAST-13). DIADEM-I (Qatar, people from the Middle East and North Africa, diabetes <=3 years): remission 61% vs 12% after an intensive diet programme (I-DIAB-101). A meta-analysis of 18 nonsurgical RCTs found remission about six times more likely with nonpharmacological programmes (RR 5.80) (I-DIAB-103). ADA 2026 states that sustained loss of >10% body weight may lead to remission (I-DIAB-113). The archive itself recommends diet and weight loss before insulin escalation (C-INS-11).

3. What is wrong or exaggerated?

Remission trials used structured low-energy programmes with medical supervision and enrolled mainly people with recent, non-insulin-treated type 2 diabetes; remission depended on weight loss, not on avoiding particular 'forbidden' foods (I-FAST-12, I-DIAB-101, I-DIAB-103). Remission mostly waned: at 5 years 10% vs 5% of the original DiRECT groups were in remission (I-FAST-14); in Look AHEAD only 3.5% stayed in remission for 4 years (I-DIAB-102). The accepted term is remission, not cure, and it requires continued follow-up (I-DIAB-104). Before insulin existed, diet and fasting could not keep insulin-deficient diabetes alive: most children died of diabetic coma within months to years and Allen wrote that 'the diabetes is not cured' (I-INS-101). Type 1 diabetes cannot be cured by diet (C-INS-07). The Tayebat system has not been tested; the cases cited are not verifiable.

4. What remains unclear?

Whether the Tayebat dietary rules produce sufficient weight loss in practice.

5. Which studies support it?

I-FAST-12, I-FAST-13, I-DIAB-101, I-DIAB-103, I-DIAB-113 (remission of early type 2 diabetes with major weight loss); partly I-FAST-14, I-DIAB-102, I-DIAB-104 (some long-term remission; definition).

6. Which studies contradict it?

I-INS-101 (pre-insulin natural history), I-INS-03, I-ODD-16; I-FAST-14 and I-DIAB-102 (remission mostly not durable; people on insulin largely not studied).

7. What applies to Germany and Europe?

German guidance accepts remission through weight reduction as a goal in early type 2 diabetes.

8. What is known about Egypt?

Lifestyle-based remission programs are less established; supervision is needed when reducing drugs.

9. What practical conclusion is appropriate?

Early type 2 diabetes can go into remission with substantial weight loss under medical supervision; medicines are reduced step by step with monitoring. This does not apply to type 1 diabetes.

Assessment details

Rationale for certainty of evidence

Split: (a) remission of early type 2 diabetes through substantial weight loss is shown in RCTs (DiRECT 46% vs 4%; DIADEM-I in a Middle Eastern population 61% vs 12%) and a 2025 meta-analysis of 18 RCTs (I-DIAB-103), but mostly in people with short diabetes duration, without insulin, under strict supervised protocols, and remission often fades (I-FAST-14, I-DIAB-102). (b) Cure of type 1 diabetes or long-standing insulin-deficient diabetes by diet is contradicted by natural-history data from the pre-insulin era (I-INS-101) and by all guidelines. (c) The Tayebat system has not been tested. Certainty is moderate (raised from low): the boundaries of diet-induced remission are now well defined by randomised evidence; the only indirectness is that the specific system is untested.

Source quality

Own words; anecdotal cases.

Regional transferability

DiRECT conducted in UK primary care; transferability to Egypt plausible if weight loss is achieved.

Individual exceptions

Remission is most likely with short diabetes duration (<6 years), no insulin, and large sustained weight loss (>10-15 kg).

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?

Early type 2 diabetes can go into remission (not cure) with substantial supervised weight loss; type 1 diabetes and long-standing insulin-deficient diabetes cannot be cured by diet; the Tayebat system has not been tested.

Why some studies weigh more

RCTs define the boundaries of remission (early T2D, weight loss, supervision); historical and guideline evidence define the impossibility for insulin-deficient diabetes; anecdotes carry no weight.

Is a causal relationship established? Yes, established Weight loss causes remission in early T2D (RCTs with dose-response); absence of insulin causes death in insulin-deficient diabetes (historical natural history).

Remaining uncertainty

Long-term durability; effect of the specific Tayebat rules (untested); the illustrative patient's diabetes type is unknown.

Justified conclusion

Mostly false; true only for remission of early type 2 diabetes via weight loss.

Why do studies seem to disagree?

Remission trials (supporting) and historical/guideline evidence (contradicting) concern different populations: early T2D with preserved beta-cell function versus insulin-deficient diabetes. Ketosis-prone T2D (I-INS-128) shows that some people who present with DKA can stop insulin, but only under supervision and based on phenotype.

Does this depend on the country?
General biological effects
Insulin physiology, autoimmune type 1 diabetes and ketoacidosis are universal human biology.
Eating habits
DIADEM-I shows remission is achievable in people from the Middle East and North Africa with structured weight loss.
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.

Statistical re-check
  • Absolute remission difference and NNT – 49 percentage points (35.5-62.5); NNT about 2; OR 12.03 overstates the relative effect (RR about 5.1) recalculated
  • Absolute remission difference – Year 1: 9.5 points (NNT about 10.5); year 4: 5.3 points (NNT about 19) recalculated
  • Absolute remission difference – 42 points (33.4-50.6); NNT about 2.4 recalculated
Certainty of the overall evidence (GRADE, simplified)
Main outcome
Remission of diabetes off medication with dietary intervention (claim as stated, incl. insulin-treated/type 1)
Starting level
high (randomised trials)
Reasons for downgrading
  • indirectness (Tayebat system untested; trials in early T2D only)
Result
moderate

History of the verdict
  1. 25 October 2026 · Phase 1 · Initial assessment: Mostly false (low)
  2. 26 October 2026 · Phase 4 (systematic evidence review) · Verdict changed: Mostly false (low) → Mostly false (moderate)
    Verdict unchanged. Certainty raised from low to moderate: a 2025 meta-analysis of 18 RCTs and the Middle Eastern DIADEM-I trial define clearly that remission is limited to early type 2 diabetes with major weight loss, while historical natural-history data show that diet cannot replace insulin in insulin-deficient diabetes. The only remaining indirectness is that the Tayebat system itself is untested.

In plain language

Trials in Britain and Qatar showed that about half or more of people with recently diagnosed type 2 diabetes who lost a lot of weight on a structured programme could stop all diabetes medicines for at least a year. Many relapsed in later years. This worked through weight loss and under medical supervision. Before insulin was discovered, diet alone could not keep children with type 1 diabetes alive. The specific Tayebat diet has never been tested.

    Most children died of coma within months to years; 43% of Allen's cases were dead by 1917; four died of starvation; diabetes was not cured.

    How large was the observed effect?

    43% mortality within a few years (Allen's series).

    What do the results mean in everyday life?

    Diet and fasting alone cannot keep insulin-deficient diabetes alive; insulin changed this.

    What are the study's limitations?

    Historical, uncontrolled data; diabetes types not distinguished.

    What does it say about Elawady's specific claim?

    Contradicts claims that diet can replace insulin or that ketoacidosis does not kill.

    Do the results apply to Germany and Europe?

    Universal biology.

    What can explicitly not be concluded from this study?

    Cannot give exact survival curves or separate type 1 from type 2 cases.

    Randomised controlled trialindependent cross-checkabstract checked★ key study

    About 1 in 9 people reached remission in the first year with an intensive lifestyle programme, but only 3.5% stayed in remission for 4 years.

    Remission possible (11.5% year 1) but rarely sustained (3.5% for 4 years).

    Does the study support the specific claim? Partly · Methodological quality: high · Certainty of evidence: see overall assessment of the claim

    Original publication · Scientific details

    Study explained simply
    What did the researchers want to find out?

    Measure remission in a lifestyle trial.

    How was the study done?

    Analysis of a large RCT.

    How many people, animals or samples were studied?

    4,503 adults.

    What was actually found?

    11.5% vs 2.0% (year 1); 3.5% sustained 4 years.

    How large was the observed effect?

    NNT about 10 (year 1).

    What do the results mean in everyday life?

    Lifestyle helps, but lasting remission is uncommon.

  • What 'remission' of type 2 diabetes means

    Riddle MC et al.. Diabetes Care 2021 · PMID 34462270 · DOI 10.2337/dci21-0034
    Guideline / position statementindependent cross-checkabstract checked★ key study

    Remission means HbA1c below 6.5% at least 3 months after stopping diabetes drugs; it is not called a cure and needs ongoing checks.

    Remission (not cure) of T2D is recognised; requires follow-up.

    Does the study support the specific claim? Partly · Methodological quality: high · Certainty of evidence: see overall assessment of the claim

    Original publication · Scientific details

    Study explained simply
    What did the researchers want to find out?

    Define T2D remission.

    How was the study done?

    Expert consensus.

    How many people, animals or samples were studied?

    Not applicable.

    What was actually found?

    HbA1c <6.5% >=3 months off drugs.

    How large was the observed effect?

    Not applicable.

    What do the results mean in everyday life?

    Remission is possible but needs follow-up.

    What are the study's limitations?

    Consensus.

    What does it say about Elawady's specific claim?

    Qualifies 'cure'.

    Do the results apply to Germany and Europe?

  • Who can stop insulin after a first episode of ketoacidosis?

    Raubenheimer PJ et al.. Diabetologia 2024 · PMID 38240751 · DOI 10.1007/s00125-023-06067-3
    Cohort studyindependent cross-checkabstract checked★ key study

    In Cape Town, about a quarter of adults could stay off insulin for 5 years, mostly those with a type 2-like profile; people with type 1 antibodies rarely could.

    Insulin independence depends on diabetes type and beta-cell reserve, not on a diet.

    Does the study support the specific claim? Partly · Methodological quality: moderate · Certainty of evidence: see overall assessment of the claim

    Original publication · Scientific details

    Study explained simply
    What did the researchers want to find out?

    Find predictors of insulin independence after DKA.

    How was the study done?

    Prospective cohort with supervised weaning.

    How many people, animals or samples were studied?

    88 adults.

    What was actually found?

    46% at 1 year, 26% at 5 years off insulin; antibodies predict dependence.

    How large was the observed effect?

    OR 11.5 (acanthosis); 0.10 (antibodies).

    What do the results mean in everyday life?

    Stopping insulin is possible for some people with a specific type 2 profile, under medical supervision only.

    What are the study's limitations?

    Small study.

    What does it say about Elawady's specific claim?

    Partly qualifies 'nobody can stop insulin'; contradicts stopping it in type 1.

    Do the results apply to Germany and Europe?

    Phenotype rarer in Europe.

    What can explicitly not be concluded from this study?

    Cannot support stopping insulin without testing and supervision.

Regional context

Germany / EU

German guidance accepts remission through weight reduction as a goal in early type 2 diabetes.

Egypt

Lifestyle-based remission programs are less established; supervision is needed when reducing drugs.

What applies in my country?

General scientific assessment

Mostly false Early type 2 diabetes can go into remission with substantial, supervised weight loss, but this is not a cure and does not apply to type 1 or most long-standing insulin-treated diabetes; the claim that the Tayebat system cures diabetes is not supported.

This statement concerns biological or medical relationships. The scientific assessment above applies regardless of the country; country-specific food data do not change it.
