Mostly false Certainty of evidence: low 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.
Conclusion: Early type 2 diabetes can go into remission with substantial weight loss, but the claim that the Tayebat system cures diabetes, including long-standing insulin-treated 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: low – Further research is likely to change the assessment considerably.

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). The archive itself recommends diet and weight loss before insulin escalation (C-INS-11).

3. What is wrong or exaggerated?

DiRECT used total diet replacement (825-853 kcal/day) with structured support and excluded people on insulin and with diabetes >6 years; remission depended on weight loss, not on avoiding particular 'forbidden' foods (I-FAST-12). Remission mostly waned: at 5 years 10% vs 5% of the original randomised groups were in remission, 13% of the extension participants, and among those who had lost more than 10 kg remission fell from 78% at year 2 to 14% at year 5 (I-FAST-14). This does not support 'cure' or stopping insulin after 30 years. 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 (remission of early type 2 diabetes with major weight loss); partly I-FAST-14 (some long-term remission).

6. Which studies contradict it?

I-INS-03, I-ODD-16; I-FAST-14 (remission mostly not durable; people on insulin 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 an RCT (DiRECT: 46% at 1 year), but DiRECT excluded people on insulin and with diabetes for more than 6 years, and remission depended on weight loss, not on avoiding particular foods (I-FAST-12 to I-FAST-14). (b) Cure of type 1 diabetes or long-standing insulin-treated diabetes by diet is contradicted by guidelines (I-ODD-16). (c) The Tayebat system has not been tested. The claim as made, and the case used to illustrate it, fall under (b) and (c). Certainty is low because no study has tested the system itself.

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).

Regional scope of the claim
general (biological/medical)
Last reviewed
25 October 2026 provisional

In plain language

A British trial showed that almost half of people with recent type 2 diabetes who lost a lot of weight could stop all diabetes medicines for at least a year. Some kept this for five years. This worked through weight loss, under medical supervision. It does not apply to type 1 diabetes, and the specific Tayebat diet has never been tested.

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 weight loss, but the claim that the Tayebat system cures diabetes, including long-standing insulin-treated 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.
