Claimed mechanism

Loss of the 40 ml bile reservoir reduces fat digestion.

Claimed health effect

Fat malabsorption; need to increase fat intake.

People after cholecystectomy

اي اكل حضرتك فيه ضرب لا اللي بيشيل المراره ما ياخدش ما ياخدش املاح مراريه المراره اما اتشالت عملت مشكله واحده بس ان انت الاملاح المريه في مخزون 40 ملي بيبقوا

People whose gallbladder has been removed should not take bile salts; removing the gallbladder causes one problem: the loss of the bile-salt store (about 40 ml).

Scientific assessment

Unclear / insufficient evidence – The data do not allow an assessment either way.

Certainty of evidence: very low – Any assessment is very uncertain.

1. What was claimed?

Eat more fat after cholecystectomy.

2. What is demonstrably correct?

The gallbladder stores and concentrates bile; after removal bile flows continuously (basic physiology).

3. What is wrong or exaggerated?

No evidence was identified for the absorption percentages he cites or that doubling fat intake is beneficial; two studies in a systematic review linked post-cholecystectomy diarrhoea to high-fat intake (A-ORG-09).

4. What remains unclear?

Not systematically searched. In a second passage of the same video he says people without a gallbladder should not take bile salts and that removal causes only one problem, the loss of the bile store (about 40 ml). That the gallbladder stores bile is basic physiology; the volume he gives is plausible but was not checked against a source here. 'Only one problem' is an oversimplification: post-cholecystectomy diarrhoea occurred in 13.3% of patients in a systematic review (A-ORG-09). No evidence was searched on bile-salt supplements after cholecystectomy; we make no judgement on that advice.

5. Which studies support it?

None.

6. Which studies contradict it?

A-ORG-09 (indirect): diarrhoea after cholecystectomy is a common side effect (13.3%), and two included studies associated it with high-fat meals or not following a low-fat diet (Yueh 2014; Jasim 2018), which runs against advice to eat more fat.

7. What applies to Germany and Europe?

Most cited cohorts are Scandinavian (Denmark, Sweden) and directly European; RCTs from the UK and Finland are directly transferable. Guidelines in Europe also emphasize defined indications (not verified here in detail).

8. What is known about Egypt?

No Egypt-specific data on rates or outcomes of tonsillectomy, cholecystectomy, hysterectomy, splenectomy or thyroid surgery were identified in this review.

9. What practical conclusion is appropriate?

Dietary advice after cholecystectomy should come from a clinician or dietitian.

Assessment details

Rationale for certainty of evidence

No study on fat intake advice after cholecystectomy was identified in this review; the specific percentages he gives (60%/40% absorption) are not sourced.

Source quality

Mechanistic reasoning with unsourced numbers.

Regional transferability

n/a

Individual exceptions

Some patients develop bile-acid diarrhoea after cholecystectomy (13.3%, A-ORG-09), which could plausibly worsen with high fat intake (not tested here).

general (biological/medical)
Last reviewed
25 October 2026 provisional

In plain language

Elawady advised people without a gallbladder to eat about twice as much fat. We found no evidence for this advice or for the absorption numbers he gave. About 13% of people get diarrhoea after gallbladder removal, and two studies found this diarrhoea more often in people eating high-fat meals, although no trial has tested the advice directly.

Studies contradicting or limiting the claim (1)

  • Diarrhoea after gallbladder removal

    Systematic reviewcited by the Tayebat archivefull text checked

    About 13% of patients developed diarrhoea after the operation.

    After gallbladder removal fat absorption falls, so patients should eat more fat (e.g., 200 g instead of 100 g) such as butter and ghee.

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

General scientific assessment

Unclear / insufficient evidence Unproven advice.

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