Please read this:
Eggs, Carbs and Cholesterol
When I asked the authors for permission to include an excerpt from that in my book the highly scientific approval response I received was “feel free to quote those paragraphs. You got the idea correctly”.
Hi Alan,
I've just read your blog entry on that research AND the full paper itself.
You quote the Abstract and comment on it ...
Paper says ... "Energy intake decreased in both groups from 10,243 ? 4040 to 7968 ? 2401 kJ compared with baseline. All subjects irrespective of their assigned group had reduced body weight and waist circumference"
Your comment on that ...[The reduced-carb diet worked for ALL of them, regardless of egg intake].
No Alan,the snippet you quote says the study groups reduced their calorie intake by 20 %. So your comment should read "the reduced CALORIE diet worked for all of them." Its a fair bet the weight reduction was a result of lowering calories as much as switching to reduced carbs. ( A Calorie is a Calorie).
But back to the Abstract you quote in your blog. The Abstract is a shocker and it is difficult to see how they could derive that Abstract from the actual results reported in the full Paper.
1. The Abstract you make so much of states that LDL was unchanged. Whaaaat ? Table 3 in the full paper shows that LDL went up by 13% in the EGG group and by 12% in the SUB group. The claim made for LDL in the Abstract is quite simply a bare-faced terminological inexactitude. It is astonishing how false reporting like that got through peer review and an Editor.
2. HDL did go up by 20% in the EGG group but not in the SUB group.
THis is NOT a good point in favour of the EGG diet - it simply means that the three eggs a day did impose a strain on the body and it had to run faster to compensate for the increased cholesterol burden imposed by the eggs. And remember these were fasting lipid panels so the raised HDL was the morning after "after-glow" of considerable cholesterol spikes the day before.
3. The Abstract does not mention the effects of the 3 egg diet on Total Cholesterol. Table 3 shows that Total Cholesterol went up in the EGG group over the 12 week period. TC went up by 2% in the Egg group. Over a year that would probably turn out at about a 10% increase in TC ( given the cumulative increases). Oops that's a negative outcome - better NOT mention it in the Abstract !
4. There are several ludicrous mistakes in Table 3 ( which summarises the main results of the, short,12 week trial ). For example the TC of the SUb group started at 188.3 and ended at 187.3. Mutungi et al state in Table 3 that this is a +1.00 increase in TC. Well now, I don't know which Planet Mutungi et al come from, but here on Planet Earth a DECREASE from 188 to 187 is generally reckoned to be a fall of -1.00.
Flawed,slipshod rubbish - were the Peer reviewers and editor asleep ?
5. Perhaps ther most laughable and flawed part of this paper is the testing of lipids. It is well established that lipids rise ( especially LDL which has to shift dietary cholesterol from the stomach) up to three hours after a meal and subside by five hours post prandial. And it is the post prandial LDL spikes that are now thought to be a big factor in cvd. Obviously to test the effect of three eggs on cholesterol you would need to test at the three hour mark.
So what do the numpties conducting this research, Mutungi et al, do ?. They do morning tests after a 12 hour fast. Brilliant ! You wait till you know the effects of the eggs have long gone and then test to see what effect they have. Er..........yeah .........right.
They even take two fasting lipid panels a week to even out any spikes ....Heeeeeelp .... its the post-prandial lipid spikes you should be looking for if you want to test the effects of 3 eggs a day !
No its poor, flawed, badly written up research. I think you should read the full paper and then take it out of your blog. I don't think anyone on this support group should base decisions about their health and life on shoddy research like this.
