A recent article published in the International Journal of Obesity showed that the previous notion of limiting eggs because they can increase cholesterol is no longer an acceptable fear. In fact eggs can help one lose weight!
To test the hypotheses that an egg breakfast, in contrast to a bagel breakfast matched for energy density and total energy, would enhance weight loss in overweight and obese participants while on a reduced-calorie weight loss diet.
Otherwise healthy overweight or obese participants were assigned to Egg (E), Egg Diet (ED), Bagel (B) or Bagel Diet (BD) groups, based on the prescription of either an egg breakfast containing two eggs (340 kcal) or a breakfast containing bagels matched for energy density and total energy, for at least 5 days per week, respectively. The ED and BD groups were suggested a 1000 kcal energy-deficit low-fat diet, whereas the B and E groups were asked not to change their energy intake.
After 8 weeks, in comparison to the BD group,
the ED group showed a 61% greater reduction in BMI,
a 65% greater weight loss ,
a 34% greater reduction in waist circumference (P<0.06) and
a 16% greater reduction in percent body fat (P=not significant).
No significant differences between the E and B groups on the aforementioned variables were obtained.
Further, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides, did not differ between the groups.
- But the added bonus of the study is the fact that eggs did not have any effect on the blood cholesterol level suggesting that it is really the intake of Saturated fat in the diet found in pastries, cakes and cookies that is harmful to the body!
- The results of the study were further confirmed in a similar finding from the University of Surrey research group which showed a similar no effect on cholesterol level with intake of 2 eggs per day for 6 to 8 weeks.
