New investigation shows why Oprah, Jessica Simpson, among others struggle with weight

For many, Oprah and Jessica Simpson have shone while in the spotlight -- but that spotlight has also lit up their dieting battles. Oprah is popular for lugging a son's or daughter's red wagon onto your ex stage, filled with "fat" representing her weight-loss. Slim in her shorts, she vowed she'd do not ever regain that weight... along with a year later, her significant bulk belied her ideas. Jessica Simpson has surprised us in her Daisy Dukes... and dismayed us inside her dark dresses donned to cover her weight gain.

Now, a good solid study reveals just why numerous celebrities and "real folks" have fat loss battles. Published in the popular England Journal of Remedies this week, the study showed when people lose at the least 10 percent of your weight, then diet to keep their weight loss, not one but two problems occur: they experience hormonal shifts that provide an incresaed appetite NOT TO MENTION their metabolisms slowed. The concern is why these challenging changes continue, turning it into so difficult for stars like Oprah and Jessica to sleep in at their lower dumbbells.
