This workout plan and the nutrition seem sensible and doable. What was the food delivery service Jessica used?

"She makes it easy, by using the 5-factor diet food delivery service, available only in the LA area, at"

It would be simpler if we all had personal trainers like Celebs do,,,, but we don't .

Would u pliz give us other tactics on how to lose weight with NORMAL people?

Thanx ,

That's a hella lot of food…how did they manage to find her such rich foods that only equate to 1300 calories a day? Seems a bit too good to be true.


Erin January 3, 2008 at 10:49 am

I'm with Melissa on this one, how could all that food be only 1300 calories? Mind you, they didn't really specify quantities. . .still, may have to research this one more closely :) Jessica looks healthy and beautiful, so there's gotta be something there!


Elizabeth January 10, 2008 at 4:04 am

what that sounds like waaay to much food to only be like 1300 calories a day


Billy January 31, 2008 at 9:27 am

it is a lot of food… but it's the right food so it is low in calories… I used to do a similar plan but ate 6 times a day at 1500 cal. high protein to increase muscle mass, but low cal. to force the body to eat what it had already… looking into trying this program because it's similar to what I've done before and had it work… until I fell off the wagon (ex girl friend started to cook for me, her food choices).


Bex March 20, 2008 at 2:16 pm

It is a lot of food but remember her portions will be small and the names they've given some of the dishes are pretty elaborate, making it sound more filling an therefore interesting.

She looks great though an this is far more sensible than the diets most other celebs go on!

Eat WAY less, move WAY more. The world is obsessed with food. I am below my ideal BMI and I think I could still lose weight. And healthy women, like me, get labeled as having eating disorders. Something wrong with the world.

I love you Jess!

The subsequent time I read a site, I hope that it doesnt disappoint me as a lot as this one. I mean, I know it was my option to read, but I truly thought youd have one thing fascinating to say. All I hear is really a bunch of whining about something that you could fix if you werent too busy searching for attention.
