nutrition question

Post by biology_06er » Wed Dec 01, 2010 11:21 am

Hi there,

Sorry if this question is obvious but I'm really confused as I'm reading this article:

Say you have a low-energy meal (0.5MJ) and a high-energy meal (5.0MJ) and both contain around 30% fat, 50% CHO and 15% protein. How is it is they have the same macronutritent compositions yet one is considered "low" and the other considered "high" energy. Or have I misread what they mean?

Thanks

what about the amount of meal?

Cis or trans? That's what matters.

LOw energy meal: 1Burger
High energy meal: 10 burgers identical to the one above.
In terms of relative composition, they are identical, in terms of energy, quite different.
