The bar that i'm going to be using on this week does contain glycerine. So what? I count the carbs. 35g of carbs per bar is not going to make me fat if I eat at maintainance for the week.
Again, do what you want but ingesting 35 grams of glycerin 3 or 4 times per day will basically spike your insulin response through the roof each time you eat one which results in favorable environment for fat storage. It's not just total calories per day that makes the difference, its the type of calories you eat. Read any one of Berardi's articles on this site for a more thorough explanation.
The bar doesn't contain any gelatin so at least the protein it contains does have biological value. The bar also contains some potassium carbonate and will not produce as much as an unfavourable PRAL score as a meal consisting of beef jerky and nuts.
You're missing the forest for the trees. Let's do a survey here. What's much more important? The macronutrient breakdown/types of you're food or PRAL score? If you say PRAL score (i.e. measures the acidity of a meal), go ahead and reread every one of Berardi's articles and come back to talk to me.
During this week I have nowhere to refrigerate my food so I can't take my own supplies (I am taking lots of nuts to make sure I get enough fats).
Excuses for not making better food choices!
Finally, correct me if I'm wrong but I haven't seen beef jerky or those tuna packs in the UK so I couldn't do that anyway!
I don't care where you're from. I gave you a few meal examples to take with you. The list wasn't meant to be exhaustive. There are additional choices. But again, if you're completely in a state of bliss eating you're glorified candy bars, have fun!
