Most protein bars, are made for protein companioes by candy bar manufacturers.Its a known fact.
Protein companies, dont have the equiptment or the ability to make bars, so they are out sourced to well known candy bar companies.
The problem with protein bars, isnt the fat or carbs.Its the Hydrolised Collagen protein ( protein from animal skin, cartlidge,bones hoaves etc,etc) The Soy Protein and Sweet dairy Whey they use as there protein sources.
To make matters worse,when they make these bars, they use heat, which denatures, and damages the protein.Making it totally useless for rebuilding and recovering muscle.
Protein bars are not bad as a snack but when I eat them I dont count them as a protein source.They are simply a tasty snack.IF you choose to eat protein bars just know that, they are not as good as a reputable protein powder.
Plus they contain a ton of glycerin and a lot of sugar which can make you have a spike, then a severe drop in insulin.
Making you feeling tired and drained.
