Doing an iifym slow bulk, and its pretty easy counting the calories for most food that can be measured by volume, or if it has the nutrition right on the label and i can easily count the servings. But often times i find myself guessing about how much meat ans other things like that weigh. Usually what i do is jusf take the total net weight of the product and try to divide it into visibly similar portions, then calculate from there. So say i bought a pound of ground beef, i just form 3 burger patties that look about the same size, and i just count each one as 5.33 ounces. Also there are things like fruit. I count every apple or banana as one "large" piece... however theres no way for me to know the exact weight or size. I know that at most i'm never that far off since my weight gain has been consistent for the most part... but just wondering if it would be a good idea to get one, and any recommendations on certain brands, since there are times i do come up short of my goal. I think the problem i have is i tend to overestimate when i need to guess weight of food.
