@aidan,
Welllll, how big is a sliver, etc.?
Serving sizes are, like I said, totally out of whack for so many Americans. We are conditioned to feel we need to get our money's worth, so we supersize everything. Or it's supersized for us.
RP and I eat at a diner on occasion. The food is decent and there are things I can have. BUT, the food comes out not on plates but on platters. This is your individual meal. ON A PLATTER.
It's crazy. I take half home with me.
Being a cook/chef is very difficult for folks trying to lose weight or manage diabetes, because of the tasting you describe. It's a little of this and a little of that. But you do it fifty times in a day sometimes. And yeah, that adds up.
One hint: a gram of fat is 9 calories.
Always. This is pure fat I'm talking about, as in butter, margarine, lard, avocado, bacon, most nuts, whatever. A gram of carbs (pure), is 4 calories. As in, rice, potatoes, peas, pasta, chestnuts. A gram of sugar is the same 4 calories (as in, sugar, honey, jelly, syrup). Those are the building blocks of food. So if you get an idea of the serving size you've eaten, and how much is fat, how much is carb and how much is simple sugar, you can figure out an approximation of the calories. But keep in mind that fiber is indigestible and water is a large component of all foods.
If you ate, let's say, 100 grams (close to 3/4 cup) of potatoes, it
should be, yes, 300 calories. But it's not. It's actually closer to 100 calories. Why? Because there's water and fiber in there. 100 grams of potatoes is really more like 22 grams of carbs (you'd think potatoes would be 100% carbs, yet they're not). 22 * 4 = 88. According to
www.sparkpeople.com, 100 grams of baked potato (so this is plain, but no skin) is 93 calories. The extra five calories in there is probably a gram or so of sugar.
1 gram = 0.0353 ounces (this is not a perfect measurement as grams are supposed to be solid and ounces are liquid but it's close, and in food those terms are interchanged all the time -- incorrectly in my opinion).
1 tablespoon = 1/2 ounce (a tablespoon = 3 teaspoons)
1 teaspoon = 0.1667 ounces
So a gram is about a 1/2 a teaspoon. It is a very, very small measurement and may very well be the size of your little nibbles and tastes. If you're tasting a teaspoon consisting of half pancake and half syrup, it's probably about 15 calories, and about 10 are from fat, 5 are from sugar and 3 from carbs. Spark puts it at 15 calories and they are more accurate than I am.
