I love to eat raw veggies too. Snowpeas, cauliflower, tomatoes, peppers, cucumbers, celery, carrots, lettuce - at least half my diet is salads with little dressing.
As for the erotic side of carrots, I've met a few that looked interesting, but it turned out they were straight. Now Parsnips, definitely a queer vegetable. I got whistles and catcalls walking past a row of them at the grocer. I checked em' out but decided to turn them down, I acted all snooty and disinterested, but really the size was intimidating *blush*.
As for calorie counting - what an art. You'd think it was science and it could be but generally it's practice is an art. A calorie is a measure of heat given off when you burn something. NOTHING catchs fire in your body. So to get the accurate calorie content of a Big Mac you'd need to burn one in a calorimeter to get the maximum calories. Then eat one - on a completely empty digestive tract and empty bladder. Measure any urine generated by consumption of the Big Mac and burn it. Measure any fecal matter generated and burn it. Then subtract the urine and fecal caloric counts from the total for a Big Mac.
Food packagers do not express likely 'waste' calories for their food. So your 120 calorie snack has no indication on it saying only 80 calories is likely to be absorbed.
Comparied to a 100 calories snack where 90 is absorbed, its more attractive for dieters.
Also, mixing foods could change how they digest and the amount of calories absorbed by the body. Volume of food could be another variable. Speed of your intestines would matter.
Different people may digest foods completely differently. Both could eat a piece of pie with 450 calories and one absorbs 300 and the other 250.
I think it would be interesting to be involved in scientific research that studied food and calorie absorbtion. Maybe there are genetic classes of people who have specific digestive strengths and weaknesses. Being genotyped might help you determine the right diet.
If calorie counting works for you, great! I have trouble taking it too seriously when I know alot of the numbers are just guesswork.
