I there a difference between a 1000 cals of crap and 1000 cals of greens?
Which weighs more: a lb of feathers or a lb of lead? Its an old question, and the answer is they weigh the same. I have always believed that wt loss is based on calorie deficit. If you burn more than you take in, you lose wt. (Not everyone will lose the same amount if they eat the same and do the exact same activities though, because not everyone burns calories at the same rate.)
No where in that formula is there a place for whether the food you consumed was high in fat, sugar, or carbs. So based on the formula, does it matter if you eat 1400cals of leafy vegetables or 1400cals of grapes? Note that I said calories worth. For that matter, I could compare 1400cals of vegetables and 1400cals of candy bars. In the formula, it should not make a difference. Its just that you would only get 4-5 candy bars vs a very large pile of lettuce.
I'm not asking about the nutricious comparison. I am only interested in the affect on wt loss. I realize the body process foods differently, but is the formula correct or not? If it is correct, then you would have to say it doesn't matter where the cals came from, be it crap or vegys.
Any input would be appreciated.
I'm going to post a thread on the lounge to discuss the relationship between sugar, calories, carbs, and wt gain. I've never understood why some believe a 2cal grape (high in sugar) or a 2cal babby carrrot (high in carbs) has much affect on wt. I've always felt that its like asking which weighs more, a lb of feathers or a lb of lead. The only formula for wt gain I know of is calories in - calories burned. Nothing in there about where the calories come from. For instance, if I eat 1000cals of crap or 1000cals of greens, its 1000cals from either category (I just get a huge quantity of greens and a small quantity of crap). Its something I've never understood and would like some input on

From Rose Bloom (posted on team PNP2013):
"@peelout there was a belief for many years that weight loss was determined by a simple equation of calories in minus calories out and also that all calories are equal. However, this belief is no longer widely accepted.
Here is an article by Robert Lustig:
ROSEBLOOM: Thanks for the feedback, which I read. Important things I learned:
1. You don't absorb as many of the calories from high fiber foods as the food has. EX: Almonds have 160cals (no quantity shown) but you only absorb 130cals.
2. It takes more cals to metabolize protein that carbs. (Thermic affect).
3. The article did not do a very good job at discussing sugar. It neither discussed the absorbtion rate of sugar, nor the metabolizing rate. All it said was it increased obesity but did not support why. It showed a correlation between sugar intake and obesity, but did not discuss the why.
Remember, I am only interested in the effect on wt gain, not nutricion. So points 1 and 2 would give a reason why some foods give less wt gain. However, the calorie deficit formula still works, but the calorie amount of foods needs to be changed (based on 1 and 2). So I wonder if there is a calorie counter that adjusts for 1 and 2. For instance, an adjusted calorie counter would not show just the available calories, but would show the absorbed caloiries. The number of potential calories is a useless number. The number of calories the body actually absorbs minus the number of calories it takes to digest the food would be a much more useful number. Has anyone ever seen a calorie chart that gives this much more useful number? Lynetta, could you ask your instructors if they have ever seen such a chart if you don't already know of its existance?
Great info. Hope to hear more.
