Convert 8 Beers/Night to Weight Gain in Pounds

AI Thread Summary
To determine weight gain from consuming 8 beers per night for five nights, which totals 6098.4 kcal, one must consider both energy expenditure and individual metabolism. The conversion of kcal to pounds requires precise data on daily caloric needs and assumes all excess calories are converted to fat, which is unrealistic. Simplifying the calculation by using fat or carbohydrate caloric values can provide a rough estimate, but this overlooks water retention and additional food intake post-consumption. The discussion highlights the complexity of accurately predicting weight gain from caloric intake alone. Overall, the problem lacks sufficient detail for an exact answer.

HELP! pounds to kcal

i need help figuring out this problem, I am sure its simple but just has completely slipped my mind.

8beers per night for five nights(have all reference tables and figured 6098.4kcal consumed). how many pounds will the person gain? can't figure it out

You are trying to add apples and oranges.
Kcal is a unit of energy, while pound is a unit of mass.
For determining how much weight in the long run a person will gain after consuming X kcal you would need precise data on his energy consumption.
 


You will need to assume two things - first, beers gave kcal above the daily requirement for the person, second, it was all converted to fat. Neither assumption is true, but it can give some ballpark.
 


As both posters noted, the problem is incompletely stated. One simplification is simply to convert the caloric value (6098.4 kcal) into an equivalent weight by using either fat (9 kcal/g) or carbohydrate (5 kcal/g, IIRC). That neglects the weight of the water content, and I have no idea how much of that water is retained.

It also neglects the effect of post-binge snacking... :)
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
