I'm assuming salted peanuts is your average peanut since technically both types can be salted. The difference between "salted peanuts" and cocktail peanuts is that Virginia peanuts are often called "cocktail nuts" and are considered large-kernelled while I'm guessing that the average peanut is smaller. I might be confused but I hope this helps somewhat.
If you eat less when you are in weight training, you will loose weight because you burn more calories in training then not. If you're calorie intake remains the same, you will burn more and lose more body fat.
Even having a cold or sore throat makes you more susceptible to dehydration because you're less likely to feel like eating or drinking when you're sick. So yes you can get dehydrated in the cold.
