She will likely die before she reaches her goal (or shortly after). Ugh, this makes me sick

My thoughts exactly.  She's eating the wrong things to gain weight.  She's actually consuming things that will make her die.

Gaining weight is a matter of consuming more calories than you burn.  Consuming things that are unhealthy, such as foods high in sugar, cholesterol, or sodium are only going to contribute to an unhealthy end-result.  Diabetes, high-blood pressure, stroke, or heart attack.  Also, eating foods high in fat won't necessarily cause you to gain weight.  There is no metabolitic process in the human body to convert dietary fat (fat in food) into body fat.  The body either metabolizes the fat into glucose, which is used right away, or it expells it.

If she wanted to seriously gain lots of weight she'd eat excessive quantities of protien, such as chicken, fish, or other lean meats.  In addition, to possibly consuming protien powder.

Good post, but the bolded isn't exactly true. It's true that the body can't convert dietary fat into body fat directly but it does break it down to fatty acids which are then turned into fat. Otherwise, what would be the difference in eating lots of trans-fat vs. unsaturated fat?

The reason why both saturated and transfats are bad for you is because of their impact on cholesterol levels.  In terms of both, they effectively raise your bad cholesterol level.  However, transfats also reduce your good cholesterol level.  The higher the bad cholesterol level the more likely you are to have congestive heart failure or arterial diseases. 

You're correct in that fats are broken down into fatty acids, but they either become lipoproteins, like cholesterol, or chylomicrons.  Chylomicrons then transport the fatty acids to the cells where they are used for cell repair and energy via the Krebs cycle.  As long as your fat calories aren't in excess of the caloric use, then it won't be converted into body fat.  But the process to convert it into body fat requires that it be converted into glucose then be converted back into fat. 

There is no direct metabolic process to take dietary fat and it automatically becomes body fat.  Dietary fat is used first by the body for energy and other purposes before it ever adds to your body fat.  It's not a 1:1 thing.  If you eat a pint of ice cream, and that pint has 600 calories, and you're deficient 600 calories, it isn't going to turn into body fat.  Your body is going to use it.  If you've eaten 3,000 calories earlier that day and you've only burned 2500 calories, then yes, that 600 calories will add to your body fat, but not through a direct metabolic process.  The chylomicrons have to be broken down, and that process requires repeated reduction of the fatty acid into ATP before the ATP then is metabolized into glucose, and that glucose then goes through a reverse process to become fat that the adipose tissue can absorb.
