Will I gain weight drinking coke and having lots of cheese?
Maybe,
But it really all depends on how many calories your body actually digests and absorbs, as opposed to many calories it expends. ,
Many people with digestive issues do not digest all their food, and the calories pass right through them, instead of getting into their blood system.
if you eat 3,000 calories, but your body only digests and absorbs 500 of them, you'll still end up losing weight rather than gaining.
Going on a nice healthy diet usually results in losing weight, which is usually the goal -- for those without digestive issues.
but being too thin can be just as dangerous to your health as obesity, and consuming massive quantities of junk food usually does help pack on the pounds. In the short term, may very well do your body more good than harm, so no, don't think you've lost your mind.
Cheese is often difficult to digest, but helps bind you up (i.e., result in constipation.). While coke is pure sugar, and absorbed almost directly into the blood stream.
There are medical conditions, such as epilepsy, which are being successfully treated by consuming massive quantities of saturated fat, entire meals consisting of butter and bacon, and drinking pure canola oil. Doesn't seem possible? Here's a link to an article from Fox News:

So might I suggest some fries and potato chips? Just to round out your new temporary diet plan?
