I doubt excluding sugars from your diet made a difference, or excluding alcohol alone did it. Beer in general do not have that many calories, it is usually junk food accompanied beer is what adding a lot of calories and fat.

^^^ IMHO, since there is a chance you were consuming pound of sugar and six-pack of beer daily :)

Beer usually hovers around the 150-200 calorie mark per bottle. If you're putting away a six-pack every weekend, that adds up very quickly.

(Which is not to say that you'll magically lose weight if you stop drinking, or that it's impossible to lose weight if you're drinking every week.)

If you drink 6 pack in one evening - this is "overeating" already. All these extra calories will immediately start converting into fat.

On the other hand if you drink 6 pack during the span of the whole week - it will hardly make a difference.

So yeah - it really depends on how much beer peak usage we are talking about here.
