Why do some people gain weight from drinking?
According to Elizabeth Somer, R.D., a nutritionist and author of The Origin Diet (Henry Holt, 2001) "The reason you gain weight from alcohol is that you don't compensate by eating less later. You still eat the same amount, regardless of whether you had the drink." A 1.5-ounce shot of any 80-proof liquor vodka, rum, tequila, gin etc has about 96 calories. A straight shot of 100 proof has about 124 calories. (The proof number is twice the alcohol content of the beverage so 80 proof means the liquor is 40 % alcohol 100 proof is 50 %.) Proceeding is why so many experts say if you are going drink alcohol use sugar free and low calorie mixers as to add fewer empty calories to your diet.
