Why Alcohol Makes you Fat and stops you from Losing it

So you want to lose weight and want to know whether or not you should drink alcohol on a weight loss programme.  The sad fact of the matter is that alcohol makes you fat and stops you from losing it too.

Alcohol has a two-fold negative effect on our ability to lose fat

  1. Alcohol is highly calorific and easily over-consumed. Compare its calorific value with the other components of our diet:
    Alcohol is 7kcal/g, fat is 9 kcal/g, both protein and carbohydrate are roughly 4kcal/g).
  2. The simple presence of alcohol in your system has a hugely negative impact on your ability to metabolise fat.

 

The conclusions that alcohol makes you fat was illustrated by a study where 8 men were given two drinks of vodka and lemonade separated by 30 minutes.

Each drink contained just under 90 calories. Fat metabolism was measured before and after consumption of the drink.

FOR SEVERAL HOURS AFTER DRINKING THE VODKA, WHOLE BODY LIPID OXIDATION (a measure of how much fat your body is burning) DROPPED BY 73%!  So that means that the men burned fat less efficiently after drinking the alcohol.

The reason why alcohol has this dramatic effect on fat metabolism has to do with the way alcohol is handled in the body.

Rather than getting stored as fat, the main fate of alcohol is conversion into acetate, and the presence of acetate in the system puts the brakes on fat loss. The greater the quantity of alcohol, the greater the quantity of acetate created, the less likely fat is metabolised.

In other words, your body tends to use whatever you feed it, and after a time becomes adapted to the macro nutrient intake.

Unfortunately when acetate levels rise, your body burns the acetate preferentially.  So the body simply burns the acetate first, this basically pushes fat oxidation out of the metabolic equation.

So the conclusion is that if you are attempting to lose weight, excessive alcohol consumption will hamper your weight loss efforts, and so it should be avoided, or at least cut down considerably. And that’s not mentioning the fact that when you drink alcohol you may be more inclined to eat excessively and exercise less…. when consumed inexcess, it’s easy to see why alcohol makes you fat.
