Vinegar and Weight Loss: Didn’t Work For Me

Mt. Fuji in Japan

Last November I started another self-experiment to see if vinegar consumption would lead to any weight loss in me.  I quit after nine weeks instead of sticking it out for the entire 12-week trial.  I just got tired of it and hadn’t seen any weight loss.  And I ran out of apple cider vinegar. 

Results?  No change in weight.

A Japanese study had shown loss of 2.2-4.4 lb in Japanese overweight study subjects.  Maybe it didn’t work for me because I wasn’t overweight.  Or because I’m not Japanese.  Or because I chose to do the experiment over the Christmas-New Years’ holiday, a notorious over-eating time of year. 

Oh, well.

Nevertheless, the vinegar option would be reasonable for an overweight person to try.

PS: I blogged recently about how vinegar diminishes blood sugar elevations after meals that contain complex carbohydrates.  So an overweight type 2 diabetic would be a perfect study subject.

Self-Experimentation: Does Vinegar Promote Weight Loss?

MPj03878520000[1]I reported recently that apple cider vinegar in a Japanese study population reduced body weight by 2.2 to 4.4 pounds (1—2 kg) over 12 weeks.  The dose was 15—30 ml daily, or 1—2 tbsp.  The researchers think the active ingredient is simply acetic acid.

On November 14, 2009, I started another self-experiment: I’m drinking 7.5 ml (1.5 tsp) Heinz apple cider vinegar twice daily, mixing it in 8—10 fl oz of water plus 1/2 packet (1.75 g) of  Truvia sweetener, with or without 1 heaping tsp of sugar-free Metamucil.  I’ll do this for 12 weeks.  If I weighed over 200 lb, I would have chosen the 30 ml/day vinegar dose.  But I’m only 155 lb.

Why Truvia?  We had some in the house, I don’t think I absorb its erythritol and rebiana, and it makes the vinegar much more palatable. 

Why Metamucil?  You can figure that one out, Spanky.

A small-scale “experiment of one” like this isn’t worth much.  Too many variables can affect the outcome.  For instance, the holiday season is just around the corner.  Most Americans gain five pounds between Thanksgiving and New Years.  I’ve been no exception to that in the past. 

I’m not totally committed to the experiment.  But I’ve gotta do something with that huge bottle of vinegar my wife bought.

Drink Vinegar and Lose 2-4 Pounds Effortlessly

CB052540Japanese researchers recently documented that daily vinegar reduces body weight, fat mass, and triglycerides in overweight Japanese adults. 

Beverages containing vinegar are commonly consumed in Japan.  The main component—4 to 8%— of vinegar is acetic acid.  Vinegar can lower cholesterol levels, lower blood pressure, and limit increases in blood sugar after meals. 

Japanese researchers studied the effects of vinegar on 175 overweight—body mass index between 25 and 30—subjects aged 25 to 60.  Men totaled 111; women 64.  Average weight 74.4 kg (164 pounds).  They were divided into three groups that received either a placebo drink, 15 ml apple vinegar (750 mg of acetic acid), or 30 ml apple vinegar (1,500 mg acetic acid).  Placebo and vinegar were mixed into 500 ml of a beverage, half of which was drunk twice daily after breakfast and supper for 12 weeks.  Changes in body fat were measured with CT technology.  Subjects were told to eat  and exercise as usual.   

Results

By the end of the 12 weeks, weight had decreased by 1-2 kg (2.2 to 4.4 pounds) in the vinegar drinkers, with 30 ml of vinegar a bit more effective.  CT scanning showed that the lost weight was fat mass rather than muscle or water.  Triglyceride levels in the vinegar groups fell by about 20%.  The placebo drinkers saw no changes. 

Four weeks after the intervention ended, subjects were retested: values had returned to their baseline, pre-study levels. 

The scientists report that the acetic acid in vinegar inhibits production of fat and may stimulate burning of fat as fuel.  Although vinegar contains many other ingredients, they think the acetic acid is responsible for the observed changes.

My Comments

It’s possible that apple vinegar components other than acetic acid led to the weight loss and lowered triglyceride levels.  Further study could clarify this.

These results may or may not be applicable to non-Japanese races.

This study supports the use of vinaigrette as a salad or vegetable dressing in people trying to lose weight with diets such as the Ketogenic Mediterranean Diet.  Vinaigrettes are combinations of olive oil and vinegar, often with various spices added.  If you eat a salad twice a day, it would be easy to add 15 ml (1 tbsp) of vinegar to your diet daily. 

With a little imagination, you could come up with other ways to add 15–30 ml (1–2 tbsp) of vinegar to your diet.
