A Small Amount of Apple Vinegar Before Sleep Could Speed up Fat Loss

Even though there is no hard proof of this claim yet, there could be in near future. Some studies suggest that taking a few drops of apple vinegar before sleep could speed up fat loss and improve body composition over the long run. Not only fat loss, but some vinegar could give your muscles a wave of growth stimulus.

Apple cider vinegar and fat loss ?

Over the past years vinegar has been marketed as a weight-loss component in different supplements and there also is some scientific evidence about vinegar’s health benefits. Lately, however, research claims that a small amount of vinegar before your meals could slow down the spike of glucose levels.

Ordinary apple vinegar (that you use as a salad dressing) will have the same effect. As a result of this slow rise of blood glucose, the muscles will have a chance to burn the sugars longer before you start feeling hungry again.

It was first thought that the acidity of the vinegar slows down the digestion process, but a later study shows that it’s a bit more complicated than this.

In a study conducted at the Arizona State University, were giving two tablespoons of apple vinegar to type-2-diabetes patients (11 patients) before going to sleep. The Subjects’ sugar level was measured in the morning. The amount of glucose in the blood was lower by 4 percent (see fig 1), which is statistically significant.


apple vinegar effect on blood sugar


This result cannot be the effect from delaying the digestion of carbohydrates, according to the researchers, because the stomach is empty at night. So obviously there is a different process happening here.

An explanation of this phenomenon was given in an article published in Nutrition Research (Nutr Res. 2009 Dec;29(12):846-9.), backed up by the Kronos Longevity Research Institute.

The active ingredient in vinegar is acetic acid (structural formula shown on fig2). Acetic acid inhibits the enzyme phosphofructokinase-1 (PFK-1) in the muscles.


glucose to energy conversion

During the first step of the process of glycolysis (the process in which glucose in converted into energy). Fructose-6-phosphate and ATP are converted into fructose 1,6-biophosphate and ADP.

When that process is inhibited, the muscle cells burn more fat and store more glucose as glycogen in theory. A muscle cell with a lot of glycogen makes more energy available for growth processes.

We should mention that these studies were not conducted with weight loss as a final goal, but rather the researchers were interested in the effects of vinegar on blood sugar levels in diabetes patients.

You can experiment with apple vinegar by taking a table spoon before bed and before meals. Before going to bed take the vinegar with some high protein and low carb food, just to make sure you don’t upset your stomach.
