Could Seaweed Help You Lose Weight?
Diabetes, Obesity and Metabolism

A little of the “green stuff” before dinner could help you drop a few pounds.

In a new study, researchers recruited 76 overweight volunteers who ate 400 fewer calories than they burned per day. In addition, half of them ate a pre-dinner “appetizer” of 180g of agar-agar, a flavorless compound made from seaweed.

At the end of 12 weeks, those test subjects who ate the agar-agar lost nearly 4 1/2 percent of their body weight and were inclined to eat a dinner consisting of 300 calories, on average. Those who didn’t eat the agar-agar lost only 2 percent of their body weight, and their dinner was more than double in size—more than 600 calories.

The researchers speculate that the agar-agar helps people lose weight because it has no calories and, as it’s basically a fiber, it swells in the stomach, causing a feeling of fullness, which makes you eat less.

Nutrition experts say many fruits or vegetables, when eaten before a meal, can do the same thing, and those who eat more of these have a better time maintaining a weight loss.

Here’s the agar-agar recipe: Combine a quarter cup of seaweed with two cups of apple juice and two cups of water. Heat it until the seaweed is dissolved, then pour it into a flat pan and refrigerate it until it gels, which usually takes about an hour. Eat half a cup of this mixture half an hour before dinner.
