|Spicy Carrot Soup (recipe) - Would it be more satiating, if it was made with MSG? The study at hand shows: Yes, if it's eaten as an entree, it will actually reduce your food intake more than an MSG-free soup, you'd eat before a meal.|
In their latest experiment, Una Masic and Martin R. Yeomans from the University of Sussex wanted to elucidate, whether one could make use of the satiety effect without increasing the risk of overeating.
Suez In the corresponding trial, which involved a total of thirty-six low-restraint (not dieting or thinking "Oh my god, I am gonna be fat, when I eat this!") males (mean age: 21 years; BMI: 22 kg/m²).
On all test days, the subjects received identical breakfasts [80 g cereal (Crunchy Nut Cornflakes; Kellogg’s), 200 g semi-skimmed milk (Sainsbury’s plc) and 200 g orange juice (Sainsbury’s plc) (total 2107 kJ (503·6 kcal))] before they consumed a MSG or no-MSG carrot and spice soup as an entree for lunch.

Unlike the ADHD connection, the headaches and other symptoms some people suffer from, when they ingest large amounts of MSG are non-debatable, though. For me, personally, the existence of these effects is reason enough, not to use MSG deliberately as a supplement. It's yet not enough to run away, when I occasionally realize a food item I am about to eat contains some mono-sodium glutamate.

Moreover, a larger preload produced a more significant reduction in energy intake on the subsequent main dish (Pasta) and dessert (Ice cream), than a small one. And last but not least, there was a significant advantage for the balanced, higher protein, lower carbohydrate version of the soup that had been spiked not just with MSG, but also with whey (in both the active and control trial; see Figure 1, right bars).
