A low calorie, low fat food product of a foodstuff and a stable foam. The foam has a liquid matrix, gas bubbles and a structuring agent that forms a lamellar or vesicle cage structure without generating a gel imparting a rubbery texture. The lamellar / vesicular cage structure entraps a substantial portion of the bubbles and liquid matrix therein in a sufficiently compact structure that substantially prevents drainage of the liquid matrix and coalescence and creaming of the bubbles to maintain stability of the foam even when the foam is subjected to heat shock. The food product contains less than 0.5 grams of fat, and provides a caloric density of less than 200 kcal per each 100 ml serving of gas bubble-free liquid matrix.
