Optifast by Nestlé Health Science is a scientifically formulated weight management solution used as a meal replacement diet. It contains a balanced mix of proteins, fibre, carbohydrates, and essential micronutrients.

Each serving delivers fewer calories than a regular meal (up to ~60% less) while still providing satiety and nutrition, making it suitable for structured weight loss programs.

Its low glycaemic index (GI) and fibre blend (PHGG) help manage hunger, improve digestion, and maintain steady energy levels.
