FitLine vs Metaflow: A Direct Comparison of Two Meal-Replacement Shakes
Overview: Two Different Concepts
FitLine and Metaflow follow two different approaches to meal replacement. A direct comparison helps you decide which concept fits your goal.
FitLine (PM-International AG) offers ProShape All-in-1 from its Weight Management line — the direct counterpart to Metaflow, since both products follow the same core principle: replacing individual meals to create a calorie deficit. ProShape costs €35.90 per canister (13 servings), while Metaflow starts at around €99.90 for the starter set.
Metaflow (Nexum Production) is a classic meal-replacement shake: it replaces individual meals to create a calorie deficit, and is specifically designed for weight loss.
