The invention provides a kit comprising a satiety inducing component A, useful for the treatment and/or prevention of obesity and a component B complementing component A. Component A comprises a first ingestible solid formulation of a lipid material and a water-swellable or water-soluble polymer, said first ingestible solid formulation being provided in form of ingestible particles that may be used as a partial or full meal replacement. Component B complements component A in that it provides e.g. specific nutrients such as unsaturated fatty acids, vitamins, proteins, amino acids, micro- nutrients, dietary elements, dietary fibres or combinations thereof to a human subject in order to reduce the risk of any deficiencies thereof during a dieting schedule. These nutrients in component B may be provided in an oil, a granulate and/or a powder or powder blend. Alternatively, component B may comprise a second ingestible solid formulation similar to the first ingestible solid formulation, which may be provided in form of ingestible particles, but also in other forms than component A, e.g. as snack-bars.
