What is a 4-phase protein diet?
A 4-phase protein diet is a structured approach to weight loss that focuses on preserving muscle mass whilst the body burns fat. The four phases, Power Start, Combi, Transition and Lifestyle, guide you step by step from strict protein-rich eating towards a sustainable routine.
Why take a phased approach?
Crash diets often deliver quick results, but the weight tends to creep back on. A structured phase system helps stabilise weight loss gradually, making it easier to hold on to your new eating habits for good.
The four phases at a glance
- Phase 1 - Power Start: strictly protein-rich, low calorie. The kick-off period.
- Phase 2 - Combi: protein-rich products combined with one regular meal a day.
- Phase 3 - Transition: a gradual shift back towards normal eating.
- Phase 4 - Lifestyle: weaving protein-rich products into your everyday routine.
Who is this suited to?
The 4-phase system is designed for adults who want to lose weight in a structured, supported way. If you're uncertain, or have a medical history to consider, it's worth having a chat with your GP or a dietitian first.
