How to Choose the Best Meal Prep Meals for Weight Loss

If you’re short on time, pick a fully prepared service (Sam Spinelli, Trifecta, Factor, Freshly). If you like cooking but hate grocery runs, choose a kit (Green Chef). If you’re plant-based, Factor 75’s plant line provides macro-counted meals ready in 2 minutes. Always check the sodium—under 600 mg per entrée keeps water retention down.
