Should I restrict calories or "prepare my body" before starting ProLon®?

You don't need to make any long-term, major lifestyle changes before starting the program, which is one of the reasons why it's so popular. Published clinical trials did not include any specific preparatory routines prior to participants starting ProLon. However, to help with your transition, in the days leading up to using ProLon, we suggest you

be mindful of your portions and avoid overeating, eat nutritious foods, increase your intake of plant-based foods and of vegetables, avoid processed and sugary foods, and cut down on your caffeine as much as possible.
