Prolon UK is a company that offers a five-day plant-based restricted-calorie meal program designed to imitate metabolic changes that can occur from fasting for a short time. It's intended to "reset your metabolism by helping your body improve its response to insulin, which is essential for optimal health and plays a role in weight loss". The entirety of what you'll eat during this time is sent to you in five boxes—one for each day of the diet—which contain various energy bars, soups, drinks, supplements and snacks. Users follow the diet’s regime for one week out of the month before returning to their normal diet, but the best benefits are seen after three consecutive months, the company notes.
On the review side, Prolon has received a 4.0 rating from over 2,500 reviews on one platform, with 61% of reviewers giving it a 5-star rating. Customers have praised the products and reported feeling better, more alert, and focused after using them. However, there were also some negative reviews, with 15% of reviewers giving it a 1-star rating. Some customers reported issues with promised discount codes not being delivered.
Please note that while many users have found success with Prolon, individual results may vary, and it's always recommended to consult with a healthcare provider before starting any new diet or nutrition program.
