Valastro clarified that he was not advertising the program for a monetary gain. The chef also added that there is no one solution for all and that people should pick their own suitable weight loss regime.

However, he emphasized that the Optavia program was his chosen method and that he was thrilled about the results it had produced.

While the results of the Optavia program are visible on Valastro, professional nutritionists have a different take on the diet.

Expert dietician Jessica Cording told Yahoo Lifestyle that although the diet may be helpful for people who wish to lose weight quickly, they may gain back the weight after going off the diet.
