Can I replace the L-Bar with a Fast Bar or other types of nuts?

Due to the carefully studied and strategically formulated macro- and micronutrient ratio in the L-Bar, there is no substitute that meets its exact profile. Although Fast Bar is very similar to Prolon’s Nut L-Bars, there is a slight difference in size, calorie count, and sugar content. Any substitute will likely differ from the ratio and amount of specific macro- and/or micronutrients and may interfere with the benefits of the diet. If you elect to simply omit the L-Bar, please note that changes in the food included in the program, including the removal of foods, have not been studied. Any changes may interfere with both the safety and the outcome of the diet.
