Do you recommend any supplements during the program? If yes then what are those?

Yes, along with the diet you need to continue vitamin D, E, and vitamin B12 supplements. Also, add multi-mineral supplements and Omega 3 fatty acids. These supplements are not given for weight loss, rather it restore the lost minerals and vitamins due to inappropriate intake of diet. Most of the multivitamins are loaded with minerals. So please add
1.) Capsule A to Z Gold once a day for 1 month.
2.) Solution Arachitol Nano 60k (5ml) once a week for 8 weeks.
3.) Capsule Omega 3 or HHOMEGA once daily at bedtime for 3 months.
Supplements work well if you take them after the meal.
