It is not necessary to log your weight every day, but the more information you give to Coach Alice, the better her recommendations will be on your progress, especially since your weight can fluctuate so much from day to day.
However, if you feel that daily weigh-ins are too much or it’s not feasible for you right now, then at a minimum, you should weigh yourself 4 times per week. This will be the information Coach Alice requires to then make any alterations to your nutrition depending on your progress.
