Body composition analysis

I am planning on having my body fat % tested by skin fold method and was wondering if there was an optimal time of day to have it done. For example is it not a good idea to go in the morning because of dehydration? Thanks

I do not think it is important when and how you will test your bf% on this particular occasion, but it is important that next and every other time you do it under the same circumstances. This also applies to measuring body weight. I can easily fluctuate ± 4 kg during the day because of water retention and food content in my stomach. That is why I always measure my bodyweight Sunday mornings after I go to the toilette and after a fibrous meal I eat in the evening.
