This question came up in another thread and I thought it would be interesting to explore.
If any of you follow Tom Venuto (see book list on this forum) then you have heard the case for weekly body fat measurements. Others may do this too but it is basically a mandatory thing on a BFFM diet and that is how I ran into the idea.
So here's how it's done:
1) This is only for use on a "normal" diet. No diet that drastically changes water weight or glycogen should be going on when doing this. It's okay if these things change drastically the first week but if it's on a continual basis then this method will not be a useful tool.
2) You are not looking to find your exact body fat %. You are only interested in the amount of change in your body fat % over time. So don't over concern yourself with the number, look at the change over time.
3) Get measured by the same person each week. This encourages consistency in measurements. And this is a big one too because different people can give very different measurements.
4) Measure at the same time on the same day each week. This is because things fluctuate slightly during the day and after different activities so doing it at the same time will further encourage consistency.
5) It helps if on the day you pick to do measurements, you have roughly the same level of activity, eating schedule, etc. each week. This promotes even more consistency.
6) Do not over-interpret the data. You should be looking at trends not week to week changes. If something is off for two or three weeks then you might adjust your diet accordingly but if something is off for just a week then you shouldn't jump to conclusions.
So that's how weekly body fat measurements are generally done at least in the Venuto circle. It can be very useful for recognizing when something goes wrong and diagnosing why and what to do about it. So to me, it's worth it. The more data I have at hand, the better decisions I can make about diet and training.
