start weight 91.0 kg
morning #4 weight 89.2 kg
difference -1.8 kg
According to my scale, the percent fat has remained 23% (no decimal places). This got me thinking about the weight of fat this equates to.
First I assume that the best case is that 23% on my scale equated to 23.9%; and that this morning 23% equates to 23.0%. This would produce...
start % fat 23.9% x 91.0 = 21.7 kg
day # % fat 23.0% x 89.2 = 20.5 kg
difference -1.2 kg fat.
This is optimistic, so what 's the worst case, where 23% at the start equated to 23.0%; and 23% now equated to 23.9%...
start % fat 23.0% x 91.0 = 20.9 kg
day # % fat 23.9% x 89.2 = 21.3 kg
difference +0.4 kg fat.
Now if the proportion remained the same, where 23% equated to 23.5% both at the start and now, we have...
start % fat 23.5% x 91.0 = 21.4 kg
day # % fat 23.5% x 89.2 = 21.0 kg
difference -0.4 kg fat.
Hmmmm.
Let's say somewhere between 0.4kg and 1.2kg of fat lost. That's between 1 and 3 packs of butter!
The question is, how accurate is the fat measurement of the scale? There's always the question of skin resistance, hydration and so on.
