So, Bob can stand to lose about 10 pounds. Using the
recommendations above, he could take 10 weeks to lose this weight
in fat. If all the weight lost was fat, his body fat percentage should
decrease to 15%.
Women
Sue's body fat was 23%, and her total body weight was 145 pounds.
• TBF 33.35 = 145 x 23/100
• FFBW 112 = 145 – 33
• IF (for 18% bodyfat) .82 = (100 – 18)/100
• IBW 136.6 = 112/.82
• Pounds to lose = 8.4
If Sue took 8-9 weeks to lose this weight in fat using the
recommendations above, then her body fat percentage will decrease
to about 18%.
Gaining, losing or maintaining body weight is little more than a
matter of arithmetic. If more calories are consumed than expended,
weight is gained. If more calories are expended than consumed,
weight is lost. If calories expended and consumed are equal, weight
will not change.
