When To Calculate Weight Loss Rate
A Jim teacher stands by a whiteboard. She points and says, “You are 90 kg. You want 75 kg in 15 weeks. You ask how fast to lose weight.” You listen. You need a plan. You calculate to avoid too fast loss. You check progress weekly. You adjust as you go.
Example With Steps
First, know the formula: Rate (kg/week) = (Current weight − Target weight) ÷ Weeks.
Second, plug values: (90 − 75) ÷ 15 = 15 ÷ 15 = 1 kg/week.
Third, convert to calories: 1 kg ≈ 7,700 kcal.
Fourth, daily deficit = 7,700 ÷ 7 ≈ 1,100 kcal/day.
Finally, decide mix of food and activity to hit ~1,100 kcal/day deficit.
Pro Tip:
You can do a quick manual divide to get weekly loss. Yet a calculator speeds math and keeps safety in mind. Ultimately.
