計算式

Pounds to gain = goal weight − current weight. Days needed = (lb to gain × 3500) ÷ daily calorie surplus, using the standard 3,500 kcal ≈ 1 lb approximation.

ステップごとの説明

  1. Enter the Current weight (lb).
  2. Enter the Goal weight (lb).
  3. Enter the Daily calorie surplus.
  4. Click Calculate to see your result instantly.

実例

Example: With Current weight (lb) = 140, Goal weight (lb) = 160, Daily calorie surplus = 500, the Weight Gain Calculator gives Lb To Gain: 20, Days Needed: 140.

How accurate is the Weight Gain Calculator?
The Weight Gain Calculator applies the formula exactly as calculated — Pounds to gain = goal weight − current weight. Days needed = (lb to gain × 3500) ÷ daily calorie surplus, using the standard 3,500 kcal ≈ 1 lb approximation. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is this a medical diagnosis?
No. The Weight Gain Calculator provides an estimate based on standard formulas and general population data, not a medical diagnosis or personalized clinical advice. Individual results can vary — consult a doctor or other qualified healthcare provider for medical concerns.
