What the Reverse Diet Calculator calculates
Calculate the endpoint and cumulative arithmetic of a user-selected stepped calorie plan.
The calculator organizes a plan but does not recommend an increment or promise a metabolic effect.
How to use the Reverse Diet Calculator
- Enter starting daily calories.
- Enter the planned weekly increase.
- Choose how many increases are applied.
- Review the endpoint separately from expected outcomes.
Continue with the TDEE Calculator. Keep whole-day energy needs separate.
Formula, variables and calculation order
final = start + increment x weeks; cumulative added calories sum the daily weekly steps from 1 through N.
Inputs are validated and normalized before calculation. Full precision is retained until the displayed result is rounded.
Cross-check a different part of the decision with the Macro Calculator. Translate an energy target into macronutrients.
Worked example and boundary check
Worked example
Starting at 1,800 kcal and adding 75 kcal for six weekly steps ends at 2,250 kcal/day.
Boundary check
Changing intake does not guarantee a matching change in measured expenditure or body weight.
How to interpret the result
Use the output to document a chosen schedule. Nutrition and eating-disorder care requires appropriate individual guidance.
- Does not recommend a calorie target or increment.
- Does not model expenditure adaptation, adherence, or weight change.
- The cumulative total assumes each weekly step is held for seven days.

Inputs, outputs and result meaning
Shows auditable endpoint and cumulative arithmetic while refusing unsupported metabolic promises.
Inputs
- Starting daily calories
- Use the current planned daily energy target. Supported units are kilocalories (kcal).
- Planned weekly increment
- Enter the user-selected step; the calculator does not recommend it. Supported units are kilocalories (kcal).
- Number of weekly increases
- Count the increases applied. Supported units are count.
Outputs
- Planned final daily calories
- This is the primary result. It is displayed in kcal/day. The display rule uses up to 0 decimal places.
- Total daily increase by final week
- It is displayed in kcal/day. The display rule uses up to 0 decimal places.
- Cumulative added calories across stepped weeks
- It is displayed in kcal. The display rule uses up to 0 decimal places.
- Weekly increases
- It is displayed in weeks. The display rule uses up to 0 decimal places.
Final daily calories = starting calories + weekly increment x increases. Keep the result label, unit, selected mode, and stated limitations together when sharing the answer.
Frequently asked questions
Does reverse dieting boost metabolism?
The calculator makes no such promise.
What increment should I use?
That is deliberately not prescribed here.
Why show cumulative added calories?
It makes the stepped arithmetic auditable.
Can I use zero increment?
Yes for comparison, though the endpoint will not change.
