Deficit / Cut Planner
Roughly estimate how long it may take to reach your target weight.
Why is it only rough?
Weight loss is not linear. Water, digestion, sodium, carbohydrates, NEAT, training and adaptations can change the visible trend.
What is a good deficit?
For many people, a moderate deficit is more sustainable than an aggressive cut.
