AggressiveCut is a fitness tool. It is not medical advice. The aggressive calorie deficits this app prescribes are prescribed by design — as fitness programming for non-medical use — and are not appropriate for every person.

Do not use AggressiveCut if any of the following apply:

  • You are under 18.
  • You are pregnant or breastfeeding.
  • You have a history of an eating disorder.
  • You have kidney or liver disease.
  • You have type-1 diabetes.
  • You are undergoing active cancer treatment.
  • You take medications that affect metabolism, appetite, or body composition.

Stop using AggressiveCut and consult a physician immediately if you experience:

  • Dizziness or fainting.
  • Menstrual changes or loss.
  • Unusual hunger that doesn’t resolve with adherence.
  • Significant mood changes, depressive symptoms, or obsessive thoughts about food.

AggressiveCut enforces safety floors during onboarding: a minimum starting BMI of 18.5, a minimum starting body-fat of 10% for men and 18% for women, and a 1,200 kcal minimum calorie floor during the cut. If your stats fall below these floors, AggressiveCut will not let you start a cut.

These floors do not substitute for medical judgment. They are a minimum, not a sufficient, safeguard. If you have any health condition or concern, consult a physician before using AggressiveCut.

Research behind the safety floors

The protocol and safety floors referenced above draw on peer-reviewed evidence on muscle preservation during aggressive calorie deficits. The bibliography below is a shortlist; the full review lives in the product’s internal research file.
