FitPlus for Women
Women’s bodies are biologically designed to store more fat than men. This isn’t just about weight—it’s a natural function to support reproductive health and overall well-being.
✔ Why Do Women Have More Body Fat?
Women have more fat-storing enzymes and fewer fat-burning enzymes compared to men. Additionally, the hormone oestrogen encourages fat storage, especially around the hips and abdomen, to protect both the mother and a potential baby.
✔ Hydration & Body Fat Readings
Women experience greater fluctuations in hydration levels due to their menstrual cycle. This can cause temporary changes in body fat readings, as fluid retention can make weight fluctuate day to day. Tracking your body fat percentage over a full month can help identify patterns and establish a reliable baseline.
✔ Menopause & Body Composition
As hormonal levels shift during menopause, changes in water retention, fat distribution, and metabolism may impact body composition readings. Monitoring trends over time can provide a clearer picture of overall health.

Pregnancy & Body Composition Analysis
Is it safe to use a body composition monitor during pregnancy? Yes! There are no known health risks in using Tanita’s BIA technology while pregnant.
However, pregnancy causes significant hormonal changes, leading to higher fat storage around the abdomen and hips to support fetal development. This means body fat readings may not be as evenly distributed or comparable to pre-pregnancy levels. Additionally, due to limited research, specific “healthy” body fat ranges for pregnant women are not yet validated.
Balancing Body Fat: Why It Matters
✔ Too Little Body Fat?
Having very low body fat can lead to hormonal imbalances, anemia, and an increased risk of osteoporosis later in life. Young women may also experience irregular or missed periods (amenorrhea), which could affect fertility.
✔ Too Much Body Fat?
On the other hand, excess body fat has been linked to serious health concerns, including:
🔹 Increased risk of breast cancer after menopause (especially in women on hormone replacement therapy)
🔹 Higher chances of endometrial cancer
🔹 Obstetric and gynecological complications
🔹 Higher risks of stress incontinence, infertility, and metabolic disorders
Maintaining a healthy body fat percentage is key to overall well-being, hormonal balance, and long-term health.
