Being "chubby" isn't a medical term, but it generally describes being in the Overweight BMI category, starting at a Body Mass Index (BMI) of 25.0 to 29.9, where you have extra body fat, but aren't yet in the obese range (BMI 30+). This translates to specific weight ranges that depend on your height, for example, a 5'4" person is overweight around 145-169 lbs, while a 5'10" person is overweight from 174-202 lbs, according to American Cancer Society BMI data.
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to < 25.0, it falls within the “healthy” weight range. If your BMI is 25.0 to < 30.0, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obesity range.
"Chubby" isn't a medical term, but it generally refers to being in the Overweight BMI category (25.0 - 29.9 kg/m²) or starting to enter the Obese range (30+ kg/m²), though BMI doesn't account for muscle, body fat percentage, or body composition, making it a general guideline for adults. To find your weight in kg, calculate your BMI: Weight (kg) / Height (m)², and use the ranges (Healthy: 18.5-24.9; Overweight: 25-29.9; Obese: 30+) to see where you stand.

Whether 80 kg is overweight for a woman depends entirely on her height, as weight is relative to body size; using Body Mass Index (BMI) or height charts shows that for shorter women (e.g., under 160cm/5'3"), 80kg is likely obese, while for taller women (e.g., over 175cm/5'9"), it might fall within the healthy to overweight range, but always use a calculator for accuracy as BMI doesn't account for muscle.

Your most consistent and "true" weight is generally in the morning, after using the bathroom and before eating or drinking anything. This provides the most accurate baseline because your body has processed the previous day's food and fluids overnight, resulting in less fluctuation from digestion, water intake, and daily activities. Weighing at the same time, in the same minimal clothing, and under consistent conditions (like in the morning) helps track trends better than weighing at night or randomly.
