Reasons for changes in body fat scale data

Increasing weight and body fat: This indicates excessive total calorie intake, possibly from excessive consumption of fat or staple foods.
Increasing weight, decreasing body fat and body fat percentage: This indicates that some fat has converted into muscle, which is denser than fat, leading to weight gain. This is a desirable result, proving that the body fat scale is working and helping you achieve a leaner physique.
No data has changed, but your basal metabolic rate has decreased: This may be related to insufficient exercise. Skipping breakfast or insufficient protein intake can also cause this.
Decreasing weight, muscle mass, and basal metabolic rate, while increasing body fat percentage: This indicates that you are dieting. Although you are losing weight, you are losing water, not fat.
