What these numbers come to

Body mass index: 29.4 Overweight
Waist to hip: 0.84 below 0.85
Waist to height: 0.57 Increased central adiposity

Bust 102.7, waist 96.1, hips 115.1 cm. Shape by these numbers: triangle.

A BMI of 18.5 to 24.9 at this height is 53.5 kg to 72 kg.

The figure is an estimate drawn from a general body model. Two people with the same numbers can carry their weight differently, so treat it as a likeness, not a scan.

The 3D body visualizer weight loss view draws 2 figures of one height: a current weight and a goal weight. The view opens on a female figure 170 cm (5 ft 7 in) tall at 85 kg (187 lb), with a goal of 72 kg (159 lb). The goal is a light outline over the current figure, and a table lists the change in each number.

How the 3D body visualizer weight loss view works

The 3D body visualizer weight loss view works by fitting the same model at 2 weights. Now is the solid figure. Goal is the outline. The Side by side button stands the 2 figures next to each other.

Each figure is sized to its own weight. The tool divides the weight by a body density and gives the figure that volume, then reads the bust, waist and hips off the figure the way a tape would.

At 170 cm, 13 kg less takes the model's waist estimate from 96.1 cm to 83.0 cm.
Number	Now	Goal	Change
Weight	85 kg (187 lb)	72 kg (159 lb)	−13 kg (−28.7 lb)
BMI	29.4	24.9	−4.5
Bust	102.7 cm	94.9 cm	−7.8 cm
Waist	96.1 cm	83.0 cm	−13.1 cm
Hips	115.1 cm	106.3 cm	−8.8 cm
Waist to height	0.57	0.49	−0.08

A BMI of 29.4 is in the CDC's overweight category, and 24.9 is in the healthy weight category. NICE classes a waist to height ratio of 0.5 to 0.59 as increased central adiposity and 0.4 to 0.49 as healthy central adiposity.

The 2 figures are the model's typical bodies at 2 weights. The figures do not predict how one person's body will change, and two people with the same numbers can carry their weight differently. For your own health, a doctor or nurse can assess you in person.

3D body visualizer weight loss formula

The 3D body visualizer weight loss view uses 2 formulas for the change between the figures.

At 170 cm, a change of 13 kg is 4.5 BMI points and 15.3 percent of 85 kg.
Formula	For the opening figures
Change in BMI = weight change in kg ÷ height in m, squared	13 ÷ (1.70 × 1.70) = 4.5
Share of body weight = weight change ÷ current weight	13 ÷ 85 = 15.3 percent

The change in BMI depends on height. The same 13 kg is 4.5 BMI points at 170 cm and 4.0 points at 180 cm.

3D body visualizer weight loss conversion chart

The 3D body visualizer weight loss view shows a weight change in kilograms or in pounds. One kilogram is 2.2046 pounds.

At 170 cm (5 ft 7 in), every 10 kg (22 lb) is 3.5 BMI points.
Weight change	In pounds	BMI points at 170 cm
1 kg	2.2 lb	0.3
2 kg	4.4 lb	0.7
5 kg	11.0 lb	1.7
10 kg	22.0 lb	3.5
13 kg	28.7 lb	4.5
15 kg	33.1 lb	5.2
20 kg	44.1 lb	6.9

For the steps between 2 weights, line up one height at five weights. To set 2 different people against each other, put two bodies side by side. The BMI visualizer draws one height at every BMI category.

Questions people ask

Does the 3D body visualizer show how I will look after weight loss?

No. The 3D body visualizer shows the model's typical body at 2 weights. Two people with the same numbers can carry their weight differently, so the figures do not predict how one person's body will change.

How much smaller is the waist after 13 kg of weight loss?

On the opening figure, 13 kg (28.7 lb) of weight loss takes the model's waist estimate from 96.1 cm to 83.0 cm, a change of 13.1 cm (5.2 in).

The figure is 170 cm tall and goes from 85 kg to 72 kg. Another height or another starting weight gives another change.

Can I set the goal weight in pounds or stone?

Yes. The units switch offers kilograms, pounds, or stone and pounds. The opening goal of 72 kg is 159 lb, or 11 st 5 lb.

Can the same view show weight gain?

Yes. Set the goal weight above the current weight. The outline is then larger than the solid figure, and the change column of the table shows positive numbers.

Is the goal weight a recommendation?

No. The tool draws whatever 2 weights are typed and recommends none.

The results list the weights that give a BMI of 18.5 to 24.9 at the height entered, which is the CDC's healthy weight category. At 170 cm that range is 53.5 kg to 72 kg. A doctor or nurse can assess your own health in person.
