Will yoga change my weight?

Usually very little, which is why this scenario models weight as unchanged and moves composition instead. A projection that promised substantial weight loss from yoga alone would not match the calorie maths.

Why is the projected change so small?

Because it is. Yoga at a stable weight produces a modest composition shift, and the model scales its coefficients to your horizon rather than front-loading a large change. The value of the number here is that it is not inflated.

Can it account for posture or flexibility?

No, and it does not claim to. Those are not derivable from the inputs the model takes.

Your yoga projection, in numbers — over 12 weeks

Twelve weeks is the classic training block. It is long enough for measurable composition change and short enough to stay motivating, which is why it is the most common horizon chosen on this site. A yoga practice usually does not change your weight much. This page models what it does change — a gradual composition shift and a modest tightening of circumference measurements at a stable weight.

Adherence over twelve weeks matters more than the precision of any single week. The projection assumes you hold the plan throughout.

A small, quiet change — modelled honestly as small

At a maintained weight, the model reduces body fat by roughly one percentage point across a 24-week horizon, scaled to your chosen horizon, and applies small tightening coefficients to shoulder, chest, hips, arm and thigh. The waist follows body composition, so it narrows slightly.

Anyone selling a yoga transformation as a dramatic reshaping is overstating it. What is modelled here is deliberately modest, and the page will show you a modest number. If the projection looks undramatic, that is the honest output rather than a bug.

What the model cannot see

Posture, flexibility and how you carry yourself are a large part of why people practice yoga, and none of them are derivable from height, weight, age and sex. The report states this rather than inventing a posture score. Circumference values are anthropometric estimates, not measurements.

Where the numbers come from

Every number on this page comes from published sports-science formulas (Mifflin-St Jeor for basal metabolic rate, standard activity multipliers for total daily expenditure, and anthropometric regressions for circumferences). It is a calculation, not an AI-generated image and not a photograph.

Predictions are estimates for motivation, not medical, nutritional, or fitness advice. Circumference values come from anthropometric regressions based on your height, weight and body composition — not measurements.
