Explainer scripts
14 full scripts for 65-85 second explainers — hook, timed beats, on-screen text, voiceover and every figure they show, computed from the live food and exercise data. Scripts, not videos: nothing here is watchable yet, and the page says so.
There are no videos here yet, and this page does not pretend otherwise. TempoLife has published no explainer videos, so nothing on this surface is watchable and there is no player anywhere on it. What is published is the script library: the full storyboard for each explainer, ready to shoot.
Why there is no player on this page
The registry entry for this surface promises short explainers with transcripts. Before building it, the repository was searched for anything playable. There is none: the only video files here are a twenty-second app promo and three paid-advertisement aspect ratios, and the one tool that can publish video — a renderer for weekly news Shorts — leaves no record of a published video anywhere in the codebase.
Two options followed from that. Embed a player pointed at files that do not exist, or publish what does exist. What exists is the writing: fourteen complete storyboards with timed beats, on-screen text, voiceover, visual direction, production notes and the exact figures each script puts on screen. A script is genuinely useful to read — most of these explain the topic faster than a video would — and it is ready for a camera the day someone picks one up.
So this page is labelled a script library everywhere it could be mistaken for something else, and there is no <video>, no <iframe> and no play button anywhere on the surface. When a script is shot, the video goes on its own page and this notice comes down for that one.
The scripts
| Script | Runtime | Beats | What the viewer leaves with |
|---|---|---|---|
| What a calorie actually is | 75s | 7 | By the end the viewer can say what a calorie measures, and why the same word describes a biscuit and a flight of stairs. |
| BMR vs TDEE, in one worked example | 85s | 7 | The viewer leaves able to explain the difference, and knowing that the activity multiplier is where the error lives. |
| The one column people read wrong on a label | 70s | 6 | The viewer stops comparing a per-100g column to a per-portion column, which is the most common shopping error there is. |
| Ranking foods by protein per 100 calories | 80s | 6 | The viewer learns to judge a protein source by its cost in calories, not by whether it is "a protein food". |
| Why the scale jumps two kilos overnight | 80s | 6 | The viewer stops interpreting daily scale noise as fat gained or lost, and knows what the noise is made of. |
| Where 10,000 steps came from | 75s | 6 | The viewer learns the target is a marketing number, that the health benefit curve bends much earlier, and what their own steps are worth in calories. |
| Walking vs running: per minute and per kilometre | 80s | 6 | The viewer understands why running wins per minute and the gap narrows per kilometre, and can pick on that basis. |
| What a MET is, and why every calorie chart uses it | 75s | 6 | The viewer can read any MET table and convert it to calories for their own body weight. |
| How much sugar is in a can, in teaspoons | 65s | 6 | The viewer converts a grams-of-sugar figure into something they can picture, and does it themselves next time. |
| How much protein you actually need | 80s | 6 | The viewer leaves with a target in grams for their own body weight, and a sense of what that looks like on a plate. |
| Where fibre actually is | 75s | 6 | The viewer can name three foods that genuinely move their fibre intake, and stops relying on products marketed as high-fibre. |
| Estimating a portion without scales | 70s | 6 | The viewer gets a hand-based estimate they can use in a restaurant, and an honest sense of how wrong it can be. |
| Sleep debt, and whether you can pay it back | 75s | 6 | The viewer can compute their own weekly sleep debt and knows what a weekend lie-in does and does not fix. |
| The deficit arithmetic nobody shows you | 85s | 6 | The viewer can convert a daily deficit into a weekly rate, and calibrate their expectations against arithmetic instead of advertising. |
How each script is built
Same skeleton every time, because the constraint is what makes them shootable. A hook in the first four seconds that states the surprise rather than promising one. Beats of ten to twenty seconds, each with its own on-screen text, because most viewing is muted and the text carries the argument. One number that lands full-frame and holds. A closing line that is an instruction, not a slogan.
Every figure a script shows is listed on its page with its live value and its provenance, computed when the page loads from the same 5 237 food rows and 31 exercise rows behind the rest of this site. That means a script cannot quote a number that has since changed in the data, and a producer reading it gets the current figure rather than the one that was true when it was written.
None of these scripts names a study, a brand or a person. Where a claim rests on a body of evidence, the voiceover says so in the direction the evidence points and the production notes say explicitly not to put a citation on screen. That is a deliberate constraint: a fifteen-second beat cannot carry the caveats a citation would need.

Frequently asked questions
Can I watch these?
No. None of them has been shot. That is stated on this page and on every script page, and there is no player anywhere on this surface.
Can I use these scripts?
They are published so they can be read. If you want to produce one, get in touch through the support page first — the figures need to stay attached to their sources.
Where do the numbers on screen come from?
Every script page carries a table of the exact figures it shows, each with its live value and where it came from. They are computed when you load the page, not stored in the script.
Why are they all 65-85 seconds?
Long enough for one idea and one number, short enough to hold attention. Each script is one claim; anything that needed two became a second script.

The numbers in these scripts, for your own day
Every figure in this library is a population average. TempoLife records yours — meals, steps, sleep and weight in one timeline.
