Why is this different from the score in my browser?
This view grades the mobile run. Lighthouse 13.4.1 runs at Google through the PageSpeed Insights API on an emulated mid-range Android with a 4× CPU slowdown and a throttled connection. Chrome DevTools on your own machine, on the Desktop preset, applies almost none of that, and the same page routinely scores 30–50 points higher there. Neither number is wrong — they are different tests.
Mobile is what Google ranks on, so this is the number that affects your
search performance. This report predates the desktop-graded headline: only the mobile run was graded. To reproduce it, open the same run on PageSpeed Insights,
or pass strategy=mobile to the PageSpeed API — it defaults to desktop.
Lighthouse also varies a few points run to run on the same URL. Treat a trend across several scans as the signal, never a single digit.
Lab data: Google PageSpeed Insights (Lighthouse, mobile). Server probes (TTFB, compression, cache, headers) are measured separately from Vilnius, Lithuania (EU).

11 of these checks map to an xSpeed feature. thediettherapy.com's report indicates that xSpeed MCP is available. This scan did not verify client credentials; if your client is configured and authenticated, use this prompt:
If you are authenticated to my site's xSpeed MCP server, read the failing checks from https://xspeedcache.com/scan/r/thediettherapy-com-404230d389.md, apply the fixes: enable page caching, compression, minification and lazy loading, warm the cache, then run a benchmark and re-scan at https://xspeedcache.com/scan to confirm the score improved.Hosting is the other half.
xSpeed makes any host faster, but a cache is only as fast as the server behind a MISS.
xCloud — managed hosting from the team behind xSpeed — gives the cache an origin tuned for it, with agent/MCP access built in and bring-your-own-server pricing.
