Meet Mark & Claire
We're both in our forties, living in Yorkshire with our two dogs. You might know us from TheFatJabbers Instagram page. We used to be proper foodies, but these days we've replaced our meal times with business meetings.Mark's been trying to lose weight for years through ManVFat football and Claire's GLP-1 journey started after seeing Mark's results. Claire's an amputee, which makes BMI calculations pretty funny — missing part of your body tends to complicate the maths!
Professional mistake-makers turned snack curators
Built by people on the journey — for people on the journey
SidekickBox was created after Mark's month 2 Mounjaro disaster — £200 worth of full-size products that either made him gag or did absolutely nothing. Claire watched this expensive trial-and-error unfold and said, "What if people could try small amounts first?" That lightbulb moment became SidekickBox.
This is a subscription box with heart. No fads. No fluff. Just real-talk wellness tools from two people in Yorkshire who get it.
Your sidekick when your gut’s got drama and your fridge looks scary.
