Not a Punishment, Just a Reset
Christmas is wonderful. It is also, if we are honest, a fairly reliable disruption to routine, nutrition habits, and pretty much everything else you have worked to build over the previous months. That is fine. It is one stretch of the year. The goal is not to white-knuckle your way through December – it is to get back on track in January without turning the reset into a punishment.
We have done this twice now since surgery in March 2024, and the second year was noticeably easier than the first. Not because January was less difficult, but because we knew what was coming and had a plan before we needed one.
Start with Habits, Not the Scale
After a period of eating differently – more sugar, more salt, more volume than your sleeve usually handles comfortably – the best guide for your reset is not the scale. It is how you feel. Energy levels, sleep quality, digestion, mental clarity. These all respond quickly to getting back to better habits, and tracking them gives you positive feedback that is more useful than a number that is temporarily elevated by water retention and glycogen.
Give it two to three weeks before you take a post-Christmas weight reading seriously. In the meantime, focus entirely on behaviour: protein first at every meal, supplements taken daily, hydration consistent, alcohol back to a manageable level or stopped altogether for a few weeks.
Ease Back In Rather Than Crash Back
The instinct after a disrupted period is to impose severe restrictions as a kind of penance. In practice this tends to backfire – hunger and deprivation increase cravings, and a cycle of restriction and overeating is harder on your relationship with food than a gradual return to normal habits. Eating what works for your sleeve, consistently, is the reset. It does not need to be stricter than that.
Kirsten found that the first week of January was easiest when she approached it as simply returning to her normal routine rather than starting a new phase. The framing matters more than it sounds.
Supplement Compliance Is the First Priority
Supplementation often slips over Christmas – the routine is different, pills are packed away, there is a lot else going on. Getting back onto daily bariatric supplements from the first week of January is the highest-impact single action you can take. The effects of patchy supplementation are slow to appear but cumulative, and January is the point where the previous month’s gaps start to matter.

About this content
This blog is written by James and Kirsten, a couple from the UK who had gastric sleeve surgery together in March 2024.
We started this blog because we couldn't find any sources of content that details before surgery, the surgery and then life post surgery - so we decided to write one ourselves.
Everything on this site is based on our own experience and the research we have done along the way. It is not medical advice. Gastric sleeve surgery is a serious procedure and every patient's journey is different. Please always consult your own bariatric team or GP before making any decisions about your health or treatment.
