When Cooking Actually Started to Matter
Before surgery, cooking was functional. It produced meals. Some of them were good; most of them were adequate. It was not something either of us had invested in particularly. Post-op, with small portions, a focus on protein, and a new sensitivity to how food is prepared and seasoned, the ability to actually cook well suddenly mattered in a way it had not before. We have learned a lot since surgery that we wish we had known going in.
Seasoning Properly
When you are eating a small amount of something, the flavour has to work harder. A bland chicken breast that you could eat a large portion of pre-op and barely notice becomes quite unpleasant when it is the only thing on your plate and you are eating it slowly. Learning to season confidently – using herbs, spices, marinades, and acid like lemon juice or vinegar to build flavour without relying on heavy sauces or large quantities – transforms post-sleeve eating. Food that tastes genuinely good in small amounts is food you actually want to eat, which matters when appetite is low and eating can feel like a chore in the early months.
James in particular went through a period of finding eating deeply unenjoyable around months two and three. Getting better at flavour was part of what made it manageable.
Cooking Protein Without Drying It Out
Overcooked protein is unpleasant to eat at the best of times. Post-sleeve, when you are eating slowly and chewing thoroughly, dry chicken or tough meat becomes genuinely difficult to get through. Learning to cook chicken properly – understanding internal temperature rather than guessing, resting meat before cutting it – was one of the most practically useful things we did. A meat thermometer is a small investment that makes a significant difference.
Low and slow cooking methods – slow cooker, oven braising, poaching – tend to produce more forgiving results than high-heat methods, particularly in the early months when the sleeve is most restrictive.
Batch Cooking and Portioning
Cooking a small amount every meal is time-consuming and often leads to poor choices when hunger and tiredness collide. Learning to batch cook – preparing a larger amount of protein at once and storing it in portion-sized containers – made the day-to-day significantly easier. The skill is partly cooking and partly planning: knowing what you are going to eat before you are hungry is almost a prerequisite for eating well post-op.
We both now cook in batches most weeks. It took a few months post-op to get into the rhythm of it, and we wish we had started practising the habit before surgery rather than working it out during recovery.
Adapting Recipes Rather Than Following Them
Most recipes are not written with bariatric portions or protein priorities in mind. Being able to look at a recipe and modify it – swapping ingredients for higher-protein versions, reducing serving size, adjusting cooking method – is a more useful skill than following recipes precisely. It is less about cooking being a creative act and more about being flexible enough to make the food you actually need rather than what a recipe tells you to make.

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.
Some posts on this site may contain featured or sponsored content, or affiliate links. Where this is the case, it will always be clearly stated at the top of the article. Our opinions are always our own.
