For most consumers, comparing foods means scanning front-of-pack claims and marketing messages. For Keith O\u2019Beirne, founder of No Nonsense Fitness<\/a><\/strong> (NNF), that approach leaves too many unanswered questions.<\/p>\n The Irish entrepreneur has developed Protein Swap Lab, a free online food comparison tool that allows users to compare supermarket products on the same protein or calorie basis, helping people better understand the nutritional trade-offs behind their food choices.<\/p>\n The platform forms part of a wider mission to make fitness, nutrition and health education more accessible and easier to understand.<\/p>\n \u201cI built Protein Swap Lab, a free Irish food-label comparison tool that lets people compare selected foods on the same protein or calorie basis instead of relying on front-of-pack claims,\u201d said O\u2019Beirne.<\/p>\n \u201cThe method is deliberately transparent: preparation state is preserved, selected products aren\u2019t presented as market averages, and every result can be traced to the label data. It is an attempt to make everyday supermarket comparisons easier to inspect.\u201d<\/p>\n \u2022 200m+<\/strong> MyFitnessPal community members worldwide<\/p>\n \u2022 100m+<\/strong> Android downloads for MyFitnessPal<\/p>\n \u2022 56%<\/strong> of Irish adults living with overweight or obesity<\/p>\n \u2022 \u20ac9.99<\/strong> planned monthly subscription price<\/p>\n \u2022 25g protein<\/strong> comparison standard within Protein Swap Lab<\/p>\n \u2022 Up to 4 foods<\/strong> compared side-by-side<\/p>\n \u2022 255g yoghurt<\/strong> needed for 25g protein in Tesco Finest 0%<\/p>\n \u2022 166 calories<\/strong> for that 25g protein serving<\/p>\n \u2022 410g yoghurt<\/strong> needed for 25g protein in Tesco Finest full-fat<\/p>\n \u2022 541 calories<\/strong> for the equivalent full-fat serving<\/p>\n Editorial takeaway:<\/strong> The figures underline both the scale of demand for nutrition tools and No Nonsense Fitness\u2019s focus on helping consumers understand the calorie and protein trade-offs hidden behind food-label claims.<\/p>\n<\/div>\n The idea emerged from a simple observation. While food manufacturers increasingly promote products as being \u201chigh protein\u201d, consumers are often left without sufficient context to understand what those claims mean in practical terms.<\/p>\n \u201cFood labels are a good example,\u201d O\u2019Beirne explained. \u201cSomething can be marketed as \u2018high protein\u2019, but that doesn\u2019t tell you how much you would need to eat to get 25g of protein or how many calories come with it. I want people to be able to check the numbers, understand the trade-offs and make their own decisions.\u201d<\/p>\n Protein Swap Lab allows users to compare up to four foods at a time using equal protein amounts, equal calorie amounts or custom portion sizes. The calculations are based on published label data and are fully visible to users.<\/p>\n One example highlighted by O\u2019Beirne compares two Tesco Finest Greek yoghurt products. According to the listed nutritional values, obtaining 25g of protein would require around 255g of the 0% fat version for approximately 166 calories, compared with roughly 410g of the full-fat version for about 541 calories.<\/p>\n \u201cThe tool doesn\u2019t call one food \u2018good\u2019 and another \u2018bad\u2019; it shows the trade-off,\u201d he said.<\/p>\n Protein Swap Lab is the first public element of a broader ecosystem that includes free calculators, nutrition resources and training guides designed to support people at different stages of their fitness journeys.<\/p>\n Those resources include the Day One starter pack, the Year Two training guide and the Protein Hub, all of which are available free of charge and without requiring users to provide an email address.<\/p>\n At the centre of O\u2019Beirne\u2019s ambitions is the planned launch of the No Nonsense Fitness mobile app, which he intends to position as an educational alternative to traditional calorie-counting platforms.<\/p>\n \u201cI am still pre-revenue, so I wouldn\u2019t invent a commercial market-size figure, but it\u2019s clearly a large and established category,\u201d he said.<\/p>\n The planned app will be priced at \u20ac9.99 per month and will initially focus on Irish and UK consumers.<\/p>\n Among the application\u2019s standout features is a tool designed to help users understand how processed their food is.<\/p>\n Called \u201cHow processed is your food?\u201d, the feature will display a product\u2019s NOVA processing classification alongside its nutritional information when users scan or log a food item. Ingredient-label scanning will be used to help classify products where information is incomplete.<\/p>\n A second flagship feature, NNF Coach, has been designed as an educational tool rather than a traditional coaching service.<\/p>\n \u201cRather than generic motivational messages, it looks at the days the user has actually logged and produces a simple weekly educational review, what went well, what pattern stood out and one manageable thing to focus on next,\u201d O\u2019Beirne said.<\/p>\n \u201cIt\u2019s automated education, not a human coaching service or a health score.\u201d<\/p>\n Additional functionality will include barcode scanning, meal-photo tools, saved meals and a food database tailored towards Irish and UK grocery products.<\/p>\n The inspiration for No Nonsense Fitness came from O\u2019Beirne\u2019s own health and fitness experience.<\/p>\n Alongside his role as Head of Sales and Customer Success at Greyhound Recycling, where he has worked for 14 years, he began rebuilding his personal fitness after recognising his own health habits had drifted.<\/p>\n \u201cI had let my own fitness slip and was over 90kg. Learning how to train and eat in a way I could actually sustain took me to 72kg,\u201d he said.<\/p>\n As friends and colleagues began asking how he achieved the change, he identified a broader issue.<\/p>\n \u201cI realised how many people were being left confused by competing diets, exercise advice and expensive options.\u201d<\/p>\n That experience ultimately led him to launch No Nonsense Fitness.<\/p>\n \u201cSo I built the resource I wish I\u2019d had.\u201d<\/p>\n Unlike many venture-backed technology start-ups, No Nonsense Fitness is being developed alongside a demanding career and family life.<\/p>\n O\u2019Beirne is currently not seeking investment and remains focused on product development and validation before considering outside funding.<\/p>\n \u201cMy focus is getting the product ready, seeing what people actually use and proving the business model before considering outside investment,\u201d he said.<\/p>\n His long-term vision extends beyond individual consumers.<\/p>\n \u201cThe aim is to keep the core guides and tools free, offer an affordable app for people who want more day-to-day help, and eventually bring practical food, movement and strength education into Irish workplaces through a planned employer programme.\u201d<\/p>\n The development journey has already involved multiple revisions.<\/p>\n \u201cI\u2019m already on version five of the app before launch,\u201d O\u2019Beirne said.<\/p>\n One lesson has stood out above all others.<\/p>\n \u201cThe biggest lesson is that having ideas is easy; deciding which ones actually make the product clearer and more dependable is harder.\u201d<\/p>\n He also believes transparency around nutrition data will become increasingly important as health technology evolves.<\/p>\n \u201cI\u2019ve also learned that scale means very little if the underlying data can\u2019t be trusted. A huge food catalogue sounds impressive, but I care more about showing where information came from, keeping source links where possible and being honest about the limits of a calculation.\u201d<\/p>\n \u201cIf somebody can\u2019t understand or check the result, I haven\u2019t explained it well enough.\u201d<\/p>\n Like many modern entrepreneurs, O\u2019Beirne has embraced artificial intelligence tools as part of the development process.<\/p>\n He uses Claude and Codex to assist with planning, software development and code reviews, while GitHub and automated testing help track changes and identify issues.<\/p>\n Yet he remains clear about where responsibility lies.<\/p>\n \u201cAI helps me move faster, but I\u2019m responsible for what goes live and what claims I make about it.\u201d<\/p>\n That philosophy also informs the advice he offers to other aspiring founders.<\/p>\n \u201cDon\u2019t wait for a perfect gap in your diary. I started around a full-time job and two kids, one useful piece at a time.\u201d<\/p>\n \u201cDon\u2019t spend months polishing something nobody has tested yet. Get the useful part in front of people, listen and improve it.\u201d<\/p>\n And when progress stalls?<\/p>\n \u201cSometimes the best thing you can do when you\u2019re stuck is leave the desk for a walk or training session. I\u2019ve solved plenty of problems that way.\u201d<\/p>\n Protein Swap Lab is a free online food comparison tool created by No Nonsense Fitness founder Keith O\u2019Beirne. It allows users to compare selected foods based on the same protein amount, the same calorie amount or custom serving sizes.<\/p>\n Users can compare up to four food products at once. The tool uses nutrition label data to calculate how much of each food is needed to deliver a specific protein target or calorie amount, making comparisons easier to understand.<\/p>\n The tool was designed to help consumers look beyond front-of-pack marketing claims and better understand the nutritional trade-offs between foods using transparent, traceable label data.<\/p>\n Rather than simply tracking calories, Protein Swap Lab shows how foods compare on a protein-for-calorie basis and displays the calculations behind the results, helping users make more informed decisions.<\/p>\n The tool is aimed at adults in Ireland and the UK who want practical support with weight management, muscle gain, fitness goals and everyday food choices.<\/p>\n No Nonsense Fitness is an Irish health and fitness platform founded by Keith O\u2019Beirne. It provides free nutrition tools, training resources and educational content, with a subscription app currently in development.<\/p>\n Planned features include Irish and UK food search, barcode scanning, meal tracking, food processing information, meal-photo tools and an educational AI-powered coaching feature called NNF Coach.<\/p>\n The planned app will display a food\u2019s NOVA classification, helping users understand how processed a product is alongside its nutritional information and calorie content.<\/p>\n No. The company is pre-revenue and is currently focused on product development, user adoption and validating its business model before considering external investment.<\/p>\n The company aims to keep its core guides and tools free, offer an affordable subscription app and eventually deliver nutrition, strength and movement education programmes within Irish workplaces.<\/p>\n \u00a0<\/p>\n Keith O\u2019Beirne\u2019s No Nonsense Fitness has launched Protein Swap Lab, a free Irish tool that helps consumers compare foods by protein, calories and labels.
