The Hidden Cost of Lunch on the Go: Energy, Focus and Money
A quick lunch can cost CHF 15. But the real cost doesn’t end at the checkout.
It shows up at 3 pm, when you read the same email three times and still struggle to focus. At 6 pm, when you skip your workout because you’re exhausted. And at the end of the month, when you look at your bank statement and realise how much you’ve spent on lunches out.
It’s rarely about one meal. It’s about the small food choices we repeat every day, often without thinking about them, and how they add up over time.
Your eating habits can affect how you feel, how you approach your working day and how much you spend on food.
The good news? You don’t need a strict diet or hours in the kitchen to make a difference. A little planning and a few practical changes can go a long way.
Let’s look at the hidden costs of eating at work and how to reduce them without making your life more complicated.
1. Energy: Why Do You Hit an Afternoon Slump?
It’s around 3 pm. You still have a long to-do list, but your concentration is fading. You’re craving another coffee, looking for something sweet and counting down the hours until the end of the working day.
The afternoon slump has a biological component. Our circadian rhythm naturally influences alertness, often leading to a dip in energy in the early afternoon. What you eat can also affect how you feel during this time.
A very large lunch, for example, may leave you feeling sleepy and sluggish. On the other hand, skipping lunch or eating too little can leave you feeling hungry and low on energy a few hours later.
The goal isn’t to eliminate every dip in energy. It’s to avoid adding factors that may make it worse.
What can help? Aim for a balanced lunch that includes vegetables, a source of protein and carbohydrates in amounts that suit your needs. And don’t forget to drink water throughout the day. Staying hydrated helps prevent dehydration, which can contribute to fatigue and difficulty concentrating.
2. Focus: Less Guesswork, More Consistency
Skipping lunch, reaching the afternoon feeling ravenous and relying on coffee and snacks to keep going is familiar to many busy professionals.
There is no universal rule that a particular food will automatically cause a drop in cognitive performance. Responses to meals vary, and research into the relationship between meal composition and mental performance is mixed.
In everyday life, however, a reasonably consistent eating routine can help you manage hunger and avoid reaching the end of the day feeling completely drained.
This doesn’t mean giving up coffee or snacks. It means not having to rely on them constantly to compensate for a day of eating too little, eating on the go or missing a proper break.
A lunch prepared in advance, a convenient snack and a water bottle on your desk are small changes that can make your working day easier to manage.
3. Recovery: It’s Not Just About Exercise
Recovery isn’t only relevant if you work out regularly. It also means being able to switch off after work, having energy for your personal life and waking up without feeling constantly exhausted.
Nutrition plays a role in overall wellbeing and may also influence sleep quality. Some studies have found associations between dietary patterns and aspects of sleep, but the evidence doesn’t allow us to automatically blame a restless night on what we ate for lunch.
If you exercise, consistently eating too little or struggling to meet your nutritional needs can also make it harder to recover between sessions.
That’s why it helps to look at your eating habits across the whole day, rather than focusing only on dinner or your post-workout meal.
The aim is to eat enough to support your needs throughout the day, instead of trying to make up for everything at the last minute.
4. Hunger and Decision-Making: When Convenience Takes Over
After a day full of meetings, deadlines and unexpected tasks, you get home hungry. There’s nothing ready to eat, you don’t feel like cooking and you have even less energy to decide what to make.
That’s when ordering takeaway, grabbing whatever is available or turning aperitivo into dinner can feel like the easiest option.
It isn’t necessarily a lack of willpower. When you’re tired and hungry, convenience matters. Having something ready to eat can make all the difference.
That’s why meal planning isn’t about controlling every bite. It’s about reducing the number of decisions you need to make when you have the least time and energy to make them.
Even preparing just two or three lunches in advance can help you avoid having to figure everything out from scratch every day.
How Much Does an Afternoon Slump Really Cost?
Let’s put the idea into numbers.
Imagine, purely as an illustration, that you lose 30 minutes of effective working time each day because of fatigue, distractions or difficulty concentrating.
30 minutes a day × 5 days = 2.5 hours a week.
2.5 hours × 46 working weeks = 115 hours a year.
115 hours is almost three 40-hour working weeks.
To be clear, this doesn’t mean that eating poorly automatically costs you 30 minutes of productivity every day. This is a hypothetical example showing how a small amount of time can add up over several months.
Workplace nutrition is also recognised as an international issue. In 2005, the International Labour Organization published a report estimating that inadequate nutrition could be associated with productivity losses of up to 20%.
This is a broad global estimate covering very different circumstances, including malnutrition. It should not be interpreted as a figure that automatically applies to someone who buys lunch at a café or occasionally skips a meal.
The underlying principle still matters: access to adequate nutrition at work is relevant both to employee wellbeing and to how workplaces function.

The Cost of Lunch in Switzerland: How Much Could You Save?
So far, we’ve looked at energy and time. But there’s another cost that’s much easier to measure: your lunch bill.
In Switzerland, buying lunch during the working week can make a noticeable dent in your monthly budget. A 2023 Swibeco survey of 325 participants found that 37% spent between CHF 10 and CHF 15 per day on lunch, while 20% reported spending more than CHF 30.
These figures relate to a specific survey sample rather than the entire Swiss workforce, but they illustrate how quickly the habit of buying lunch every day can add up.
Preparing lunch at home can be a more affordable alternative. A pasta dish with chickpeas and vegetables, a grain and bean salad or a portion of homemade minestrone might cost around CHF 4–6 per serving, depending on ingredients, portion sizes and local prices.
Let’s calculate the potential savings, assuming an average cost of CHF 5 per homemade lunch and 46 working weeks per year.
The difference can be substantial. And you don’t have to bring lunch from home every day. Even preparing three lunches a week could help you save money while leaving room for the occasional restaurant lunch with colleagues.
There’s another advantage, too: when you prepare your own meals, you have more control over the ingredients and portions, allowing you to choose what suits your preferences and nutritional needs.
Healthy Work Lunches and Meal Prep: How to Get Started
Bringing lunch from home doesn’t have to become another demanding project on your to-do list. You don’t need to cook seven different recipes every Sunday or weigh every ingredient.
1. Build a balanced lunch
A simple starting point is to include
2. Keep water within reach
A water bottle on your desk is a simple reminder to drink regularly. Your fluid needs will vary depending on your activity level, the temperature and your individual circumstances.
3. Plan a snack before you need one
If there are several hours between lunch and dinner, it can help to have something convenient ready. Yoghurt, fresh fruit, nuts or bread with a protein-rich topping are all practical options.
Not everyone needs a snack. The important thing is finding a routine that works for you.
4. Don’t skip your lunch break to save time
Eating at your desk while continuing to work might feel efficient, but it doesn’t always give you a chance to switch off.
Whenever possible, take a proper break and give yourself time to eat. It doesn’t need to be long or perfect. Even a few minutes away from your screen can help create a clearer boundary between work and lunch.
5. Set aside an hour a week for meal prep
Meal prep means preparing some meals or ingredients in advance to make the following days easier.
You could cook a batch of beans or lentils, roast a tray of vegetables and prepare some rice or other grains. During the week, combine them in different ways to create quick lunches and dinners.
As an Italian, I’m also a big fan of making a pot of minestrone at the weekend. It can take care of more than one dinner, provided it’s stored safely and divided into portions.
You don’t have to organise the entire week at once. Start with two lunches and build from there if it works for you.

When Nutrition and Meal-Prep Coaching Can Help
Knowing what to eat is one thing. Putting it into practice when you have meetings, deadlines, family commitments and very little time is another.
This is where a system built around your actual routine can help. Not a rigid diet you have to follow perfectly, but a sustainable approach that fits your schedule, preferences and kitchen.
