Why skipping meals is doing you more harm than good
Some people assume that skipping meals can be an easy way to lose weight quickly. It seems logical that this could work, and while you might only consider missing the odd breakfast and lunch here or there, you don’t see the harm. However, never miss meals, and here I share why.
But doing this can have a negative impact on any weight loss journey and cause more harm than good. If you are wondering why this could be the case, then here are some of the reasons why you should never miss meals, my experiences, and the evidence.
Your blood sugar levels can drop
The meals you eat significantly impact your energy levels. If you eat too much, or in this case, don’t eat at all, then this can significantly affect your blood sugar levels and cause them to drop. If this happens, you can start to feel lethargic and weak.
It can also affect your mood, making you feel tired and dizzy. Nobody wants to feel this way, and regular mealtimes can help to keep your energy levels where they should be.
I have also found that if I have a late breakfast, my energy levels in the morning are much lower until the nutrients enter my bloodstream after I have eaten! What do you think? Is this something you have experienced?
Never miss meals, it can slow down your metabolism
In some cases, skipping a meal can have the opposite effect of what you are trying to achieve. In your mind, a meal skipped is one less meal to digest, but it can impact your metabolism in the wrong way, which is why you should never miss meals.
A faster metabolism means you burn off food and calories far more quickly, skipping meals means your body won’t function as it should, causing your metabolism to slow right now. This can make it harder to lose weight in the long run.
You could be missing out on vital nutrition
We all need a certain amount of nutrients and vitamins in our bodies to function as we should, but skipping meals means we are not giving our bodies the best possible chance.
You could be missing out on vital nutrients that you would have gained from balanced meals throughout the day. In the long term, this could cause issues with your immune and digestive systems. If you never miss meals, the chances of missing out on essential nutrients are much smaller.
Increases the risk of diabetes
Going without breakfast or lunch can often mean that your glucose levels need to rise. Doing this regularly means you are increasing your risk of getting diabetes in the future. This could cause you more harm than good. Diabetes is not a pleasant thing to experience and is a lifelong issue that needs to be managed. If you never miss meals, you can still develop Type 2 Diabetes, but the likelihood is slightly lower than in people who miss meals regularly.
It can mess up your mealtime routine
It can mess up your routine at mealtimes. Instead of getting hungry at obvious times of the day where you would normally eat, it might mean that you end up hungry in the middle of the night or afternoon, when it is less convenient to eat a meal. This can also cause lasting damage, leading to a rise in your glucose levels.
Your mood and concentration take a hit
Have you ever noticed that you get short-tempered when you have not eaten? There is a reason the word “hangry” made it into the dictionary.
Your brain runs almost entirely on glucose. When levels fall, your ability to concentrate drops, your mood dips, and you are more likely to feel anxious or irritable. The British Dietetic Association (BDA) acknowledges the connection between what we eat and how we feel, noting that diet can have a real impact on mood and mental wellbeing.
Keeping blood sugar stable through regular meals is one of the most straightforward things you can do for your mental clarity and general mood throughout the day.
It can lead to overeating and disordered patterns
Skipping meals regularly can set up an unhealthy cycle. You skip, you get ravenous, you overeat, you feel guilty, you skip again. Over time, this kind of pattern can start to blur the line between normal dieting behaviour and something more difficult to manage.
The NHS notes that eating very little food and having very strict food habits or routines are warning signs worth paying attention to. If you find that skipping meals is becoming a regular habit tied to anxiety about weight or body shape, it is worth speaking to your GP.
If you are trying to lose weight, the goal is always sustainable eating, not restriction. You will make much more progress by eating regular, balanced meals than by going long stretches without food. Never miss meals, just change them.
Breakfast really does matter
Breakfast gets skipped more than any other meal, often by people who are rushed, not hungry first thing, or who believe they will save calories by waiting. But the evidence suggests starting the day with something to eat has real benefits.
The BDA’s healthy breakfast guidance states that a healthy breakfast can provide essential nutrients, sustained energy and many health benefits, from improved focus to weight management.
If you genuinely struggle with ideas for what to eat, I have over 90 breakfast ideas, covering everything from porridge and overnight oats to cooked breakfasts and egg muffins. There is something for every level of morning motivation.
What about intermittent fasting?
This is a fair question, because intermittent fasting (IF) has become very popular and essentially involves skipping meals in a structured way. So does everything above still apply? Why do we say never miss meals if a diet plans specifically asks you to?
The key difference with intermittent fasting is that it is deliberate and planned. When you follow a method like 16:8 (eating within an 8-hour window), your body adapts to the eating pattern over time. You are also still eating proper meals within that window, not just cutting out food entirely and snacking randomly later.
The BDA’s review of time-restricted eating suggests the evidence for IF is promising but mixed, and highlights that it may not suit everyone. It is not the same as casually skipping meals because you are busy or because you think it will speed up weight loss.
If you are thinking about trying intermittent fasting, it is worth speaking to your GP first, particularly if you have any underlying health conditions.
Practical tips for eating more regularly
If your days tend to run away from you and meals get forgotten or pushed aside, here are some simple ways to make regular eating easier so you never miss meals.
Plan your meals in advance. Knowing what you are going to eat at each meal removes the friction that leads to skipping. A weekly meal plan does not have to be complicated. Even having a rough idea of what breakfast and lunch will look like can make a big difference.
Prepare ahead where you can. Making overnight oats the evening before, or packing a lunch the night before, takes the pressure off busy mornings. My busy mum’s guide to weight loss has some great practical advice for fitting regular eating around a hectic schedule.
Keep healthy snacks handy. The BDA recommends planning snacks in advance so that when hunger hits, you are reaching for something nutritious rather than whatever is nearest. Carrot sticks, a piece of fruit, a hard-boiled egg, or a small handful of nuts are all solid choices. Keep them where you can see them.
Do not skip meals to save calories. As we have covered, this tends to lead to increased overall eating. A regular, balanced meal is nearly always a better strategy than going without.
Eat with others where possible. Eating at the table rather than on the go, and with other people when you can, helps make meals feel intentional rather than optional. It means you never miss meals as you plan them with others.
Frequently asked questions
Is it really that bad to skip breakfast?
For most people, yes. Skipping breakfast is linked to lower energy, poorer concentration, and a tendency to overeat later in the day. That said, if you genuinely are not hungry first thing in the morning, a small something is still better than nothing. Even a piece of fruit or a yoghurt helps.
Can skipping meals help with weight loss?
It is tempting to think so, but the evidence does not really support it. Most people who regularly skip meals end up eating more overall because hunger drives them towards high-calorie foods later. Steady, regular eating tends to produce better and more sustainable results, just never miss meals.
What if I am just not hungry at mealtimes?
This can happen for all sorts of reasons, from stress to irregular sleep to simply eating out of habit rather than hunger. If you are regularly not hungry at mealtimes, it is worth looking at whether you are snacking too much between meals, eating late at night, or whether something else is going on worth discussing with a GP.
How long is too long to go without eating?
As a general guide, try not to go more than four to five hours between meals or snacks. Going longer than this is when blood sugar tends to dip noticeably, bringing with it tiredness, irritability, and the urge to grab whatever is quick and filling.
Is skipping meals a sign of an eating disorder?
Not necessarily, but it can be one part of a wider pattern worth paying attention to. If skipping meals is tied to anxiety about weight or body shape, or has become a rigid habit, it is worth speaking to your GP. The NHS eating disorders page has more information and guidance.
Making regular meals work for you
The idea that eating less often is the key to a healthier weight or body is one of those myths that refuses to go away. In practice, regular meals keep your blood sugar steady, support your mood and concentration, and make it far easier to avoid the kind of hungry-fuelled overeating that derails most attempts at healthy eating. The solutions is to never miss meals but instead watch what you do eat.
You do not need a complicated plan or perfect meals. You just need to eat something at regular intervals that your body can work with. Start there, and the rest tends to follow.
It isn’t a good idea to skip meals, so never miss meals or combine two normal meals into one large meal. Let’s hope sharing some reasons will encourage you to adopt a balanced, healthy approach to your meals.
