Planning 3
- Know your current baselineTrack your weight and note any recent unintentional loss.Why it matters: Weight change is easier to act on early, and a baseline is what makes a change visible at all.
- Review eating challengesConsider appetite, fatigue, chewing, swallowing, and the effort of preparing meals.Why it matters: Eating less is often about effort and tiredness rather than appetite, and the fix differs for each.
- Ask for practical nutrition supportDietitian input can help maintain intake and reduce mealtime stress.Why it matters: Specific, practical advice takes far more pressure off than trying to eat more in general.

Eating well and keeping a steady weight is a genuinely important part of living with ALS/MND. It matters more than it might first seem.
There are a few reasons it matters:
- Energy. ALS/MND can use up more energy than usual, and the effort of moving, breathing and even eating adds to that. Good nutrition helps you keep the energy you have.
- Strength and resilience. Losing weight in ALS/MND often means losing muscle and reserve, which can leave you feeling weaker and less able to cope with setbacks like an infection.
- Wellbeing. Eating affects mood, comfort and the simple pleasure of meals and time with others.
On survival, the evidence is narrower than it is sometimes made to sound. The UK MND guideline lists weight loss among the prognostic factors that are associated with shorter survival if they are present at diagnosis, and asks teams to take those factors into account when planning care. The guideline does not say what weight lost later in the illness means for survival, so this is not a number anyone can put on your situation. Unplanned weight loss is still worth telling your team about promptly. What the guideline does recommend is that your team check your weight, diet and nutrition from diagnosis onwards and offer support as needed, so keeping your weight up is treated as a normal goal of care.
This is an association rather than a cure. Keeping weight up does not change the underlying condition. But it is one of the practical things that can genuinely help you feel and function better.
Because of this, your team will usually keep an eye on your weight and nutrition, and there is a lot that can help if eating becomes harder. The other questions on this card cover why eating can get more difficult, practical ways to keep your nutrition up, and where to get support. Swallowing safety and feeding tubes have their own cards.
Evidence for this answer
The sources the Compass team used to write this answer. Highlighted phrases in the answer above correspond to the statements below.
Statement 1 of 2. The UK MND guideline lists weight loss present at diagnosis among the prognostic factors associated with shorter survival, and asks teams to take those factors into account when planning care.
Supports this. NICE MND guideline — NICE · Clinical guideline
Recommendation 1.4.1 lists weight loss among six prognostic factors associated with shorter survival, and scopes that association to factors present at diagnosis. It is a baseline marker used for care planning: not a claim about weight lost later in the illness, and not a claim that preventing weight loss changes the disease.
“When planning care take into account the following prognostic factors, which are associated with shorter survival if they are present at diagnosis”
1.4.1Link checked August 2026
Statement 2 of 2. Weight lost in ALS/MND tends to include muscle, which leaves people weaker and with less energy.
Supports this. ALS Nutrition — Your ALS Guide · Practical guide
Says that weight lost because someone is not taking in enough calories speeds up muscle loss and brings weakness and low energy with it.
“The resulting weight loss can lead to accelerated muscle loss, weakness, low energy, and other issues.”

Weight change in ALS/MND is rarely about willpower or appetite alone. Several things can combine to make eating enough genuinely harder.
On the "taking in less" side:
- swallowing changes can make eating slower, tiring or harder (covered on the swallowing card)
- weaker hands or arms can make preparing food and getting it to your mouth difficult
- fatigue can mean meals get cut short, or are skipped when energy is low
- low mood, anxiety or taste changes can reduce appetite
- constipation or a feeling of fullness can put you off eating
On the "using more" side:
- ALS/MND can raise the amount of energy the body uses, even at rest, for some people, so the usual amount of food may no longer be enough
Put together, this can lead to unplanned weight loss even when nothing about your eating feels obviously wrong. That is worth knowing, because it means the answer is usually practical rather than simply "trying harder". It is about adjusting what and how you eat, getting help with the parts that are hard, and involving a dietitian.
It also means weight is worth keeping an eye on. The other questions on this card cover practical ways to keep your nutrition up, how monitoring works, and when extra support might help.
Evidence for this answer
The sources the Compass team used to write this answer. Highlighted phrases in the answer above correspond to the statements below.
Statement 1 of 2. For some people ALS/MND raises the amount of energy the body uses at rest.
Supports this. Hypermetabolism in ALS is associated with greater functional decline and shorter survival — Journal of Neurology, Neurosurgery and Psychiatry · Research review · 2018
Measured resting energy use directly in 58 people with ALS and 58 age and sex matched controls, comparing it with what each person's body composition predicts. Raised resting energy use was found in about four in ten of the ALS group and about one in ten of the controls, so it affects a substantial minority rather than everyone.
“Hypermetabolism was more prevalent in patients with ALS than controls (41% vs 12%, adjusted OR=5.4; p<0.01).”
ResultsLink checked August 2026
Statement 2 of 2. Taking in less while using more energy can combine to cause weight loss that was not intended.
Supports this. ALS Nutrition — Your ALS Guide · Practical guide
Gives the same two-sided picture: everyday activity costs more energy than it used to, and eating gets harder, so people take in fewer calories than they need and lose weight.
“Daily activities require more energy and calories than before, and when eating becomes more challenging, people living with ALS tend to consume fewer calories.”
ALS NutritionLink checked August 2026
Qualifies this. Hypermetabolism in ALS is associated with greater functional decline and shorter survival — Journal of Neurology, Neurosurgery and Psychiatry · Research review · 2018
Qualifies the using-more half of this. In the same study, weight, body mass index and fat mass changed no differently in the people with raised resting energy use than in the rest, and the authors say no study has yet shown that raised energy use itself causes greater weight loss.
“In contrast to the perception that hypermetabolism could be a primary cause for weight loss, there has been no study to definitively show that hypermetabolism contributes to a greater degree of weight loss in ALS.”

There is a lot you can do to keep your nutrition and energy up, and a dietitian can tailor it to you. Unlike general "healthy eating" advice, the goal in ALS/MND is often to make every mouthful count and to make eating easier.
Practical approaches people use:
- Eat little and often. Smaller meals and snacks through the day can be easier than three big meals, especially if eating is tiring.
- Add calories without adding bulk. Enriching food adds energy without much more to eat. That can mean extra butter, oil, cream, cheese, nut butters or full-fat options. A dietitian can suggest "food fortification" ideas.
- Use easy, energy-dense foods on low-energy days. For example smooth soups, yoghurts, milky drinks, or ready meals.
- Drink your calories when eating is hard. Options include milkshakes, smoothies, or prescribed nutritional supplement drinks a dietitian can arrange.
- Make eating less effort. That can mean softer, moist foods, help with preparation, adapted cutlery, and choosing meals when your energy is best.
If swallowing is also changing, the safest textures and approaches should come from a speech pathologist. Keep nutrition and swallowing advice joined up.
Some days will be better than others, and that is okay. If your weight is dropping, or eating feels like a constant effort, a dietitian can help you find an approach that works and is realistic. A feeding tube is one option to understand as well. It is usually raised early and revisited rather than kept back until eating by mouth is very hard, and it has its own card.
Explained: what this word meansEvidence for this answer
The sources the Compass team used to write this answer. Highlighted phrases in the answer above correspond to the statements below.
Statement 1 of 3. Enriching food lets someone take in more energy without eating a larger amount.
Supports this. ALS Nutrition — Your ALS Guide · Practical guide
Describes the same approach and the same foods: a dietitian works out how to get more calories in without a larger volume of food, using healthy fats, high-calorie drinks and additions such as butter, cream, cheese and whole milk.
“If you are having a hard time maintaining your weight, your dietitian will suggest ways to consume more calories without eating a significantly larger amount of food each day.”
Increase Your CaloriesLink checked August 2026
Statement 2 of 3. Eating smaller amounts more often through the day is an alternative to three larger meals.
Adds context. ALS Nutrition — Your ALS Guide · Practical guide
Recommends the same pattern, six smaller meals a day rather than three larger ones plus snacks between them, but gives it as a way to take in more calories. It does not say the pattern is easier or less tiring, which is the reason the answer gives.
“Other ways to consume more calories include eating six smaller meals a day instead of three larger meals, eating more snacks between meals, and adding protein powders to foods.”
Increase Your CaloriesLink checked August 2026
Statement 3 of 3. When swallowing is changing, which textures are safe should be decided by a speech pathologist rather than worked out at home.
Supports this. ALS Nutrition — Your ALS Guide · Practical guide
Gives the speech language pathologist this exact job, with the dietitian working alongside on keeping the modified food nourishing.
“Your speech language pathologist will make sure you are eating foods that are easy for you to chew and safe for you to swallow without choking.”
Modify Your FoodLink checked August 2026
Adds context. NICE MND guideline — NICE · Clinical guideline
The UK MND guideline requires a clinical swallowing assessment whenever swallowing problems are suspected, and puts modifying the consistency of food and drink among the things to assess and manage afterwards. It does not name which profession does the assessment, so it backs the referral rather than the job title.
“Arrange for a clinical swallowing assessment if swallowing problems are suspected.”

Keeping an eye on weight and nutrition is a routine part of ALS/MND care, because catching changes early gives the most options to help.
What monitoring usually involves:
- Weight checks at clinic visits, looking at the trend over time rather than a single number. Steady is reassuring; a downward trend is a prompt to look at what is going on.
- Questions about your eating. What you are managing, what has become harder, any swallowing or appetite changes.
- A dietitian's input if weight is dropping or eating is difficult, to work out a plan.
Many people find it helpful to weigh themselves at home every week or two and note it down, so changes are spotted between appointments. Using the same scales at the same time of day keeps the numbers comparable. If standing on scales is difficult, your team can suggest other ways to keep track.
It is worth telling your team promptly if you notice unplanned weight loss, that you are eating much less, or that meals have become a struggle. There is no need to wait for the next visit. Weight that is lost can be hard to regain, so getting support early usually gives you more options.
Monitoring is not about pressure or judgement. It is simply a way to make sure that, if eating becomes harder, help arrives in good time. What that help might look like is covered in the other questions on this card.
Evidence for this answer
The sources the Compass team used to write this answer. Highlighted phrases in the answer above correspond to the statements below.
Statement 1 of 2. Weight and nutrition are checked as a standing part of ALS/MND care, not only when a problem appears.
Supports this. NICE MND guideline — NICE · Clinical guideline
The UK MND guideline makes weight and nutrition a standing item. Recommendation 1.11.1 has teams assess weight, diet, nutritional intake, fluid intake, feeding, drinking and swallowing at diagnosis, at every multidisciplinary team assessment, and whenever a concern comes up, and offer support and interventions as needed. Recommendation 1.5.3 puts the same areas on the team's regular review list.

Statement 2 of 2. Weight that has been lost in ALS/MND can be hard to regain, so getting support early usually leaves more options open.
Supports this. ALS Nutrition — Your ALS Guide · Practical guide
Makes the same point from the other side: weight already lost may be hard to put back on, which is why changes are worth acting on early. It is a patient guide reviewed by an ALS clinical dietitian, not a study of whether earlier support produces better outcomes.
“If you ignore these signs and lose weight, it may be hard to gain the weight back.”

When chewing or swallowing gets harder, changing the texture of food can make eating easier, safer and less tiring. It can still be nourishing and enjoyable. Because the safe texture for you depends on your swallowing, this works best with a speech pathologist (for what is safe) and a dietitian (for keeping it nutritious) involved together.
Common adaptations:
- Softer, moister foods with plenty of sauce or gravy, such as slow-cooked dishes, casseroles, fish, eggs, soft fruit or yoghurt
- Mashing or blending meals so they need less chewing, while keeping flavours you like
- Avoiding tricky textures that are a problem for you, such as dry, crumbly, stringy or mixed (solid-plus-liquid) foods
- Adjusting drinks. Some people manage thicker drinks more easily than thin ones, and a speech pathologist can advise whether and how to thicken safely
A few things help keep adapted meals appealing: season well, keep different foods separate on the plate where you can, and make them look as good as they taste. Keeping the foods you love matters for both nutrition and morale. They can simply be served in a form that is easier.
The key is not to guess on your own, especially with drink thickness or if you are coughing at meals. Your speech pathologist and dietitian can build a plan that is safe, nourishing and still something to look forward to. Full swallowing strategies are on the swallowing support card.
Evidence for this answer
The sources the Compass team used to write this answer. Highlighted phrases in the answer above correspond to the statements below.
Statement 1 of 2. Which food textures are safe depends on the person's swallowing, so it is assessed rather than assumed.
Supports this. NICE MND guideline — NICE · Clinical guideline
The UK MND guideline treats food and drink texture as part of managing a swallowing problem. Recommendation 1.11.5 puts the need to modify food and drink consistency and palatability among the factors to assess and manage, alongside positioning, seating and the risk of aspiration and choking, and 1.11.4 sends anyone with suspected swallowing problems for a clinical swallowing assessment first.
Link checked August 2026
Statement 2 of 2. Some people manage thicker drinks more easily than thin ones.
Supports this. Eating and ALS — Your ALS Guide · Practical guide
Suggests thicker drinks such as smoothies and nectars, and thickeners added to thin drinks, for people who choke on thin liquids like water. It offers this as something to try at home rather than something a speech pathologist has to set, so the answer is the more cautious of the two.
“If you are still choking, you can try thicker liquids like smoothies and nectars.”

Extra support with nutrition is common in ALS/MND, and it is usually offered early and gradually rather than only when things are difficult.
A dietitian may be suggested when:
- your weight is dropping, or you are finding it hard to eat enough
- swallowing or appetite changes are affecting what you can manage
- you would simply like advice on keeping your nutrition and energy up
In many clinics a dietitian is part of the team you see regularly, so you may not have to ask specially. You can always request input.
A feeding tube is one option your team may raise. It is not a last resort, and not something you have to accept. UK guidelines say the conversation should start at an early stage and be repeated at regular intervals as things change, taking into account swallowing, weight loss, breathing, the effort of eating and drinking and the risk of choking. So it is not only about how well you are swallowing or holding your weight. Breathing is part of the picture too, which is one reason the conversation can be relevant before eating itself feels like a problem. Teams often raise it earlier because a gastrostomy placed late carries more risk, including breathing complications and a higher risk of problems from the procedure itself. It does not have to mean stopping eating for pleasure, and it is a personal choice you can decline.
Because a feeding tube is a significant decision with its own considerations, it has a dedicated card that covers what it is, the benefits and burdens, timing, and that the choice stays yours. This card simply flags when the conversation tends to come up.
If your weight is falling or eating is a struggle, it is reasonable to ask your team whether a dietitian would help. When relevant, you can also ask about a conversation on feeding tubes. Earlier support usually means more options and less pressure.
Explained: what this word meansEvidence for this answer

Statement 1 of 3. Nutrition support in ALS/MND is normally offered early and revisited over time, rather than held back until eating is difficult.
Supports this. NICE MND guideline — NICE · Clinical guideline
The UK MND guideline starts nutrition support at diagnosis rather than at crisis point. Recommendation 1.11.1 has teams assess weight, diet, intake and swallowing at diagnosis and at every multidisciplinary team assessment and offer support as needed, and 1.11.6 has them discuss a gastrostomy at an early stage and then at regular intervals.

Statement 2 of 3. UK guidelines say the gastrostomy conversation should start at an early stage and be repeated at regular intervals as MND progresses, taking into account the person's ability to swallow, weight loss, respiratory function, the effort of feeding and drinking, and the risk of choking.
Supports this. NICE MND guideline — NICE · Clinical guideline
Recommendation 1.11.6 sets both the timing and the full list of things the gastrostomy conversation should take into account: ability to swallow, weight loss, respiratory function, the effort of feeding and drinking, and the risk of choking. It is a conversation to start at an early stage and repeat at regular intervals as MND progresses, not one held back until eating is difficult.
“Discuss gastrostomy at an early stage, and at regular intervals as MND progresses, taking into account the person's preferences and issues, such as ability to swallow, weight loss, respiratory function, effort of feeding and drinking and risk of choking.”
1.11.6Link checked August 2026
Statement 3 of 3. Teams raise a feeding tube early partly because placing one late carries more risk, including respiratory complications and a higher risk of complications from the procedure itself.
Supports this. NICE MND guideline — NICE · Clinical guideline
The UK MND guideline tells teams to explain both sides of the timing: the benefits of placing a gastrostomy early, and the risks of leaving it late, which it lists as including respiratory complications and a higher risk of complications from the procedure itself.
“Explain the benefits of early placement of a gastrostomy, and the possible risks of a late gastrostomy (for example, low critical body mass, respiratory complications, risk of dehydration, different methods of insertion, and a higher risk of mortality and procedural complications).”

A few questions can help you get nutrition support that fits you. A dietitian is usually the best person to answer most of them.
Where I am
- Is my weight steady, or has it changed?
- Am I getting enough nutrition and fluids?
Practical help
- What are the best ways for me to keep my energy and weight up?
- Are there easy, high-calorie foods or drinks you would suggest?
- Could nutritional supplement drinks help, and can you arrange them?
Joining things up
- How does this fit with my swallowing? Is what I am eating safe?
- What signs of weight loss or eating problems should I tell you about?
Looking ahead
- If eating by mouth gets harder, what other options are there, and when would we talk about them?
- Can I see a dietitian regularly?
It is fine to ask for written ideas, to involve whoever helps with cooking and meals, and to revisit these as things change. Keeping nutrition support practical and tailored helps you feel and function as well as possible.
