IELTS Vocabulary for Health and Fitness: Collocations for Band 7+

Health, fitness and lifestyle come up constantly in IELTS — in Speaking Part 1 ("Do you have a healthy lifestyle?"), in Part 3 discussions about healthcare, and in Writing Task 2 essays on government spending, junk food or exercise. Because the topic is so predictable, examiners have heard every memorised phrase a hundred times. The candidates who score well are not the ones with the longest word lists; they are the ones who use accurate, natural collocations in the right place. This guide gives you the health vocabulary that actually moves your band, and shows you how to use it.

Why This Vocabulary Matters

Lexical Resource is one of the four equally weighted marking criteria in both Speaking and Writing, so it accounts for roughly a quarter of your score in each. The descriptors do not reward rare or "advanced" words for their own sake — they reward range, precision and natural collocation. A Band 5 candidate says "do exercise"; a Band 7 candidate says "take up regular exercise" or "lead an active lifestyle." Same idea, but the second sounds like a real English speaker rather than a translated word list.

Learn Collocations, Not Single Words

English pairs certain words together in ways that cannot be guessed from grammar rules. You gain weight but put on weight; you follow a diet, not "do" a diet. Memorising these chunks is what makes your English sound fluent under pressure. Group them by sub-topic so you can pull the right set when a question lands.

Diet and Nutrition

• a balanced diet — eating a sensible mix of foods
• cut down on / cut back on sugar, salt, processed food
• fresh produce — fruit and vegetables
• fizzy drinks and junk food — high in sugar and fat
• nutritional value — how healthy a food is
• overeat / skip meals

Exercise and Fitness

• lead an active lifestyle vs a sedentary lifestyle (sitting most of the day)
• take up a sport; work out at the gym; stay in shape / keep fit
• build up stamina and muscle
• burn calories; get out of breath

Mental Wellbeing

• mental wellbeing / mental health
• cope with stress; feel under pressure; burn out
• unwind / recharge your batteries after work
• a good work-life balance

Healthcare and Society (for Task 2)

• preventive healthcare — stopping illness before it starts
• public healthcare vs private healthcare; free at the point of use
• put a strain on the health system; raise awareness of a health issue
• life expectancy; a sedentary population; obesity rates

Model Sentences You Can Adapt

Vocabulary only earns marks when it sits inside a natural sentence. Notice how the collocations below do the work without any "big" words:

• Speaking Part 1: "I try to keep fit by cycling to work, and I've cut back on fizzy drinks recently — I just feel more energetic."
• Speaking Part 3: "I think governments should invest more in preventive healthcare, because encouraging people to lead active lifestyles is far cheaper than treating illness later on."
• Writing Task 2: "As more people adopt a sedentary lifestyle and rely on processed food, obesity rates have risen, placing a growing strain on public health systems."

Each of these would strengthen the Lexical Resource band without a single memorised idiom sounding forced. If you want to see how your own essay scores on this criterion, paste it into our free AI IELTS essay checker for a criterion-by-criterion estimate.

Common Mistakes to Avoid

1. Forcing memorised idioms. Dropping in "an apple a day keeps the doctor away" to prove you know an idiom sounds unnatural and can lower your score. Use everyday collocations naturally instead.
2. Wrong word form. "Healthy" (adjective) and "health" (noun) are mixed up constantly — "a health lifestyle" is a common slip that costs accuracy marks.
3. Overusing one word. Repeating "healthy" ten times signals a narrow range. Vary it: "nutritious," "good for you," "beneficial," "in good shape."
4. Too informal in Writing. "Junk food" and "fizzy drinks" are fine, but avoid slang; keep an academic register in Task 2.

How to Practise

Do not try to memorise all of these at once. Pick one sub-topic, write three or four of your own sentences using its collocations, and say them aloud until they feel automatic. Then recycle them across question types — a diet collocation used in Speaking Part 1 can reappear in a Task 2 essay. Build the same habit for other frequent themes, such as the language in our guide to IELTS vocabulary for the environment, and rehearse your answers on the IELTS Speaking questions bank. Precise, natural collocations used with confidence are exactly what separates a Band 6 from a Band 7 in Lexical Resource.
