Lesson 1: Introduction: macronutrients

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about macronutrients. Then check against the key terms: key terms from macronutrients. Use a mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: key terms from macronutrients.
If stuck: Re-read the revision notes (link above), then break the content into smaller steps.
Extension: See the Stretch & Challenge ideas in Lesson 4.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: macronutrients. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Food Preparation and Nutrition because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.
First Look

Start with the revision notes summary, then attempt: explain the key ideas of macronutrients

Your student states one thing they learned and one question they still have about macronutrients.

Lesson 2: Core Concepts: macronutrients

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on macronutrients. Check them against the notes below.

Main Content (35 minutes)

Key Fact: Carbohydrates are the body's main source of energy. They are divided into sugars (simple, quick-release) and starches (complex, slow-release). Excess glucose is stored as glycogen in the liver and muscles, or converted to fat.
Key Fact: Proteins are essential for growth, repair, and maintenance of body tissues. They are made up of amino acids — there are 20 amino acids, 9 of which are essential (cannot be synthesised by the body and must come from food).
Key Fact: High biological value (HBV) proteins contain all 9 essential amino acids — found in animal sources (meat, fish, eggs, dairy) and soya. Low biological value (LBV) proteins lack one or more essential amino acids — found in plant sources (cereals, pulses, nuts).
Key Fact: Complementary proteins: combining LBV protein sources to provide all essential amino acids — e.g. rice and beans, hummus and pitta, toast and baked beans.
Key Fact: Fats (lipids) provide concentrated energy (9 kcal/g vs 4 kcal/g for carbs and protein), insulate the body, protect organs, carry fat-soluble vitamins (A, D, E, K), and provide essential fatty acids.
Key Fact: Saturated fats (mainly animal sources — butter, lard, cheese) are solid at room temperature and raise LDL cholesterol. Unsaturated fats (plant and fish sources — olive oil, oily fish) are liquid and can help lower cholesterol.

Explain Back

Your student teaches the key points back to you without looking. Fill any gaps immediately.

Lesson 3: Application: macronutrients

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Recall the key terms: key terms from macronutrients. Define each in one sentence.

Main Content (35 minutes)

Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.

Work through the practice questions on the revision notes page for this topic.

Error Review

Review any questions answered incorrectly. Identify whether the error was knowledge, method, or reading the question.

Duration: 50 minutes

Starter Activity (5 minutes)

Command Words

Review what these command words require: state (one point), describe (say what happens), explain (say why), compare (both sides), evaluate (judgement).

Extended Answer

Extended question: Full-Mark Response Evaluate the role of macronutrients in maintaining a healthy diet. [12 marks] <div class="

Macronutrients — carbohydrates, proteins, and fats — each play essential roles in maintaining health, and balance between them is crucial. Carbohydrates provide the body's primary energy source. Glucose from carbohydrate digestion fuels the brain and muscles. Complex carbohydrates (wholegrains, pulses) also provide dietary fibre, essential for digestive health and reducing risk of bowel cancer and type 2 diabetes. Current UK guidelines recommend carbohydrates provide about 50% of dietary energy. Proteins are vital for growth, repair, and maintenance of body tissues. HBV proteins from animal sources provide all essential amino acids, while LBV plant proteins can be combined to achieve the same effect. Protein deficiency causes kwashiorkor and marasmus, though these are rare in developed countries. Fats provide concentrated energy and carry fat-soluble vitamins (A, D, E, K). However, the type of fat matters significantly: unsaturated fats (olive oil, oily fish) reduce cardiovascular risk, while excess saturated fats (butter, fatty meat) raise LDL cholesterol and increase heart disease risk. The balance between macronutrients is key. The Eatwell Guide recommends roughly 50% energy fro

Exam Tips: Always give at least two specific food sources for each nutrient | Link nutrient functions to health — not just 'energy' but 'provides glucose for brain function' | Use the correct terminology: HBV/LBV, essential/non-essential amino acids, saturated/unsaturated
Common Errors: ✗ All fats are bad for you. ✓ Fats are essential — they provide energy, carry fat-soluble vitamins, and provide essential fatty acids. The type of fat matters: unsaturated fats are beneficial while excess saturated and trans fats increase health risks. ✗ Plant proteins are inferior to animal proteins. ✓ Plant proteins are LBV (missing some essential amino acids) but can be combined to form complementary proteins that provide all essential amino acids. A varied plant-based diet can meet protein needs. ✗ Carbohydrates make you fat. ✓ Excess calories from any source cause weight gain. Carbohydrates are the body's preferred energy source. Complex carbohydrates (wholegrains) are particularly bene
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how macronutrients connects to another Food Preparation and Nutrition topic you have studied
  • Real-world: research one real-world use or example of macronutrients
  • Critical: "What are the limitations of the models used in macronutrients?"
