Eat better

Nutrition for stable blood sugar, sustained energy and long-term health.

Our nutrition philosophy centres on stable blood sugar, Glycaemic Index (GI), Glycaemic Load (GL), quality protein, fibre and sustainable eating habits that support energy, recovery and healthy ageing.

Our nutrition philosophy

Better basics. Repeated consistently.

The best nutrition plan is one you can follow on ordinary weekdays, busy weekends, holidays and social occasions. We prioritise stable energy, blood-sugar-aware food choices, adequate protein, fibre, sensible portions and flexibility.

Different approaches can work. Our starting point is to understand how the type and amount of carbohydrate in a meal can affect blood sugar, appetite and energy. GI and GL are useful tools, but they work best alongside protein, fibre, healthy fats, portion awareness and an eating pattern you can sustain.

✓ Protein at each main meal
✓ Fibre-rich, lower-GI choices
✓ Balanced meals for steadier energy
✓ Glycaemic load and portion awareness
✓ Hydration and regular meal planning
✓ Sustainable progress over perfection
Starter guides

Understand the essentials first.

These guides form the foundation of the FitOver40 nutrition library, with a practical focus on blood sugar management, GI, GL, muscle maintenance and sustainable habits.

Protein After 40

Protein supports muscle maintenance, recovery and appetite control. Including it with carbohydrate foods can also make a meal more satisfying and help reduce sharp swings in hunger. Spread good-quality sources across your main meals rather than relying on one large serving.

  • Eggs, fish, lean meat and dairy
  • Beans, lentils and tofu
  • Convenient high-protein snacks

GI & Carbohydrates

Carbohydrates provide useful training fuel and fibre. Glycaemic Index describes how quickly a carbohydrate food raises blood glucose compared with a reference food. Quality, portion size and the rest of the meal all matter more than labelling carbohydrates as simply good or bad.

  • Choose minimally processed, fibre-rich sources
  • Use GI as a guide, not a pass-or-fail score
  • Match portions to activity, appetite and goals

Healthy Fats

Include sources such as olive oil, nuts, seeds, avocado and oily fish. Healthy fats can add flavour and satisfaction to meals and may slow digestion, but portions still matter because fats are energy dense.

  • Prioritise unsaturated fats
  • Use measured portions
  • Include oily fish regularly

Hydration

Hydration affects concentration, training quality, appetite awareness and general wellbeing. Build simple cues into your day rather than relying only on thirst, and remember that sugary drinks can add a large glycaemic load without much fullness.

  • Drink with each meal
  • Carry a reusable bottle
  • Increase intake around exercise

Sustainable Fat Loss

Fat loss requires a manageable energy deficit, but the plan should still support strength, protein intake, fibre, sleep and daily life. Meals that create steadier energy and better fullness can make that deficit easier to maintain.

  • Avoid crash diets
  • Track trends, not single days
  • Protect muscle with strength training

Eating Out and Weekends

A strong plan includes social meals. Use portion awareness, protein-first choices, vegetables where possible and sensible flexibility rather than an all-or-nothing mindset. One meal does not define the week.

  • Plan ahead when useful
  • Choose what matters most
  • Return to routine next meal

A practical starting point

Build a better plate.

This flexible template can be adjusted for appetite, goals, activity and personal preference. Combining protein, fibre-rich vegetables, controlled carbohydrate portions and healthy fats usually produces a lower glycaemic load than eating carbohydrate alone.

Meal planning made practical

Remove decisions before hunger makes them for you.

A simple weekly structure can improve consistency, reduce impulse choices and make lower-GI, balanced meals easier without requiring complicated batch cooking.

1Choose three balanced breakfastsRepeat reliable options such as eggs with wholegrain toast, Greek yoghurt with berries, or overnight oats with protein.
2Plan protein and vegetables firstSelect the main protein source and vegetables for lunch and dinner before adding a sensible carbohydrate portion.
3Prepare better convenience foodsKeep fruit, yoghurt, cooked protein, nuts, chopped vegetables and lower-GI staples ready.
4Leave room for real lifePlan social meals rather than treating them as failure, then return to your normal structure at the next meal.
Common questions

Nutrition FAQs

Do I need to count calories?

Not everyone does. Tracking can be useful for awareness, but some people make progress using consistent portions, balanced meals, lower-GL choices and regular progress monitoring.

Is keto suitable for men over 40?

It can be appropriate for some people, but it is not automatically superior. Food quality, medical circumstances, medication, training demands and sustainability should guide the choice. Anyone managing diabetes or blood-glucose-lowering medication should seek individual clinical guidance before making major carbohydrate changes.

How quickly should I lose weight?

Steady progress is generally easier to sustain and better supports training, stable energy and muscle retention than aggressive short-term loss.

Do I need supplements?

Supplements should fill a genuine need rather than replace food, sleep and training. Individual requirements may depend on diet, health status, medication and professional advice.

Core Nutrition Principles

Understanding Blood Sugar

Learn how carbohydrate is digested into glucose, why the body releases insulin, and how meal composition, activity, sleep and portion size can influence energy and appetite throughout the day.

Glycaemic Index (GI)

Use GI as one guide to compare carbohydrate foods. Lower-GI choices generally raise blood glucose more gradually, but GI does not account for serving size or the complete meal.

Glycaemic Load (GL)

Understand how carbohydrate quality and quantity work together. GL gives useful context because a modest portion of a higher-GI food may have a lower impact than a large portion.

Protein & Fibre

Build meals around protein and fibre to support muscle maintenance, digestive health and fullness. These foods also help create a more balanced response when eaten with carbohydrate.

Healthy Habits

Meal planning, hydration, regular movement and consistent routines beat short-term diets. A short walk after a meal can also be a useful everyday habit for many people.
