BP’s Food for Thought
Zone Principles for the 10%
A carb reintroduction model for the metabolically healthy, hard-training woman who may simply function better with more fuel in the tank.
This is not “carbs are good” or “carbs are bad”. It is: what does this body run best on?
Six months of protein-first, lower-carb, higher-fat eating has done plenty right: improved body shape, improved gut comfort, strong metabolic numbers and better hormonal rhythm. That matters.
But if daily energy has stayed patchy for six months, we need to be honest. For a hard-training, metabolically healthy woman with excellent insulin tolerance, the answer may not be “go lower carb again”. The answer may be a smarter return of carbohydrates — placed well, portioned well, and earned through training.
Why some people function better with more carbs
1. Muscle glycogen matters
Higher-threshold training, intervals, strength work and faster efforts rely heavily on stored muscle carbohydrate. If glycogen is chronically low, the body may still perform — but often at a higher stress cost.
2. Female physiology is sensitive
Hard training plus low carb can sometimes increase perceived stress load. In some women this may show up as flat energy, lighter sleep, mood shifts or a sense of “running on reserve”.
3. Thyroid and nervous system tone
Long-term low carbohydrate intake can suit many people, but in some active bodies, carbohydrate availability supports thyroid conversion, body temperature, training drive and parasympathetic recovery.
4. Insulin tolerance changes the rules
If she is genuinely insulin tolerant — great HbA1c, waist, body composition, energy use and training output — she may handle carbs beautifully when they are whole-food based and timed around activity.
5. Gut health has a sweet spot
Too many carbs created GIT issues before. Too few may be affecting energy now. The target is the middle lane: enough fruit, root veg, rice, oats and yoghurt to fuel — without returning to digestive overload.
6. The brain likes glucose
The brain can use ketones, but some people simply think, work and feel better with a steady glucose supply. Especially when life load, work load and training load are all high.
Zone-style reintroduction: 40 / 30 / 30
A good starting model is close to the classic Zone idea: 40% carbohydrate, 30% protein, 30% fat. This is not a diet cage. It is a testing framework.
Protein first
Each meal starts with quality protein: eggs, fish, chicken, beef, lamb, Greek yoghurt, cottage cheese, tofu or legumes if tolerated.
Carbs with purpose
Carbs return mainly around training, breakfast and lunch — fruit, oats, rice, potato, pumpkin, sweet potato, quinoa, yoghurt and small sourdough if tolerated.
Fats stay in
Olive oil, avocado, nuts, seeds, butter, cream, oily fish and eggs remain. The goal is not low-fat. The goal is fuel balance.
How to bring carbs back without blowing the system up
Training days
- Carbs at breakfast or lunch.
- Carbs post-training to restore glycogen.
- Small simple carb option before threshold sessions if needed.
- Dinner can still be protein, veg and fat based.
Non-training days
- Lower carb, but not no-carb.
- Fruit, yoghurt, veg and small root veg serve if energy needs it.
- Avoid drifting back to bread, cereal, snacks and “health” bars.
- Let appetite and energy guide volume.
A week in the life — Zone-style, real-food, carb-supported
| Day | Breakfast | Lunch | Dinner | Training Fuel Thought |
|---|---|---|---|---|
| Monday | Greek yoghurt, berries, chia, walnuts, small oats serve. | Chicken salad bowl, olive oil, avocado, roast pumpkin. | Salmon, greens, zucchini, cream/lemon/herb sauce. | Post-training: banana or yoghurt if flat. |
| Tuesday | Eggs, spinach, mushrooms, small sourdough or potato hash. | Beef mince bowl, rice, cucumber, herbs, Greek yoghurt dressing. | Lamb, Greek salad, olives, feta, roasted veg. | Threshold day: ½ banana or dates pre-session if needed. |
| Wednesday | Protein smoothie: milk/kefir, berries, protein, creatine, cinnamon. | Tuna, potato, boiled egg, greens, olive oil dressing. | Chicken thigh curry with veg and small rice serve. | Post-training carbs placed here, not random night grazing. |
| Thursday | Cottage cheese, fruit, nuts, cinnamon, honey drizzle. | Turkey or chicken wrap/bowl with salad and avocado. | Steak, broccolini, mushrooms, butter, sweet potato. | If energy is strong, keep carbs modest. |
| Friday | Omelette with feta, herbs, tomato, small fruit serve. | Salmon rice bowl with greens, sesame, avocado. | Prawns or white fish, veg, olive oil, potato or pumpkin. | Carbs support weekend session readiness. |
| Saturday | Pre-training: banana/coffee. Post: eggs, yoghurt, berries, oats. | Chicken, quinoa, roast veg, tahini/lemon dressing. | Slow-cooked beef, veg, cauliflower mash, optional potato. | Bigger training day = bigger carb permission. |
| Sunday | Eggs, avocado, tomato, mushrooms, fruit if desired. | Leftover protein bowl with rice/potato if energy needs it. | Protein-first family meal, lots of veg, fats kept in. | Review energy, sleep, gut and training quality. |
Natural flavour upgrades
Creamy
Greek yoghurt, sour cream, cream, tahini, avocado, feta, cottage cheese, lemon and herbs.
Spice
Cumin, paprika, turmeric, chilli, cinnamon, ginger, garlic, pepper, curry blends and rosemary.
Acid + herbs
Lemon, lime, vinegar, mustard, parsley, basil, coriander, mint and dill.
Why you should maintain creatine
Creatine is not just a gym-bro supplement. For a hard-training woman, it can support repeated high-intensity output, strength training quality, muscle preservation, recovery and possibly cognitive energy under load.
In this case, creatine pairs well with a carb reintroduction phase because improved glycogen availability plus creatine-supported phosphocreatine stores may help restore that “snap” in training.
Track the right things
The win is not just the scale or body shape. The real question is: does she feel better, train better, sleep better and stay metabolically excellent?
- Morning energy and motivation
- Training sharpness and recovery
- Sleep depth and consistency
- Hormonal rhythm and mood balance
- Gut comfort and digestion
- Appetite control and cravings
- Body composition and muscle fullness
- Whether the “spark” returns to daily life
If energy improves while metabolic markers remain excellent, this may simply confirm that her physiology performs best with a moderate, strategic carbohydrate intake — not a chronically low one.
The mission
We are not returning to a high-carb diet. We are returning to carb intelligence.
For this woman, the best-fitting nutrition may sit between the two worlds: protein-first, whole-food, fat-supported eating — with enough clean carbohydrate to match her physiology, training output, nervous system load and life demands.
