Low‑Carb, High‑Life: Stay Under 100 g Carbs, Balance Protein & Feel Energised
Dropping to 100 g net carbs a day can cut fasting insulin by 20 % (BMJ 2024). Learn the sweet‑spot macros, smart food swaps and common pitfalls.
Hook
**One week at ≤ 100 g carbs/day improves glucose variability by 18 %—without the strictness of full keto.**
TL;DR
- Carb cap **50–130 g net/day** (10–26 % kcal)
- Fill the plate: non‑starchy veg + quality protein + healthy fats
- Watch hidden sugars in sauces & drinks, and add extra fibre
What counts as low‑carb?
Any diet providing **< 130 g net carbs** (total – fibre) or **< 26 % of calories**. Ketogenic is ≤ 25 g; low‑carb gives more flexibility for fruit, legumes and athletes.
Suggested macro split
| Macro | % kcal | g at 2000 kcal |
|-------|--------|--------------|
| Carbs | 15‑25 | 75‑125 |
| Protein | 25‑30 | 125‑150 |
| Fat | 45‑55 | 100‑120 |
Evidence‑backed benefits
1. **Better glycaemic control** – HbA1c ↓ 0.6 % in T2D (ADA 2024)
2. **Triglycerides ↓ 18 %** and HDL ↑ 6 %
3. **Satiety boost** from higher protein & fibre
Common pitfalls
- Replacing carbs with processed meats → ↑ saturated fat
- Under‑eating fibre (< 20 g) → constipation—keep veggies & chia
- ‘Low‑carb’ packaged snacks often hide maltitol → GI distress
Low‑carb staples vs sneaky carbs
| Choose freely | Limit/avoid |
|---------------|-------------|
| Leafy greens, broccoli, zucchini | Bread, pasta, rice |
| Eggs, fish, lean beef | Sweetened yogurt, granola |
| Berries (½ cup), avocado | Bananas, mango, dates |
| Nuts, seeds, olive oil | Fruit juice, soda, beer |
1‑day low‑carb menu (~90 g net carbs)
• **Breakfast**: Greek yogurt (unsweet) + ½ cup berries + chia (15 g NC)
• **Lunch**: Bun‑less turkey burger, cheddar, mixed‑green salad, olive‑oil vinaigrette (20 g NC)
• **Snack**: Celery sticks + almond butter (7 g NC)
• **Dinner**: Grilled salmon, cauliflower ‘rice’, sautéed spinach (18 g NC)
• **Dessert**: 25 g 85 % dark chocolate (10 g NC)
• **Total fibre** ≈ 28 g
Practical tips
- Track **net carbs = total – fibre** for veg and nuts.
- Swap rice with cauliflower or konjac noodles—saves 35 g carbs/cup.
- Aim for **two palm‑size protein servings** per meal to preserve muscle.
Myth vs fact
| Myth | Fact |
|------|------|
| “Low‑carb is zero‑carb.” | You can still eat fruit, beans and oats in moderation.
| “You must load on bacon.” | Unsaturated fats (olive, avocado, nuts) improve lipid profile.
| “Exercise performance tanks.” | Glycogen lasts for ≤ 60 min; strategic carb timing supports training.
Take‑home message
Keep carbs 50‑130 g, prioritise whole foods, hit fibre & protein targets—low‑carb can stabilise blood sugar and support weight management without keto extremes.
