- Do: Spread carbs evenly across 3 meals+23 snacks.
- Dont: Rely on sugary drinks or candy for quick energy.
- Dont: Cut out wholegrain carbs completely theyre your glucosesteadying superheroes.
Core Diet Principles
Carbohydrate Control
Pick lowglycaemic index (LGI) carbs like quinoa, brown rice, oats, and legumes. Distribute them evenly: a modest serving at each meal and a small snack when you feel a dip. This keeps postmeal spikes under 140mg/dL for most women.
Protein & Healthy Fats
Lean meats, fish, tofu, beans, nuts, and seeds give you satiety without spiking glucose. A drizzle of olive oil or a few slices of avocado adds healthy fats that help your body absorb fatsoluble vitamins crucial for babys brain development.
Fruit Selection
Fruits are wonderful, but some pack a sugary punch. Heres a quick guide to what you can enjoy and what to keep on the maybe later list.
| Fruit | Portion | Glycaemic Impact |
|---|---|---|
| Berries (strawberries, blueberries) | 1 cup | Low |
| Apple (medium) | 1 | MediumLow |
| Orange | 1 medium | Medium |
| Kiwi | 2 | Low |
| Grapes | 1 cup | High |
| Mango | cup | High |
| Pineapple | cup | High |
| Dried fruit (raisins, dates) | cup | Very High |

Cultural Tweaks
If you love Indian flavours, swap white rice for brown basmati, use wholewheat chapati, add a side of dal, and finish with lowfat Greek yogurt raita. For a Western palate, think quinoa bowls with grilled turkey, roasted veg, and a sprinkle of feta.
PortionSize Calculator
Think of your plate as a pie chart: vegetables, complex carbs, lean protein. One cup of milk counts as one carb serving; a halfcup of cooked grains or starchy veg is another. This visual cue makes portion control feel less like math and more like art.
Snack Strategies
Pair protein with fibre to keep cravings at bay. Examples: apple slices with almond butter, a handful of mixed nuts and a cheese stick, or a small bowl of cottage cheese topped with berries. Prepack these combos in ziplock bags so youre never caught off guard.

Why Glucose Control Tightens
Hormones like human placental lactogen surge after week28, making your cells more insulinresistant. Thats why blood sugars that were once easy to manage may start wobbling as you near your due date.
Adjusting the Diet
