Food and shopping

Protein first. Then the carbohydrate.

Not “pair it”. Not “have some protein with it”. Protein goes in first.

The rule

Why it is that way round

Never eat a carbohydrate naked. Every carbohydrate gets a protein or fat partner. This is the single lever that reconciles standard nausea advice (plain, dry carbohydrate) with PCOS glucose stability.
Order matters, not just content. Fifteen to thirty grams of protein eaten before the carbohydrate lowers the glucose peak more than the same protein eaten alongside it. The effect is largest in people who are already insulin-resistant.
Reactive hypoglycaemia affects roughly half of lean young women with PCOS. Naked toast at eight is what produces the shakes and the spaciness at eleven. The same goes for naked crackers, naked fruit, naked cereal and, worst of all, juice.
Protein also reduces the nausea itself. Protein-predominant meals cut nausea and normalised the stomach’s electrical rhythm in first-trimester women; equal-calorie carbohydrate and fat meals did not. This is the rare intervention that fixes both problems with one action.

The numbers worth remembering

10–20 g	Protein per eating episode. Distribution is the game, not the daily total.
5–6 times	Eating episodes a day. Every two hours or so while awake.
Under 10 hours	The overnight fast. Bridge it with a bedtime protein snack.
+6 g a day	The whole UK protein increment for pregnancy. Total protein is rarely the problem.

Two moments worth more than the rest

Before bed. Around 10–15 g of protein with 15–30 g of carbohydrate, within an hour of sleeping. Greek yoghurt; cheese and oatcakes; milk and two biscuits.

Before standing up. Bedside carbohydrate plus a protein trace, eaten lying down. Then wait 15–20 minutes. Then sit. Then stand. The waiting is the intervention.

Pregnancy runs “accelerated starvation”: a long overnight fast drops glucose and raises ketones far faster than it would otherwise. Morning nausea and morning lightheadedness share that cause.

Where to go

Four pages, one vault file each

What do I pair this with?

Searchable

The carbohydrate-to-protein lookup, and the long list of proteins: grab-and-go, low-odour for bad days, vegetarian and vegan, two-minute assemblies, and the bedside kit.

Waitrose and M&S

Take this to the shop

The shopping list by aisle, the four label habits that do most of the work, and the things in a premium food hall that look safe and are not.

Absolutely avoid

Glanceable in an aisle

The hard no list, biggest risk first, one line each. Then the long list of things that are genuinely fine and get over-avoided.

When to eat

Timing and structure

The never-empty-stomach rule, the shape of the day, the get-out-of-bed protocol, and the harm-reduction ladder for days when only plain carbohydrate stays down.

Each of those four pages was written out of a single vault file, and every page names it: Protein pairingWaitrose and M&SAbsolutely avoidEating patterns.

The bare minimum that still counts

On the worst days the choice is not between a good pairing and a great one. It is between naked carbohydrate and any pairing at all. Butter on the toast. Milk in the tea. A glass of milk next to the biscuits. That is a win, and it is the whole point of the harm-reduction ladder.

If she cannot keep food or fluid down for 24 hours, none of this applies any more. Go to the red flags card. Dizziness or faintness together with pain or bleeding is a 999 call.
