That 3pm crash isn't just "getting older"
Hey friend,
By now you’ve started noticing patterns in your cycle and your symptoms — beautiful work, by the way. This week, let’s add one more layer: food and mood.
If you’ve noticed that some days you feel calm, clear, and steady, and other days you’re white-knuckling your way through a 3pm energy crash with a desperate craving for something sweet... I want you to know this isn’t a willpower problem. There’s real, documented physiology behind it.
The estrogen–blood sugar connection
Research has consistently shown that estrogens play a protective role in maintaining insulin sensitivity, and reviews note that estrogen optimizes insulin activity by enhancing glucose uptake and reducing insulin resistance — which is part of why premenopausal women tend to have greater insulin sensitivity than men of the same age.
As hormones shift in perimenopause, this protection becomes less stable. A large community-based cohort study tracking women through the menopause transition found that diabetes risk increased during the premenopausal-to-perimenopausal years, alongside measurable declines in insulin sensitivity and pancreatic β-cell function over time. Mechanistic research adds more detail: one population study found that estradiol levels were positively associated with both fasting glucose and HbA1c (a marker of average blood sugar over time), particularly in women approaching or past menopause. nih
Even within a single cycle, estrogen and glucose move together — one continuous glucose monitoring study found that blood glucose and food cravings shifted across menstrual cycle phases, tracking with the fact that estrogen is typically lowest during menstruation and highest around ovulation. As cycles become erratic in perimenopause, it makes sense that this steady rhythm gets disrupted too. PubMed Central
It’s not just blood sugar — cravings are real and documented
If you’ve noticed stronger cravings lately, you’re not imagining it. Research on the menstrual cycle has found that women experience increased cravings for sweets and carbohydrate-rich foods, along with more frequent emotional eating, during hormonally shifting phases of the cycle — and women generally prefer high-carbohydrate, sweet foods during the phases when progesterone is more dominant. One proposed mechanism is that carbohydrate-rich foods increase the availability of tryptophan, a precursor to serotonin, which may temporarily improve mood and emotional regulation — which is a pretty compassionate explanation for why we reach for the bread basket on a hard day. nih
Why tracking the two together helps
This is where it gets practical and genuinely useful: connecting what you eat with how you feel afterward — energy, mood, cravings, focus — turns vague “I feel off” days into a pattern you can actually see. Pair this with the cycle and symptom tracking you’ve already started. Over a week or two, you’ll likely start noticing things like: a slump that follows a low-protein lunch, or irritability creeping in after skipped meals.
What to jot down
What you ate (roughly — no perfectionism needed)
Mood and energy 1–2 hours later
Any cravings, and what they were for
Where you are in your cycle
A both/and note
None of this means cutting out carbs or fearing sugar, that’s not what the research supports, and restriction often backfires. It simply means understanding your own patterns so you can work with your body instead of feeling blindsided by it. If you’re managing diabetes risk, PCOS, or are on any related medications, definitely loop your provider in; blood sugar patterns in perimenopause are worth a real conversation with them, not just a lifestyle tweak.
This week’s gentle action step: For 5–7 days, jot down meals alongside mood and energy an hour or two later. Look for your pattern, not a generic rule.
You’re not imagining the crash. You finally have language ,and now data, for it.
With you in this,
Chantal

Your Food and Mood Protocol: What to Do Once You Start Seeing the Patterns
You’ve been tracking. You’re starting to see the connections. Now let’s turn that data into a system , one that works with your hormones instead of against them, keeps your blood sugar steady through the day, and stops the crash before it starts.
This is the exact framework I use with clients at every stage — perimenopause, the menopausal transition, and postmenopause. The blood sugar picture looks slightly different at each stage (more erratic and unpredictable in peri, more consistently flat but stubborn in post), but the protocol is the same.
THE PROTOCOL
Step 1: Identify your personal crash window
Before you change anything, look back at your tracking from this week. Ask yourself:
What time of day does my energy reliably drop?
What did I eat in the 2–3 hours before that crash?
Was there a meal I skipped, or a gap longer than 4–5 hours between eating?
Did a craving follow the crash — and what was it for?
Most women have a predictable crash window — usually mid-morning or mid-afternoon — that directly traces back to what happened at the meal before. Once you find yours, you have a target. Everything in this protocol is aimed at that window.
Step 2: Build every meal around this sequence
This is the single most impactful structural change you can make, and it costs nothing. Research from glucose scientist Jessie Inchauspe shows that eating food in this order at every meal reduces your post-meal glucose spike by up to 75% — without changing what you eat, only the order:
Vegetables first — eat all the vegetables on your plate before anything else
Protein and fat second — your legumes, tofu, tempeh, nuts, seeds, avocado
Carbohydrates and fruit last — whole grains, starchy vegetables, fruit
The fibre in vegetables forms a kind of mesh in your digestive tract that slows the absorption of glucose from the carbohydrates that follow. Your blood sugar rises more gently, your insulin response is smaller, and you stay steadier for longer. Do this at every meal this week and notice what happens to your crash window.
Step 3: Observe how you react to carbohydrates alone
Every carbohydrate source you eat will impact you differently. If you notice a persistent (over 2 hours) rise in glucose from your meal, or track your metabolic flexibility and you don’t see a switch between fat and carb burn and back, then maybe it is time to reconsider.. what carbs are you having? And should you have carbs with protein or fat alongside it? This is buffering. Here’s what it looks like in practice:
Fruit on its own → spike and crash? Try fruit with almond butter or a handful of pumpkin seeds → observe if you have a slow and steady rise
A grain alone → spike and crash? Maybe add avocado and notice within 2 hours → sustained energy
A handful of dates as a snack → spike and crash? Dates with walnut halves → manageable perhaps?
The combination of fibre, protein, and fat slows gastric emptying and maybe you need this to feel more satiated long term, meaning glucose enters your bloodstream more slowly and your body has time to manage it without the emergency insulin surge that causes the crash. This is not metabolic reality for all women, but this is why we pay attention.
Step 4: The strategic 3pm snack — non-negotiable
If your crash window is mid-afternoon, the solution is not willpower at 3pm. It’s what you eat at lunch, and whether you have a strategic snack in place before the crash hits.
Do not wait until you’re desperate and reaching for whatever is closest. Instead, eat a small, intentional snack at around 3pm, before the crash arrives, built around protein and fat:
1 tablespoons of almond or peanut butter with celery sticks
Hummus with raw vegetables
Edamame with a pinch of sea salt
A small tbsp of mixed nuts and a couple of squares of dark chocolate (85%+)
The goal is to keep blood sugar stable through the afternoon so you arrive at dinner calm and in control, not ravenous and reactive.
Step 5: Manage your morning cortisol window
Cortisol naturally peaks in the first 30–45 minutes after waking — this is normal and healthy. What’s not helpful is adding caffeine into that window, especially if you are stressed already. It amplifies the cortisol spike and raises blood sugar before you’ve eaten a single thing.
This matters more in perimenopause and postmenopause because cortisol and estrogen are in constant conversation. When cortisol is chronically elevated, which chronic stress, poor sleep, and blood sugar swings all contribute to, it further suppresses the already-declining estrogen and progesterone. Managing your morning cortisol is hormonal support, not just a coffee habit tweak.
The practice:
Delay your first coffee by 60–90 minutes after waking
Move your body for 10 minutes within 30 min of waking - use that glucose from the morning cortisol.
Eat breakfast before or alongside your first coffee
Make breakfast protein and fiber forward, aim for at least 20g of protein at your first meal. the beauty of plants is that you never skip the fiber even with the protein.
Step 6: Move after meals, even for 10 minutes
A 10-minute walk after eating is one of the most evidence-backed blood sugar interventions that exists, and you don’t need a gym, equipment, or a plan. Movement after eating causes your muscles to take up glucose directly, bypassing the need for insulin to do the job. This measurably flattens the post-meal glucose curve.
If you cannot walk, stand up and do light movement, washing up, tidying, anything that keeps you on your feet for the first 20 minutes after eating. Sitting still immediately after a meal is the worst thing you can do for post-meal glucose.
Step 7: Use your tracking to test, not to judge
Now that you have the protocol, use your food and mood diary as a testing tool. For each change you make, track:
What I changed
How my energy felt 2 hours later
Whether the crash came, and how severe
My mood score that afternoon
You are running a personal experiment with a sample size of one, yourself. Your data is more relevant to you than any general study, because it reflects your hormones, your body, and your life. Within 5–7 days of consistent tracking alongside these changes, most women start to see a clear picture of what works for them specifically.
What to expect and when:
Most women notice the afternoon crash easing within 3–5 days of eating in sequence and pairing carbohydrates with protein and fat. The morning clarity usually improves within a week of delaying coffee and eating protein at breakfast. The cravings, the desperate, urgent ones, typically reduce significantly within 10–14 days as blood sugar stabilises. They don’t disappear entirely, and they don’t need to. But they stop running the show.
⚡ THIS WEEK’S ACTION STEP
Tonight, decide what you are having for breakfast tomorrow. Make sure it includes 20g of protein, overnight oats with ground flaxseed, hemp seeds, and chia seeds, or a tofu scramble with black beans and vegetables. Set your coffee next to it, not before it. Eat first, then coffee. Just that one change, tomorrow morning. Track how you feel at 10am and compare it to your usual. That single data point is the beginning of your pattern.
🔬 SCIENCE SPOTLIGHT
A 2022 study found that the order in which food is consumed at a meal significantly affects post-meal glucose and insulin responses — independently of the total calories or macronutrients consumed. Participants who ate vegetables and protein before carbohydrates showed dramatically lower glucose spikes and smaller insulin surges than those who ate carbohydrates first, even when the meals were nutritionally identical.
This is particularly significant in perimenopause and postmenopause because of what happens downstream from every glucose spike: an insulin surge, followed by a cortisol response, followed by a drop that your brain reads as a genuine emergency, triggering cravings, irritability, and fatigue. Every spike adds to the cumulative inflammatory load, and estrogen’s natural buffering of that process is no longer as reliable as it once was.
The researchers noted the effect was consistent across body types, ages, and metabolic starting points, meaning this works regardless of where you’re starting from.
Takeaway: You don’t have to change what you eat to change how your blood sugar behaves. Start with the order, and build from there.
💛 CHANTAL’S CLIENT INSIGHT
One of my clients came to me at 47, in perimenopause, describing what she called “the 3pm monster.” Every afternoon, without fail, she became irritable, unfocused, and desperate for something sweet. She’d been managing it with willpower and feeling like she was failing every day she gave in.
When we looked at her food diary, the pattern was immediate: a light lunch at 12:30, usually a salad with very little protein, and then nothing until dinner at 7pm. A six-hour gap, a low-protein anchor, no afternoon snack. Her 3pm crash wasn’t a character flaw. It was a blood sugar event that had been scheduled into her day by her meal structure.
We made three changes: we added a protein source to her lunch (a tin of chickpeas or half a block of tofu), introduced a 3pm snack of almond butter and apple, and she started walking for ten minutes after lunch. That was it. No calorie counting, no restriction, nothing removed.
Within five days the 3pm monster was significantly quieter. Within two weeks it was essentially gone. She messaged me to say: “I thought I just had no self control in the afternoons. It turns out I was just genuinely running on empty.”
Your cravings are not a character flaw. They are feedback. And now you have the tools to answer them properly.
