How skipping meals affects your hormones, energy, and mood during a busy season

As a nutrition coach who has worked with Jewish women for many years, one topic I rarely get enough time to speak about is hormones.

Every woman I work with is in a different stage of life. Fertility, perimenopause, menopause. We are all somewhere on that journey. But no matter where you are, the way you eat makes a direct difference to how you feel, how you sleep, and how you cope with everything life is asking of you right now.

And as the busy season builds, whether it is Pesach preparations, simchas, work, family, or just the constant challenge of being a busy Jewish woman in today's world, the first thing that tends to go is the meal.

I want to show you exactly what that costs you.

Your Body Runs on a Clock

Everything your body does follows a daily rhythm. Your hormones, your digestion, your energy, all of it runs on a 24-hour cycle called the circadian rhythm.

In the morning, usually between 6 and 9am, cortisol rises naturally. That is actually helpful. It is what wakes you up and gives you focus for the day ahead. But if you go too long without eating, cortisol keeps climbing and your blood sugar starts to drop.

For most women, eating something within 90 minutes to two hours of waking helps keep blood sugar stable. Some women are hungry immediately. Some are not. Your body gets used to its rhythm, and the goal is to understand how yours responds.

In our group sessions, I ask women to share what their mornings look like. What comes up again and again is how much the snack between breakfast and lunch matters. One woman shared:

That is awareness. That is your body telling you something important.

In the evening, melatonin begins to rise and your body starts preparing for sleep. When we eat a very heavy or late meal, the body has to work hard when it really wants to rest. That affects sleep quality, digestion, and how you feel the next morning.

As Pesach preparations get more intense and the late nights stretch longer, keeping to your meal rhythm as much as possible is one of the most powerful things you can do right now.

Your body is incredibly intelligent. It has a rhythm. When you eat with it, everything works better.

What Happens to Progesterone and Cortisol

Two hormones are most directly affected by how you eat. Let me explain both.

Progesterone is the calming hormone. When it is where it should be, you feel steady. Sleep is good. Mood is even. You can handle things, manage things, show up.

When it drops, and it drops fast when we are not eating well or sleeping enough, everything feels harder. The anxiety that arrives seemingly from nowhere. Sleep does not refresh you. The feeling of being overwhelmed by the exact same to-do list you managed fine last week.

Here is the direct connection.

When you skip meals or go too long without eating, blood sugar drops. The body releases cortisol to compensate. And elevated cortisol directly suppresses progesterone production.

So skipping lunch on a heavy cleaning day is not just a 3pm headache. It means less progesterone that evening, worse sleep, higher anxiety, and less resilience the next morning. The chain is that short.

Cortisol gets a bad reputation, but we need it. Think of it as your body's emergency fuel. It wakes you up in the morning and keeps you going when things get demanding. In small doses, at the right times, it is working for you.

The problem is when cortisol stays high all day. That happens when meals are skipped, sleep is poor, and stress keeps building. Your body stays in emergency mode for hours at a time, and over days and weeks, you start to feel the effects.

Chronically elevated cortisol looks like weight gain around the middle, constant tiredness even after sleep, brain fog in the afternoons, and that very specific feeling of being wired and exhausted at the same time. Many women I work with recognise this immediately.

One woman laughed when I mentioned sleep, because she is mid-simcha season, weddings, bar mitzvahs, Pesach all at once. She said:

Yes. And that koach is cortisol doing its job. It is real. It carries us through. But the question I always ask is, at what expense? And how do you want to arrive at the seder table?

Feed yourself through it and you manage. Skip meals through it and your cortisol does the rest.

What Really Happens When You Skip a Meal

Let me walk you through a typical pre-Pesach day.

You wake up and want to get straight into the kitchen and start working through your list. Maybe you have your lemon water, but breakfast feels like it can wait.

The first couple of hours actually feel fine. You are focused, productive, getting things done. Your body is using its stored energy and you do not feel hungry yet.

Then a few more hours pass.

Your blood sugar starts dropping. Your body releases cortisol to keep you going. You become a little short. Someone asks you something simple and you snap. You feel scattered and unable to make a decision.

That is not a personality problem. That is your blood sugar sending you signals.

Later in the day, your brain starts asking for fast fuel. The cravings kick in. The takeout for the kids suddenly looks very appealing. Whatever is quick and nearby. That is your body doing exactly what it is supposed to do when it has been running without enough fuel for too long.

When you finally sit down to eat, you are very hungry. You eat fast and more than you planned. Your blood sugar shoots up and then drops again a couple of hours later. Sleep that night is restless. And the next morning, the whole cycle starts again.

Once you see this pattern, you cannot unsee it. And that awareness is exactly where change begins.

Protein: The Anchor Your Hormones Need

One of the most powerful things you can give your body during a busy season is consistent protein at every meal. And honestly, this applies all year. When are we not busy?

Protein stabilises blood sugar. When blood sugar is stable, energy is steadier, cravings are lower, and your hormones can do their work properly. Protein also provides the building blocks your body uses to make those hormones in the first place. And it keeps you full for longer, so you are far less likely to crash at 4pm.

Aim for 25 to 30 grams of protein at each meal. You do not need to count every gram. The simplest approach is to build your meal around a protein source and work outward from there.

A tip worth knowing: combining different protein sources in one meal, for example eggs with chickpeas, or yogurt with chia seeds, gives your body a broader range of amino acids and often makes for a more satisfying and complete meal overall.

In the busy weeks before Pesach, excellent options are all around you. The chart below will help you see exactly what your portions are giving you.

Movement That Supports Your Hormones

What if you started moving for muscle, and not for weight loss?

Because as we get older, from around age 35, we begin to lose muscle. And muscle is not just about how we look. It is metabolically active tissue. The more functional muscle you carry, the more efficiently your body manages blood sugar, which means less cortisol demand, more stable energy, and better mood throughout the day.

Strength training, whether that is lifting weights, using resistance bands, or simple bodyweight exercises at home, sends a direct signal to your body that muscle needs to be preserved. Without that signal, the body slowly breaks it down.

Here is what is important to understand about Pesach prep. The schlepping, the cleaning, the hours on your feet, that is physical exhaustion. It drains you. It does not build muscle. Even 20 minutes of intentional movement, squats, lunges, two bottles of water used as weights, has a completely different effect on your hormonal chemistry. You do not need a gym. You can do it at home. The goal is purposeful, consistent movement for your muscles, not the hard physical labour that simply wears you out.

Five Things I Recommend

Everything we have spoken about means nothing if, on the day you are on your knees scrubbing the oven, you have not eaten since the night before.

So let us make it practical. Pick one of these five things. Start there.

1. Eat within 90 minutes of waking

Cortisol is already rising when you open your eyes. Eating within 90 minutes anchors your blood sugar before it has a chance to climb further. If you are not hungry for a full meal, a small snack with protein counts. Something is always better than nothing.

2. Front-load protein at breakfast

Aim for 25 to 30 grams before the day begins. A smoothie with two tablespoons of chia seeds, or two eggs and avocado, are great options. This first meal sets the tone for your blood sugar for the entire morning.

3. Protect lunch, even on the heavy cleaning days

Set an alarm if you need to. Step away for ten minutes. A hard-boiled egg, some cottage cheese, a handful of chickpeas with olive oil. The to-do list will still be there when you get back. You will work better for the rest of the afternoon because you stopped.

4. Plan your afternoon snack

3pm to 4pm is when blood sugar naturally dips. Before Pesach, this is also when the stress of the day has fully accumulated. Have something ready. Fruit and nuts, yogurt, a boiled egg. Do not arrive at the dinner table running on empty.

5. Protect your sleep as much as you can

One poor night raises cortisol and drops progesterone within 24 hours. I know that for many of you, in simcha season, with little ones, with everything happening in Israel, this is the hardest one on the list. I am not here to add guilt. Do what you can. Even one earlier night this week will make a difference your body will feel.

A Note on All of This

We are not eating well just to lose weight. We are not doing this only to feel good, though that matters enormously.

There is so much happening inside the body with every meal we eat and every meal we skip.

When you understand the why, the hormones, the cortisol, the progesterone, the blood sugar, it shifts something.

You are doing this for something deeper. For being healthy. For being vibrant. For showing up fully for your family, your home, and your avodas Hashem.

You cannot pour from an empty cup. And you cannot run a Pesach on an empty tank.

Fuel yourself like the person this chag depends on. Because you are that person.
