Eating During Pregnancy: When Your Body Changes the Rules

You are pregnant, and your body has started doing things without your permission. You are hungry at strange times. You crave foods you normally would not touch. Nausea makes the healthy meals you planned impossible. And the body that was yours is changing in ways that feel both miraculous and terrifying.

For someone with a straightforward relationship with food, pregnancy is a manageable disruption. For someone who has spent years trying to control their eating and their body, it can be a crisis.

A fictional example

The following is an illustrative example, not a real person’s story.

Zara is twelve weeks pregnant. She spent her twenties dieting and has a fragile peace with food. Now the hunger is enormous and unpredictable, the nausea makes salad impossible, and she is living on crackers and cheese. She looks at her changing body and the old thoughts arrive: too much, too big, out of control.

• What she thinks: “I’m eating terribly. I’m going to gain too much weight. I’m already failing my baby.”
• What she feels: anxiety about weight gain, guilt about food choices, fear of losing control of her body.
• What she does: tries to restrict, feels nauseous, eats crackers, feels guilty, restricts again.

Zara is not failing. She is doing what her body needs while fighting rules that no longer apply.

What the research shows

• Body dissatisfaction is common in pregnancy. A systematic review found that body dissatisfaction was common during pregnancy and that pre-pregnancy body image was a strong predictor of how women felt about their changing bodies [1]. A difficult relationship with your body before pregnancy does not pause for nine months.
• Eating disorders in pregnancy are underdiagnosed. Research found that eating disorders during pregnancy were more common than previously recognized, and that many women did not disclose their eating concerns to their healthcare providers [2].
• Cravings are normal and not fully understood. A review of pregnancy cravings found that they are extremely common, likely involve hormonal, sensory and cultural factors, and do not necessarily indicate nutritional deficiencies [3]. Following cravings in moderation is generally fine.
• Eating disorder history affects pregnancy eating. A study found that women with a history of anorexia nervosa had more difficulty with eating during pregnancy [4]. Past eating concerns do not disappear during pregnancy; they may intensify.

Questions to sit with

• Am I holding my pregnant body to the same standards as my non-pregnant body?
• What would I tell a friend who was anxious about eating during pregnancy?
• Can I let my body lead for a while, even if that feels uncomfortable?
• Am I eating enough for two people’s needs, or am I restricting because of old habits?

A small optional practice: the pregnancy permission

Write down three permissions for yourself:

1. I am allowed to eat when I am hungry, even if it is more than I used to eat.
2. I am allowed to eat what my body tolerates, even if it is crackers and cheese for a week.
3. I am allowed to gain weight. My body is supposed to change. This is not a failure.

Read them when the anxiety arrives. They are not affirmations. They are facts.

A worked example

Zara writes the permissions on a card and puts it on the fridge. When the guilt arrives about the crackers, she reads it. “I am allowed to eat what my body tolerates.” She stops trying to force salads that make her nauseous and eats what she can keep down.

She also tells her midwife about her history of dieting and food anxiety. The midwife refers her to a perinatal dietitian. Having someone who understands both pregnancy and eating concerns makes the nine months more manageable. She does not eat perfectly. She eats adequately. And that is enough.

When eating during pregnancy needs support. If you have a history of eating disorders, if pregnancy is triggering restriction, binge eating or purging, or if anxiety about food and weight is significantly affecting your wellbeing, please tell your midwife or doctor [5]. Perinatal eating disorders are treatable and your healthcare team needs to know. In the UK, Beat’s helpline for England is 0808 801 0677 [6]. In the US, call or text 988 if you are in crisis.
