Why most women just can’t say no to dessert: The science behind food cravings

Sugar cravings are a common experience for everyone, but research consistently shows that women are more likely than men to crave sweet foods — and often experience these cravings more intensely.

This difference goes beyond simple preference or willpower; it stems from a complex interaction of biology, brain chemistry, hormonal fluctuations, and social factors. Women's bodies are naturally wired to experience sugar cravings more frequently and intensely, influenced by hormonal changes, emotional well-being, and stress levels.While cravings are a natural part of life for both genders, understanding why women have a stronger inclination toward sweets requires examining both what drives women’s cravings and why men's experiences differ. Pariksha Rao, Director – Nutrition & Medical Affairs at The Good Bug, sheds light on the reasons behind this difference.

The science behind women’s sugar cravings

Hormonal fluctuations

Women’s sex hormones-estrogen and progesterone-fluctuate throughout the menstrual cycle, pregnancy, and menopause. These hormonal shifts directly impact mood, appetite, and the brain’s reward system. For example, serotonin, a neurotransmitter that regulates mood and appetite, tends to be lower in women, especially during certain phases of the menstrual cycle.

When serotonin drops, eating sugary or carbohydrate-rich foods can temporarily boost its levels, making sweets especially appealing during times of low mood or stress.

Stress and emotional eating

Research shows women are more likely than men to eat in response to stress or emotional upset. Stress increases levels of the hormone ghrelin (which stimulates appetite) and can lower leptin (which suppresses appetite), particularly in women. This hormonal response, combined with cultural pressures and a higher prevalence of emotional eating, means women are more likely to reach for sugary foods as a coping mechanism.

Gut microbiome and sugar cravings

Our gut microbiome, composed of trillions of bacteria, profoundly influences our cravings by signaling the brain. An important subset of the gut microbiome, known as the estrobolome, is responsible for metabolizing estrogen. Women’s hormonal cycles can alter their gut bacteria balance, particularly impacting the estrobolome and leading to fluctuations in estrogen levels. These estrogen fluctuations can heighten susceptibility to sugar cravings at particular times, such as before menstruation.

Additionally, a diet high in sugar encourages the growth of sugar-dependent bacteria, creating a reinforcing cycle of cravings.

Ovarian hormones and energy needs

Before menstruation, women’s bodies biologically prepare for a potential pregnancy by increasing energy storage needs. This preparation often manifests as cravings for calorie-rich, sugary foods, providing a readily available source of energy.

How men’s sugar cravings differ

While both genders experience food cravings, men generally exhibit differences in intensity, frequency, and type:

Hormonal stability

Men typically experience more stable hormone levels, particularly testosterone, compared to the cyclical fluctuations of estrogen and progesterone in women.

This hormonal stability contributes to fewer hormonally driven cravings in men. While men do experience food cravings, they are generally less intense and less influenced by hormonal changes than those experienced by women.

Types of foods craved

Research indicates that men and women may crave different types of foods. Men are more likely to crave savory or protein-rich foods, whereas women tend to crave sweet foods, especially during certain phases of the menstrual cycle.

Additionally, while both genders experience emotional eating, studies suggest that women are more likely to eat in response to negative emotions, whereas men may do so in response to positive emotions.

Social and psychological influences

Both men and women experience social and psychological influences on their food choices. However, women tend to be more influenced by societal expectations around dieting, body image, and emotional comfort from sweet foods.

Men’s cravings, while present, are less often driven by societal pressures related to appearance and dieting, making their relationship with food cravings comparatively less emotionally complex.

Ability to regulate cravings

Research indicates men often have greater ease in controlling or suppressing food cravings compared to women, potentially linked to their hormonal stability and differences in neural responses to food cues. Studies have demonstrated that men are better able to reduce neural activation associated with food cravings through cognitive strategies, indicating gender differences in the ability to manage food cravings effectively.Understanding these gender-specific differences in food cravings not only helps in recognizing why women often reach for sweets but also highlights opportunities for tailored dietary and psychological interventions to support women in managing cravings and improving overall health.
