Hunger Hacks: 7 Ways to Reduce Cravings When Dieting

Dieting can be a challenging endeavour, particularly when the pangs of hunger strike with ferocity. Cravings often derail the best-laid plans, leading to a cycle of frustration and failure. However, understanding the science behind hunger and employing evidence-based strategies can significantly reduce cravings and improve the likelihood of long-term success. In this article, we will explore seven scientifically-backed methods to help you curb cravings while dieting.

Understanding Hunger and Cravings

Before diving into specific strategies, it’s essential to understand the difference between hunger and cravings. Hunger is the physiological need for food, driven by the body’s energy requirements. It is regulated by complex interactions between the brain, digestive system, and hormones such as ghrelin and leptin (St-Onge et al., 2004). Cravings, on the other hand, are a psychological desire for specific foods, often high in sugar, fat, or salt, which may or may not align with actual hunger (Hill, 2007).

Cravings can be triggered by a variety of factors, including emotional states, environmental cues, and even the body’s microbiome (Stevenson et al., 2017). By addressing these factors with targeted strategies, it’s possible to reduce the intensity and frequency of cravings, making it easier to stick to a diet.

1. Increase Protein Intake

The Science Behind Protein and Satiety

One of the most effective ways to reduce cravings is to increase your protein intake. Protein is known to be the most satiating macronutrient, meaning it helps you feel fuller for longer. This effect is due to protein’s ability to reduce levels of the hunger hormone ghrelin while increasing the release of peptide YY (PYY), a hormone that signals satiety to the brain (Blom et al., 2006).

Practical Application

To harness the hunger-reducing power of protein, aim to include a source of protein with every meal and snack. Good sources include lean meats, fish, eggs, dairy products, legumes, and plant-based proteins like tofu and tempeh. Research suggests that consuming approximately 25–30% of your total daily calories from protein can significantly reduce appetite and decrease calorie intake (Weigle et al., 2005).

2. Stay Hydrated

Hydration and Appetite Regulation

Dehydration is often mistaken for hunger, leading to unnecessary snacking and increased calorie intake. The hypothalamus, the part of the brain that regulates both hunger and thirst, can send mixed signals when the body is dehydrated, making you think you’re hungry when you actually need water (Mack et al., 2015).

Practical Application

To prevent dehydration-induced cravings, aim to drink at least 2–3 litres of water per day, depending on your activity level and climate. A good habit is to drink a glass of water before meals; this not only ensures hydration but may also help reduce the amount of food consumed by promoting a sense of fullness (Dennis et al., 2010).

3. Eat Fibre-Rich Foods

Fibre’s Role in Reducing Hunger

Fibre plays a critical role in appetite regulation by slowing down digestion and promoting feelings of fullness. Soluble fibre, in particular, forms a gel-like substance in the gut, which slows the absorption of nutrients and prolongs satiety (Slavin, 2005). Additionally, fibre-rich foods tend to be lower in calories, allowing you to eat larger volumes without significantly increasing your calorie intake.

Practical Application

Incorporate a variety of high-fibre foods into your diet, such as fruits, vegetables, whole grains, legumes, nuts, and seeds. Aim for a daily intake of at least 25–30 grams of fibre, which has been shown to significantly reduce hunger and support weight loss (Howarth et al., 2001).

4. Get Adequate Sleep

Sleep and Appetite Hormones

Sleep is a critical, yet often overlooked, factor in appetite regulation. Inadequate sleep disrupts the balance of hunger-related hormones, particularly ghrelin and leptin. Ghrelin, which stimulates appetite, tends to increase with sleep deprivation, while leptin, which signals fullness, decreases (Taheri et al., 2004). This hormonal imbalance can lead to increased hunger and cravings, particularly for high-calorie, carbohydrate-rich foods.

Practical Application

To support optimal appetite regulation, aim for 7–9 hours of quality sleep per night. Establish a regular sleep routine, limit caffeine intake in the afternoon, and create a sleep-friendly environment by keeping your bedroom cool, dark, and quiet. If you struggle with sleep, consider consulting a healthcare provider for further advice.

5. Manage Stress

The Connection Between Stress and Cravings

Stress is a powerful trigger for cravings, particularly for comfort foods that are high in sugar and fat. This is due to the release of cortisol, a stress hormone that increases appetite and can lead to emotional eating (Dallman et al., 2003). Furthermore, chronic stress can disrupt the body’s ability to regulate blood sugar levels, leading to energy crashes that trigger cravings.

Practical Application

Managing stress is crucial for controlling cravings. Incorporate stress-reducing activities into your daily routine, such as exercise, meditation, deep breathing, or spending time in nature. Research has shown that mindfulness-based stress reduction techniques can significantly reduce the frequency and intensity of food cravings (Alberts et al., 2010).

6. Practise Mindful Eating

The Benefits of Mindful Eating

Mindful eating is the practice of paying full attention to the experience of eating, without distraction. This approach helps you become more aware of your body’s hunger and satiety signals, which can prevent overeating and reduce cravings. Studies have shown that mindful eating can decrease the frequency of binge eating episodes and promote a healthier relationship with food (Kristeller & Wolever, 2011).

Practical Application

To practise mindful eating, start by eliminating distractions during meals, such as television or smartphones. Eat slowly, savouring each bite, and pay attention to the flavours, textures, and sensations of your food. Notice your hunger and fullness cues, and stop eating when you feel satisfied, not stuffed.

7. Choose Satiating Foods

Understanding Satiety Index

Some foods are more satiating than others, meaning they keep you full for longer periods. The Satiety Index, developed by Susanna Holt, ranks foods based on their ability to satisfy hunger relative to their calorie content (Holt et al., 1995). Foods that score high on the Satiety Index, such as boiled potatoes, oats, and legumes, can help control hunger and reduce overall calorie intake.

Practical Application

Incorporate high-satiety foods into your diet to manage hunger effectively. Focus on whole, minimally processed foods that are rich in fibre, protein, and water content. For example, boiled potatoes are extremely filling and can be a great addition to meals when trying to reduce cravings. Similarly, foods like Greek yoghurt, apples, and eggs are excellent choices for snacks due to their high satiety.

Conclusion

Reducing cravings while dieting is not just about willpower; it’s about understanding the physiological and psychological factors that drive hunger and employing strategies to manage them effectively. By increasing protein intake, staying hydrated, eating fibre-rich foods, getting enough sleep, managing stress, practising mindful eating, and choosing satiating foods, you can significantly reduce cravings and improve your chances of long-term success.
