Do you find yourself reaching for sweets more often than you’d like? That intense craving for chocolate, cake, or sugary snacks may not just be about willpower. It could be your body’s way of telling you something important: you might not be getting enough protein.
Let’s break down what’s happening inside your body and how you can make simple changes that curb sugar cravings naturally.
The Science Behind Sugar Cravings and Protein Deficiency
According to Dr. Giles Yeo, a geneticist and professor at the University of Cambridge, not all calories are created equal. In his discussion on the Diary of a CEO podcast, he explains that:
“Protein calories keep you fuller for longer than fat or carbs because your body takes more energy to break down protein, and it travels further through your gut.”
This means that if you’re not getting enough protein throughout the day, your body might respond by triggering hunger signals, often in the form of sugar cravings, which are the fastest way to boost blood sugar levels and energy — albeit temporarily.
How Low Protein Affects Your Appetite
Here’s how it works
- Protein keeps you full – Unlike carbs, which digest quickly, protein slows down digestion and keeps you feeling satisfied.
- Low protein = unstable blood sugar – Without enough protein, your blood sugar dips and spikes, increasing your urge for sugary “quick fixes.”
- Brain signals – Your brain is hardwired to seek glucose when energy is low. If you’re not getting steady fuel, it will nudge you toward candy, pastries, or soda.
What Can You Do Instead?
1. Prioritize Protein-Rich Meals
Start each meal with a solid source of protein. Great options include
- Eggs and Greek yogurt for breakfast
- Chicken, fish, tofu, or legumes for lunch and dinner
- Protein smoothies or mixed nuts for snacks
2. Balance Your Macros
Every meal should ideally contain a balance of
- Lean protein
- Healthy fats
- Fiber-rich carbs (like vegetables, fruits, and whole grains)
This combination helps regulate appetite and reduce the need for sugar boosts.
3. Consider Supplement Support (If Needed)
At Siam Clinic, we always recommend addressing nutritional needs through whole foods first. But in some cases ,such as post-illness recovery, chronic fatigue, or vegan diets, Amino Acid IV Therapy, can help restore balance quickly and effectively.
💡 Important Note – We view IV nutrition therapy as a supportive tool, not a replacement for healthy eating.
Frequently Asked Questions (FAQ)
❓Why do I crave sweets even after eating?
If your meal lacked protein or fiber, your blood sugar may drop quickly, triggering sugar cravings. Try adding more protein to your meals to stay fuller longer.
❓Can IV therapy stop sugar cravings?
IV Amino Acid therapy helps restore nutrient balance in cases of deficiency. While it may reduce cravings related to malnutrition, it should be used alongside proper diet — not as a substitute.
❓What are signs I’m not eating enough protein?
- Constant hunger
- Sugar cravings
- Fatigue
- Hair thinning or brittle nails
- Frequent illnesses
❓Is protein really better than carbs for feeling full?
Yes. Scientifically, protein takes more time and energy to digest, helping you feel full longer than carbs or fats.
Final Thoughts
Craving sugar might be more than just a sweet tooth. It could be your body’s way of asking for better nutrition. By focusing on protein-rich meals and whole-food balance, you can curb cravings naturally and feel more energized throughout your day.
