Biochemical survival for young parents – Blog 2
Why do I suddenly crave sugar so much?
You’ve just finished a quick breakfast – usually standing, using one hand to prepare a bottle or trying to get a child into the high chair. An hour later, you find yourself already reaching for something sweet. Around four in the afternoon, you feel sluggish, irritable and tired. Your hand automatically looks for a cookie or chocolate bar because you feel like you need something to go on.
For many young parents, this is recognizable. Whereas before you could do just fine for a day without sugar, now it seems like your body is actively asking for it. This sudden need for sugar is not a matter of weakness or lack of self-discipline, but a reaction of your body to exhaustion and unstable blood sugar levels.
What exactly is going on?
Your body is in a heightened state of stress and fatigue. Irregular sleep, constant mental alertness, quick meals and little recovery cause your internal balance to be disrupted. Your brain – which is responsible for about a quarter of your energy consumption – notices this first. And when it runs low on fuel, it sends a powerful signal: give me quick energy.
Glucose (sugar) is the fastest and easiest source of fuel for your brain. So the moment your system experiences shortages, it instinctively chooses something sugary. The result: you end up in a cyclical pattern of:
Fatigue → Eating sugar → Short energy boost → Quick relapse → Even more fatigue → Need sugar again.
Why does this happen biologically?
Your sugar addiction is not a character flaw. There are three main biochemical mechanisms at play:
1. Energy crisis in the brain
Your brain consumes about 20-25% of all the energy in your body. If your mitochondria were already approaching their limit (as we discussed in Blog 1), your brain goes into panic mode faster and sends the signal, “SUIKER NOW!”
2. Dopamine dip caused by stress
Caring for a baby often means fewer social stimuli, less exercise, less sunlight and few pleasurable activities. All this lowers your dopamine production. Sugar gives this neurotransmitter an instant kick. According to Psychology Today, sugar acts on the same reward centers in your brain as addictive substances such as nicotine and alcohol.
3. Dysregulated blood sugar levels
Irregular eating, coffee on an empty stomach and not enough protein cause blood sugar fluctuations. Your blood sugar drops → adrenaline rises → your brain wants quick fuel → sugar.
What can you realistically do?
Eating perfectly as a young parent is unachievable. However, small, achievable adjustments can make a lot of difference:
1. Start the day with protein + fat
Eggs, yogurt, nuts: this stabilizes your blood sugar. Coffee on an empty stomach? That actually provokes a crash.
2. Hydrate first
Many “cravings” are actually thirsty. Start your day with a large glass of water, possibly with a pinch of salt or electrolyte powder.
3. Mini walk after meals
Five to 10 minutes of walking helps regulate your blood sugar levels. Ideal with your baby in the sling – micro habit, macro effect.
4. Use adaptogens
Ashwagandha, rhodiola or maca can soothe your stress response, reducing cortisol and sugar surges.
How does NMN help – and how does it fit into the bigger picture?
As discussed in Blog 1, NAD+ plays a key role in energy metabolism. That role extends to your glucose processing and insulin sensitivity. Simply put: more NAD+ = more stable blood sugar, better blood sugar = fewer energy crashes, fewer crashes = less sugar addiction.
What does science say?
A randomized study showed that daily supplementation of 250 mg of NMN in women with prediabetes led to improved insulin sensitivity in skeletal muscle. Another clinical analysis confirmed that NMN affects glucose uptake and metabolic flexibility, especially in those with increased oxidative stress. However, a meta-analysis in Springer Diabetes Therapy does nuance that the effect may depend on the target population: people with insulin resistance seem to benefit more than healthy adults.
You are not “weak” – your body seeks balance
It’s okay to reach for a cookie sometimes. Understanding why you do so allows you to make more conscious choices. Biochemical recovery is not a perfectionist project. It is a process of nourishing, hydrating, regulating and supporting – tailored to what your life allows right now.
Next time, “Why is my brain so fuzzy since I got older?“
Say hello to the phenomenon we call “mom brain” or “dad fog. What many parents don’t know: deep biochemical processes also play a role here, from reduced energy in brain cells to disrupted neurotransmitters. That’s the topic of Blog 3.
