Introduction

December is a joyful month — gatherings, celebrations, festive food, late-night suppers, sweet treats, and comfort eating. But along with the joy comes something almost every Malaysian says:

“I always gain weight during December.”

Yet, not everyone gains the same amount.
Some people eat a lot but stay the same.
Some gain weight extremely quickly.
Some feel bloated and inflamed after just a few meals.
Some struggle to lose the weight afterwards.

This difference is not just willpower or discipline.
It is influenced by genetic metabolism patterns, appetite regulation, blood sugar response, and inflammation tendencies.

Understanding these patterns helps you navigate the holiday season with greater self-awareness — without guilt, shame, or unrealistic expectations.

1. Holiday Season = High-Calorie + High-Stress Month

December meals often contain:

• Rich curries
• Cookies and pastries
• Fried snacks
• Sugary drinks
• Supper outings
• Excess carbs and fats
• Larger portions
• Multiple gatherings in one week

Most people eat more than usual because:

• Social pressure
• Emotional eating
• Celebration mood
• Travel routines
• Stress from year-end deadlines
• Less structured meals
• Reduced physical activity

But genetics determines how your body responds to all this food.

2. Appetite Genes Influence How Much You Feel Like Eating

Some people naturally feel full faster; others continue eating even when full.

NGx identifies genes that influence:

✔ Appetite control

Some individuals experience weaker satiety signals — meaning they don’t feel full quickly.

✔ Craving intensity

Certain genetic variants heighten reward response for:

• Sweet foods
• High-fat foods
• Carbs during stress
• Late-night snacking

✔ Stress eating

People with COMT stress sensitivity may reach for comfort food more frequently.

This explains why two people can sit at the same table, eat the same meal, but respond differently.

3. Sweet Sensitivity & Sugar Spikes

Some Malaysians have genetic sweet sensitivity that influences:

• Craving for sweet foods
• How sugar affects mood
• How sugar spikes drive hunger

People who are less sensitive to sweetness tend to consume more sugary items to feel satisfied.

During December, this leads to:

• More sugar intake
• Faster fat storage
• Higher inflammation
• Afternoon crashes
• Late-night hunger cycles

NGx helps identify this trait clearly.

4. Fat Storage & Metabolism: Why Some Gain Weight Faster

NGx traits reveal how efficiently your body stores or burns calories.

✔ Efficient fat storers

Your body stores excess calories quickly → weight gain happens fast.

✔ Slow fat mobilisers

Harder to burn fat → weight gained is difficult to lose.

✔ Carbohydrate-sensitive individuals

Experience quick blood sugar spikes → fat accumulation increases.

✔ Higher inflammation responders

Inflammation increases water retention, bloating, and weight fluctuations.

These are NOT your fault — this is biology.

5. Omega-3 EPA, Inflammation & Holiday Weight Gain

Most festive meals in Malaysia involve:

• Fried foods
• Sweet foods
• Processed items
• Oils high in Omega-6

People with low Omega-3 EPA conversion genetically experience:

• Stronger inflammation
• Easier bloating
• Slower recovery after heavy meals
• Higher fat accumulation in the liver
• More water retention

EPA is anti-inflammatory.
Low conversion → more inflammation → more weight gain.

NGx can reveal if your body struggles to convert plant-based Omega-3 into usable EPA.

6. Vitamin D, Mood & Holiday Eating Patterns

Vitamin D influences:

• Serotonin
• Appetite
• Sleep
• Energy
• Cravings

People with low Vitamin D activation often experience:

• Emotional eating
• Sugar cravings
• Low motivation to exercise
• Stress sensitivity
• Sluggish metabolism

Holiday mood dips — due to fatigue, social pressure, or stress — can amplify cravings.

---

7. Gut Sensitivity & Holiday Foods

Malaysians with sensitive digestive genetics may experience:

• Bloating
• Diarrhoea
• Constipation
• Gastric flares
• Slow digestion

This leads to:

• Eating irregularly
• Skipping meals
• Overeating later
• Excess calorie intake
• Feeling lethargic

Understanding your gut sensitivity helps you plan festive eating with more comfort.

8. Holiday Weight Gain is Not About Willpower — It’s About Personal Biology

People often blame themselves:

• “I always overeat.”
• “I have no discipline.”
• “Everyone else eats the same but they don’t gain weight!”

But NGx shows that bodies process food differently.

Weight gain is influenced by:

• Appetite genes
• Craving genes
• Sweet sensitivity
• Fat storage genes
• Carbohydrate response
• Metabolism speed
• Inflammation response
• Vitamin D activation
• Omega-3 EPA conversion
• Stress genes (COMT)

Knowing your tendencies removes the guilt and replaces it with personalised strategy.

9. Case Example (Anonymised)

A 37-year-old man noticed:

• He gained 3–5 kg every December
• Felt bloated and tired after gatherings
• Ate more when stressed
• Could not control sugar cravings

NGx results revealed:

• Low satiety sensitivity
• Sweet craving gene
• Low Omega-3 EPA conversion
• High inflammation tendency
• COMT intermediate (stress eater)

His personalised approach:

• Eat protein first
• Add EPA supplementation
• Reduce fried food by 20–30% (not total removal)
• Keep Vitamin D levels optimal
• Plan breaks between gatherings
• Increase steps after meals

In 6 weeks:

• He gained only 0.8 kg (vs usual 4–5 kg)
• Felt lighter, clearer, and less bloated
• Improved mood and energy
• Better control without restriction

This is personalised holiday health.

10. How to Navigate the Holiday Season With Your Genetics in Mind

✔ Eat protein before carbs

Enhances satiety and reduces sugar spikes.

✔ Prioritise Omega-3 EPA

Balances inflammation from festive foods.

✔ Keep Vitamin D optimal

Supports mood, appetite, and metabolism.

✔ Slow down eating

Allows satiety signals to activate.

✔ Avoid going to gatherings hungry

Reduces overeating risk.

✔ Manage stress

Reduces emotional eating.

Understanding your tendencies makes this effortless — not restrictive.

Conclusion

Holiday weight gain is complex, and genetics play a major role.

NGx gives you clarity on:

• Why you crave certain foods
• Why you gain weight faster
• Why the same meal affects others differently
• Why your digestion responds uniquely
• Why motivation or energy changes
• Why inflammation increases

The goal is not to remove joy from the holiday season.
The goal is to support your body in the way it needs, so you can enjoy food comfortably, happily, and mindfully.

Personalised health reduces guilt and replaces it with awareness, confidence, and balance.
