Why Some Diets Work for Others But Not for You

01 Oct Why Some Diets Work for Others But Not for You

You may have seen it happen: a friend cuts carbs and loses weight easily while you slog on; or a friend puts on 10 kilos, whereas your weight is just doesn’t climb (because diets are not always for just weight-loss); perhaps your coworker is killing it on a high-fat keto regimen, but when you try it out for yourself, you feel tired and cranky. It’s frustrating, right? The reality is, it’s not just about willpower or discipline. The answer may be in your DNA.

Welcome to the world of nutrigenomics — the science of how your genes and the food you eat interact. It’s a game-changer for understanding why diets don’t work the same way for everybody.

Genes, Food, and the Metabolism Puzzle

At its root, nutrigenomics is the study of how different people absorb and process nutrients like fats and carbohydrates. Within your DNA are small variations known as SNPs (single nucleotide polymorphisms) that affect how your body processes, stores and uses energy. These modest genetic glitches may even account for how two people can share the same meal yet wind up with very different results.

For example:

• • Carbohydrates: Some have variants in the AMY1 gene, which affects how well they digest starch. They may thrive on high-carb diets, while others feel constantly bloated or gain weight.
  • Fats: Genes such as APOA2 or FTO can change how the body deals with dietary fats, including whether they’re stored and their effect on cholesterol levels. That’s why your friend is thriving on keto while you feel blobby and tend to gain weight.
  • Caffeine: Yes, your morning coffee routine is even spelt out in your genes! Fast vs. slow caffeine metabolisers will feel entirely different effects on energy, focus and sleep.

Why ‘One-Size-Fits-All’ Diets Fail

Diets are based on averages — the minute you start comparing yourself to an average of any kind, you’re probably going to get it all wrong. If a diet doesn’t match your genetic inclinations, you may find yourself struggling with:

• Weight plateaus despite eating “perfectly.”
• Energy crashes and irritability.
• Digestive trouble, such as bloating or cramps.
• Frustration that results in quitting.

And, in the meantime, another person on that same trajectory might be flourishing, and you wonder what you have done incorrectly. Spoiler: it’s not you. It’s simply your biology asking for something different.

How to Put Nutrigenomics Into Practice

1. Test, don’t guess. DNA health testing is a basis for individualised nutrition.
2. Adjust your macros. According to your genotype, you know whether your body performs best with more carbs, fats or protein.
3. Optimise lifestyle factors. Genes also affect sleep, stress responses and exercise — all important to getting the most out of your diet.
4. Reassess over time. Your genes don’t change, but your environment does. Matching DNA insight with routine health check-ins keeps you on track.

Nutrigenomics and epigenetics go hand-in-hand. Be sure to read about epigenetics fundamentals: myths and facts you should know.

The Bottom Line

If you’ve ever suspected the secret to dieting success was a mystery — it’s not. It’s written in your genes. Nutrigenomics provides a powerful answer for why your BFF’s miracle plan doesn’t work for you, and why aligning your diet with your DNA is the more intelligent and sustainable option.

We at YOLO Health believe the answers are all in your genes. With our DNA Health Test Kit, you gain personal insights into how your body responds to food, enabling you to discover a diet that works with your body—instead of against it.

Because your genes talk, and we translate.
