Plate It Right!
To bite or not to bite
Eating habits differ from one person to another. Each of us have our own preferred gourmet taste, portion sizes and sweet cravings – to name a few.
Whether you’re a foodie who loves to hit every new restaurant in town, or love nibbling on Oreos as a midnight snack or even if you are someone who savours each bite and eats very slowly, there are two common hormones that decide if you’re hungry or feeling full.
These two regulatory hormones in our body are leptin and ghrelin. Leptin suppresses the appetite while ghrelin increases the appetite. They collectively influence the food–energy balance in our body. Circulating levels of leptin and ghrelin are responsible for neurological signals that make you stop eating when you are full or vice versa.
Different phenotypes observed in food habits
|The “Nibbler”||Suppressed appetite- both
|The Over-eater, generally overweight/obese||Increased appetite,
irregular meal-times, also suffers from leptin resistance
|The “Crash” eater, both
|Eats nothing for hours
together, and then eats everything in sight. Hormones and metabolism usually
goes out of whack.
|The Lucky one (also known
as the “thin-fat”
|Eats anything and gets away
with it. Very high Basal Metabolic Rate.
Why you eat the way you do-
Genetic variations in several genes are linked with energy balance, hormone regulation and dietary preferences. Screening for these genetic factors can be an effective tool to assess your metabolic function and eating behaviour.
Example of a “genetic effect”
Normal gene sequence → Regular hormonal function → Appetite “on” and “off” at regular intervals
Variation in gene sequence → Hormones go out of sync → Appetite “on” → Overeating
How does our genetic test help?
- Long-lasting results
- Reduced (or zero) probability of weight re-gain
- Holistic wellness design rather than “poster-girl/boy look”
- Best suited for an individual’s innate food preferences
Surprised to read the last part? Yes, the best-kept secret to effective weight management is that ‘you must please your palate’.
By analyzing one’s basic predisposition towards food intake, genetic testing takes nutritional medicine to a new level. A genetically-personalized diet plan would bring optimal results, rather than a rhetorical ‘yes to fruits’ and ‘no to sweets’. Before you get yourself a monthly diet/fitness chart, get tested with SlimGene or MyFitGene. Know the real ‘you’ to see a better you!
