Feeling Tired After Lunch…Then Look At Your Diet!

So we know that carbohydrates are your bodies preferred energy source, and we know that they deliver 4kcal of energy per gram, heck we even understand that carbs play a big part in maintaining blood sugar levels…then why is it some of us choose ignore them, or even exclude them completely from their diets…#notthewaytogo!

Ever finish your lunch and want nothing more than to curl up and go to sleep? Well, a new study presented by the American Academy of Sleep Medicine emphasises the role fat has to play in this too. A high fat diet was associated with objective daytime sleepiness, while a diet that is higher in carbs increased alertness!

Apparently these findings are independent of gender, age, weight and body mass index (BMI), as well as their normal sleep pattern and total calorie intake. Professor Vgontzas explains how a fatty meal negatively affects alertness in healthy, non- obese individuals meaning the nutritional composition of your meals deserves due consideration. Be sure to include a starchy carb approx 3 times a day in order to drip feed your body with glucose increasing energy, controlling insulin levels and giving you that controlled surge you need for whatever it is your afternoon has in store.

Starchy carb sources: Pasta (wholegrain/brown is ideal), rice (brown/basmati is ideal), potato, sweet potato, wholegrain bread, ryvita, rice cakes and wholegrain cereals.

The husk and complete nature of wholegrain carbs mean that the sugar within is released more slowly minimising energy peaks and troughs and thus no crashes in alertness!
