Πρωινό VS Βραδινό Γεύμα - Breakfast vs Dinner !!!

Μεγάλη διαμάχη ανα διαστήματα γίνεται για το πόσο σημαντικό είναι το πρωινό και κατά πόσο ωφελεί να το παραλείπουμε. Η παρακάτω έρευνα δείχνει ότι τρώγοντας ένα σωστό και μεγάλο πρωινό είναι περισσότερο ωφέλιμο στη μείωση βάρους αλλά και στον μεταβολισμό, σε σύγκριση με ένα μεγάλο βραδινό (ίδιας θερμιδικής και διατροφικής αξίας) σε υπέρβαρες/παχύσαρκες γυναίκες.
Αυτό δεν σημαίνει απαραίτητα πως επιβάλλεται να τρώμε τεράστιες ποσότητες το πρωί, όσο το μήνυμα πως δεν πρέπει να παραλείπουμε το πρωινό μας, όπως προτείνουν ανα καιρούς «επαναστατικές» δίαιτες.



High Caloric intake at breakfast vs. dinner differentially influences weight loss of overweight and obese women.

OBJECTIVE:

Few studies examined the association between time-of-day of nutrient intake and the metabolic syndrome. Our goal was to compare a weight loss diet with high caloric intake during breakfast to an isocaloric diet with high caloric intake at dinner.
DESIGN AND METHODS:

Overweight and obese women (BMI 32.4 ± 1.8 kg/m2 ) with metabolic syndrome were randomized into two isocaloric (1400 kcal) weight loss groups, a breakfast (BF) (700 kcal breakfast, 500 kcal lunch, 200 kcal dinner) or a dinner (D) group (200 kcal breakfast, 500 kcal lunch, 700 kcal dinner) for 12 weeks.
RESULTS:

The BF group showed greater weight loss and waist circumference reduction. Although fasting glucose, insulin, and ghrelin were reduced in both groups, fasting glucose, insulin, and HOMA-IR decreased significantly to a greater extent in the BF group. Mean triglyceride levels decreased by 33.6% in the BF group, but increased by 14.6% in the D group. Oral glucose tolerance test led to a greater decrease of glucose and insulin in the BF group. In response to meal challenges, the overall daily glucose, insulin, ghrelin, and mean hunger scores were significantly lower, whereas mean satiety scores were significantly higher in the BF group.
CONCLUSIONS:

High-calorie breakfast with reduced intake at dinner is beneficial and might be a useful alternative for the management of obesity and metabolic syndrome.
