It was confirmed by the studies of a researcher in Tel Aviv University that breakfast helps losing weight and reduces risks of diabetes, hypertension and cardiac problems
With a hope to lose weight or to stay healthy, we think it is very crucial what we eat. But researches in Tel Aviv University found that it's not just what you eat - but when.
Metabolism is impacted by the body's circadian rhythm - the biological process that the body follows over a 24 hour cycle. So the time of day we eat can have a big impact on the way our bodies process food, those who eat their largest daily meal at breakfast are far more likely to lose weight and waist line circumference than those who eat a large dinner.
And the benefits went far beyond pounds and inches. Participants who ate a larger breakfast – even a dessert item such as a piece of chocolate cake or a cookie - also had significantly lower levels of insulin, glucose, and triglycerides throughout the day, translating into a lower risk of cardiovascular disease, diabetes, hypertension, and high cholesterol. These results, published recently in the journal Obesity, indicate that proper meal timing can make an important contribution towards managing obesity and promoting an overall healthy lifestyle.
Breakfast makes the difference
To determine the impact of meal timing on weight loss and health, Prof. Jakubowicz and her fellow researchers conducted a study in which 93 obese women were randomly assigned to one of two isocaloric groups. Each consumed a moderate-carbohydrate, moderate-fat diet totaling 1,400 calories daily for a period of 12 weeks. The first group consumed 700 calories at breakfast, 500 at lunch, and 200 at dinner. The second group ate a 200 calorie breakfast, 500 calorie lunch, and 700 calorie dinner. The 700 calorie breakfast and dinner included the same foods.
By the end of the study, participants in the "big breakfast" group had lost an average of 17.8 pounds each and three inches off their waist line, compared to a 7.3 pound and 1.4 inch loss for participants in the "big dinner" group. According to Prof. Jakubowicz, those in the big breakfast group were found to have significantly lower levels of the hunger-regulating hormone ghrelin, an indication that they were more satiated and had less desire for snacking later in the day than their counterparts in the big dinner group.
