A “90 minutes” theory for those who want to lose weight without changing the usual diet


Having come across this theory, my first reaction was irony and humorous stickers popping up in my mind, reading “What you need to eat to lose weight” and “If you want to lose weight, ask me how”. But after I looked more closely at the subject, a genuine interest in the proposed weight management arose.

The method is very simple: the first meal should be moved later by 90 minutes, and the last one— earlier by 90 minutes. For instance, if you usually have breakfast at 8 a.m., you need to postpone it until 9:30 a.m., and your 7 p.m. dinner, on the contrary, should now be scheduled for an earlier time—5:30 p.m.

At the same time, the program does not require any changes in the eating habits or the amount of food. The theory researchers are the leading scientists L. C. Ruddick-Collins and P. J. Morgan, who presented their results in a joint work titled “The Big Breakfast Study: Chrono‐nutrition influence on energy expenditure and bodyweight”, as well as their Japanese colleagues Shigenobu Shibata and Akiko Furutani, who put their two-year studies into an article “Chrono-nutrition and n-3 polyunsaturated fatty acid” in Folia Pharmacologica Japonica.

All of them agree that changing the meal times like that naturally results in the reduction of the number of main meals to 2 times a day, a more rational number of snacks between them, metabolism increase, weight loss, blood sugar level regulation and even sleep quality improvement, which, in turn, leads to the acceleration of cell regeneration and the rejuvenation of the body.

The coming winter is a great time to try this method for yourself, especially taking into account the seasonal decrease in outdoor activities.
