Many women over 40 report gaining weight despite maintaining the same diet and activity levels they had in their 30s. According to data from the Centers for Disease Control and Prevention, nearly two-thirds of American women between 40 and 59 are currently overweight — and the majority have tried at least one weight loss approach without lasting results.
Researchers at Oxford University have identified a key factor that is often overlooked in standard weight loss advice: the significant decline of two metabolic hormones — GLP-1 and GIP — that occurs naturally in women after the age of 40.
These hormones play a central role in regulating appetite, metabolism and fat storage. When their levels are balanced, the body uses stored fat efficiently for energy. When they decline — as they commonly do after 40, due to dietary changes, processed food intake and hormonal shifts — the body's ability to burn stored fat may be significantly reduced.
A study published by Harvard University researchers found that specific compounds naturally present in pure gelatin — glycine and alanine — may support the body's own production of GLP-1 and GIP hormones. When combined with a mineral-rich pink salt from the Okinawa region of Japan, researchers observed a measurable improvement in metabolic hormone levels in women over 40.
This finding is consistent with population data from Okinawa, Japan — a Blue Zone region where women maintain a healthy body weight well into their 60s and 70s without restrictive dieting. Research conducted with island residents found their GLP-1 and GIP levels to be significantly higher than those of the average American woman in the same age group.
A Columbia University-trained physician has now compiled these findings into a straightforward morning routine — combining pure gelatin with Okinawa pink salt — and is presenting the full method in a free educational video.

For women over 40 who have followed standard weight loss advice — reducing calories, increasing physical activity — without achieving consistent results, the hormonal explanation may be particularly relevant.
Standard diet programs are generally designed around caloric intake and expenditure. However, when GLP-1 and GIP hormone levels are significantly reduced, the body's metabolic response to these interventions may be limited — regardless of the effort involved.
Pure gelatin contains glycine and alanine — amino acids that Harvard researchers identified as natural stimulants of GLP-1 and GIP hormone production. The Okinawa pink salt, recognized by researchers for its high mineral content, provides additional support for metabolic hormone regulation. Together, this combination may help restore the hormonal balance that supports healthy fat metabolism in women over 40.
The complete method — including the exact preparation, ingredient ratios and the science behind each component — is presented in full in a free educational video by Dr. Jennifer Ashton.
