Jessie Inchauspé

Inchauspé's research answers a question calorie counting never asks: does it matter what order you eat your food in? Using wearable blood sugar sensors (CGMs), she found that the same meal produces a noticeably different blood sugar curve depending on sequence. Vegetables first, then protein and fat, then starch and sugar last, produces a flatter curve than eating the same foods in reverse order. The meal stays identical. Only the sequence changes, and so does the spike.

RealFoods cites Inchauspé's published work on food order and meal composition as background for the fiber-first, starch-last advice in its articles. The Weight Impact Score is RealFoods' own modelled estimate. Inchauspé did not build the score, has not reviewed it, and does not endorse it.

Glucose Revolution lays out the science of how food order and composition shape blood sugar curves, and The Glucose Goddess Method turns it into a four-week protocol that keeps every food group on the table. Neither book asks anyone to eliminate carbohydrates or sugar, only to change the order and the company they are eaten in.

Much of Inchauspé's evidence comes from wearable blood sugar sensors (CGMs) that track blood sugar in real time rather than relying on a single fasting measurement. That data is what let her isolate food sequencing as a variable in the first place, since it captures the shape of the curve, not just a peak or an average. A bigger blood sugar spike generally calls in a bigger insulin response to bring it back down, so a flatter curve tends to mean less insulin is called in. Her broader contribution to nutrition science is treating blood sugar spikes as something a person can shape through timing and pairing, not just through what is eliminated from a plate.
