The Effects of Different High-Protein Low-Carbohydrates Proprietary Foods on Blood Sugar in Healthy Subjects

Abstract

The aim of our work was to analyze the effects on blood sugar through the calculation of the glycemic score (GS) of 10 different high-protein-low-carbohydrates proprietary foods which are commonly used as meals during very low carbohydrate ketogenic diet or during low carbohydrate diet. 14 healthy female tested the glycemic response curve elicited by 1000 Kj of glucose three times within 3 weeks period (1 test each week) compared to each of the 10 test-foods once on separate days twice a week. After determining the GS of each food in each individual, the mean GS of each test food was calculated. All test foods, compared to glucose, produced a significantly lower glycemic response . The GS of all test foods resulted lower than 25 and the difference between the mean glycemia after the intake of glucose (mean 122 ±15 mg/dl) and after the intake of the sweet test foods (mean 89 ± 7 mg/dl) was of 33 mg/dl (P<0.001), whereas that after the intake of glucose and the savory test foods (mean 91 ± 8 mg/dl ) was of 31mg/dl (P<0.001). We can conclude that the reformulation of ultra-processed ready-to-consume foods in a low carbohydrate, high protein version can produce a significant low glycemic response while maintaining the valued ready-to-use format and high palatability demanded by consumers. The low impact on postprandial glycemia and the nutritional characteristics of these proprietary foods make them useful both in weight control and in diabetes care dietary management.

Effects of Two Months of Very Low Carbohydrate Ketogenic Diet on Body Composition, Muscle Strength, Muscle Area, and Blood Parameters in Competitive Natural Body Builders

“…KD effect on insulin and glycemic control deserves mention. Several researches have demonstrated that KD can reduce glucose and insulin concentration in obese, insulin resistant individuals and diabetics [72][73][74][75]. This effect is not only related to a reduced intake of glucose within the diet, but also to the improvement in insulin sensitivity [12].…”

“…Moreover, subjects daily consumed four food supplements and liquid herbal extracts. Food supplements are high proteins (19 g/portion) and very low carbohydrate (3.5 g/portion) formulas simulating the aspect and taste of common carbohydrate rich foods added with dry phytoextracts [43]. Liquid herbal extracts were used for their draining/toning activity, useful to Table 3.…”

“…A nutritional protocol as the KD may be hard to be maintained for long periods due to the lack of sweet taste [25], thus, for this reason, in the last years, many ready-to-eat ketogenic products (RKP) have been created [26] in addition to usual low carbohydrate foods [27]. In our protocol we used some RKP as a ketogenic pasta (selected with a ketogenic ratio of fats: protein+carbohydrate equal to 4:1) (Le Gamberi Foods, Forlì, Italy), and other RKP (specialty meals and drinks) that mimics the taste of carbohydrates [27], constituted principally of high-quality protein (18 g of protein per portion), fibers, and electrolytes (mainly magnesium and potassium) [28] (Tisanoreica® by Gianluca Mech S.p.A., Asigliano Veneto, Vicenza, Italy). It has been demonstrated that the use of RKP increases the adherence to the ketogenic nutritional protocol [25,29,30].…”
