[0051] The following examples are intended to illustrate the invention and should not be interpreted as limiting the invention in any way.

[0052] In order to evaluate the effect of an embodiment of the lipid-based composition according to invention, a pilot study was designed as a clinical trial, on the sensitivity to insulin, cardiovascular risk factors, composition and body weight in people with risk of diabetes.

[0070] Follow-up: A one-week induction phase is carried out to evaluate adherence to the intake of the assigned composition

[0071] Measurements:

[0072] Tests performed for the three study groups at the beginning and at the end of the follow-up (week 0 and week 8): [0073] Anthropometric assessment, blood pressure and body composition. [0074] Physical activity by iPAQ. [0075] Basal consumption. Total calories, carbohydrates, proteins, total lipids, saturated fatty acids, monounsaturated, polyunsaturated and trans, EPA, DHA, dietary cholesterol, and 15 micronutrients: Calcium, iron, sodium, phosphorus, zinc, potassium, vitamin A, vitamin E, vitamin K, vitamin D, thiamine, riboflavin, niacin, vitamin C and folate. [0076] Insulin sensitivity: oral glucose tolerance test with glycemia and insulinemia, determination of insulin sensitivity and resistance indexes, glycosylated hemoglobin [0077] Carbohydrate and lipid metabolism (lipid profile, triglycerides, total cholesterol, LDL, HDL); hepatic (liver transaminases, gamma-glutamyl transferase) and renal function (creatininemia, urinary albumin excretion) and low-grade inflammation (C-reactive protein) tests. [0078] Gastrointestinal hormones for regulating appetite and metabolic rate: [0079] GLP-1 [0080] Ghrelin [0081] Glucagon [0082] These hormones were measured at minute zero (preload) and at 120 minutes post glucose load, both at the beginning and at the end of the study. [0083] Adipokines produced by adipose tissue and responsible for regulating body metabolism: [0084] Leptin [0085] Adiponectin [0086] Resistin [0087] These hormones were measured at the beginning and at the end of the follow-up (week zero and week 8). [0088] Myochines that influence the metabolism in muscle and other tissues: [0089] Irisin [0090] Mionectin [0091] FGF-21 [0092] These hormones were measured at the beginning and at the end of the follow-up (week zero and week 8). [0093] Determination of adverse events; for the baseline visit, the follow-up and the final visit.

[0094] Tests performed on the three study groups, at the beginning, at 4 weeks and at 8 weeks of follow-up: [0095] Change in: Weight, body mass index, body fat %, waist circumference.

[0096] Study's results:

Study Group Baseline Characteristics:

[0097] The average age for the three groups is between 28 and 35 years. The average body mass index (BMI) is in the overweight range. Participants also have, on average, a high waist circumference and body fat percentage, and average C-reactive protein levels above 1 mg/mL, indicating chronic low-grade inflammation. The daily level of physical activity of the participants is low in the three groups, while the amount of seated time exceeds 350 minutes/week in the three groups. There are no significant differences in the baseline characteristics of the participants of the three study groups, nor in their basal intake.

Anthropometric Variables:

[0098] After the 8-week follow-up period, it was found that the intake of the lipid-based composition with micronutrients of the invention did not show significant effects on the weight, body mass index and muscle mass of the patients. However, significant differences were found in the change of waist circumference between the low dose and high dose groups versus the control group (data not shown). Thus, the lipid-based composition of the invention appears to have no adverse effects on anthropometric measurements.

Change in Indexes Associated with Glycemia, Insulin Resistance and Insulin Secretion:

[0099] According to what is shown in FIG. 1, the glycosylated hemoglobin, which reflects the accumulated glycemic levels continuously during the last 3 months, decreased in the three study groups, although more markedly in the high dose group (−0.50) than in the dose group low (−0.16) and the control group (−0.36). However, there are no significant differences between groups.

[0100] Thus, the results show that the lipid-based composition of the invention does not adversely affect the glycosylated hemoglobin and, on the contrary, a tendency to improve the chronic glycemic levels expressed by HbA1c is observed, i.e., the composition is effective in its objective principal, which is to reduce blood glucose in patients at risk of diabetes. This reduction becomes more evident in the high dose group.

[0101] On the other hand, according to FIG. 2, the administration of a lipid-based composition with micronutrients according to the invention modified the body response to the load of 75 grams of glucose in the oral glucose tolerance test.

[0102] Thus, the administration of the lipid-based composition with micronutrients of the invention has blood glucose lowering effects after 8 weeks of follow-up. Additionally, significantly lower glycemic excursions were observed at 60 and 120 minutes. This effect is highly positive and validates the effectiveness of blood glucose reduction achieved by the lipid-based composition with micronutrients of the invention.

[0103] Also, according to FIG. 3, the incremental area under the glucose curve, which reflects the size of the glycemic excursion during an oral glucose tolerance test, was reduced with the administration of the lipid-based composition of the invention in both high and low doses, while it rose slightly in the control group. In this way, the reduction of blood glucose levels is confirmed at week 8 compared to the control group, thus verifying the effectiveness of the lipid-based composition with micronutrients in the reduction of blood glucose, and therefore showing prevention benefits in patients at risk of type II diabetes mellitus or hyperglycemia.

[0104] In the same way, as shown in FIG. 4, basal insulinemia rose slightly in all three study groups, especially in the low dose group. These results suggest that the reduction in glucose observed at 8 weeks may be associated with a higher insulin secretion and not a resistance to it.

[0105] Likewise, according to what is shown in FIG. 5, the measurement of insulin secretion after the glycemic challenge of the tolerance test, the incremental area under the glucose curve showed an increase in the high dose group compared to the other two groups, once again suggesting a positive effect of the lipid-based composition of the invention on insulin secretion.

[0106] Finally, FIG. 6 illustrates the results of a study of the Insulin Sensitivity Index-Gutt (ISI-Gutt), by means of which the capacity of the insulin secreted by the organism during a OGTT is quantified to stimulate the uptake of glucose in tissues peripherals Thus, ISI-Gutt is an indicator of insulin sensitivity that is not restricted to the fasting state alone and therefore allows a better measurement of insulin sensitivity.

[0107] In this way, it is evident that for both the low-dose and the high-dose groups, the ISI-Gutt improved (5.4% in the low-dose group and 10.1% in the high-dose group), whereas remained stable in the control group. These results show that the lipid-based composition of the invention has a favorable effect on the sensitization of insulin, a hormone directly associated with the uptake of glucose in adipose and muscle tissue, thus corroborating the effectiveness of the composition in the prevention of the development of diabetes.

[0108] Taking into account all of the above, it is evident that the lipid-based composition of the invention has positive and significant effects in the reduction of blood glucose, an increase in the sensitivity to insulin, as well as an improvement in the chronic glycemic levels in blood at the end of 8 weeks of follow-up.

Effects on Gastrointestinal Hormones, Adipokines and/or Myokines:

[0109] Measurements of different gastrointestinal hormones (Ghrelin, GLP-1, Glucagon), adipokines (Leptin, Adiponectin, Resitin) and myokines (FGF-21, Mionectin, Irisin) were performed to identify the metabolic mechanisms by which the lipid-based composition of the invention acts (Data not shown).

[0110] The administration of the lipid-based composition of the invention shows that there is a favorable dose-dependent effect on the secretion of the gastrointestinal hormone GLP-1, which favors the secretion of insulin. Since GLP-1 is an objective in the formulation of pharmaceutical molecules for the management of type 2 diabetes, this result shows that this metabolic pathway can also be positively affected by the intake of said composition.

[0111] Likewise, the administration of a lipid-based composition with micronutrients of the invention achieves a favorable and significant effect on the secretion of plasma leptin by adipocytes. Therefore, the intake of the lipid-based composition with micronutrients of the invention increases the efficiency of adipose tissue, metabolic expenditure and energy sufficiency.

[0112] On the other hand, the administration of a lipid-based composition of the invention achieves a favorable effect in increasing the secretion of plasma irisin in a dose-dependent manner. This significant increase in irisin shows that the lipid-based composition with micronutrients of the invention has a favorable effect on the physiology of the adipose tissue, in its particular differentiation towards ‘beige’ or brown adipose tissue. Likewise, the increase in this specific hormone shows the possible promotion of body thermogenesis that influences the energy and metabolic balance.

[0113] Regarding the other hormones (Ghrelin, Glucagon, Adiponectin, Resitin, FGF-21, Mionectin), their changes were not significant among the three groups, indicating that the composition of the invention seems to have no direct effect on secretion or inhibition of these hormones.

Change in Low-Grade Chronic Inflammation Indicator

[0114] Also, as shown in FIG. 7, the results of C-reactive protein measurements (clinical marker or indicator of chronic low-grade inflammation) show a positive and significant effect on the reduction of chronic low-grade inflammation associated with the intake of lipid-based composition with micronutrients of the invention. The reducing effect in this biomarker suggests that, in pre-diabetes states, risk of diabetes, metabolic syndrome, the composition of lipid and micronutrients of the invention manages to reduce the risk of cardiovascular disease.

Change in Liver and Kidney Function Variables

[0115] On the other hand, in order to evaluate the hepatotoxicity and renal toxicity of the lipid-based composition of the invention, measurements of hepatic transaminases and urinary excretion of albumin were made.

[0116] Thus, according to what is shown in FIG. 8, the levels of AST (marker of hepatocellular damage) decreased in the three groups, with the greatest decrease in the high dose group (40% on average). Hence, demonstrating a hepatoprotective and even a hepatostaurative side effect, which adds a benefit to the general condition of the metabolic syndrome that usually accompanies the stages of pre-diabetes or diabetes.

[0117] As for the ALT levels, shown in FIG. 9, the results showed a decrease only in the low dose group (16.8% on average).

[0118] On the other hand, as shown in FIG. 10, Gamma glutamyl transpeptidase (GGT) levels (hepatobiliary damage marker) decreased slightly in the high and low dose groups, while they increased slightly in the control group. This result suggests that the lipid-based composition of the invention offers hepatobiliary protection, usually associated with metabolic syndrome, and oxidative stress.

[0119] Finally, FIG. 11 teaches the results of the measurement of urinary albumin excretion (UAE), associated with a very early onset of glomerular renal dysfunction. In this way, it is evident that the UAE decreased in the three groups, presenting the greatest decrease in the high dose group (from 8.8 mg/g to 3.8 mg/g). The results also show that the administration of the lipid-based composition with micronutrients of the invention does not exert a renal damage, particularly in glomeruli.

[0120] As a consequence, it is possible to conclude that the oral administration of a lipid-based composition with micronutrients according to the invention has no hepatotoxic effect or negatively affects renal function. On the contrary, a positive effect was shown in the reduction of hepatic, hepatobiliary and renal glomerular dysfunction.

Change in Lipid Profile Indicators

[0121] FIG. 12 teaches the results of the measurement of total cholesterol where it is observed that Total Cholesterol decreased in the three groups.

[0122] For its part, in FIG. 13 it is evidenced how HDL cholesterol levels did not considerably change in the high dose group (−1.4 mg/dL), whereas they increased in the low dose (+3.1 mg/dL) and control (+5.7 mg/dL) groups.

[0123] On the other hand, FIG. 14 illustrates the results of the determination of triglycerides, which showed great intra- and interindividual variability. Thus, mean triglycerides were elevated in the control group (+12.2 mg/dL) and also in the low-dose group (+5.9 mg/dL), while they decreased in the high-dose group (−11.7 mg/dL).

[0124] Finally, FIG. 15 shows that favorable changes were found in the three study groups for LDL-C, the most atherogenic lipid fraction. The decrease was greater in the control group (−21.8 mg/dL) and low dose (−15.6 mg/dL), although the starting point of these two groups is considerably higher.

[0125] In this way, the administration of the control and of the lipid-based composition with micronutrients of the invention demonstrate positive effects on the lipid profile of the participants, which is related to the intrinsic properties of sunflower oil, a rich in polyunsaturated fatty acids. However, it is noteworthy that these positive effects, especially in the reduction of LDL cholesterol, speak well about the lipid-based composition with micronutrients of the invention, given the importance of this factor in cardiovascular risk.

[0126] In conclusion, the lipid-based composition with micronutrients of the invention clinically demonstrated its ability to impact more than one risk factor in the pathophysiology of type II diabetes mellitus, including: changes in waist circumference, improvement in sensitization and insulin secretion, improved glucose uptake compared to the placebo group, increased hormonal secretion (GLP-1, Leptin, Irisin), decreased low-grade chronic inflammation and reduced hepatobiliary and liver damage.

[0127] The lipid-based composition with micronutrients evaluated in this clinical trial offers a highly effective non-pharmacological therapy in the prevention and/or treatment of pre-diabetes and/or hyperglycemia and to favorably modify the course of these metabolic diseases.
