NCT07543705
As part of the mandatory annual assessment of physical fitness, soldiers are required to complete a standardized military march. A total of 100 healthy volunteer participants will be recruited from soldiers serving at the Bundeswehr Hospital Ulm. During this march, physiological and metabolic parameters will be assessed. At baseline, anthropometric data and information on medical history, lifestyle, and fitness status will be collected, including a validated questionnaire on physical activity. Blood and urine samples will be obtained to determine routine laboratory and metabolic parameters, and body composition will be assessed using bioelectrical impedance analysis. In addition, selected sensors will be applied to continuously record physiological data. Participants will then complete a 6 km march carrying 15 kg of equipment. After completion of the march, sensors will be removed and additional blood and urine samples will be collected to evaluate metabolic responses to physical exertion, including catecholamine levels.

NCT06700525
Our goal in this study is to further refine StandUPTV, an application designed to reduce SST in adults in our first study (ASU IRB # STUDY00012109), for the StandUPTV Habits program. This program aims to establish a non-sedentary habit triggered by an alert from the StandUPTV application after participants engage in approximately 30 minutes of SST in the evening.
NCT07330388
Adult-onset diabetes is a disease characterized by high blood glucose levels and is one of the leading causes of cardiovascular disease, blindness, end-stage renal failure, and hospitalization. Recent studies support the idea that bacteria found in the gut may play an important role in the development and progression of diabetes. Changes in the gut bacterial environment can affect blood glucose and blood lipids. A increasing number of recent studies have shown that probiotics can alter the gut bacterial environment and reduce blood glucose and blood lipids. The aim of this study is to investigate the effects of probiotics, administered in addition to your current medications, on blood glucose and blood lipids.
NCT07288372
This is a prospective, exploratory, observational study aimed at investigating the mechanisms of glycemic homeostasis by comparing continuous glucose monitoring (CGM) data with results from the oral glucose tolerance test (OGTT). The study plans to enroll approximately 225 participants aged 18-70 years who are at risk for or suspected of having glucose metabolism disorders, but without a prior diagnosis of diabetes. Participants will be equipped with a blinded CGM device for 10-14 days. During this period, they will perform two standardized mixed-meal tolerance tests (MMTT) at home. Subsequently, they will undergo a standard 75g OGTT at the hospital, where blood samples will be collected at multiple time points to measure glucose, insulin, C-peptide, and gastrointestinal hormones (GLP-1, GIP). Based on the 2-hour blood glucose value from the OGTT, participants will be naturally categorized into three groups for comparative analysis: Normal Glucose Tolerance (NGT), Pre-diabetes (Pre-DM), and Newly Diagnosed Type 2 Diabetes (T2DM). The primary objective is to establish a quantitative relationship between CGM-derived parameters (e.g., glycemic variability, time-in-range) after the MMTT and the OGTT diagnostic results. Secondary objectives include assessing the feasibility and correlation between home-based MMTT and standard OGTT, exploring the impact of gastrointestinal hormone responses on daily glucose fluctuations, and investigating the association between postprandial glucose dynamics and vascular reactivity (e.g., postprandial hypotension).

Repeated blood, breath, urine, and muscle biopsies will be taken. In the second arm, participants will consume 1 drink containing 75g glucose, labeled with two stable isotopes of glucose. Periodic blood and breath will be taken over three hours.
NCT06668090
Diabetes mellitus type 2 is associated with low bone turnover and increased risk of bone fractures. Bone mineral density, however, is increased and cannot explain the increased fracture risk per se. The pathophysiology is not completely understood, but the decrease in bone turnover is believed to cause an accumulation of microcracks in bone tissue leading to bone fragility. The decrease in bone turnover may arise directly from insulin resistance or indirectly through formation of advanced glycation end-products. The main aim objective is to investigate how increases in insulin sensitivity following 12 weeks of moderate intensity bike exercise affect biochemical bone turnover markers and biomechanical bone properties in individuals with diabetes mellitus type 2.
NCT07094191
The goal of this clinical trial is to evaluate the acute effects of chicory coffee on metabolism and exercise performance in healthy, moderately active male participants aged 18-25. The main questions it aims to answer are: Does chicory coffee influence glucose, lipid, and energy metabolism after exercise? Does chicory coffee affect physical performance and perceived fatigue levels? Researchers will compare chicory coffee (CC), arabica coffee (AC), and a no-drink control to see if chicory coffee has similar or unique metabolic and performance effects compared to caffeinated coffee or no intervention. Participants will: Consume one of the test beverages (chicory coffee, arabica coffee, or no drink) 45 minutes before performing a shuttle-run test Complete a standardized shuttle-run exercise test Undergo blood sample collection before and after exercise to assess glucose, lactate, LPL, TNF-α, adiponectin, and IL-6 Rate their perceived exertion and record symptoms
NCT02710370
The purpose of this research study is to determine how gastric bypass surgery effects metabolism in obesity and Type 2 Diabetes. One mechanism that has been investigated in animal models is change to the biology of the small intestine (Roux limb) and how glucose and other fuels are metabolized (or how the body digests and uses sugar and other fuels). This study will evaluate the role of the intestine in the beneficial metabolic effects of gastric bypass surgery. It specifically will examine whether the intestine increases its metabolism and its activity, and whether this results in an increase in fuel utilization. Thirty two (32) subjects will be recruited (18 with and 14 without Type 2 Diabetes). At the time of gastric bypass surgery, a small piece of intestine that is usually discarded will be collected. At three time points over the first year after surgery, intestinal samples will be obtained by endoscopy or insertion of a lighted flexible tube through the mouth. Blood samples will be taken at all time points, as well. All samples will undergo comprehensive metabolic analyses. Comparisons will be made between the two groups to understand the metabolic changes over time and if there are differences between the two groups.
NCT01028846
Type 2 diabetes is a chronic condition that affects the ability of the body to regulate glucose (sugar). When glucose levels are low, the liver can make glucose to increase levels in the body. This important process is called endogenous glucose production (EGP). Previous studies suggest that the central nervous system (CNS), including the brain, helps to coordinate this process by communicating with the liver through potassium channels. Control of EGP can be impaired in people with type 2 diabetes, which may contribute to the high levels of glucose seen in these individuals. The purpose of this study is to understand how activating these potassium channels in the control centers of the brain with a medication called diazoxide might inhibit the amount of glucose made by the liver. This is particularly important for people with diabetes who have very high production of glucose, which in turn causes hyperglycemia (high levels of sugar in the blood) that leads to diabetes complications.
NCT06973408
The overall objective of this study is to evaluate the effectiveness of an optimized lifestyle intervention based on dietary advice, behavioral support, and provision of key foods compared to dietary advice with behavioral support or dietary advice alone. The intervention aims to improve nutritional status, metabolic risk factors, and planetary sustainability. A total of 300 participants (150 men and 150 women) who meet all inclusion criteria and none of the exclusion criteria will be recruited. The study will be conducted at the Centre for Lifestyle Intervention at Östra Hospital in Gothenburg, led by researchers from Chalmers University of Technology, University of Gothenburg, and Sahlgrenska University Hospital. Participants will be recruited from two different socioeconomic areas in Gothenburg to examine how dietary interventions function in diverse population groups. The study follows a twelve-week randomized, controlled, parallel intervention design. Participants will be randomized into three groups, each with 100 individuals: Optimized lifestyle intervention group - receiving dietary advice, behavioral support, and provision of key foods. Behavioral support intervention group - receiving dietary advice and behavioral support. Control group - receiving dietary advice according to the SWITCH diet. The SWITCH diet, developed within the EU project SWITCH, is designed to align with European dietary guidelines and promote sustainable and healthy eating habits. It emphasizes whole grains, vegetables, fruits, legumes, and sustainable seafood while limiting processed foods, added sugars, and salt. Throughout the study, participants will undergo clinical assessments at baseline, midpoint (week 7), and endpoint (week 13). Key measurements include anthropometric data, blood pressure, blood glucose, blood lipids, and inflammatory markers. Dietary intake and sustainability aspects of food consumption will also be evaluated. Participants in the intervention groups will receive personalized coaching and access to practical resources, such as meal plans, recipes, and visual educational materials. The primary outcome of the study is the difference in cardiometabolic risk factors (e.g., blood lipids, blood pressure, glucose, insulin resistance markers) between the intervention groups. Secondary outcomes include changes in dietary intake, nutritional status markers, inflammatory markers, and sustainability measures (e.g., CO₂ emissions, land use, biodiversity impact). Additionally, exploratory analyses will investigate associations between diet, lifestyle changes, gut microbiota, and metabolic responses. This study aims to generate valuable insights into the effectiveness of different dietary intervention strategies in real-life Nordic conditions. The results will contribute to the development of evidence-based recommendations for sustainable and health-promoting dietary patterns.
NCT06877208
This is a pilot study in which the investigators will investigate the effect of exogenous glucagon on cerebral glucose metabolism in healthy humans. Participants will participate in either part C or part D of the study, and each participant will participate in three study days. During a study day the participant will receive an intravenous infusion of either glucagon, glucose (in an adjustable rate to match to glucose concentrations achieved with the glucagon infusion) or saline. During each study day an 18F-flouro-deoxy-glucose (FDG) Positron Emission Tomography (PET)/Computed Tomography (CT) scan will be performed to quantify cerebral glucose metabolism during the first part (acute effect) of the glucagon/glucose/saline infusion (part C) or the last part (later effect) of the glucagon/glucose/saline infusion (part D).
NCT02994459
People who are obese often have insulin resistance (inability of insulin to properly control blood sugar) and high blood sugar. However, not all people with obesity have this problem. About one-third of people with obesity have normal sugar metabolism (the way your body uses sugar). Similarly, not all people who are lean are also metabolically healthy and a subset of people who are lean are referred to as metabolically abnormal lean (MAL) or metabolically obese lean because they have the abnormalities in glucose metabolism typically associated with obesity. The reasons why some people with obesity have a problem with blood sugar control and others do not are not entirely clear. It is thought that impaired muscle sugar uptake is the main problem related to high blood sugar in people with obesity. However, adipose tissue (fat tissue) also consumes a substantial amount of blood sugar. Therefore, it is unclear whether muscle or adipose tissue (fat tissue) are primarily responsible for altered blood sugar concentrations in persons with metabolically abnormal obesity (MAO) (those with insulin resistance), compared to those with metabolically normal (healthy) obesity (MNO), or whether "healthy" adipose tissue (fat tissue) expansion in MNO people compared with lean people provides a vessel for blood sugar removal that helps maintain normal blood sugar concentration. Accordingly, the investigators will determine the amount of sugar that is taken up by the body and in the cells of adipose tissue (fat tissue) and muscle by infusing labeled sugar into the blood and looking at its disappearance from blood and appearance in adipose tissue (fat tissue) and muscle. The investigators will also determine how well insulin, a hormone that controls blood sugar, turns on signals that stimulate sugar uptake in fat and muscle cells. These studies will be done after an overnight fast and during an infusion of sugar and insulin (hyperinsulinemic-euglycemic clamp), in sex- and age-matched people who are insulin resistant and insulin sensitive. People with obesity will also be invited to complete a \~10% diet-induced weight loss program and will be studied again after they have achieved the weight loss goal. A group of sex- and age-matched metabolically normal lean participants will serve as control group. An attempt will be made to also study a group of sex- and age-matched metabolically abnormal lean participants.
NCT06860087
Our study aims to explore the influence of dietary chromium supplementation in the form of chromium picolinate, at different doses (200 µg and 400 µg per day), on the health of pregnant women with gestational diabetes. This study will also provide more information on the safety of this type of supplementation during pregnancies complicated by gestational diabetes mellitus. The main questions it aims to answer are: * Does chromium supplementation at various doses in women with gestational diabetes mellitus truly influence their glucido-lipidic metabolism, oxidative/antioxidant balance, and inflammatory state? If so, is it beneficial or detrimental? * If this supplementation is beneficial, which dose is the most appropriate? * Do these types of supplementation have any side effects on the health of the mother and fetus? The participants will take chromium supplements for 6 weeks (supplemented groups) while the control participants will not take them (healthy and diabetic control groups). Chromium-supplemented participants will undergo a medical check-up every 02 weeks to closely monitor their health status and detect any potential side effects at an early stage. Researchers will compare the biochemical profile, oxidative stress status, and inflammation markers between chromium-supplemented and non-supplemented participants to assess the impact of this trace element. Researchers will compare the effects of chromium supplements at different doses with each other.

Investigate the effect and mechanism of time-restricted eating (TRE) on the clinical pregnancy rate in women with PCOS and glucose metabolism disorder via IVF/ ICSI.
NCT06647368
The aim of the study is to develop a non-invasive method for quantifying cerebral glucose metabolism by PET scans in humans. This method will be used in subsequent studies, where the effect of the pancreatic hormone glucagon on cerebral glucose metabolism will be studied. The golden standard for quantifying cerebral glucose metabolism by PET scans is based on arterial blood sampling, which complicates research setup. This study will investigate if image derived measurements instead of arterial blood samples can be used to quantify cerebral glucose metabolism. We will compare the calculations of cerebral glucose metabolism based on arterial blood samples and image derived measurements and hopefully these will correlate. Healthy participants will be included, and each participant will participate in one study day, which includes intravenous administration of radioactively labelled glucose (18-FDG), arterial blood sampling and PET scans.
