Short-term cardiovascular responses to ingestion of mineral water in healthy non-obese adults: Impact of mineral components

Monnard, Cathriona Rosemary ; Montani, Jean-Pierre ; Grasser, Erik Konrad

In: Journal of Functional Foods, 2020, vol. 71, p. 104017

Background: The role of mineral components in the hemodynamic response to water drinking is still elusive.Methods: We conducted a randomized crossover study in 16 non-obese, healthy subjects (8 women) to investigate cardiovascular responses to water drinks differing in the mineral content. Continuous measurements included beat- to-beat blood pressure, electrocardiography derived RR-intervals,...

How dieting might make some fatter: modeling weight cycling toward obesity from a perspective of body composition autoregulation

Jacquet, Philippe ; Schutz, Yves ; Montani, Jean-Pierre ; Dulloo, Abdul G.

In: International Journal of Obesity, 2020, vol. 44, p. 1243-1253

The notion that dieting makes some people fatter has in the past decade gained considerable interest from both epidemiological predictions and biological plausibility. Several large-scale prospective studies have suggested that dieting to lose weight is associated with future weight gain and obesity, with such predictions being stronger and more consistent among dieters who are in the normal...

Total energy expenditure assessed by doubly labeled water technique and estimates of physical activity in Mauritian children: analysis by gender and ethnicity

Ramuth, Harris ; Schutz, Yves ; Calonne, Julie ; Joonas, Noorjehan ; Dulloo, Abdul G.

In: European Journal of Clinical Nutrition, 2020, vol. 74, no. 3, p. 445–453

In the tropical island of Mauritius, the rise in obesity has accelerated in the past decades, and could be contributed by low physical activity and increased sedentary behavior. The study objectives were to generate the first dataset of total energy expenditure (TEE), to estimate physical activity in Mauritian children, and to explore differences due to gender and ethnicity.Subjects/methods:...

Cardiovascular responses to a glucose drink in young male individuals with overweight/obesity and mild alterations in glucose metabolism, but without impaired glucose tolerance

Monnard, Cathriona R. ; Grasser, Erik Konrad

In: European Journal of Nutrition, 2019, p. -

Little is known about whether mild aberrations in glucose metabolism, which are seen in overweight/obese subjects (OW/OB) without impaired glucose tolerance, affect regulator control elements for blood pressure homeostasis. Methods Hence, we measured in age-matched male subjects with normal weight (n = 16; BMI = 22.4 kg m−2) and OW/OB (n = 11; BMI = 28.6 kg m−2) continuous...

European practical and patient-centred guidelines for adult obesity management in primary care

Durrer Schutz, D. ; Busetto, L. ; Dicker, D. ; Farpour-Lambert, N. ; Pryke, R. ; Toplak, H. ; Widmer, D. ; Yumuk, V. ; Schutz, Yves

In: Obesity Facts, 2019, vol. 12, no. 1, p. 40–66

The first contact for patients with obesity for any medical treatment or other issues is generally with General Practitioners (GPs). Therefore, given the complexity of the disease, continuing GPs’ education on obesity management is essential. This article aims to provide obesity management guidelines specifically tailored to GPs, favouring a practical patient-centred approach. The focus is...

Early and late cardiovascular and metabolic responses to mixed wine: effect of drink temperature

Sarafian, Delphine ; Maufrais, Claire ; Montani, Jean-Pierre

In: Frontiers in Physiology, 2018, vol. 9, p. -

Aim: Red wine is usually ingested as an unmixed drink. However, mixtures of wine with juices and/or sucrose (mixed wine) are becoming more and more popular and could be ingested at either cold or hot temperature. Although the temperature effects on the cardiovascular system have been described for water and tea, with greater energy expenditure (EE) and lower cardiac workload with a colder...

The contribution of Swiss scientists to the assessment of energy metabolism

Montani, Jean-Pierre ; Schutz, Yves ; Dulloo, Abdul G.

In: European Journal of Clinical Nutrition, 2018, vol. 72, no. 5, p. 665–679

Although Switzerland is considered a small country, it has its share in discoveries, inventions and developments for the assessment of energy metabolism. This includes seminal contributions to respiratory and metabolic physiology and to devices for measuring energy expenditure by direct and indirect calorimetry in vivo in humans and small animals (as well as in vitro in organs/tissues), for...

Water ingestion decreases cardiac workload time-dependent in healthy adults with no effect of gender

Monnard, Cathriona R. ; Grasser, Erik Konrad

In: Scientific Reports, 2017, vol. 7, no. 1, p. 7939

Ingestion of water entails a variety of cardiovascular responses. However, the precise effect remains elusive. We aimed to determine in healthy adults the effect of water on cardiac workload and to investigate potential gender differences. We pooled data from two controlled studies where blood pressure (BP) and heart rate (HR) were continuously recorded before and after the ingestion of...

Cardiovascular responses to sugary drinks in humans: galactose presents milder cardiac effects than glucose or fructose

Charrière, Nathalie ; Loonam, Cathriona ; Montani, Jean-Pierre ; Dulloo, Abdul G. ; Grasser, Erik K.

In: European Journal of Nutrition, 2017, vol. 56, no. 6, p. 2105–2113

PurposeThere is increasing interest into the potentially beneficial effects of galactose for obesity and type 2 diabetes management as it is a low-glycemic sugar reported to increase satiety and fat mobilization. However, fructose is also a low-glycemic sugar but with greater blood pressure elevation effects than after glucose ingestion. Therefore, we investigated here the extent to which the...
