In: Obésité, 2014, p. 1–7

Objectives: To study, in obese subjects, the effect of diffuse ultrasound application in the abdominal area combined to muscular work on a vibrating platform. This dual method aims at accelerating the mobilisation of adipose tissue.Methods: 40 sedentary obese women, 18 to 55 years old, with a BMI ≥30 kg/m2 and ≤40 kg/m2 were randomized into 3 groups. 1) A control group (CONTR, n=13), 2) a...

Energy gap in the aetiology of body weight gain and obesity: a challenging concept with a complex evaluation and pitfalls

The concept of energy gap(s) is useful for understanding the consequence of a small daily, weekly, or monthly positive energy balance and the inconspicuous shift in weight gain ultimately leading to overweight and obesity. Energy gap is a dynamic concept: an initial positive energy gap incurred via an increase in energy intake (or a decrease in physical activity) is not constant, may fade out...
