Horace Fletcher (1849-1919) spread his doctrine to chew each mouthful thoroughly in order to prevent gaining weight. We sought to test this idea by manipulating chewing instructions whilst using electromyography to monitor chewing behaviour. Comparing 35 with 10 chews per mouthful, we showed that higher chewing counts reduced food intake despite increasing chewing speed, and despite doubling meal duration for achieving a subjective reference point for feeling 'comfortably full'. Although limited by a low sample size, our preliminary findings confirm Mr. Fletcher's doctrine, and provide a basis for further research in this area. Outcomes and implications are discussed.

Plant-based alternative proteins-are they nutritionally more advantageous?

Wesley Tay, Rina Quek, Joseph Lim, Bhupinder Kaur, Shalini Ponnalagu, Christiani Jeyakumar Henry

Summary: This study aims to model the replacement of a diet consisting of animal-based proteins with plant-based alternatives in a group of Asians. The results showed that the consumption of plant-based alternatives led to a significant increase in carbohydrates, dietary fiber, sodium, and calcium intake, but a significant decrease in overall energy, protein, and fat intake. The substitution of animal-based proteins with plant-based alternatives may have benefits for bone health and individuals on a caloric restriction diet, but may also have negative effects on individuals with cardiovascular conditions and hypertension, as well as iron deficient populations.

Reasons for meal termination, eating frequency, and typical meal context differ between persons with and without a spinal cord injury

Gary J. Farkas, Paige M. Cunningham, Alicia M. Sneij, John E. Hayes, Mark S. Nash, Arthur S. Berg, David R. Gater, Barbara J. Rolls

Summary: Overeating associated with neurogenic obesity after spinal cord injury (SCI) may be related to how persons with SCI experience satiation, their eating frequency, and the context in which they eat their meals. Those with SCI rely less on physiological satiation cues for meal termination and instead rely more on hedonic cues. There are differences in meal contexts and eating frequency between SCI individuals and controls, with SCI individuals consuming fewer meals but having a higher overall eating frequency due to increased snacking. These factors likely contribute to overeating associated with neurogenic obesity after SCI.
