Satiety, fibre, glucomannan and the practical ways to feel full on fewer calories.
Satiety signalling takes 15–20 minutes to register, so eating fast reliably means eating more before fullness arrives.
GLP-1 is a gut hormone released after eating that slows gastric emptying, increases insulin release and reduces appetite.
Drinks produce weaker satiety responses than the same calories in solid form, so they add to intake rather than displacing it.
Psyllium is a soluble fibre with well-replicated effects on cholesterol, bowel regularity and post-meal glucose.
Soluble fibre dissolves and gels, slowing digestion and feeding gut bacteria; insoluble fibre adds bulk and speeds transit.
Glucomannan is a soluble fibre from the konjac root that absorbs water and forms a viscous gel, slowing gastric emptying and increasing
Satiety is produced by stomach stretch, nutrient sensing in the gut, and hormonal signals including GLP-1, PYY and cholecystokinin.
Mindful eating means paying deliberate attention to hunger, taste and fullness rather than eating automatically.
A hunger scale is a one-to-ten self-rating used before and after eating to distinguish physical hunger from habit.
Alcohol supplies about seven calories per gram and simultaneously reduces dietary restraint and sleep quality.
People eat more from larger plates, bowls and packets regardless of hunger, and rarely notice the difference.
Non-nutritive sweeteners reduce sugar and calorie intake but have mixed evidence on appetite and long-term weight outcomes.
Fibre supplements deliver isolated fibre types; food delivers mixed fibres alongside vitamins, minerals and polyphenols.
Snacking is neutral in itself; what matters is whether snacks add to intake or displace part of a meal.
A high-satiety meal combines protein, fibre, water content and enough volume to create genuine stomach distension.
Prickly pear (Opuntia) contains soluble and insoluble fibre plus betalains, and is studied mainly for lipid binding and post-meal gluco
Short sleep raises ghrelin and lowers leptin, increasing hunger and reducing satiety the following day.
Foods that require chewing produce stronger satiety than soft or liquid equivalents with the same calories.
Fermentable fibre is the primary food source for gut bacteria, which produce short-chain fatty acids that influence gut health and appe
Strict food rules increase the psychological value of forbidden foods and raise the chance of rebound eating.
Emotional eating is using food to manage feelings rather than physical hunger, and it is common rather than pathological.
Prescription appetite suppressants have real effects; over-the-counter versions rely mostly on fibre, caffeine or placebo.
A protein-rich breakfast reduces hunger and later-day intake more effectively than the same protein eaten later.
Hunger builds gradually and accepts any food; a craving arrives suddenly and demands one specific food.
Volume eating means choosing foods with low energy density so you can eat a satisfying amount for fewer calories.
