The single easiest, most effective way to lose weight without GLP-1 drugs<\/h1>\n\n\n\n

A simple hack nutritionists wish everyone knew<\/p>\n\n\n\n

We all instinctively know how quickly we eat. But what you may not have realised is that your chewing has real consequences \u2013 for your digestion, waistline and overall health.<\/p>\n\n\n\n

\u201cThere is so much evidence that if you just slow down how fast you eat your food, you reduce energy intake without even realising,\u201d says Prof Sarah Berry, nutrition scientist at King\u2019s College London.<\/p>\n\n\n\n

Indeed, studies have shown that when we slow down our eating by a fifth, we eat between 11<\/a> and 15<\/a> per cent fewer calories.<\/p>\n\n\n\n

On the flipside, people who eat quickly appear to be at higher risk<\/a> of obesity, high blood pressure and type 2 diabetes, compared to slower eaters.<\/p>\n\n\n\n

Simply slowing down at mealtimes could help you eat less, lose weight and support better digestion, all without feeling hungry.<\/p>\n\n\n\n

\u201cTonight, if there\u2019s just one thing you change when you\u2019re having your meal,\u201d says Berry, \u201cslow it down.\u201d<\/p>\n\n\n\n

Why slow eating works<\/h2>\n\n\n\n

Unlike counting calories or cutting carbs, eating slowly is a weight-loss hack that won\u2019t leave you wanting more.<\/p>\n\n\n\n

The reason is simple: it\u2019s your chewing, not just what happens later in the gut, that sets satiety in motion. As you chew, your stomach begins to stretch, and your gut starts releasing fullness hormones \u2013 chemical signals that tell your brain you\u2019ve had enough. <\/p>\n\n\n\n

But these systems aren\u2019t instant.<\/p>\n\n\n\n

\u201cAll those natural processes need time to develop,\u201d Prof Ciar\u00e1n Forde, nutrition scientist at Wageningen University, The Netherlands, whose research focuses on how the senses affect eating behaviour. \u201cThere\u2019s a small lag between eating and the change in chemical signals to the brain.\u201d<\/p>\n\n\n\n

This lag creates a mismatch between how much you\u2019ve eaten and how full you feel. If you eat quickly, intake can easily outpace the body\u2019s satiety controls.<\/p>\n\n\n\n

\u201cThey might arrive long after the event, when you\u2019ve finished your eighteenth cookie, and you\u2019re suddenly ready to burst,\u201d explains Forde. \u201cIt\u2019s too late by then.\u201d<\/p>\n\n\n\n

You can\u2019t speed up these biological signals \u2013 but you can give them time to arrive. Slow your eating, and you allow the body\u2019s natural fullness signals to do their job.<\/p>\n\n\n\n

One of the key players here is the hormone GLP-1 \u2013 the same chemical mimicked by weight-loss drugs such as Ozempic and Wegovy \u2013 which tells the brain we\u2019re full.<\/p>\n\n\n\n

Indeed, research<\/a> led by Waseda University, Japan, found that chewing shredded cabbage released more GLP-1 than when participants gulped it down in pureed form.<\/p>\n\n\n\n

You feel full, so you eat less, without even trying. But it\u2019s not just your appetite that changes.<\/p>\n\n\n\n

In a 2021 study<\/a>, Forde\u2019s team found that slower eaters not only felt fuller, but they had increased insulin responses to their meals, meaning their bodies were better able to process dietary sugar.<\/p>\n\n\n\n

\u201cThe first phase of digestion occurs behind your lips, not down in your stomach,\u201d says Forde. \u201cYou\u2019re priming the body to receive nutrients, so how you chew influences post-meal metabolism and feelings of fullness too.\u201d<\/p>\n\n\n\n
