How to be 70% full? Scientific dietary wisdom

Seventy percent full is a scientific way of eating that can meet the body's needs while avoiding excessive intake. Core methods includeChew slowly, control plate size, and prioritize high-fiber foods, and match it with regular eating times. Secondary techniques involve psychological cues (such as serving rice in small bowls) and keeping a food diary. By combining primary and secondary meals, healthy eating habits can be gradually developed.

Chewing slowly is the key. It takes 15-20 minutes for the brain to receive satiety signals. Slowing down your eating speed can sense satiety in advance. Research by Japanese scholars shows that those who chew each mouthful more than 20 times will reduce their food intake by 15%. It is recommended to put down your mobile phone during meals, focus on the taste of the food, and pair it with soup or warm water to increase your feeling of fullness.

Optimize plate designCan "trick" the brain. Cornell University experiments have shown that using a dinner plate with a diameter of 18-20 cm (instead of 24 cm) can reduce food intake by 22%. At the same time, vegetables occupy half of the plate, protein and staple food occupy 1/4 each, and the portions are naturally controlled through visual proportions. Tableware with contrasting colors can also help reduce appetite.

Choose high-fiber, high-protein foodsExtend the time you feel full. Whole grains such as oats and quinoa have a low glycemic index and can stabilize blood sugar when paired with eggs and beans. Harvard Medical School recommends consuming 25-30 grams of dietary fiber with each meal. For example: 1 bowl of multigrain rice (about 5 grams of fiber) + 1 serving of broccoli (6 grams of fiber) + half a piece of tofu (3 grams of fiber).

Taken together, seven points of full demandA three-pronged approach of behavior, environment and nutrition. From adjusting tableware to changing the order of eating (soup first, vegetables then main food), combined with strength training three times a week to improve metabolism, form a sustainable healthy cycle. The American Heart Association points out that staying 70% full for a long time can reduce the risk of metabolic syndrome by 34%.
