While lighter dinners are often recommended, they should still be balanced and reasonable. Skipping carbohydrates or skipping dinner altogether to control weight is unscientific, unnecessary, and inadvisable.Generally, among the three daily meals: breakfast fuels the morning, lunch fuels the afternoon, and dinner fuels the evening through sleep until the next morning. Thus, dinner is crucial. Neglecting it—by skipping or omitting carbohydrates—may lead to:
1. Energy deficiency causing hypoglycemia, triggering various physical discomforts.
2. Long-term adoption of this practice may disrupt gastrointestinal function, potentially triggering other metabolic disorders, compromising overall health balance, and making weight management goals even more unattainable;
3. When carbohydrates (staple foods) are lacking and energy is derived from fat metabolism, the differing metabolic principles prevent adequate brain tissue fueling. This may induce ketoacidosis, posing health risks;
4.Many who skip dinner experience intense hunger and difficulty falling asleep. Alternatively, delaying dinner until 6 or 7 PM only to give in to late-night snacking before bed actually increases obesity risk. This approach fails to achieve effective weight loss.
Why Skipping Grains at Dinner Won't Help You Lose Weight
Grains are an essential part of every meal.Yet even among our most familiar foods, misconceptions abound.
Staples are high in calories and cause weight gain.
This belief is deeply ingrained, but it's inaccurate. One gram of fat yields 9 kilocalories, while one gram of carbohydrates and one gram of protein each yield 4 kilocalories. Since staples are primarily carbohydrates, claiming they are high in calories is unfounded.
In fact, many staples are low in calories yet provide satiety, actually aiding weight loss—such as oats, red beans, buckwheat, and black rice. However, high-calorie foods are often overlooked, like a single serving of fried chicken or a bowl of fried noodles.In fact, many staple foods are not only low in calories but also provide a sense of fullness, making them beneficial for weight loss. Examples include oats, red beans, buckwheat, and black rice. Conversely, some high-calorie foods are often overlooked. For instance, one chicken wing contains roughly the same calories as 3 ounces of rice, and drinking a 600ml bottle of beer is equivalent to eating 2 ounces of steamed buns.
Eating more whole grains is better than refined grains.
This view also has drawbacks. The essence of consuming staple foods lies in balancing refined and whole grains. For instance, adding millet or red beans when steaming rice, or incorporating oats into white rice porridge. However, excessive consumption of whole grains can impair digestion, increase gastrointestinal burden, and lead to bloating and indigestion.Long-term, excessive consumption may also impair the body's absorption of minerals like calcium and iron, weakening immunity. Therefore, healthy adults should ideally consume only 50–100 grams of whole grains daily, accounting for about one-third of total staple intake. For the elderly and children with underdeveloped digestive systems, who have weaker digestive and absorptive capacities, whole grain intake should be appropriately reduced. Methods like cooking porridge until soft and sticky or grinding whole grains into powder mixed with water can enhance digestion and absorption.
The notion that staple foods only include grains and legumes is somewhat narrow. Broadly speaking, staple foods refer to all grain-based ingredients, encompassing rice, wheat, coarse grains, tubers, and similar items.Therefore, after consuming starchy foods like potatoes, sweet potatoes, or pumpkin, it's advisable to reduce intake of other staple foods. These foods contain higher calories than ordinary vegetables and fruits, and long-term excessive consumption without reducing staple intake can lead to obesity. It's important to note that when preparing these ingredients, avoid deep-frying whenever possible. This not only reduces the formation of carcinogens but also helps control calorie intake.
It's best to avoid staple foods at dinner.
The practice of skipping starchy foods at dinner and consuming only fruits and vegetables—known as the fruit-and-vegetable diet—has gained popularity among young office workers. Surveys indicate that over 60% of female office workers consume insufficient starchy foods daily for weight loss. However, eliminating starchy foods at dinner not only fails to promote weight loss but also compromises health. When the body lacks sufficient carbohydrate supply, it breaks down tissue proteins and fats for energy. The breakdown of tissue proteins can impair organ function;and excessive fat oxidation produces ketone bodies, leading to ketosis or even ketoacidosis. Research indicates that low-carb dieters experience elevated bad cholesterol, increased heart disease risk, and even memory decline. The Chinese Nutrition Society recommends maintaining adequate daily grain intake, typically 250–400 grams for adults.
