Nutrition experts working in the University's Food Science Laboratory compared the two dietary regimens, with subjects using the first dietary regimen eating their own food prepared according to the "nutrition pyramid" as a guide. Subjects who adopted the second diet plan ate packaged frozen food as the main meal every day, and configured auxiliary dishes according to the "nutrition pyramid. Both diets contain 1700 calories per day and equal amounts of carbohydrates, protein, and fat.
Before the start of the experiment, both groups reported an average daily intake of about 2400 calories; the subjects weighed about 97kg and had a body mass index (BMI) ranging from 26 to 42, making them overweight or obese.

Rapid freezing causes food to form tiny ice crystals
Quick freezing generally refers to the use of modern freezing technology to reduce the temperature of food to a certain temperature below its freezing point in the shortest possible time, so that all or most of the water contained in it will form reasonable with the external heat of the food. Small ice crystals minimize the liquid moisture necessary for the life activities of microorganisms in food and the biochemical changes of food nutrients, A way to maximize the preservation of the original natural quality of food.
Characteristics of frozen food
General quick-frozen food should have the following five elements (characteristics): freezing should be carried out at 30~18 ℃, and should be completed in about 20 min; The temperature is rapidly reduced to below the temperature of microbial growth activity, which is conducive to inhibiting microbial activity and enzymatic biochemical reactions. The central temperature of frozen food should reach below -18~15 ℃, water in quick-frozen food forms numerous needle-like small ice crystals with a diameter of less than 100 μm to avoid the formation of large particles of ice crystals in the intercellular space. The distribution of ice crystals is similar to that of liquid water in raw materials, causing little damage to cell tissue structure. When food is thawed, the water melted by ice crystals can be quickly absorbed by cells again without juice loss.
The general trend of food quick-freezing technology is low temperature and rapid freezing, and the form of frozen products has also developed from large disk-shaped freezing to monomer rapid freezing. At present, China's quick-freezing device can be roughly divided into strong blowing continuous quick-freezing device, tunnel freezing device, contact freezing device, direct freezing device.
How to lose weight quickly with frozen foods
The volume of food is also one of the factors that affect the weight loss effect of dieters, according to researchers in the United States. Nutritious frozen foods are easy to consume and can be used as a method of controlling food volume.
