Eating only one bowl of powder for breakfast will affect health and indirectly affect weight loss. Losing weight must be based on health. If you sacrifice your health, even if you lose weight, you are likely to lose muscle instead of fat. Such weight loss is not worth the loss.

Take the daily energy requirement of 18-year-old adult male as an example, the three nutrients needed for one day are as follows:

Take indica rice flour as an example, its 100g carbohydrate content is 8 1g, and its protein content is 7.4g, without fat. If you only get the nutritional requirements of the whole breakfast from rice flour, you need at least 350g rice flour to meet the requirements of 25g protein for breakfast. However, the raw-cooked ratio of 350g rice noodles after boiling can reach about 0.3. Obviously, it is unrealistic to cook more than 2kg of rice flour. At present, the rice flour on the market is 75g- 100g. So a bowl of flour for breakfast obviously can't provide enough nutrition. It is suggested that breakfast should be diversified, not just one kind of food, one egg, one glass of milk a day, enough vegetables and proper fruit intake, and coarse grains as the staple food. For example, eat an egg and drink a glass of milk for breakfast, a vegetable and fruit salad, a sweet potato or corn, and a braised pork slice.
