Low activity: weight multiplied by 0.8 (lifestyle dominated by sitting posture)
Moderate activity: weight multiplied by 1.3 (daily activity within 1 hour, working, pregnant)
High activity: weight multiplied by 1.8 (high-intensity physical fitness and fitness activities). Some bodybuilders even consume 2-3 grams of protein.
As can be seen from this formula, the more protein, the better. Too much protein is beyond the absorption capacity of human body, and finally it is equivalent to too much heat, which must be stored in the form of fat, which counteracts the effects of fitness and exercise. Simply put, don't eat too much protein if you don't need so much protein.
Protein powder is generally protein-rich powder made of purified soybean protein, casein, whey protein (lacking isoleucine), pea protein, or the combination of the above proteins. Its purpose is to supplement protein for people who lack protein, and it can also be used as a functional additive in food industry.
For healthy people, the lack of protein generally does not occur. Milk, eggs, meat, soybeans, wheat and corn contain all kinds of essential amino acids in sufficient quantities and appropriate proportions. Moreover, the psychological enjoyment and sensory stimulation brought by food can not be replaced by protein powder. Excessive intake of protein is not only a waste, but also harmful to human health.
