Most people aren't consuming nearly enough protein. The US recommended daily allowance for an adult male is only 56 grams per day, or 0.8 grams per kilogram of body weight.
That is adequate to prevent acute nutritional deficiencies but is way too low for optimal health and athletic performance, especially if you're trying to recover from an injury or build muscle. Older people also need to consume more protein because our digestive systems get worse at taking in protein as we age.
Most of us should be eating at least twice the RDA of protein. And not just any protein, but high quality protein with the right ratios of essential amino acids.
The article is talking about time-of-day-dependent intake of protein affecting total daily calorie intake:
"They then plotted energy intake versus the time of consumption and found that the pattern matched that predicted by the Protein Leverage Hypothesis. Those who consumed lower amounts of protein in their first meal of the day went on to increase their overall food intake in subsequent meals, whereas those who received the recommended amount of protein did not -- and, in fact, declined their food intake throughout the day."
It's like your body is extrapolating the amount of eating necessary for the day to get the needed total amount of protein based on the protein content in your first meal of the day.
You might start to get some kidney toxicity effects if you consume more than about 3 - 4 grams of protein per kilogram of body weight per day. In practice it's going to be difficult to get that much unless you're constantly pounding down supplements.
