As a biochemist, I know how important it is to eat at least 1.5 g of protein per kilo of body weight per day

what it claims

To optimize your fitness and simplify your morning routine, it is recommended to target a daily intake of at least 1.5 g of protein per kilo of body weight, a goal that can be easily supported by adding 20 g of protein powder to your morning coffee.

holds up

A daily intake of 1.5 g of protein per kilo is scientifically consistent for supporting vitality, satiety, and physique on a daily basis.

noli's read

A daily intake of 1.5 g of protein per kilo is scientifically consistent for supporting vitality, satiety, and physique on a daily basis. Indeed, several meta-analyses, such as the one by Morton et al. published in the British Journal of Sports Medicine, confirm that a target between 1.2 and 1.6 g/kg of protein optimizes body composition and general fitness, well above the official minimum intake of 0.8 g/kg. As for the tip of combining protein and coffee, science validates this practical synergy with no loss of nutritional quality. Furthermore, observational studies indicate that the presence of protein slows digestion, which allows for a more gradual release of caffeine and helps avoid the common mid-morning energy crash. While 20 g of powder technically equals the protein content of 3 eggs, whole foods retain the advantage of a natural matrix rich in essential vitamins and lipids, making protein coffee an excellent practical option rather than a perfect substitute.

What the graded evidence says

Evidence
B+
Effect
fat-free mass gain (resistance training) and appetite/satiety — +0.30 kg fat-free mass with protein supplementation (95% CI 0.09-0.52), plateau at ~1.62 g/kg/day; higher protein meals reliably increase satiety vs equal-calorie lower-protein meals
Measured on
healthy training adults; weight-loss and weight-maintenance adults

What’s uncertain

More protein past roughly 1.6 g/kg/day doesn't add much for muscle or fullness. The satiety edge is real but modest, not a magic appetite switch.
