Keto in a nutshell: keep carbohydrate under 20 g/day, eat a reasonable amount of protein (listen to your body), eat fat to satiety (listen to your body).
If you keep your carbohydrate low, thatâs 90% of this way of eating. The rest is to eat real food to satiety. That means only eating when hungry, stopping eating when no longer hungry, and not eating again until hungry again. Listen to your body.
We have an instinct about how much protein to eat, and fat should be there to replace the calories no longer coming from carbohydrate. We eat low-carb to keep our insulin down, and fat, with its minimal effect on insulin, is a safe source of calories. To know how much to eat, listen to your body.
On a low-carb diet, too much protein is not really a concern, unless you smell ammonia in your sweat or on your breath. But youâll have a very hard time eating that much protein, especially if you listen to your body.
BTW, food percentages are calculated off total calories, and protein contains 4 cal/g, whereas fat contains 9 cal/g. This means that 100 g of protein + 100 g of fat = 31% protein and 69% fat, so âgetting enough fatâ is also hardly a concern.
ETA: if you eat 20 g/day or less of carbohydrate and listen to your body about how much protein and fat to eat, you wonât have to calculate macros or count calories.
