First, does being in nutritional ketosis necessarily cause weight loss? For individuals who have experienced fairly rapid weight loss with little effort, their answer is usually a resounding yes! But remember that this is typically based on one person’s experience (or one person and a few of his/her friends). This commonly happens in a person who is relatively insulin sensitive, so that when that individual gets to their new stable (‘maintenance’) weight, they probably did not need to remain in nutritional ketosis—i.e., they could eat a wider range of total daily carbs and still remain weight stable. So in that person’s experience, it looks like nutritional ketosis caused their weight loss and it stopped when they ate enough carbs to go out of nutritional ketosis. In scientific terms, we need to decide if this is a causal relationship, or just an association.
Portion size matters and it’s easy to fall into the habit of overeating and underestimating protein portions. An extra egg for breakfast, an additional ounce of nuts as a snack, or perhaps one more ounce of cheese on your salad–it all adds up. Too much dietary protein can drive down ketone production (Marliss 1978) when consumed in excess of our body’s needs. Read more about this in our deep dive on protein.
Whether you’re falling victim to chub rub, hate hearing the thunderous round of applause your legs give you when you run in shorts, or just don’t like going to battle with your jeans day after day, there are plenty of good reasons to make slimming down your lower half a top priority. They say thick thighs save lives, but strong, toned ones may be the key to a longer, more active life.
