Like Jo and Jean, I must have a plan and stick to it. I count grams of protein, of fat, and of carbs.

Range of carbs and range of protein is very set, for me.

Range of fat is a bit wider, as it is the least metabolically damaging. But, going too high on fat causes problems, too. That means, for me, feeling sluggish or a bit flush, as well as weight gain. If the fat is too low for a day or two, it is nice to drink some cream, or eat some butter.

A typical day: 60 grams of protein: 35 grams of carbs: 100 - 150 grams of fat.

If I go too low on protein, I get the "cranky, weepy, weak and tired". Too much protein is almost worse for me than a high carb day. Energetic, in a wound-up way, not a pleasant way, especially from beef. (I usually eat veal now. It isn't aged.) Limiting protein helps keep the migraines away.

Too low on carbs, and it feels as though my body is working very, very hard to do something, and can't. Too many carbs means wanting to eat, feeling unwell, and weight gain.

By limiting each group, I am limiting calories.

Sometimes, I total them up. But, I usually just track the grams of P:F:C in my menus.
