Calories and percentages

[Guest guest]

The rule of thumb which says 10 cal per pound is fine. It accounts only

for maintaining the physical body. It can vary greatly when the demands of

physical activity are added. The 10 cal would fit a couch potatoe but a

lumberjack would starve to death. For the latter, I have read in the old

days they would consume up to 10000 cal a day for the intensity of their

activity. Your milage will vary.

When one changes one of the three nutrient groups and seek at the same time

to reach a calorie goal then as one goes down one or both of the others

need to go up to keep calories constant. The usual lower carb approach is

to increase both fat and protein but usually more fat. Recall it contains

about twice the calories of the carbs it replaces so half by measure is

needed.

Another fat consideration is the type of fat. For reasons not important

now go for the less saturated fats to improve diabetic status. If one had

to choose just one fat I would suggest olive oil to replace other more

saturated fats. Increasing the omega3 fat sources, mostly oily fishes or

supplements, has benefit for a diabetic also.
