Since I have started a low-carb diet about two years ago I never limited calories at all. This means I would often eat upwards of 2000 calories/day and sometimes upwards of 2500 calories with the occasional high-workout day with over 3000 calories.
Why am I changing this now?
Several reasons: I found that if my carbs slip up even a little, like they did when I used less expensive but higher carb cashew nuts instead of my usual assortment of hazelnuts, walnuts, almonds, pecans, macadamia nuts I gain body fat and my A1c level does not go down as intended.
I also realized that if I eat a lot less, even of low-carb foods I will consume fewer carbs.
Let's say that about 8% of my calories on a low-carb diet of 2500 calories come from carbs (which is about where I was). That is about 50 grams of carbs/day.
If I only eat 1600 calories daily that drops my carb level to about 32 grams of carbs/day at 8% carbs and to 20 grams of carbs/day at 5% carbs.
Having done this for only about 5 days my weight has dropped by almost 4 lbs (of which some is likely water weight).
But the weight loss is not the important part. I am hoping to speed up the process of lowering my blood sugar levels from an A1c level of 5.8 down to around 5.0
I thought it would be hard for me to limit my calories to 1600 or even 1800 calories/day (assuming little exercise) or 2200 calories/day (assuming lots of exercise) but found that after just a few days my stomach seems to have shrunk to where I feel full much earlier.
This will obviously not always be easy when there are temptations for emotional eating, but even those are very rare now.
I'm hoping to report back in a month or so to see if moving to around 20 grams of carbs/day will make a difference (combined lowering percentage of carbs and lowering number of calories eaten)
I would love to hear from others how much difference about 30 grams of carbs/day make for them.
P.S. If anyone wants to check my math for me, please do, it's not my strength.
