I'm a fan of both low carb and keto. I'm also a fan of MFP. My personal experience has been that a calorie deficit is what was most needed for my weight loss. The deficit set by MFP when I plugged in my stats worked for me. I did lower the carb macro to 40% versus 50% (mfp's default) simply because 50% left too much room for cakes, cookies and all the other things I tended to over eat. 10 %...silly, I think, in hind sight but it was effective. In the end, I averaged 35% or 128 grams of carbs per day which was fine for me and I lost my excess weight on the calories suggested by MFP.

I later trialed medically therapeutic keto for reason other than weight management. With that I learned that even lower carb and higher fat was excellent for me for hunger suppression.

I really struggled with being hungry on the macro allocation I first tried in maintenance (the 40% carb/30/30).

I no longer strive for medically therapeutic keto (both low protein and low carb) but do keep my carbs low (about 50 per day) with some higher carb flex days in there. Protein and fats average about 100 each. All equates to about 1500 maintenance calories. That's me.

Plug your stats into MFP. Follow the deficit calorie amount provided. Since you want to eat low carb, reduce the carb amount given by MFP (the 50% default) and spread it over protein and fat. Try it for a month and see what happens with your weight and hunger.

Carb grams under 150 per day generally fit "low carb". Carb grams under 50 per day generally fit "keto". Decide where you want to be and select the % (since MFP uses %) that most closely meets the carb grams you want.

You can always tweak them. Just get started. Good luck and welcome!

There is a keto calculator that I used. You plug in your stats and it'll tell you your macros... Me myself, I'm just trying to keep it below 30g of carbs a day for now. I may get more strict on macros once I get a little more sure of myself.
