Hi. You're going to love this way of eating. I aim for 1300 calories as well. My macros are 10% carb/20% protein and 70% fat. I know some go lower on carbs and make it up with fat. I may try that myself soon.

Hi there,
It also depends how low carb you want to go - are you going for the low-low carb keto inducing way of eating? I believe that's staying under 20g carbs a day.
I started with just cal counting and am also on 1300 a day but over the last few weeks also started tracking my carbs and set my goals so my max is 90g carb a day, but I aim for 50-60g or lower on days where possible! It's really helped me and also doesn't restrict my diet so I can still have some carbs but have to check they're worth it from my daily allowance!
Have a think how low carb you want to be, check the daily carb grams that equates to and then amend % goals to match.

Hi all, note that is 20 NET carbs a day... Don't forget the fiber and how it works with this.
