It's fine to start, but remember, a diet won't be static for 6 months, your metabolism will speed up and you will have to make adjustments, typically adding in some carbs here and there.
James 1:16-17 ESV
Do not be deceived, my beloved brothers. Every good gift and every perfect gift is from above, coming down from the Father of lights
With God's help...Mens sana in corpore sano
