I have been food dieting for more than 10 years. My body fat is 22%.

My diet is  simple. Just eat little food all day especially rice/noodles especially
dinner,I eat very little. (like 2 tablespoon of rice at most)

My bf asked me stop this for 2 weeks, said I m in starvation mode, more difficult to lose fast.
He said after 2 weeks, only start to go back dieting.
Thts more effective in losing fat.

Is it true?
