Search Results: eating 500 calories

So I found out that some people fast during rest days, there's many types but I'd prefer 5:2 intermediate fasting method. Where for 5 days you eat your targeted calorie amount and the 2 days you eat 500 calories. I'm planning on only eating 500 calories on rest days where I'm not active. My plan is to eat oats (150 calories) and some rice or wraps inc protein (350 cal) for lunch. Then I'll start fasting from 3pm till the next day. Is it a good method? Or am I risking my diet?

I always had trouble gaining weight. Even when I was dorming and eating up to 2,500 calories per day, I stayed a few pounds underweight. Also I don't exercise.

Apparently my dad's sister was similar to me, and she used to eat lard to try to gain weight. Her dad (my grandfather) was apparently naturally very slim. So I suppose it is genetic and comes from my dad's dad.

How about you? Does your body have an inclination to gain weight easily, with difficulty, or neither?
