Those effects look a lot like the ones produced by energy restriction to me.

I didn't think that I was eating much less these days. Maybe because I stopped drinking alcohol back then? Starting to think about weight and doing exercise probably caused me to change my diet without noticing it. I'm still eating ice cream almost every evening and drink half a liter milk-cacao. Today I'm going to eat two soy cutlets with two eggs sunny side up, onions and fries with mayonnaise. In the morning I eat a pan full of oatmeal with milk and a handful of dried dates. In the evening it is often a pizza or bread with cheese and grapes.
