You can say: ‘try dieting’ as well, we do not say ‘do a diet’!

When talking about a decision in the past in this form, the formula is this:
“A few years ago…”
“A few days ago…”
“Yesterday…”
“Last Friday, I decided that I wanted to be a bit healthier, and decided to try a diet.”

This summer, I almost every day hadFor almost every breakfast during this summer, I ate eggs with vegetables for breakfast.

So the word order/language structure here is a bit tricky, here are some more examples:

Examples:
1. For almost the entire year, I wrote in my journal.
2. For almost every dinner this week, I ate lettuce.
3. For almost every day this week, I got up at 6AM.
