When someone says, “I’m on a diet“, it means they are following a specific plan of eating in order to lose weight or maintain a certain level of health. It’s similar to saying “I’m watching what I eat” or “I’m trying to eat healthily.”
Here are two examples in sentences:
Example 1:
John decided to lose some weight for his health, so he told his friends, “I’m on a diet, so no more fast food for me.”
Example 2:
Sarah wanted to feel more energetic, so she announced, “I’m on a diet. I’m cutting out sugar and processed foods.”
Now, let’s see two examples in a conversation:
Example 3:
Mike: Emma, would you like a slice of pizza?
Emma: Thanks, Mike, but I’m on a diet. I’m trying to eat more fruits and vegetables instead.
Example 4:
Lisa: Hey Sarah, want to grab a cupcake from the bakery?
Sarah: I’d love to, Lisa, but I’m on a diet. I’m avoiding sweets for a while.
So, when you say, “I’m on a diet,” you’re letting people know that you’re making specific food choices to reach a personal health goal. It might be about losing weight, improving overall health, or managing a specific condition.
