I'm 46, size 8 and over 5'8. BMI is 19ish.
I walk an hour every day.
I tend not to eat breakfast but if I do fancy it, I'll have toast or porridge with fruit, honey, dates, pistachios, pumpkin seeds etc.
For lunch I'll have soup and a sandwich or salad if at work. On days at home I'll have a sandwich.
For supper I'll eat a big bowl of whole grains with seeds and nuts, lentils, lots of raw or cooked veg, homemade guacamole, houmous, fruit.
I haven't been snacking much recently as I haven't been buying as much treat food as usual (been conscious of keeping the food bill down recently) but I do like to snack on chocolate, crisps and cheese from time to time.
I tend to drink alcohol at weekends, and sometimes during the week.
I don't really think about my weight but if I'm feeling bloated or starting to struggle to fit into my jeans I'll cut back on the treats for a few weeks, and skip a meal most days - usually breakfast.
I wouldn't say that classifies me as obsessive but I do like to fit into my clothes easily so I'm aware of my figure and if I start to put weight on I'll take action quite quickly. But I certainly don't exercise obsessively or starve. Ever.
