Thank you for the lovely welcome. I really didn't do anything special, just common sence in that everyone knows the stuff that's healthy and the stuff that isn't. I ate the healthy stuff.
I eat low fat and low carb (but not no fat and no carb). Most meals are low fat protein and vegetables. I rarely eat breakfast and don't snack. I have 7-10 veg portions a day. When I do have carbs they are wholegrain (jumbo oats, wholegrain rice or carbs from veg and pulses) rather than processed, so I don't eat bread, pasta, cakes, biscuits etc. When I do have fats I make sure it's not saturated or trans fats.
We have 4 children, so I cook in big quantities from scratch. I'm a SAHM with my youngest (aged 4) doing mornings at nursery, so have more time than most, but we are low income so I have to be frugal. It helps weight loss that family routine means we eat at the same time every day, week in and week out. Lunch at 12pm, dinner at 5.30pm every day. We all eat the same evening meal. The kids do have bread at lunchtime though.
I also run every day. But I don't link my running to weight loss since I think most weight loss comes from diet. I learnt to run in April by doing C25K and have run almost every day since then. I run for heart health, because my dog loves coming with me, and because I love the personal challenge of it. I'm trying for 300km / 10k per day in RED January.
