I decided at the New Year that I wanted to get fit. Not necessarily lose weight, but get fit, and feel better. I work on my feet and made excuses that that was enough. I made excuses that people who watched what they ate weren't enjoying food, and therefore, life.
Once I started swimming and taking an exercise class, it began to influence my eating. I'd look at a can of Coke and think, 'why did I bother swimming 1k to drink pure sugar and calories?' so I'd have water, and if I still wanted a Coke, then I'd have one. Haven't had a Coke in months. No one 'needs' chocolate, biscuits, crisps and sweets. Don't have them in the house.
I LOVE food, but I don't see it as a treat or a reward. Check BBC Good Food or Cook Yourself Thin for good, healthy recipes, really helped me. Cook from scratch, don't be conned by 'low-fat' processed food. Halve the carbs on your plate. I'm not interested in no-carb/zero-sugar, personally. I'm sure if I followed them, my weight-loss would be more extreme, but I'm really happy in my skin.
For the PP who asked about daily intake, on a 'good' day I might have smoked salmon with half-fat creme fraiche on sourdough (one slice, not a sandwich) with black coffee for breakfast, a noodle salad or Mediterranean veg brought from home for lunch, then maybe a small wholewheat pasta meal for dinner (70-100g pasta) Water only, no juice or soft drinks. I know a lot of stricter dieters would shake their heads at that, but it works for me. I cycle to work, try and swim 2-3k a week and do two exercise classes. I don't know what I weigh, don't know how much I've lost, but I have a lot of people ask me about how I lost the weight, and "I ate less and exercised more" always makes people do a double take...
