Losing weight and how much?

Weetbix, eggs and toast sounds like a bland and boring diet. You don't need to rid your diet if everything enjoyable; quite the opposite. You'll have more success if you're eating tasty food you enjoy, that makes you feel good whilst reaching your goals.

Your weight gain is from eating too many calories. People successfully incorporate take away in to their weight loss diets, they just control how much, and make it fit their calories. It can often be calorie dense though, so you might decide its not worth the calorie "spend".

I personally feel the most satisfied and satiated eating quite a lot of protein, loads of vegies (starchy and non starchy - lots of fibre), a sufficient amount of fats (from nuts, meat/fish/eggs, avo, cheese, chocolate, butter and oils), plus some fruit and low fat dairy... I eat very little cereal/grains/bread not because I'm avoiding them, just because I prefer other stuff. Weekends are more flexible and I'll enjoy stuff like Pizza, burgers, pancakes, pasta etc

If you like cola, or fizzy drinks, swap to diet versions.

Toning up comes from losing fat, enabling the muscles to be more defined. That said, I'd probably recommend lifting weights to help retain muscle as you lose. At 10st youre likely to have very little muscle for a 5ft7 man (in my opinion as a 10st 5ft5 woman) so you'd want to keep as much as you can!
