I stubbornly think that the best place to start is common sense eating.
Like what surfergirl and Happy said, this means
1. Cutting out almost all processed food (I'll take a slice of homemade chocolate cake over a lean cuisine any day!)
2. Cutting out simple refined carbs (white rice, potato, white bread, high fructose corn syrup)
3. Eating lots of lean proteins
4. Eating very few grains
5. Eating lots of fresh fruits and vegetables
6. Drinking lots of water
7. Reduce portion size
Don't diet, instead nourish your body. Feed it whole, unprocessed foods as much as possible.
I didn't put any numbers on this list, only vague descriptions like "most" or "lots." Play around with what works for you. I need a Diet Coke every other day, some people need a pizza splurge from time to time to keep them sane. 50 g of protein may be "a lot" for me but it's pitiful for someone else. Cutting out "most" grains may be ok, cutting out all grains may be critical for someone else. Play around with what works with your body. I personally have to calorie count on top of these steps I listed, but that's where I am. Maybe you don't.
Dieting should be an act of kindness and love towards your body by providing it the fuel and nutrients it needs to be strong and beautiful, not a repeated self-flagellation of deprivation and sacrifice.
I wish you all the best of luck on your journey!!
