Basic healthy diet?

The Mediterranean diet is widely considered the healthiest- lots of vegetables, but more protein than you've described, and some carbs. You can google it- there are lots of diet plans online.

The Japanese diet is also considered healthy, and they live longer than most westerners. The basis is rice, with small amounts of meat or fish and some vegetables. 

No it doesn't sound familiar but i'd go easy on the fruit. It still contains natural sugars and spikes blood glucose.  The rest of it sounds good.  But i'd have to opt for more meat and fish than that one.

Sounds like something I would say.  Lotsa fruit and vegetables,  not too many potatoes as THAT vegetable is a "bread", pure carbohydrates. Starch in potatoes and bread (all starch) break down into sugar- that is why their calories are high. Snack on carrots, tomatoes, cucumbers,  celery, raisins,  apples, oranges,  peaches, grapes, etc. Fiber, or old-school "roughage", will keep your guts active and clean. Be sensible with sweets. A single small candy ONCE a day, perhaps with evening coffee (just my habit...) won't add a pound. 1 1/2 ounces is enough reward. Water or mineral water, not the sweetened soda water sold as mineral water. ALSO I have read enough negative publicity for diet soda water to never drink it, even if it did NOT have a metallic aftertaste. Avoid diet drinks... 

Fat. I  highly recommend extra virgin olive oil BUTTER, from a cow, not chemicals of oleomargarin. And as little as needed. It is fat, too. Meat.  Chicken, pork, beef- a little that you cook yourself. Spice it yourself.  Otherwise you have no idea what you are eating. 50 to 75 grams... say, less than 3 ounces for each meal. Fish as well 2-3 ounces. 

EXERCISE... now that Y!A is dying, we all can get out and bicycle, run, jog, walk, fall down. Play sports, swim, dance, ride an exercise bike, run a treadmill,etc. Just be active. Won't you join us?
