Sometimes, when you are in the public eye, you just really need to just be part of the crowd, and look at other people rather than other people look at you.
Around age 40 I put on twenty pounds. I had always had a perfect metabolism. But, my metabolism betrayed me as it does most people, except a very rare few who will always be thin.
It's always good to leave a little space between eating and lying down in bed at the end of the day. The best thing to eat at night in general is protein, fat, and vegetables. For instance, if you're in an Italian restaurant, have chicken piccata with lemon-butter sauce, lots of vegetables, and a big salad. You'll sleep like a baby.
I buy extra virgin olive oil by the case (much less expensive this way) and reach for it several times a day. I use it to marinate and cook my protein, saute my vegetables, and drizzle on my salads.
