1) DO NOT ask friends for dieting advice. Or at least not in a public, social network sort of place...like a blog or FB, where what ever dumb idea you may have briefly had will forever brand you a crazy person. Be private in your inquiries, very private. Or take the risk of regretting it for all eternity. The person responsible for your health is you. A healthcare professional and one best friend is about all you need...and a way to make calorie-free, gluten-free, sugar-free donuts that taste the same as any normal, cake donut with chocolate frosting...or powdered sugar...
2) FORGET fad dieting. Common sense, statistics and all of my friends on FB will tell you; there is no better way to set yourself up for a re-gain of even more weight. I do not know if pursuing a low-calorie diet for a few weeks is a fad or a necessity. More research required.
3) HAVE A PLAN and stick with it. Premeditating the joy you will get from the food you have planned for each day IS a good thing, and allows for portion control, as you have just obtained all the pleasure you were expecting to get from that little bowl of yogurt. More would just be redundant. Go have a glass of water. Or something.
4) DO have someone with whom you can talk this over. If I blog, it is partially to encourage myself. My husband has incredible self-discipline when it comes to food. He also loves to eat. He is a great sympathizer for me in this journey. (Even though he has never been even 10lbs. overweight in his life.) You need girl friends too!
5) WINE, a word; I find that using this teeny tiny, two-ounce glass for a portion of wine makes life beautiful. If wine should be a forbidden item on my menu, then this little jewel is a treat. That might work for chocolate cake too; I'll have to dig up the kids' old tea set and try.
