Cancer, a very common and sometimes fatal cause of unexplained (idiopathic) weight loss. About one-third of unintentional weight loss cases are secondary to malignancy. Cancers to suspect in patients with unexplained weight loss include gastrointestinal, prostate, hepatobiliary (hepatocellular carcinoma, pancreatic cancer), ovarian, hematologic or lung malignancies.
A relatively new offering, the Nutritarian diet is based on maximizing the amount of healthy vitamins, minerals, and trace nutrients in your food, balancing your hormones, and avoiding toxins. The plan—created by Joel Fuhrman, M.D., author of The End of Dieting—is nutrient-dense, plant-rich, and includes anti-cancer superfoods to help you not just lose weight but live a long, disease-free life. (P.S. Follow these guidelines to make sure you're absorbing all the nutrients from your food.)
If you want to work late at night, think again. When your biorhythms are off, you end up eating more. When you're tired you produce more ghrelin, which triggers cravings for sugar and other fat-building foods. Losing sleep can also alter your hormone production, affecting your cortisol levels that cause insulin sensitivity, prime reasons for belly fat! Getting about 7 hours of sleep a night is one of the best things you can do for your body shaping goals.
There are a plethora of resources for getting started on, or maintaining, the Atkins Diet. In addition to the official Atkins website, with recipes, many free downloads, and a support community, there are thousands of websites built by low carb devotees with additional tips, recipes and encouragement. The book, New Atkins for a New You (Est. $12), is also a good place to start the low carb journey. It's highly rated by users, who say it's a great guide for making a dietary lifestyle change. Some like that the science of low carb eating is well presented, others say they would prefer a more casual approach and more recipes. Others point out that all of the information in the book is available on the Atkins website, free of charge.
How much of a deficit? A 500 calorie a day deficit is sustainable for some while leaning down, but any deficit will do. A 1000 calorie a day deficit is aggressive and difficult to maintain. No matter what, don’t drop your calories below 1000 per day, even if you think it will lead to faster weight loss. You’ll be losing muscle at that point, and sacrificing your health and sanity. Not worth it.
Salt, in moderation, is a good thing—the mineral is necessary for a healthy heart and brain. But too much salt and you’ll retain water, bloating up like a water balloon. Cutting salt is one of the primary ways to drop extra water weight (one reason you may see a big weight loss when starting a new diet!). Move the salt shaker off your table so you’ll get out of the habit of routinely salting all your food. Then if you taste your food and still really want salt you can still stand up and get some. For more weight loss benefits, add these fat-burning foods to your plate to help you lose weight.
