"When you are on the keto diet, you drastically cut your carbs to only 20 per day. That's less than one apple!" said nutritionist Lisa Drayer, a CNN contributor. "The keto diet is just not sustainable over the long term. It doesn't teach you how to acquire healthy eating habits. It's good for a quick fix, but most people I know can hardly give up pasta and bread, let alone beans and fruit."
Every time you chug a bottle of soda, you get hundreds of empty calories. Switching to diet soft drinks is an obvious way to cut calories, but the research is mixed on whether this switch leads to weight loss. Some studies show a short-term benefit. Others find diet soda drinkers gain weight. If you eat or drink more calories than you burn, just switching to diet soda may not do the trick.
Whether your reason for going vegetarian is ethical, environmental, or for health, one thing's for sure: weight loss can be a nice bonus. In fact, in that same study that evaluated vegan, vegetarian, and omnivorous diets, vegetarian diets were almost as effective as vegan—helping people lose 6.3 percent of their body weight compared to 7.5 percent in the vegan group in a half year. Bonus: perfection isn't necessary. Even if you fall off the wagon and break your diet (hey, it happens!) another study found that dieting vegetarians still lost more weight than dieting meat eaters.
See a pattern? Now, I'm not saying these doctors were wrong, exactly. I did need to lose weight. But oddly enough, when I weighed less, the doctors were much more adamant that I lose weight than they are now. When I was actually becoming straight-up obese, it was more of an afterthought. They couldn't ignore my complaints and just say "there's nothing wrong with you," so they added a quick "lose weight."
