The TLC approach, contained in the 80-page manual “Your Guide to Lowering Your Cholesterol with TLC,” recommends less than 7% of daily calories from saturated fat, less than 200mg of cholesterol, 30 minutes of daily exercise, and drug treatment when necessary. However, critics of the low-fat plan point to its shunning of healthy high-fat plants and its ignoring of the fact that it's calories, and not fat, what determines whether or not a person loses weight.
“The alkaline diet often has a focus on eating lots of fresh produce and unprocessed foods, which could be a good thing,” says Hultin. “However, keep in mind that this is not an evidence-based therapeutic diet. When people take it too far — for instance, drinking baking soda — or become too restrictive or obsessive over food choices, it can definitely turn negative.”
Incorporate a 12-hour fast. Don't panic — most of this fast occurs while you sleep. Restricting your eating to 12 hours a day may help you lose weight, according to one study. You should still eat your recommended daily calories, but limit yourself to only eating during a 12 hour period. So you might eat breakfast at 7am and cut yourself off from eating after 7pm. Though it is not fully understood, this 12-hour fasting period may cause your body to switch from burning food to burning fat.
If you're not up for crunching numbers every day, you can take a more generalized approach. “For some people, it’s knowing, ‘Typically I eat a whole sandwich,’” says Gagliardi. “Now, I’m going to eat half a sandwich at lunch and save the other half for my dinner and cut my calories in half." To get started, consider these 25 ways to cut 500 calories a day.
With this eating style, you’re looking at a lot of menu planning and preparation. A review published in August 2017 in Nutrients suggests the diet could lead to weight loss, but the Academy of Nutrition and Dietetics warns the plan could also cause certain nutrient deficiencies, such as in calcium and vitamin D. (3,4) And, therefore, according to an article published in the January–February 2016 issue of the Royal Australian College of General Practitioners, anyone at risk for osteoporosis should avoid it.

"What I don't like about any commercial diet is that the focus is not on your actual food choices," Hogan said. "It's about calories or points or numbers, and that really takes away from your ability to be in tune with your hunger cues and your fullness cues and what you're really craving. If we become more in tune with those things, we naturally consume how much the body needs. Paying too much attention to numbers takes away from that."
When it comes to the "best" diet for most people, this one consistently ranks at the top of every list. If you can't afford a cruise to the Mediterranean (yet!), at least you can eat like the beautiful, long-living, and famously healthy people from the region. The Mediterranean diet teaches you to eat like a Sardinian, one of the "blue zones" identified by researchers as having a high number of people living past 100—by eating more fish, olive oil, healthy fats, and fresh vegetables. The point is to have not just a longer life but also a healthier and happier one, whether you're trying to lose weight or not. (Really—research shows that you can reap the benefits of the Mediterranean diet without cutting calories.)
If you want to lose weight fast, your best bet is the HMR Program, according to the health experts who rated the diets below for U.S. News. While these diets enable quick weight loss for those with a short-term goal – there's a strong chance you'll drop significant weight within the first 12 months – keep in mind that this is markedly different from long-term weight loss, which is more important for your health.
In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
