If you're struggling to lose weight, you probably feel like the odds are stacked against you. You're not necessarily wrong.

"There is so much great-tasting food, and it's abundant and in your face all the time. To me it's kind of a miracle that people aren't even heavier than they are," says Dr. Meir Stampfer, a professor of epidemiology and nutrition at the Harvard T.H. Chan School of Public Health. In addition to an abundance of food, most people today also have a far more sedentary lifestyle than past generations. "Even active people who exercise a lot aren't expending the calories their ancestors did," says Dr. Stampfer.

Trying to cut back on calories by drinking diet soda or flavored sparkling water may not help with weight loss, and some research suggest it may actually lead to weight gain. But why, and what are the alternatives?

Diet, exercise, and sleep work together, and all three can have an effect on our daily well-being and longevity. Sleep impacts our eating patterns, and our eating patterns affect our sleep: lack of quality sleep may make people eat more, and make less healthy food choices, but certain foods contain substances that may enhance sleep.

Research we're watching

Widely considered the healthiest diet for your heart, the Mediterranean diet is rich in plant-based foods and features only small amounts of meat and dairy products. But a variation that includes more green plant foods may be even better for you, a small study suggests.

The study included 294 sedentary, moderately obese people whom researchers randomly divided into three groups. Each received different dietary advice: a standard healthy diet, a low-calorie Mediterranean diet, or a "green" Mediterranean diet. Both Mediterranean diet groups included about a quarter-cup of walnuts daily, and poultry and fish replaced beef and lamb.

Ask the doctors

Q. I eat a lot of shellfish and recently developed gout in my knee. Did my diet cause the condition?

A. As you probably know, gout is a painful form of arthritis that occurs when high levels of a waste product called uric acid build up in the body. It can settle into joints, where it forms sharp crystals that can trigger inflammation, redness, and pain. Your diet may have aggravated the condition, but didn't cause it.

Body mass index is commonly used to assess a person’s weight status and health risk, but it does not indicate how much fat a person has or how it is distributed throughout the body — indicators of metabolic health. A recent study analyzed different measures of body shape to determine which are most predictive of premature death.

Losing weight sometimes takes experimentation. If you give a diet your best shot and it doesn't work long term, maybe it wasn't the right one for you, your metabolism, or your situation. Genes, family, your environment — even your friends — influence how, why, what, and how much you eat, so don't get too discouraged or beat yourself up because a diet that "worked for everybody" didn't pay off for you. Try another, keeping in mind that almost any diet will help you shed pounds — at least for a short time.

Here's a look at three common diet approaches.
