Proponents of the Paleo diet say it's a much healthier way to eat than the standard American diet, which is often heavy on added sugars and processed foods. Critics say it's too restrictive, banning dairy, wheat and legumes -- food groups that many nutritionists feel should be part of a healthy diet. However, as we noted earlier in this section, veganism and vegetarianism also ban entire food groups and do not come under the same cloud of criticism.


The number one training method the experts turn to again and again for weight loss: interval training. What's that? "Any form of exercise where your heart rate spikes and then comes down repeatedly," says Rilinger. This generally means going hard for a set interval of time (hence the name), followed by active rest, then going hard again. That active recovery portion is key. You need to take it down a notch—OK, several notches—before ramping back up to a higher intensity interval.
Weight Watchers is a household name for the majority of Americans. Why? Because it works. In fact, the U.S News and World Report named this the best weight-loss diet for 2016 in their annual rankings — and with good reason. The balanced program lets you eat what you want, track your choices via a points system, and build a weight loss support network with fellow Weight Watchers' members.
