Breakfast is the most important meal of the day, and it’s absolutely necessary to have all three daily meals. Only have fat and oil sparingly while making grains, including sugary cereals and chips, the plurality of your intake. Don’t neglect milk and fresh juice, a vital part of your daily diet. Avoid salt. Binge on grapefruits or cabbage soup to cut calories. And most obviously, stay away from red meat, it is horrible for your health.

Slowly but surely, scientists are debunking the most pervasive of these aforementioned lies about nutrition. We now know, for example, that eating more meals is not healthy. Intermittent fasting, the increasingly popular practice of restricting eating to a period of eight hours per day or less, typically by skipping breakfast, is not only a wildly successful weight loss tool, but it also appears to combat the risk of cancer. In an almost complete reversal of past opinion, leading health authorities are now calling on people to eat more healthy fats. Dietary authorities quietly backtracked on dietary cholesterol, which is now fine to eat. And at long last they are finally calling for a drastic cutback in sugar consumption, which, as it turns out, could be the key to our obesity epidemic.
