Healthy Nutrition Science

One in ten American adults tried intermittent fasting last year, and they may be on to something. The latest research shows that fasting repairs cellular damage, improves the outcomes for chemotherapy patients, and helps with keeping a healthy weight, leading to a resurgence in recent years. Journalist Steve Hendricks’s The Oldest Cure in the World tells the history of fasting—from the ancient world (Jesus treated an epileptic with fasting) to its rediscovery centuries later.

Most of us eat 3 meals a day with a smattering of snacks because we think that’s the normal, healthy way to eat. But when we look at the eating patterns of our distant ancestors, we can see that an intermittent fasting eating pattern is normal—and eating 3 meals a day is not. In The Intermittent Fasting Revolution, prominent neuroscientist Mark Mattson shows that frequent periods of time with little or negligible amounts of food is not only normal but also good for us.

Are you eating enough fat? Yes, fat. Despite what generations of health science has beaten into us over the last 50 years or so, humans thrive on high-fat, low-carb diets.

Keto is the definitive guide to the ketogenic lifestyle.

“Eat less, move more” is incomplete. You can lose weight eating more. How? Through a process known as diet-induced thermogenesis. Diet-induced thermogenesis, the calories burned digesting and absorbing the food you eat, has a greater impact on “calories-out” than exercise. But when you restrict your caloric intake, you restrict diet-induced thermogenesis. Thus, the principle of weight loss is not consuming a very small number of calories - especially when “calories-in” increases “calories-out”.

Through a compassionate lens, Metabolism Repair for Women explores how both eating behavior and energy expenditure are not under conscious control. Instead, they’re subject to the brain’s regulatory mechanism. And if you have metabolic dysfunction (i.e., insulin resistance, hypoglycemia, and/or weight gain), it’s because something is amiss with that regulatory mechanism.
