Seasonal Vegetables: Spring Cleaning for the Body?

Q. Taught by my grandmother, I practice the time-honored tradition of eating spring greens: dandelions, burdock, stinging nettles, pigweed, lamb’s quarters, plantain, shepherd’s purse, garlic mustard, chickweed, cleavers, and so on. What does modern nutrition have to say about this? Are these greens truly “blood cleansing” or “liver cleansing?

A. In traditional Chinese acupuncture, each season is associated with a different organ and spring is the season of the liver. Many other traditional and alternative healing systems teach that certain plants “cleanse” or “strengthen” the blood or other organs.  You won’t find too much about that in Western nutrition science, though.

Fat-Burning Chili Peppers: The Reality Check

This is the kind of study that the media love:  Researchers from Purdue University report that adding a half teaspoon of cayenne pepper to your meal can reduce your appetite and cause you to burn more calories.  Count on seeing this new “fat-burning tip”  popping up on magazine covers and internet aggregation sites. Before you get too excited, however, it pays to look beyond the headlines.  Continue reading “Fat-Burning Chili Peppers: The Reality Check” >

Low Blood Sugar? Maybe Not.

Q. I have a lot of trouble with low blood sugar.  Any tips for what I should or shouldn’t be eating to help manage this?

A. My first question would be whether low blood sugar (hypoglycemia) is really the problem.

Several years ago, my sister told me she had problems with low blood sugar.  She hadn’t actually been to see a doctor. But she’d noticed that when she felt head-achy, queasy, or shaky (which was fairly often), drinking some juice or eating some crackers usually made her feel better–for a little while. She started carrying little boxes of raisins and animal crackers around in her purse and eating them throughout the day to keep her blood sugar from dipping.

As she told me all of this, I wondered if her “treatment plan” was actually part of the problem.  Continue reading “Low Blood Sugar? Maybe Not.” >

Dear Bob Harper and Editors of Shape Magazine

February 2011 Shape MagazineI recently came across the following weight loss advice from “Biggest Loser” trainer Bob Harper in Shape Magazine (February 2011, page 171):

“Eating first thing revs your calorie burn…If you don’t eat within two hours of waking, your metabolism can slow down to conserve energy.”

Arrggh!  What will it take to put a stake through the heart of this myth-that-will-not-die?  Bob Harper and Shape are not the first to perpetuate this urban legend and I’m sure they won’t be the last.  But, c’mon! A guy of this clout and a magazine of this caliber should do better than repeat well-worn nonsense. They should be a beacon of accuracy in the swirling fog nutrition misinformation.  And so, I’d like to issue…

A Friendly Challenge to Mr. Harper and the Editors of Shape:

If you can produce one shred of evidence or data to support this statement, I will personally treat you all to breakfast–a protein-rich and high fiber breakfast, of course. Continue reading “Dear Bob Harper and Editors of Shape Magazine” >

Ask Monica: Should I Eat More to Burn More?

Q. I started an exercise regime that says I should eat more than I normally do so that my body will burn the calories to lose the weight. The exercises are weight training and cardio and last about 45-60 min per day/ 5 days a week. Is it true that we should to eat more to burn more? I’m have been on the program for 90 days with minimal weight loss.

A.  I wish you’d written about 89 days ago because I’m afraid you’ve been given some bad information.  Simply eating more (or eating more frequently) does not cause your body to burn calories at a faster rate than it otherwise would. Continue reading “Ask Monica: Should I Eat More to Burn More?” >

Does a High Fat Breakfast Burn More Fat?

Hold the skim latte and bring on the butter? High-fat breakfasts are enjoying a comeback in some circles, after a study published in the International Journal of Obesity found that rats who ate a high fat breakfast burned more fat throughout the day than rats who ate a high carbohydrate breakfast.

But the reality on the ground looks a little different. Multiple studies have found that people who eat high fat breakfasts end up eating more calories over the course of the day–almost certainly trumping any increase in the fat-burning metabolism observed in the mouse study.

That’s not to say that a breakfast high in refined carbohydrates (corn flakes, toast, jelly, juice, etc.) is the way to go.  The ideal breakfast for appetite and weight control appears to be one that’s high in both protein and fiber. So bring on the eggs, tofu, cottage cheese, yogurt, oatmeal and other whole grain cereals.

As a bonus, research suggests that this type of low-glycemic breakfast may help you burn more fat during your lunch-time workout.

The Studies:

Time-of-day-dependent dietary fat consumption influences multiple cardiometabolic syndrome parameters in mice.

Energy and macronutrient composition of breakfast affect gastric emptying of lunch and subsequent food intake, satiety and satiation.

The effects of high-carbohydrate vs high-fat breakfasts on feelings of fullness and alertness, and subsequent food intake

Fat oxidation during exercise and satiety during recovery are increased following a low-glycemic index breakfast in sedentary women.
