The Brown Fat Revolution: How It Works
The technique of cycling carb and protein days is aimed at controlling blood
sugar levels and thus preventing yellow fat from accumulating, Lyons
"When you eat high-fiber, low-glycemic index carbs, you manage insulin [and]
blood sugar levels and prevent overeating, which in turn reduces yellow fat
deposits and increases brown fat," says Lyons.
Lyons says that most women will feel more energetic and less hungry on this
eating plan. He says you can expect to lose 10-12 pounds and shave a few inches
off your waistline and arms during the four
He says the book's detailed exercise program, which uses bungee cords and
light weights, will help build lean muscle, boost metabolism, and, again,
convert yellow fat to brown fat.
While Lyons says that The Brown Fat Revolution eating plan can be
sustained for life, the book does not specifically include a maintenance
The Brown Fat Revolution: What the Experts Say
Washington University nutrition director and American Dietetic Association
past president Connie Diekman, MEd, RD, gives a thumbs-up to the exercise
program in The Brown Fat Revolution. "Exercise is essential, and the
emphasis on core strengthening, along with specific daily plans, pictures and
motivational tips, are the strength of this book," she says.
However, she thinks the diet plan could be difficult to sustain.
She estimates that the eating plan (not including cheat days) provides
approximately 1,200-1,500 calories per day. She notes that it emphasizes
healthy foods that are high in fiber and low in fat. But, she says, there's
little difference between the "carb" and "protein" days -- and both phases
could be inadequate in carbs.
"Depending on your activity level, most women need 100-120 grams of carbs
daily, and if you follow his recommended portions, you may fall short," she
She says someone following the plan might need more supplements than a
multivitamin/mineral, depending on whether their food choices included good
sources of calcium and iron.
Further, she says, snacks following workouts should always include both
carbs and protein to refuel the body, but The Brown Fat Revolution
specifies only carbs.
The Brown Fat Revolution: Food for Thought
Women who prefer to age gracefully without plastic surgery may find The
Brown Fat Revolution can help them fit fitness into their busy lives and
improve their appearance. Middle-aged women stuck on a weight-loss plateau
would benefit from the detailed exercise program and attention to core
Several studies have documented the benefits of brown fat, but there's not
enough research evidence to say that cycling carbs and protein will
increase it, boost your metabolism, and help you lose weight. The cycling of
nutrients and its impact on brown fat also needs more research.
If you're looking for an exercise plan, this book provides great advice. But
if you need a sustainable eating plan to help you lose weight and keep it off
for good, you might want to keep looking.
