This Is Why You’re Fat: What It Is

When you eat too much, you get fat – right? Not necessarily, says celebrity trainer Jackie Warner in her book This Is Why You’re Fat. It’s not the amount of food you eat that causes weight gain, but eating the wrong foods and how this alters your body chemistry, Warner says.

Based on her experiences with clients, Warner believes that sugar-laden diets, poorly functioning organs, and out-of-whack hormones are the real reasons we get fat and stay fat. She says that eliminating sugar, caffeine, highly processed foods, fatty meats, and alcohol and replacing them with healthy foods can help correct body chemistry, satisfy hunger, and reduce cravings.

Dieters follow a healthy eating plan five days a week, along with a rigorous exercise routine. Then, on weekend "cheat days," they can consume 1,500 calories in a single meal.

Follow the plan’s advice, and you can expect to lose weight at a safe, healthy rate of 4-6 pounds a month.

This Is Why You’re Fat: What You Can Eat

Lean protein, fruits, vegetables, whole grains, and small amounts of healthy fats – all preferably organic -- are the foundation of this high-protein, low-carb diet.

But for the first two weeks of the program, This Is Why You're Fat takes a different tack from most diet plans. Dieters are told to eat as usual, while adding in new and healthy foods.

"I take a very different start-up approach to the plan to get dieters to buy into the non-diet program and let them experience how adding these foods can actually help them eat less of the bad foods," Warner says.

For the first two weeks of the diet, you eat your regular diet plus:

  • 2-3 cups of vegetables
  • 1 cup oatmeal
  • 2 whole fruits
  • 8-ounce whey protein shake
  • 2-3 liters lemon water
  • 2 cups herbal tea

After two weeks, your day might look like this:

  • Breakfast: 2 eggs, 1 cup oatmeal, and 1 cup berries
  • Snack: Protein shake
  • Lunch: 4 ounces lean protein and 1 cup vegetables
  • Snack: 1 cup chopped veggies
  • Dinner: 4 ounces lean protein, 1 cup whole grain, 1 cup vegetables

Dieters are advised to eat frequently, with three meals plus two snacks a day to keep them feeling full. Each weekend, they're allowed two "treat meals," which can include drinks, desserts and other less-than-healthy foods for a maximum of 1,500 calories.

However, during the week, bread, desserts, refined carbs, junk food, coffee, and alcohol are off the menu. Warner says that caffeinated beverages stimulate the adrenal glands to produce more cortisol (stress hormone), and that alcohol can compromise the liver’s ability to metabolize estrogen. She also warns against fluoridated water, acetaminophen, antihistamines, and prescription drugs (which you definitely should not stop taking without consulting your doctor).
