How to fix your metabolism and lose weight, according to Jennifer Lopez's nutritionist

“A high-protein, low-fat, low-carbohydrate diet will just slow your body down,” warns J.Lo’s nutritionist Haylie Pomroy, author of The Fast Metabolism Diet, a 28-day program designed to heal broken mechanisms in the body.

The plan requires you to eat three different ways a week, for four weeks.

And it claims it could help you lose up to 20 pounds in that time.

“The systematic rotation of targeted foods on specific days and at strategic times will help your body become more efficient at converting food into energy, which is basically what your metabolism is,” she explains.

When on the diet you must

1.Eat 5 times a day: 2 snacks & 3 meals

2.Eat every 3 to 4 hours when awake

3.Eat within 30 minutes of waking

4.Stay on the plan for the full 28 days

5.Stick to the foods allowed in each phase

6.Drink half of your body weight in ounces of water, every day

Day 1&2: Phase 1


“The first thing we need to do is calm the body down and we do so by flooding it with tons of easily accessible nutrients. When we’re under a lot of biological stress such as weight gain, we tend to crave junk food as the quick infusion of sugar is very soothing,” Pomroy tells Metro.

In this phase, you get to eat plenty of natural sugars (found in complex carbohydrates and high-glycemic fruit and vegetables) to stimulate the endorphins in your brain and help pull your body out of an adrenal crisis.

“However, we keep our protein and fat intake very low, as getting energy out of them requires a lot of effort,” she adds.

Food List: Sweet potato, kale, pineapples, cherries, mangos, brown rice, spelt pretzels, corned beef

DAY 3&4: Phase 2


Here, the focus is on lean proteins and high fibre vegetables that will push your metabolism to lay down muscle and access fat for fuel.

“Muscle is built from amino acids, which come from the breakdown of consumed protein. But in order to metabolize protein in the first place, your body needs the nutrients from fat,” says Pomroy.

And assuming we provided very little of it in phase one, the only place to go is your own fat stores.

“Many high protein diets cause your body to become very acidic, which can trigger inflammation, bad digestion and pain. So we balance that with tons of alkalizing vegetables to regulate the body’s PH and make the protein easier to digest,” she adds.

Food List: Asparagus, oysters, chicken, salmon, egg whites, Tabasco, lemons, raw cacao powder.

DAY 5-7: Phase 3


“All week, we’ve been supplying our bodies with nutrients from carbs, green vegetables and lean protein and in the absence of dietary fat, the body has turned to its own stores in order to build muscle. We now make the fats really high because ironically, eating fat after not eating it for a few days makes you burn it like crazy. This is an intense phase in the sense that we’re asking our body to be super efficient at converting fat into fuel,” explains Pomroy.

This is why we then go right back to phase one, where nutrients from food are once again easy to access. Repeat this three-phase cycle for 28 days.

Food List: Avocados, coconut, cranberries, eggs, pistachios, olive oil, pecans, hummus.
