Burn Phase I Diet for Women

Burn Phase One is a very low-calorie diet (about 900 calories per day) that significantly limits the intake of calories, carbohydrates, and fat. This is a temporary diet designed to kick-start rapid fat loss. The idea is to reduce calories to the lowest possible threshold while still eating enough protein to preserve lean muscle mass and taking in enough key micronutrients to avoid deficiency.

On Burn One, you will eat very small meals every 2–3 hours. This program should only be used for up to eight weeks before transitioning back to a sustainable, long-term GRx diet. The medications and supplements accompanying this diet are designed to suppress feelings of hunger and further stimulate fat loss. We don’t recommend that you undertake this program without supportive medications. 

Meal Plan

You must eat every 23 hours. Alternate between a meal and snack every time you eat. It’s important to not skip any of your meals or snacks! Small frequent feedings will keep your metabolism running and prevent you from getting too hungry. 

• 4 oz of lean protein (about the size of a deck of cards) such as chicken, lean beef, turkey, pork loin, or seafood.
• Several servings of raw, steamed, or lightly cooked vegetables.
• Eat 34 of these meals per day.

• You can have anything you want for your snacks as long as you don’t exceed 100 calories. Portion control is key.
Eat fat and protein for your snacks after 6:00 pm. Avoiding carbohydrates at night prevents overeating.
Eat as many non-starchy vegetables as you want. These don’t count towards your 100 calories.
Eat 3 of these snacks per day.

Meal 1 — 4 oz of lean protein with vegetables
Snack 1 — 100 flexible calories with vegetables
Meal 2 — 4 oz of lean protein with vegetables
Snack 2 — 100 flexible calories with vegetables
Meal 3 — 4 oz of lean protein with vegetables
Snack 3 — 100 flexible calories with vegetables
*Meal 4 — If you’re up late, add a fourth meal of 4 oz of lean protein with vegetables

After four weeks on this program, we want you to enjoy a refeed meal. For your refeed, we want you to take 2 hours to eat whatever you want. Indulge and enjoy—you’ve earned it! By introducing a refeed meal every four weeks, you increase leptin levels, keeping your body’s fat-burning process working more efficiently. This will also help to reduce hunger drive and cravings. Mark this down on your calendar and use it as a motivational checkpoint.


Drink half your body weight in ounces per day. For example, if you are 200 pounds, you should drink 100 ounces of water a day. Increasing water intake burns additional calories by boosting your resting metabolism. Water consumption also acts as a natural appetite suppressant. When the stomach senses that it is full, it sends signals to the brain to stop eating.


Non-exercise activity thermogenesis (NEAT) includes the calories expended outside of exercise, eating, and sleeping. Simple tasks such as walking or standing at work help us expend additional calories. Both weight loss and weight maintenance can be made easier by increasing daily NEAT. Try to accumulate 10,000 steps each day by taking brisk 10-minute walks after breakfast, lunch, and dinner.
