An Overview of Phase 1 of the Fast Metabolism Diet
The Fast Metabolism Diet is a 3-phase nutrition program created by Haylie Pomroy. Phase 1 kicks off the plan by restricting carbohydrates while emphasizing protein and healthy fats. This phase claims to reboot metabolism to burn fat and jumpstart weight loss. A typical Phase 1 diet involves:
Very Low Carbohydrate Intake
Carbs are limited to 0-30 grams per day during Phase 1. Restricting carbs forces the body to burn stored fat for energy instead of glucose. Ketosis may occur.
High Protein Foods
Protein sources like meat, eggs, fish and dairy are encouraged. Protein takes longer to digest, providing steady energy and fuller satiety. Getting adequate protein also helps maintain lean muscle mass.
Moderate Healthy Fats
Fats from plant and animal sources provide energy for the low carb, high protein diet. They also help keep cholesterol levels stable.
Lower Overall Calories
General calorie intake tends to be lower on Phase 1 without the bulk of complex carbs. But calories are not strictly counted as long as carbs stay under 30g.
Benefits of the Fast Metabolism Diet Phase 1
Proponents claim several benefits during the 28 days of Phase 1:
Rapid Weight Loss
Low carb diets spur rapid water weight drops in the first weeks. Stored glycogen depletion and potential ketosis accelerates fat burning as well.
Reduced Hunger
Protein and fats keep hunger at bay better than carby foods. Ketosis may also suppress appetite. Dieters experience fewer cravings.
Boosted Energy
The high protein intake provides steady energy and helps avoid crashes from blood sugar spikes and drops.
Lower Triglycerides
Reducing carbs has been shown to lower blood triglyceride levels for better heart health.
Improved Insulin Sensitivity
Cutting way back on carbs may improve the bodys sensitivity to insulin, which controls blood sugar levels in the body.

FAQs
How much weight can I lose on Phase 1?
Most lose 5-10 lbs in the first 2 weeks. But up to 2 lbs per week of fat loss is reasonable for active adults in Phase 1 ketosis.
What if I feel tired and sluggish on the low carb diet?
Increase healthy fats for energy. Be patient through the "keto flu" for improved clarity in a week or two as your body adapts to ketosis.
Can I drink alcohol on Phase 1?
Alcohol is too high in carbs for Phase 1. An occasional glass of dry wine or ultralight beer won't ruin progress but is not encouraged.
How often can I eat fruit on Phase 1?
Berries and tomatoes are the only Phase 1 fruits. Limit to 1/2 cup berries or 1 small tomato daily to stay under 30g carbs.
