Since this plan involves both high-intensity cardio (running/cycling) and Metformin, the nutritional focus needs to be on sustained energy and GI comfort. Metformin can sometimes cause stomach sensitivity, so high-fiber foods are great, but "heavy" or overly greasy meals should be avoided before a run or ride.
Here is a sample weekly structure designed for a man aiming for a – calorie target to hit that 1.7 lb weekly loss.
The "Steady-State" Meal Plan
3 Rules for This Specific Plan
1. The "Metformin Window"
Metformin works best for weight loss when it helps manage post-meal insulin spikes.
Timing: Try to take your dose with your largest meal (usually dinner or lunch).
Avoid: Taking it on an empty stomach right before a long run or ride, as this can lead to nausea or "the trots" (a common runner's woe exacerbated by Metformin).
2. Carb Cycling for Performance
Since you are running and cycling, your body needs glucose.
On Long Ride/Run Days: Increase your complex carbohydrate intake (sweet potatoes, brown rice) by 25%.
On Rest Days: Keep the carbs low and the protein high to encourage the body to burn stored fat.
3. Hydration & Electrolytes
Metformin can affect your kidneys' handling of electrolytes, and running/cycling causes you to sweat them out.
The Formula: Drink at least cups ( liters) of water a day.
The Add-on: Use a sugar-free electrolyte powder (like LMNT or Nuun) during your rides or runs to prevent cramping.
Weekly Shopping List (The Essentials)
