Alkaline Fruits to Buy
(Aim for 2–3 servings per day)

• Lemons & limes – Surprisingly alkalizing once digested. Great in water to support hydration and reduce cravings for sugary drinks.
• Berries (strawberries, blueberries, raspberries) – High in fiber and antioxidants with relatively low natural sugar, helping blood sugar stay steadier during weight loss.
• Apples – Provide fiber and crunch for snacks, helping you feel full between meals without a big calorie load.
• Grapefruit & oranges – Vitamin C–rich, hydrating, and refreshing, which can reduce the urge to snack out of boredom.
• Melons (cantaloupe, honeydew, watermelon) – Very hydrating and alkalizing, with a high water content that supports fullness.
• Pears & kiwis – Extra fiber to support digestion and gut health while keeping calories moderate.

Protein-Rich Whole Foods
(1 serving at most meals)

• Skinless chicken or turkey breast – Lean protein to preserve muscle while losing fat, especially important when appetite is reduced on phentermine.
• White fish & salmon – Provide high-quality protein; salmon also includes healthy fats that keep you satisfied and support heart health.
• Eggs – Versatile, portion-controlled protein that works well at breakfast to prevent mid-morning hunger.
• Tofu & tempeh – Plant-based proteins that are naturally alkalizing and easy to season with herbs and spices.
• Greek yogurt (plain, unsweetened) – Offers protein and probiotics; choose plain and add berries instead of sugary flavors.
• Beans & lentils – Provide both protein and fiber, helping you feel full longer on fewer calories.

Fiber-Rich Alkaline Foods
(Include 2–4 servings per day)

• Leafy greens (spinach, kale, romaine, arugula) – Very alkalizing, nutrient-dense, and low in calories, so you can eat a lot for volume.
• Cruciferous veggies (broccoli, cauliflower, Brussels sprouts) – High in fiber and help promote fullness and steady digestion.
• Cucumbers, zucchini & bell peppers – Hydrating, crunchy, and easy to snack on instead of chips or crackers.
• Sweet potatoes – Provide fiber and slow-digesting carbs that keep energy more stable compared to white bread or sugary snacks.
• Quinoa & brown rice – More fiber and nutrients than refined grains, supporting fullness with better blood sugar control.
• Chia seeds & ground flaxseed – Tiny but powerful sources of fiber and healthy fats; a spoonful in yogurt or smoothies helps curb hunger.

Foods & Drinks to Limit While on Phentermine

Sugary Foods & Drinks

• Soda & energy drinks – Highly acidic, packed with sugar, and can cause energy crashes that fight against weight loss.
• Candy, pastries & desserts – Add calories quickly without helping you feel full, making it easier to overeat.
• Flavored coffee drinks – Often loaded with syrups and creamers that quietly add hundreds of calories.

Alcohol

• Beer, wine & liquor – Add empty calories, can interfere with sleep, and may reduce self-control around food. Always ask Dr. Harris about alcohol use while on phentermine.

Acidifying & Highly Processed Foods

• Processed meats (bacon, sausage, deli meats) – Often high in sodium and additives that are more acid-forming and can promote water retention.
• Fried foods & fast food – Heavy, high in unhealthy fats, and can leave you feeling sluggish instead of energized.
• White bread, white pasta & refined crackers – Low in fiber and can spike blood sugar, which may trigger hunger soon after eating.
• Excessive cheese & heavy cream sauces – Dense in calories and more acid-forming; better used lightly rather than as the main part of a meal.

You don’t need to be perfect. The goal is to make most of your choices alkalizing, hydrating, and nutrient-dense so your body can work with phentermine—not against it.
