Written by Andre Thomas (NASM CPT, Precision Nutrition L2) for adults 40+ who are training in the summer heat. No food groups eliminated, no calorie spreadsheets — just protein targets, carb timing, hydration, and a Sunday-night cook routine that lasts the week.

— Week 1
Foundation — Hit your protein target
First week is calibration. Most adults under-eat protein. Goal: 0.7–1.0 g per pound of bodyweight, distributed across 3–4 meals. Don't change anything else yet — just hit the protein number every day for 7 days. You'll feel it in week 2.
— Sample day
- Breakfast5 whole eggs scrambled, 1 cup wilted spinach, 1 piece sourdough toast — ~35g protein
- Lunch5 oz grilled chicken over big mixed-greens salad, ½ cup quinoa, 2 tbsp measured olive-oil dressing — ~45g protein
- Snack1 cup plain Greek yogurt + ½ cup berries — ~17g protein
- Dinner5 oz grilled salmon, 2 cups roasted summer vegetables, ½ cup roasted sweet potato — ~40g protein
— Week 2
Carb timing — Earn your starches
Carbs are not the enemy. But timing matters when the goal is leaner-by-August. Move most of your starches (rice, sweet potato, sourdough) into the meal RIGHT AFTER your training session. Keep non-training meals protein + non-starchy vegetables.
— Sample day
- Pre-classBlack coffee + a small banana (only if training before 8 AM)
- Post-class5 oz turkey burger, 1 cup roasted sweet potato, 1 cup grilled zucchini — biggest starch portion of the day
- LunchBig chopped salad with 5 oz chicken + ¼ avocado, no starch
- Dinner5 oz grilled fish, 2 cups asparagus, ½ cup brown rice (smaller — already had your big starch post-class)
— Week 3
Hydration + electrolytes
Boston summers eat your sodium and potassium. Underhydration is why your training stalls in July even when you're showing up. Target: ½ your bodyweight in ounces of water daily, MORE on training days. Add a pinch of sea salt and a squeeze of lemon to the first glass of the day.
— Sample day
- Wake up16 oz water + pinch of sea salt + lemon — before coffee
- BreakfastSame protein-forward meal · plus 12 oz iced black coffee
- Pre-class16 oz water in the hour before training
- During classSip plain water — no sugary sports drinks, you're not Tour de France
- Dinner5 oz protein, 2 cups vegetables, ¼ avocado · plus a small handful of olives or pickles for sodium
— Week 4
Maintenance + grilling staples
By week 4 your habits are running on rails. This week is about making the plan repeatable through August. Grill in batches Sunday night — chicken, fish, marinated steak — so weekday meals are 10-minute assemblies. Eat what you cooked.
— Sample day
- Sunday cookGrill 2 lb chicken thighs, 1 lb shrimp, and 2 lb seasoned ground beef. Roast a tray of sweet potatoes and a tray of broccoli.
- Breakfast3 eggs + 4 oz pre-cooked ground beef + sautéed peppers — 5 minutes
- Lunch5 oz grilled chicken thigh, 2 cups grilled vegetables, side of mixed berries — 5 minutes
- Dinner5 oz shrimp + ½ cup quinoa + 1 cup grilled zucchini + lemon — 8 minutes
- Treat1 night/week: a real meal out — protein-forward (steakhouse, sushi, grilled fish). Skip the bread basket, enjoy the rest.
