Supplements

  • Whey protein (25g): pre-workout default, or to hit protein goals
  • Creatine monohydrate (5g/day): 5g daily, any time of day. The single most-researched sport supplement, with 20+ years of data. Not a steroid, not a stimulant — just helps your muscles produce force. Preserves strength on a cut (critical for keeping muscle while losing fat) and has emerging cognitive benefits for men over 40.
  • Vitamin D3 + K2 (2,000-4,000 IU D3 with 100 mcg K2 daily): Low vitamin D is linked to worse body composition, lower testosterone, poorer recovery, and worse sleep. The K2 helps direct calcium to bones rather than arteries. Take with a fat-containing meal.
  • Magnesium glycinate (300-400 mg before bed): Magnesium supports sleep quality, muscle recovery, and insulin sensitivity. Glycinate is the form that doesn't upset your stomach.
  • Omega-3 (2-3g combined EPA/DHA daily): Reduces inflammation and supports recovery.

Non-negotiable rules

  1. Protein at every meal. No exceptions.
  2. Water: 3+ liters/day. Most "hunger" is thirst.
  3. Eat 3 meals, skip snacks. Easier to stay in deficit. If you need a snack, make it protein.
  4. Sleep 7+ hours. Under-slept = higher cortisol = stubborn belly fat. This matters as much as the diet.
  5. One "off-plan" meal per week. Not a cheat day — a meal. Enjoy it, move on.

Daily structure

Wake-up

water + espresso + whey shake

Training is in the morning, sandwiched between a pre-workout whey shake and a carb-inclusive breakfast. Carbs land at breakfast (post-workout) rather than dinner.

Breakfast (post workout)

550-650 kcal, 40-45g protein

The main meal of the morning, eaten right after the shower. 3 eggs or equivalent protein, a healthy fat (avocado, olive oil), and a carb source — berries + oats, a small sweet potato, or steak-and-eggs with sweet potato hash. Insulin sensitivity is highest post-training, so carbs here fuel recovery and glycogen instead of storage. Combined with the pre-workout shake, this puts ~60g of protein in the first two hours of the day.

Supplements: creatine (5g, stirred into water) and vitamin D3 (fat aids absorption, morning timing avoids sleep disruption).

Lunch

600-750 kcal, 45-55g protein

Large leafy greens base, ~6oz cooked protein (chicken, tuna, salmon, or leftover steak), a variety of colourful veg, and a fat source (avocado, olive oil, seeds). A veg-heavy lunch front-loads fiber, keeps the afternoon sharp, and the protein shuts down the 3pm snack spiral.

Afternoon snack (optional)

150-200 kcal, 20g protein

With the pre-workout shake already in the mix, you're usually at ~150-175g protein by the end of lunch without this. Only bring it in if dinner will be late or light on protein. Greek yogurt, hard-boiled eggs, or turkey roll-ups. Skip it if possible.

Dinner

700-850 kcal, 55-60g protein

6-8oz fatty fish, red meat, or bone-in chicken, plus roasted cruciferous or green veg and a healthy fat. Keep it low-carb every night — training was 10+ hours ago, so there's no performance reason for carbs here. Fat and protein at night aid sleep and recovery.

Supplements: omega-3 (largest fat meal = best absorption).

Before bed

magnesium glycinate

Take 30-60 min before lights out. Aids muscle relaxation and sleep depth.

What to eat

Proteins:

  • Eggs
  • Chicken breast, thighs
  • Salmon, tuna, cod
  • Lean beef, pork tenderloin
  • Greek yogurt (plain, unsweetened) — the dairy exception, 2-3x/week
  • Whey protein powder

Fats:

  • Avocado, olive oil, avocado oil
  • Almonds, walnuts, pecans, macadamias
  • Fatty fish
  • Egg yolks

Carbs:

  • Berries, apples, citrus
  • Leafy greens (unlimited)
  • Cruciferous veg (broccoli, cauliflower, Brussels sprouts)
  • Sweet potato, squash
  • Quinoa, lentils, black beans (occasional)
  • Oats (breakfast)

Cut hard:

  • Bread, pasta, rice (rice is fine post-workout occasionally)
  • Croissants — the most delicious thing in the world, however refined flour + butter + sugar is the worst macro combo
  • Bagels — a single one is almost half a day's allowance of carbs in one sitting
  • Donuts — fried refined carbs in seed oil, then glazed; nothing about them survives scrutiny
  • Added sugars, sweetened drinks, sweets of all kinds
  • Seed oils where possible
  • Alcohol — the single biggest fat-loss killer

Recipe bank

All recipes are high-protein, low-carb, low-dairy (with occasional yogurt), and sized to the targets above.

Breakfast

1. The Standard — Eggs, avocado, berries 3 eggs scrambled in olive oil, 1/2 avocado, small handful of blueberries or raspberries. Salt, pepper, chili flakes. Black coffee. Takes 6 minutes. The default — if in doubt, make this.

2. Smoked salmon plate 3-4 oz smoked salmon, 2 hard-boiled eggs, sliced cucumber, capers, lemon, olive oil drizzle. No cooking required — prep the eggs in batches of 6 on Sunday. Great for busy mornings.

3. Greek yogurt power bowl 1 cup full-fat Greek yogurt, 1 scoop whey protein stirred in, 1/4 cup berries, 1 tbsp chopped walnuts, 1 tbsp chia or flax. The 2-3x/week dairy option. ~35g protein and keeps you full until lunch.

4. Steak and eggs 4 oz leftover steak (sliced thin) + 2 eggs any style + sautéed mushrooms in the steak pan. Sounds excessive, is actually perfect — high protein, moderate fat, no carbs. Great on heavy training days.

5. Veggie omelet 3 eggs whisked, cook in olive oil with diced bell pepper, onion, spinach, and 2 oz diced ham or leftover chicken. Top with 1/4 avocado and hot sauce. Hits vegetables early in the day when it's easiest.

Lunch

1. The Default Mixed greens base, 6 oz grilled chicken/salmon/tuna, cherry tomatoes, cucumber, onion, 1/4 avocado. Dressing: olive oil, lemon juice, Dijon, salt.

2. Tuna Niçoise (lazy version) 1 can tuna in olive oil (don't drain), 2 hard-boiled eggs, handful of green beans (microwave 2 min), cherry tomatoes, olives, mixed greens. Dress with the tuna oil + lemon + Dijon. 5 minutes, zero cooking.

3. Chicken + cauliflower rice bowl 6 oz grilled or shredded chicken over microwaved cauliflower rice, topped with salsa, 1/4 avocado, cilantro, lime, and a dollop of Greek yogurt (optional). Burrito bowl energy, none of the carbs.

4. Cold steak salad 5-6 oz sliced leftover steak, arugula, blue cheese crumbles OR feta (small amount), cherry tomatoes, red onion, balsamic vinaigrette.

5. Salmon + greens bowl 4-5 oz canned or leftover salmon, large pile of spinach or kale (massaged with olive oil + lemon so it wilts slightly), cucumber, avocado, hemp seeds, everything bagel seasoning. Omega-3s + fiber + protein in one bowl.

Dinner

1. Sheet-pan salmon + veg 6-8 oz salmon fillet + broccoli and cauliflower florets tossed in olive oil, garlic, lemon zest. 425°F for 15 min. One pan, 20 minutes start to finish. Add a small sweet potato on training days.

2. Steak + roasted Brussels sprouts 6-8 oz ribeye, sirloin, or flank steak seared in cast iron (2-3 min per side, rest 5 min). Brussels sprouts halved, olive oil, salt, roasted at 400°F for 25 min until crispy. Finish sprouts with balsamic glaze or lemon.

3. Chicken thighs + cauliflower mash 4 bone-in skin-on chicken thighs, salt + paprika + garlic powder, roasted at 425°F for 35-40 min. Cauliflower mash: steam a head of cauliflower, blend with olive oil, garlic, salt (skip the butter/cream to stay low-dairy). Satisfying without the carb crash of potatoes.

4. Bison or beef burger, bunless 6-8 oz bison or 85/15 beef patty, cooked in cast iron. Serve over mixed greens with tomato, red onion, pickles, Dijon, and 1/4 avocado instead of a bun. Side of roasted zucchini or asparagus. Feels indulgent, stays on plan.

5. Shrimp stir-fry 8 oz shrimp + mixed stir-fry veg (broccoli, bell pepper, snap peas, bok choy) in avocado oil with ginger, garlic, and coconut aminos or low-sodium soy. Over cauliflower rice. 15 minutes. Great when you're tired and tempted to order in.

Snacks / pre-workout

1. Pre-workout whey shake 1 scoop (~25g) whey protein in water. No blender, no berries — just shake and drink on the walk to the gym. The daily default before training.

2. Greek yogurt + berries + walnuts 1/2 cup full-fat Greek yogurt, 1/4 cup berries, small handful of walnuts, drizzle of honey if pre-workout. The dairy option — use 2-3x/week max.

3. Hard-boiled eggs + almonds 2 hard-boiled eggs + small handful of almonds. Portable, no refrigeration needed for a few hours. Perfect when you're out of the house.

4. Turkey + avocado roll-ups 3-4 slices of quality deli turkey wrapped around avocado slices and cucumber spears. Dip in mustard. No cooking, no mess, hits protein and fats cleanly.

5. Cottage cheese bowl (if tolerated) 1/2 cup cottage cheese, cinnamon, sliced apple or berries, small handful of pumpkin seeds. Slow-digesting protein — best as an evening snack if you're hungry at night.
