Eva P. — 4-Week Aggressive Fat Loss Plan
Female · 46 · 5'0" · Tirzepatide 5mg Weekly · Target: Low-to-Mid 160s · Coach Larry Williams Jr.
📊 Goal Reality Check
Eva, let me be direct with you about the numbers because that's how I operate. Your 12-week progress is exceptional — borderline textbook. You lost 16.1 lbs, of which 15.7 lbs was pure fat and only 0.4 lbs was lean mass. That's a 97.5% fat-to-total-weight ratio. Most people lose 20-30% of their weight from muscle. You barely touched yours. Tirzepatide is working, and whoever has been coaching you has your protein right.
Now — losing 4-5% body fat in 4 weeks is extremely aggressive. Your first 12 weeks netted 5% BF, but that was over three months. Here's what the math actually says: to drop 4-5% BF in 4 weeks while holding your LBM at 107.8 lbs, you'd need to lose 11-15 lbs of fat in 28 days. Even at your best, that's 2.75-3.75 lbs/week of pure fat — which requires a ~1,300-1,800 cal daily deficit. That's not realistic without causing significant muscle loss.
What IS achievable: At 1,400 cal + Tirzepatide 5mg creating a combined ~1,100-1,200 cal effective deficit, you're looking at ~2.2-2.5 lbs/week — landing you at 164-167 lbs (the 160s ✓) with a BF% reduction of 3-4%. We're going to hit the 160s. The 4-5% BF goal is the ceiling we'll push toward, not the floor. If the scale cooperates, we'll get there. If not, we're still winning.
📈 InBody 570 Progress — May 5, 2026 → August 1, 2026 (87 Days)
| Metric | May 5, 2026 | Aug 1, 2026 | Change | Assessment |
|---|
| Body Weight | 190.6 lbs | 174.5 lbs | −16.1 lbs | Excellent pace — ~1.34 lbs/week average |
| Body Fat Mass | 82.4 lbs | 66.7 lbs | −15.7 lbs | 97.5% of weight lost = pure fat ✓ |
| Lean Body Mass | 108.2 lbs | 107.8 lbs | −0.4 lbs | Near-perfect LBM preservation — exceptional |
| Body Fat % | 43.2% | 38.2% | −5.0% | 5% BF in 12 weeks — real, verifiable progress |
| Skeletal Muscle Mass | 59.3 lbs | 59.7 lbs | +0.4 lbs | Actually GAINED muscle while losing fat — recomp |
| InBody BMR | 1,431 kcal | 1,426 kcal | −5 kcal | BMR barely dropped despite 16 lbs lost — LBM held |
| Visceral Fat Level | Level 16 ⚠️ | Level 13 | −3 levels | Significant VF reduction; goal is Level <10 by Week 8 |
| ECW/TBW | 0.387 ⚠️ | 0.379 | −0.008 | Improved hydration balance; still at upper border of normal (≤0.380) |
| SMI | 8.6 kg/m² | 8.3 kg/m² | −0.3 | Slight drop (normal as weight decreases) — watch as fat loss continues |
The LBM story is the headline. You lost 15.7 lbs of fat and only 0.4 lbs of muscle over 12 weeks. Research on well-controlled fat loss shows the average person loses 20-30% of their weight from LBM. Eva lost less than 3%. This is what high protein + Tirzepatide looks like when executed correctly. The plan going forward builds on this.
🔢 Calorie Math — Katch-McArdle (InBody 570 Verified)
| Calculation | Value | Notes |
|---|
| Lean Body Mass (LBM) | 107.8 lbs / 48.9 kg | Direct from InBody 570 — 08.01.2026 |
| BMR — Katch-McArdle | 1,426 kcal | 370 + (21.6 × 48.9) = 1,426 ✓ matches InBody verified BMR |
| Activity Multiplier | Moderately Active × 1.55 | 3–5 training days/week assumed — adjust if training volume differs |
| TDEE | 2,210 kcal/day | 1,426 × 1.55 = 2,210 total daily energy expenditure |
| Diet-Based Deficit | −810 cal/day | From food intake at 1,400 cal target |
| Tirzepatide 5mg Effect | + ~300–450 cal suppression | Dual GIP/GLP-1 adds natural appetite suppression on top of diet |
| Total Effective Deficit | ~1,110–1,260 cal/day | Combined diet + medication effect |
| CALORIE TARGET | 1,400 cal/day | ~37% below TDEE — aggressive but supported by Tirzepatide |
Critical note on the BMR floor: At 1,400 cal you're below BMR (1,426). This is intentional only because Tirzepatide actively helps preserve lean mass through hormonal signaling — something a pure caloric restriction can't do. Without Tirzepatide, I would not go below BMR. With it, 1,400 is the aggressive floor. Do not go lower. If appetite drops further due to the medication, use protein shakes to hit your numbers, not to skip them.

| Macro | Daily Target | Calories | % Total | Per Meal (4×) | Basis |

| PROTEIN | 140 g | 560 cal | 40% | ~35 g | ~1.3g per lb LBM — aggressive for LBM preservation on deep cut |
| CARBS | 98 g | 392 cal | 28% | ~24 g | Training fuel; prioritized around workouts; flexible on rest days |
| FAT | 50 g | 450 cal | 32% | ~12 g | Hormone production; satiety; critical for females at 46 (perimenopause) |
| TOTAL | — | 1,402 cal | 100% | ~350 cal | Verified: (140×4) + (98×4) + (50×9) = 560+392+450 = 1,402 ✓ |
Why 40% protein at only 1,400 cal? At a deficit this deep, protein's primary job shifts from building muscle to sparing it. You're not building right now — you're defending. 140g protein on 1,400 calories is aggressive, and that's exactly the point. It's what your LBM numbers have earned: they stayed at 107.8 lbs over 87 days. We're going to protect that going into the next 4 weeks.
Fat matters more than you think at 46. Estrogen production shifts significantly in perimenopause, and dietary fat is a key precursor for sex hormone synthesis. Dropping fat too low crashes estrogen, tanks libido, destroys sleep quality, and stalls fat loss. The 50g fat floor is non-negotiable.

Scale note — creatine will add 2-4 lbs of intramuscular water in Week 1. This is not fat. It is not failure. It is creatine doing its job (filling your muscle cells with water and ATP substrate). If you start creatine and the scale goes up 2 lbs in Week 1, celebrate — that's your muscles getting better at retaining energy. Fat loss is still happening underneath it. Judge by the 4-week InBody, not Week 1 scale weight.
🏋️ Training Day Carb Protocol
Rest Day (1-2×/wk)
68g
~1,250 cal
Low activity — reduce carbs by 30g
Pull carbs from Meal 2 (skip rice). Keep protein and fat identical. Minimum 140g protein even on rest days.
Cardio Day (1-2×/wk)
98g
Base 1,400 cal
Zone 2 — 30-40 min treadmill, bike, or elliptical
Base plan as written. Cardio at this stage is primarily for cardiovascular health and visceral fat reduction — not primarily calorie burn.
Strength Day +25g carbs (3-4×/wk)
123g
~1,500 cal
30 min before training: add banana or rice cake
Strength training in a deficit requires fuel. The +25g pre-workout prevents cortisol-driven muscle breakdown and keeps training output high — which is what maintains that 107.8 lbs of LBM.
Progressive overload doesn't stop because you're cutting. If the weights on the bar are going down week over week, you're losing muscle. Your goal in every session: maintain or improve. If you can't match last week's weight, something else is wrong — sleep, food timing, hydration, or calorie distribution. We diagnose it, we don't just accept it.
💊 Tirzepatide 5mg — Optimization Protocol
Tirzepatide at 5mg is your biggest lever right now. You've already been on it and the InBody proves it's working — 15.7 lbs of fat gone, LBM maintained. At 5mg, you're approaching the dose where appetite suppression is near-peak for most patients. The next 4 weeks are the phase where this medication is working hardest. Your job is to not let it work against you.
| Protocol Point | Why It Matters at 5mg |
|---|
| Protein FIRST at every meal | At 5mg, Tirzepatide may cause you to feel full after 60-70% of a meal. Always eat protein first so if you stop early, you've already gotten your most critical macro. |
| Eat 4 meals — no skipping | Tirzepatide can suppress appetite so aggressively that people go 5-6 hours without eating and miss protein windows. This causes muscle loss. Structured meal timing prevents it. |
| Never skip protein to manage nausea | If nauseous, switch to a protein shake instead of skipping. 25-30g of whey in water is easier on GI than solid food and still hits your protein target. |
| Minimum floor: 120g protein / 1,100 cal | If appetite drops aggressively, this is your absolute floor. Below 1,100 cal or below 120g protein = muscle loss. Non-negotiable. |
| 1 gallon water daily | Tirzepatide increases urinary sodium and potassium excretion. Dehydration causes fatigue that mimics hunger and crashes training performance. Electrolytes required daily. |
| Injection timing optimization | Inject on a day you don't have a big meal planned (like a Sunday before a normal week). If injection causes significant nausea, time it for evening to sleep through side effects. |
| Weight loss pace vs. medication dose | If losing <1 lb/week consistently, discuss dose escalation with your prescriber. If losing >3 lbs/week on the scale, increase protein and check calories aren't dropping too low. |

These are templates, not rigid scripts. Swap proteins within the same weight/protein range (salmon for chicken, egg whites for turkey). The macros per meal below are targets — use a tracker like MyFitnessPal to dial in your specific brands and portions. The non-negotiable: protein hits 140g every day, no exceptions.
Meal 1
7:00 AM
Protein Yogurt Bowl
~310 cal
P: 42g
C: 26g
F: 6g
1 cup Fage 0% Greek yogurt — 17g protein, 6g carbs, 90 cal
1 scoop vanilla whey protein, mixed into yogurt — 25g protein, 3g C, 120 cal
½ cup frozen berries (thawed) — 9g carbs, 35 cal
1 tbsp chia seeds — 2g P, 5g C, 4g F, 58 cal
Black coffee — appetite support, zero calories; add stevia if needed
Meal 2

Lean Protein Power Bowl
~420 cal
P: 40g
C: 38g
F: 10g
5 oz grilled chicken breast (batch cooked) — 33g P, 155 cal
½ cup cooked brown rice — 22g C, 108 cal
2 cups broccoli + peppers (steamed or roasted) — 12g C, 60 cal
1 tsp olive oil + lemon + garlic — 4g F, 40 cal
½ cup cottage cheese 2% on the side — 7g P, 70 cal (hits protein + satiety)
Meal 3
3:30 PM
Pre-Workout Protein + Fuel
~220 cal
P: 27g
C: 22g
F: 3g
1 scoop whey protein in water — 25g P, 120 cal (low volume on Tirzepatide)
1 medium apple — 20g C, 80 cal (quick carb fuel if training within 60 min)
On rest days: swap apple for ½ cup berries (10g C less). Protein shake stays.
Creatine 5g mixed in shake — tasteless, adds 0 calories
Meal 4
7:00 PM
Hormone-Supporting Dinner
~450 cal
P: 35g
C: 18g
F: 22g
5 oz salmon fillet (2-3× week) OR 5 oz chicken thigh (skin removed) — 28-32g P, 10-14g F
½ cup roasted sweet potato or ½ cup quinoa — 20-25g C, 90-110 cal
2+ cups leafy greens + zucchini + cucumber (unlimited — fills the plate)
1.5 tsp EVOO dressing + lemon + herbs — 7g F, 60 cal
Magnesium Glycinate 400mg + Vitamin D3 taken with this meal (fat-soluble vitamins)
Day totals (approx): ~1,400 cal | 144g P | 104g C | 41g F — within target range. Variance is expected; track the 7-day average, not single days. If Tirzepatide causes you to eat less on one day, compensate by making sure the following day still hits 140g protein.
🗓 Weeks 3–4 Adjustments — Tirzepatide Fully Active
By Week 3, Tirzepatide at 5mg is producing near-maximal appetite suppression for most patients. Food noise is quieter. Meals feel less important. This is where people tend to undereat — and where you are most vulnerable to muscle loss if protein slips. The Weeks 3-4 strategy is all about protein-first eating in a lower-volume format.
| Meal | Week 1-2 Format | Week 3-4 Adaptation |
|---|
| Meal 1 (7am) | Full yogurt bowl + whey | If not hungry: whey + collagen shake (40g P, 150 cal, 5 min) — protein first, always |
| Meal 2 (12pm) | Full chicken + rice bowl | Eat chicken/protein FIRST. If full before finishing rice — stop the rice, not the chicken |
| Meal 3 (3:30pm) | Shake + apple | If appetite is low, skip the apple. Never skip the protein shake. |
| Meal 4 (7pm) | Full salmon + potato dinner | Reduce starch to ¼ cup if not hungry. Double the vegetables. Protein stays. |
| Minimum floor | 1,400 cal / 140g P | If very suppressed: 1,200 cal / 120g P is absolute floor — below this, call Coach |
Warning sign: If you're going more than 5 hours between eating and don't feel hungry at all — that's Tirzepatide doing its job, but it's also when muscle catabolism risk is highest. Set a phone alarm if needed. Eating is now a performance behavior, not an appetite-driven one.
💊 Evidence-Based Supplement Stack
My philosophy on supplements: They supplement a good diet and training program. They don't replace either. The supplements below have peer-reviewed evidence supporting their use in this specific context. I'm not listing anything I wouldn't take myself or prescribe to a serious client. Everything on this list has a clear mechanism and documented effect size.
Tier 1 — Non-Negotiable (Take These Daily)
Creatine Monohydrate
Most studied supplement in existence. In a caloric deficit, creatine monohydrate has been shown to reduce lean mass loss, maintain strength, and improve cognitive function. At 46, creatine also supports bone density. Note: may cause 2-4 lbs of scale gain from intramuscular water in Week 1. This is normal and desirable.
5g/day
any time
Whey Protein Isolate
Not optional at 1,400 cal. Getting 140g protein from food alone is extremely difficult at this intake level. Use 1-2 scoops/day to reliably hit your protein target. Isolate preferred: faster absorption, lower lactose, cleaner on GI (important on Tirzepatide).
1-2 scoops
as needed
Omega-3 Fish Oil (EPA+DHA)
Strong evidence for reducing inflammation, improving insulin sensitivity, supporting cardiovascular health, and reducing visceral fat. Your VF level is at 13 — omega-3 supplementation specifically targets visceral adipose tissue. Also improves mood and sleep quality on a caloric deficit.
3g EPA+DHA
with meals
Vitamin D3 + K2 (MK-7)
80%+ of Americans are Vitamin D insufficient. At 46, declining estrogen reduces Vitamin D conversion efficiency. D3 supports fat metabolism, immune function, mood, muscle protein synthesis, and bone density. K2 (MK-7) ensures calcium goes to bones, not arteries. Non-negotiable at this life stage.
3,000-5,000 IU D3
100mcg K2
Magnesium Glycinate
Magnesium is involved in 300+ enzymatic reactions. On a caloric deficit with Tirzepatide, magnesium depletion accelerates. Deficiency = poor sleep, muscle cramps, elevated cortisol, and impaired insulin sensitivity. Glycinate form: highest absorption, no GI upset, best sleep improvement. Take before bed — dramatically improves deep sleep quality.
400mg
before bed
Tier 2 — Highly Recommended (Strong Benefit for This Specific Context)
Electrolyte Supplement
Tirzepatide increases natriuresis (sodium excretion through urine). At 1,400 cal with a GLP-1/GIP agonist, electrolyte depletion is rapid and predictable. Symptoms: fatigue, brain fog, muscle cramps, poor performance in the gym. LMNT, Liquid IV, or similar — sodium + potassium + magnesium daily. Not optional on this medication.
1 packet/day
in water
Psyllium Husk
Tirzepatide slows GI motility. Constipation is the most common complaint among patients. Psyllium husk (soluble fiber) prevents this, adds 0 digestible calories, creates significant satiety, and supports healthy gut microbiome. At 1,400 cal, fiber intake is likely insufficient from food alone — psyllium fills this gap.
5-10g
with water 2×/day
Quality Multivitamin
At 1,400 cal, hitting micronutrient RDAs from food alone is nearly impossible without perfect diet design. A broad-spectrum multivitamin provides nutritional insurance. Not a substitute for quality food — fills micronutrient gaps that inevitably appear at this calorie level. Choose food-based or whole-food blends over synthetic.
1 serving
with Meal 2
Zinc (Bisglycinate)
Zinc deficiency is common in females eating restricted diets. Zinc supports testosterone production (yes, females need testosterone too), thyroid function, immune health, and wound healing. Low zinc = suppressed metabolic rate and impaired recovery. Take with dinner (not with calcium — competes for absorption).
15-25mg
with Meal 4
Tier 3 — Beneficial (Situationally Useful — Not Required)
Collagen Peptides + Vitamin C
At 46, with 16 lbs already lost and more coming, skin elasticity is a real concern. Collagen peptides taken with Vitamin C (which is required for collagen synthesis) have modest but real evidence for supporting skin health and connective tissue during significant fat loss. Not for muscle building — that's whey's job. For skin, tendons, and joints.
15-20g
+ 500mg Vit C
Ashwagandha (KSM-66)
At 1,400 cal and high training volume, cortisol rises. Chronically elevated cortisol directly inhibits fat loss and promotes muscle breakdown. Ashwagandha KSM-66 (the form with actual evidence) has shown in RCTs to reduce cortisol by 25-30%, improve sleep quality, and reduce perceived stress. Useful if sleep quality is an issue or stress is high.
600mg
before bed
Caffeine (from coffee/tea)
Natural caffeine before training provides real, research-backed fat oxidation and performance benefits. Avoid supplements here — use black coffee or unsweetened tea. Not a thermogenic — a performance aid. Cap at 200-300mg/day. Avoid after 2pm to protect sleep quality (which is when you release GH and repair muscle).
1-2 cups
pre-workout only
📅 Suggested Weekly Structure
| Day | Activity | Calories | Carbs | Focus |
|---|
| Monday | Run — 2–4 miles (easy-moderate pace) | 1,400 cal | 98g (base) | Fat-burning pace; aerobic base for DEKA FIT |
| Tuesday | Full Body Strength — 6:00 AM w/ Coach Larry | ~1,500 cal | 123g (+25g) | Compound movements; progressive overload; eat pre-workout by 5:15 AM |
| Wednesday | Run — 2–4 miles (easy-moderate pace) | 1,400 cal | 98g (base) | Active recovery run; fat oxidation; DEKA run prep |
| Thursday | Full Body Strength — 6:00 AM w/ Coach Larry | ~1,500 cal | 123g (+25g) | Compound movements; progressive overload; eat pre-workout by 5:15 AM |
| Friday | Run — 2–4 miles (easy-moderate pace) | 1,400 cal | 98g (base) | Longer effort on this day preferred; builds DEKA endurance base |
| Saturday | Full Body Strength — 6:00 AM w/ Coach Larry | ~1,500 cal | 123g (+25g) | Week's final strength session; incorporate DEKA-style movements |
| Sunday | Run — 2–4 miles (easy) + Meal prep | 1,400 cal | 98g (base) | Easy recovery run; batch cook proteins for the week |
Weekly calorie average: (1,500 × 3 strength days) + (1,400 × 4 run days) = 4,500 + 5,600 = 10,100 ÷ 7 = ~1,443 cal/day average. The daily variation is strategic — strength days get the extra 25g carbs to fuel the 6 AM sessions with Coach Larry; run days stay at base because easy-to-moderate running runs primarily on fat, not glycogen. No rest days on this schedule means no calorie reduction days either.
📏 Week 4 InBody Re-Scan Targets
| Metric | Current (Aug 1) | Conservative Goal | Aggressive Goal |
|---|
| Body Weight | 174.5 lbs | 167-169 lbs | 163-165 lbs |
| Body Fat % | 38.2% | 35.5-36.5% | 33.5-34.5% |
| Body Fat Mass | 66.7 lbs | 59-62 lbs | 54-57 lbs |
| Lean Body Mass | 107.8 lbs | ≥107.0 lbs ✓ | ≥107.0 lbs ✓ |
| Visceral Fat Level | Level 13 | Level 11-12 | Level 10-11 |

| Skeletal Muscle Mass | 59.7 lbs | ≥59.3 lbs ✓ | ≥59.5 lbs ✓ |
The most important number at Week 4 is LBM, not scale weight. If you lose 10 lbs but drop 2 lbs of LBM, that's a worse outcome than losing 7 lbs with zero LBM loss. Preserve the muscle. The fat will keep coming off. LBM is what determines your metabolic rate, body composition percentage, and how you look at goal weight. Protect it at all costs.
Eva — the data on your two InBody scans is genuinely impressive. You lost 15.7 lbs of fat in 87 days and held onto 107.4 of your 108.2 lbs of lean mass. That's not luck. That's execution. Whoever designed your first phase built it right, and your body responded exactly as it should.
Here's the truth about the next 4 weeks: we're pushing harder. 1,400 calories is below your BMR, and that's a calculated risk I'm taking because Tirzepatide 5mg is doing real physiological work to protect your muscle tissue. But this only works if protein stays at 140g every single day. If you drop protein, you drop muscle. That's not negotiable.
The supplements I've listed are not optional extras — they're part of the system. Creatine protects your performance output. Magnesium protects your sleep. Electrolytes protect your training. Omega-3 is actively attacking your visceral fat. D3 is supporting hormone production. You've earned the right to push this hard — don't undermine it by skipping the support structure.
What I need from you: track your protein daily. Train with effort even when the deficit makes it hard. Hit your water. Sleep 7-8 hours. And book the Week 4 InBody scan now — accountability is built into the calendar, not the motivation.
The 160s are yours. Let's go get them. — Coach Larry
