The 3 phases

The strength workouts

How to run them: after a 5-minute warm-up (easy cardio, cat-camel, hip hinges, arm circles and a light set of the first move), do the exercises in pairs. Do A1, rest 30–45 s, do A2, rest 30–45 s, and repeat for all sets, then move on to B1 and B2, then C1 and C2. RIR means reps in reserve: RIR 2 means you stop with two good reps left. Add weight when you reach the top of the rep range on every set.

Optional finisher in weeks 9–12: if you feel recovered, finish with 6–8 minutes of intervals on a bike or rower: 30 s hard, 30 s easy. Skip it if you slept badly. Easier options: box squats to a bench for sore knees, chest-supported rows and a hinge to knee height for your back, and incline push-ups or a neutral grip for your shoulders.

Zone 2 sessions

  • What: brisk or hilly walking, cycling, rowing or an easy jog at a pace where you can still talk in full sentences.
  • Heart rate: get your personal range with the zone 2 heart rate calculator.
  • Why: it builds heart health and endurance without eating into your recovery from lifting, and together with your steps it helps you reach the WHO target of 150–300 active minutes a week.

Weekly habit focus

One habit a week. Keep the earlier ones going as you add each new one.

Week Habit This week
1 Know your starting point Weigh yourself on at least 3 mornings, measure your waist, and note your average daily steps. Set your targets with the calorie and protein calculators.
2 Protein at every meal Build each meal around a protein: eggs, Greek yogurt, paneer, tofu, dal, chicken or fish. Aim for your daily target from the protein calculator.
3 Walk after meals Add a 10-minute walk after one or two meals a day. It is the easiest way to raise your steps.
4 Sleep 7 hours or more Fix your wake-up time, set a bedtime alarm and keep screens out of bed. Short sleep makes hunger and cravings harder to manage.
5 Alcohol Set a weekly drink limit below 14 units, with several alcohol-free days. Fewer is better: alcohol adds calories and hurts sleep.
6 Vegetables and fibre Fill half your plate with vegetables at lunch and dinner, and add beans, lentils or fruit daily.
7 Drinks without sugar Swap sugary drinks, juices and sweet coffees for water, sparkling water, or tea and coffee without sugar.
8 Plan your weekends Plan meals out in advance, eat protein first, and keep your steps up on Saturday and Sunday.
9 Manage stress Take 10 minutes a day to decompress: a walk without your phone, breathing or meditation.
10 Hunger toolkit Start meals with protein and vegetables, keep easy high-protein snacks at home, and do not shop hungry.
11 Active family time Plan one active outing with the kids: a park, bike ride, swim or backyard cricket.
12 Your maintenance plan Decide your next step: keep losing, or move to maintenance calories. Keep 3 workouts and your step target as non-negotiables.

Weekly check-in rules

  • Weigh in on at least 3 mornings a week (daily is best), after the toilet and before eating or drinking, and use the weekly average. Single days jump around with salt, carbs and water.
  • Measure your waist once a week, on the same morning: find the bottom of your ribs and the top of your hips, and measure halfway between them, breathing out naturally.
  • Target: lose about 0.5–1% of your body weight a week. Slower than that is still progress; much faster tends to cost muscle and energy.
  • Judge trends, not days: only change something after two weeks of data, and change one thing at a time. The first week or two often show a bigger drop that is partly water.
  • Waist down, weight flat? Common when you start lifting. Keep going.

Quick check-in

Enter last week’s and this week’s average weight (any unit, but the same for both).

Please enter both weekly averages (between 30 and 400).

How to adjust your calories

  1. Set your start: use the calorie calculator for a daily target that loses 0.5–1% of your weight a week, and the protein calculator for your protein (research supports about 1.6 g per kg of body weight a day or a bit more while dieting).
  2. On track (0.5–1% a week): change nothing.
  3. Too slow for two weeks and your waist is not shrinking: first check weekends, drinks and portion sizes, then add 1,000–2,000 daily steps (about 10–20 minutes of brisk walking), then trim your intake with one small change such as one snack or one drink less.
  4. Too fast (over 1% a week for two weeks after week 2), or you feel drained and your lifts are dropping: eat a little more, mainly from carbs around your workouts.
  5. Every 4 weeks: re-run the calorie calculator with your new weight. A lighter body burns a little less, so your target should come down slowly as you lose.
  6. Never crash diet. Very-low-calorie diets should only be done with medical supervision.

How this 12-week fat loss program works

Fat loss after 35 comes from a modest calorie deficit, while lifting weights and eating enough protein make sure the weight you lose is mostly fat, not muscle. The three full-body workouts follow ACSM guidance to train every major muscle group at least twice a week, the supersets keep each workout to about 40 minutes, and effort rises across three phases.

Steps are the backbone of the plan because they burn energy without hurting recovery. A 2022 analysis of 15 studies found that, for adults under 60, the lower risk of early death levelled off at about 8,000–10,000 steps a day, so the plan builds you up to that range. A brisk walk of about 100 steps a minute counts as moderate activity, so 1,000 extra steps is roughly 10 minutes of walking. Zone 2 sessions add heart health and endurance on top.

The weekly habits target what actually stalls fat loss in busy dads: low protein, short sleep (in one controlled trial, dieters who spent 5.5 hours a night in bed lost less fat and more muscle than when they spent 8.5 hours in bed), weekend drinking and sugary drinks. The check-in rules use weekly averages and your waist so you react to real trends, not daily water swings. A rate of 0.5–1% of body weight a week is the pace experts recommend for keeping muscle.
