The guides

Fifteen of them, written to go with the calculators — what the numbers mean, where they break down, and what to change when progress stops.

Fasting

• How to Pick a Fasting Window That Fits Your Training Your fasting window and your training slot have to share the same day. Here is how to arrange them so neither one wrecks the other.
• Should You Train Fasted? What Actually Changes Fasted training changes which fuel you burn during the session. Whether it changes your results over weeks is a different question entirely.
• How to Break a Fast Without Undoing the Day The meal that ends your fast sets up everything that follows it. Here is how to build it so the rest of the window stays under control.
• 16:8 vs 18:6 vs 20:4 vs OMAD: Which One People Actually Keep A comparison of the common fasting protocols by the only measure that decides results — whether people are still doing it three months later.

Energy

• TDEE Explained: Why the Number Is a Starting Point What total daily energy expenditure is made of, why calculators disagree with each other, and how to find your real number in two weeks.
• Why Your Metabolism "Slows Down" on a Diet Metabolic adaptation is real, mostly explainable, and smaller than the internet claims. Here is what actually changes and which part you can control.

Protein

• How Much Protein You Actually Need The protein range that covers almost everyone, why a calorie deficit raises it, and the one-week test that shows whether you are actually hitting it.
• Protein Timing: What Matters and What Was Oversold The anabolic window, per-meal doses and protein before bed, ranked by how much difference each one actually makes next to your daily total.
• Hitting Your Protein Target on a Short Eating Window A four or six hour window and a 180 gram target do not automatically fit together. Here is how to make them fit, and when to widen the window instead.

Planning

• How Fast Should You Lose Fat? Picking a rate of loss is the decision that determines how much muscle you keep and whether you finish the phase at all.
• Diet Breaks: Why Planned Pauses Beat Grinding A maintenance week is not lost progress. It is what makes the deficit weeks repeatable — and taking them on schedule beats taking them when you break.
• What a Realistic 16-Week Fat Loss Plan Looks Like Week by week: what changes, what stays the same, where the maintenance weeks go, and what to do when the scale stops cooperating.

Strength

• How to Estimate Your 1RM Without Testing a Max Testing a true one-rep max costs recovery and carries risk. A set you have already done gives you an estimate that is good enough to program from.
• Picking Your Working Weight for Any Rep Scheme How percentages of your max map to rep ranges, why reps in reserve beats training to failure, and how to warm up to a top set without wasting it.
• Strength Training While in a Calorie Deficit What to expect from your lifts during a fat loss phase, what to change in the programme, and which numbers you should stop chasing entirely.
