Fat loss
The Fat Loss Stack
A sustainable deficit, protected muscle, and honesty about the one drug that actually changed the game.
For: Anyone trying to lose fat and keep the muscle — and anyone weighing a GLP-1.
Fat loss is energy balance, full stop, and every 'fat-burner' supplement is a distraction from that. Build a modest deficit you can sustain, keep protein and resistance training high to hold onto muscle, and use fiber and caffeine as honest, marginal helpers. GLP-1 medications are the real exception — genuinely powerful for the right person, and a clinician conversation, not a shortcut.
Fat loss is the goal with the most snake oil per square inch, and the underlying mechanism is almost insultingly simple: energy balance. A modest, sustainable deficit is the entire engine. Everything useful in this stack either helps you hold that deficit or protects your muscle while you’re in it — and everything useless is trying to sell you a shortcut around it.
So the base is a food pattern you can keep, high protein, and resistance training to tell your body to hold onto muscle rather than burn it, with easy cardio or steps adding to the gap. Fiber and caffeine are honest, marginal helpers. The one genuine game-changer is the GLP-1 class — semaglutide and its cousins produce weight loss and cardiovascular-risk reduction that lifestyle alone rarely matches. But it’s a prescription with real side effects, real cost, and open questions about muscle loss and stopping, which is exactly why it belongs in a monitored clinical relationship and works best layered on top of the base here — not as a replacement for it. Berberine, meanwhile, is not an over-the-counter version of it, however the label reads.
The protocol
The backbone
Does the work. Build these first.- Nutrition Foundations B
A modest, sustainable energy deficit built from a pattern you don't hate. This is the whole mechanism.
- Protein Foundations B
Keep it high (~1.6 g/kg or more) to preserve muscle in a deficit.
- Strength Foundations A
Non-negotiable in a cut — it signals the body to keep muscle instead of burning it.
- Aerobic base Foundations A
Adds to the deficit and improves fitness; walking counts.
Worth adding
A real, evidence-backed boost on top of the base.Situational
Low-stakes; useful only in the right case.- Berberine Supplements C
'Nature's Ozempic' is marketing. Modest glucose/lipid effects; it is not a GLP-1.
Understand, don't just add
Powerful or hyped — a clinician conversation, not a casual add.- GLP-1 (semaglutide) Medications A
For obesity or real cardiometabolic risk, under a clinician — powerful, with real side effects and cost. Pair with protein and lifting to protect muscle.
Build it in this order
- 1 Set a modest deficit from a food pattern you can actually keep.
- 2 Push protein up and keep resistance training in — that's what preserves muscle.
- 3 Add walking or easy cardio for extra deficit and fitness.
- 4 If obesity or cardiometabolic risk is in play, discuss a GLP-1 with a clinician — as a tool on top of the base, not instead of it.
What to skip
- 'Fat-burner' and 'metabolism-boosting' supplements — they do essentially nothing.
- Crash deficits that torch muscle and rebound.
- Treating berberine as an over-the-counter Ozempic.
