Greg Doucette's clients stay full while they lose weight. Here's how to build that same high-volume deficit for a whole roster.
"Just eat less" is why most diets fail. The idea underneath Doucette's high-volume approach is the opposite - anchor each meal in protein, then fill the plate with low-calorie, high-volume food so a client eats a large amount and still lands in a deficit. This breakdown covers his argument in our own words, adds our honest take for coaching real clients, and shows how to template a satiety-first plan once and reuse it across everyone you coach.

the short version
Doucette's video argues that people keep weight off when the diet is survivable - so you anchor every meal in lean protein, fill the rest with high-volume, low-calorie-density food, and swap favourite foods for lower-calorie versions instead of banning them. The one thing a coach should do about it: stop programming a client's deficit around smaller portions and start programming it around satiety - same calories, more food on the plate, foods they'll actually keep eating.

Who is Greg Doucette, and why coaches watch
Greg Doucette is a Canadian IFBB pro bodybuilder and coach, and one of the most recognisable voices in fitness YouTube. He's best known for "high-volume dieting" and his "anabolic" cookbook franchise - lower-calorie versions of the foods people actually crave. His whole pitch is adherence: build a deficit a normal person can live inside, not a crash diet they endure and abandon. For coaches he's a useful reference precisely because clients quote him - so it pays to understand the mechanism, not just the memes. That's the lens this page is written for: not "should I copy his recipes," but "what does his satiety-first argument mean for how I program nutrition across a client roster."
What Doucette actually argues (our summary)
This is our summary of the ideas in the video, in our own words - not a transcript. Watch the original for his exact examples and recipes.
- 1
Protein is the anchor of every meal. Lead with a lean protein source first - it's the most satiating macro and the non-negotiable that every other choice is built around, not an afterthought.
- 2
Fill the rest with high-volume, low-calorie food. Once protein is set, bulk the plate out with foods that take up space for few calories, so the client physically eats a lot while staying in a deficit. Satiety, not smaller portions.
- 3
Swap favourite foods, don't ban them. His "anabolic" recipe idea is re-engineering the meals a client already wants into lower-calorie versions - so a craving becomes a planned swap instead of a blown day.
- 4
Track honestly. The deficit still has to be real. High-volume food and swaps make the calories livable, but they don't replace honest tracking of what actually goes in.
- 5
The goal is keeping it off, not losing it fast. The whole point of the video's title: a plan you can stay on beats a crash diet you survive. Build the deficit around food a person can eat for the long run.
Coachway's take
We're fully on board with the core idea, and it's the reframe most coaches need: a client doesn't fail a diet because they lack discipline, they fail because they're hungry. Engineering satiety into the plan - protein first, then volume - does the adherence work up front instead of leaving it to willpower. "Eat less" outsources the hard part to the client; "eat differently" is the part a coach can actually program.
Where we'd add nuance for a coaching business: high-volume dieting is a tool, not the whole plan. It makes a deficit livable, but the deficit still has to be set correctly and tracked honestly - and some clients will happily eat a mountain of low-calorie food and still overshoot on the protein-and-fat sources. So we treat the high-volume swaps as the satiety layer on top of a real calorie and protein target, not a replacement for one. Volume without a number is just a bigger plate.
The other coaching-specific point he doesn't have to worry about: he's cooking for himself and an audience at scale. You're feeding twenty different lives, tastes and kitchens. The perfect swap is worthless if the client hates cauliflower rice or never cooks. So the real skill is personalising the swaps - keep the mechanism (protein anchor, add volume, swap don't ban), but fit it to foods each client will genuinely keep eating. That's the difference between a plan they follow for a week and one they keep off.
So our version of his advice is: set a real calorie and protein target, then build the plan around high-volume, high-satiety food and lower-calorie swaps of foods the client actually likes - and verify adherence through logging and check-ins instead of guessing. Then, and this is the part that saves your evenings, build that satiety-first day template once and reuse it across clients instead of writing every meal plan from scratch.
Build the high-volume plan once, then watch real adherence
A satiety-first plan only pays off if you can deliver it and actually see whether the client sticks to it. That's what Coachway's meal planner is for: build high-volume, high-protein day templates - protein anchor plus low-calorie volume, with swaps a client will keep eating - then assign them and tweak per client instead of rewriting every plan from scratch. Clients log their meals in the client app, so instead of guessing why someone "can't stick to the deficit," you can see it in their food log and read the drift early.
Then progress tracking and check-ins tie satiety back to results - if adherence is slipping, you adjust the swaps, not just the calories. If you want the strategy layer first, our guide to flexible dieting covers the "no banned foods" logic, and our breakdown on setting protein targets for clients covers the anchor the whole high-volume plate is built around.
High-volume food swaps (same protein, fewer calories, more food)
A client handout you can copy for anyone dieting. Each swap keeps the meal a client already eats but cuts its calorie density, so they can eat a larger amount inside the same deficit. Personalise it - only keep the swaps a given client will actually enjoy. The rule at the bottom is the whole method in one line.
High-volume swap list
Swap this for that
| Instead of | Swap to | Why it works |
|---|---|---|
| Regular ground beef | 96% lean beef or turkey breast | Same protein, far less fat and calories |
| Oil frying | Air-fry or zero-cal spray | Cuts hidden liquid calories |
| Full-fat cheese | Light / fat-free cheese | Keeps the flavour, drops the density |
| Rice / pasta | Cut half with cauliflower rice, edamame or shirataki | Doubles the volume, halves the calories |
| Sugary drinks | Zero-cal flavoured drinks | Removes easy liquid calories |
| Peanut butter | Reconstituted PB powder | Same taste, a fraction of the fat |
| Chips | Popcorn or rice cakes | More to eat for fewer calories |
The rule: build every meal around a lean protein first, then add volume - veg, salad, broth - so the client finishes full inside their calories. Swaps make the deficit livable; they don't replace a real calorie and protein target.

High-volume dieting for clients - FAQ
What is high-volume dieting?
High-volume dieting is the approach Greg Doucette is best known for: anchor every meal in a lean protein, then fill the rest of the plate with foods that take up a lot of physical space for very few calories - vegetables, salad, broth-based soups, and lower-calorie-density swaps. The point isn't a special metabolic trick; it's satiety. A client eating a big bowl of food feels fed while still sitting in a calorie deficit, which is what makes the deficit survivable week after week. For a coach, it reframes fat loss from 'eat less' to 'eat differently' - same calories, far more food on the plate.
How do you keep a client full while they are in a calorie deficit?
You change the food, not just the portion. Doucette's method is to lead with protein (the most satiating macro), then bulk the meal out with high-volume, low-calorie foods so the client physically eats more, not less. The practical coaching version: for each meal a client struggles with, keep the protein, then add volume - extra veg, a large salad, a zero-calorie sauce, a soup starter - so the plate looks and feels like plenty. Hunger, not willpower, is what breaks most diets, so engineering satiety into the plan is doing the client's adherence work for them up front.
Do clients have to eat "clean" to lose weight?
No - and that's a big part of why Doucette's 'anabolic' recipe idea resonates. Instead of banning a client's favourite foods, you build lower-calorie versions of them: the same meal a client actually wants, re-engineered to fit their calories. A craving that used to blow the day becomes a planned, lower-calorie swap that keeps them on track. As a coach, that's a more honest and more durable position than a list of forbidden foods: fat loss comes from the calorie deficit, and the swaps just make that deficit livable so the client isn't white-knuckling it.
Why do most diets fail, and how do you keep the weight off?
The title of the video is the whole point: losing weight is common, keeping it off is the hard part. Diets fail when they rely on hunger and restriction the client can't sustain, so the moment life gets busy the plan collapses. Doucette's answer is a deficit built on high-volume food, honest tracking and swaps a person can eat for the long run - a plan you could stay on, not just survive. For a coach, 'keep it off' means the program has to still work at month six: high satiety, foods the client likes, and check-ins that catch drift early rather than a crash diet that ends the day it ends.
