Chapter 9: Plateaus and Stalls: Why the Scale Stops and What to Do
Most keto "plateaus" are water swings or a normal early pause; a true stall lasts several weeks, and the usual fix is to eat less fat while keeping protein and fiber the same.

The short answer
A stall is a problem only if it is real. Before you change anything, check three things:
- Time. Has the scale been flat for several weeks, not several days?
- Other measures. Are your tape measurements, photos and clothes also flat?
- Intake. Have you tracked a full week of food honestly, including drinks, cooking fat and snacks?
If all three say "stalled," lower your fat intake a little. Keep protein and vegetables where they are. Give the change a few weeks before you judge it.
Stall or fluctuation?
Body weight moves from day to day for reasons that have nothing to do with fat. Water, salt and the food still in your gut can add or remove several pounds overnight.
Two things link water to keto in particular:
- Glycogen. Stored carbohydrate holds water. When you cut carbs, that water leaves. When you eat carbs again, it comes back.
- Sodium and insulin. In a classic study, raising insulin while holding blood sugar steady cut how much sodium the kidneys released (DeFronzo et al., 1975). Less sodium out means more water held in. A carb-heavy meal can show up on the scale the next morning as water.
KetoDick on this: in one video he posts a five-pound overnight gain on purpose, because, he says, nobody posts on the day they gain. His math: five pounds of fat would take far more extra calories than he ate, so the jump is water and digestion. He changes nothing and judges his diet by the week, not the day (video f9P8BPWHc4U). He also ties salt balance and water retention to scale readings (video -dHjt_Bpruk).
The full method for telling the two apart is in Is It a Stall or Just a Fluctuation?.
The expected stall in weeks two to four
Many people lose quickly in week one, then see little change for a few weeks. Most of the week-one drop is water from glycogen (see water weight). The pause after it is common and does not mean keto has stopped working.
KetoDick's stated timeline: water in week one, then little movement for two to four weeks, then fat loss of about 0.5 to 2 pounds a week from month two (video UygKGoP_BtA). He tells beginners not to look at the scale until they are 30 days in, and calls early weight not a "key performance indicator" (from the video) (video xyEZL0HuejI).
His timeline is his own experience and reading. The evidence pages behind this guide do not include a study that sets week-by-week loss rates for keto. See Starting keto: the timeline.
Why the deficit shrinks as you do
Fat loss needs an energy deficit: you use more energy than you eat (see energy balance). A smaller body uses less energy than a larger one. So a meal plan that made a deficit at your starting weight may only break even after you lose.
This is one reason stalls show up after months of steady loss. Nothing broke. The gap between what you eat and what you burn got smaller.
It also explains why keto alone does not beat physics. In a metabolic ward study, cutting carbohydrate led to less body-fat loss per day than cutting the same calories from fat: 53 ± 6 g/day versus 89 ± 6 g/day (Hall et al., 2015). Calories still count.
KetoDick on this: he agrees a calorie deficit matters, but says calorie restriction, forcing yourself to eat less while hungry, is not advisable (from the video). He expects hunger to fall over time so the deficit comes without forcing (video 8Jk5ShSUpFY).
Hidden calories
When hunger is low but the scale is flat, the cause is often calories you do not notice. Common sources on keto:
| Source | Why it adds up |
|---|---|
| Coffee with butter, oil or cream | Large amounts of fat in a drink that does not fill you up |
| Fat bombs | Dense fat with little protein or fiber |
| Nuts and nut butters | Easy to eat by the handful |
| Cheese | Small portions carry a lot of energy |
| Alcohol | Calories with no fullness |
| Sauces, dressings, mayonnaise | Rarely measured |
KetoDick calls fat bombs mostly empty calories (video xyEZL0HuejI), worries that a daily bulletproof coffee is a lot of fat with little other nutrition, and prefers fat from whole foods such as salmon, avocado or chuck roast (video DLRlphyc1t8). He also warns about hidden carbs in nuts and pasta sauces (video LbPnm9T0oxc).
The way to find them is a week of honest tracking. See Hidden Calories That Stall Keto and tracking.
Cut fat, not protein
On keto, carbs are already low. Protein is set by your body size. That leaves fat as the lever you can move.
Protein is the wrong thing to cut:
- In a pooled analysis of 24 trials with 1,063 people, higher-protein diets during calorie restriction gave modestly more weight and fat loss and less loss of lean mass (Wycherley et al., 2012).
- When protein went from 15% to 30% of calories, people ate 441 fewer calories a day without being told to, and lost 4.9 kg over 12 weeks (Weigle et al., 2005).
- One review suggests 1.8 to 2.0 g of protein per kg of body weight per day during energy restriction, depending on the size of the deficit (Phillips & van Loon, 2011).
KetoDick on this: past week five, if you are not hungry but have stalled, he suggests cutting about 20 to 30 g of fat a day, roughly 180 to 270 calories. He says telling month-one beginners to cut fat is "kind of cruel" (from the video), because they are still adapting (video NUJNFG6lLWw). He also says that "breaking a stall" by cutting protein often costs muscle (video UygKGoP_BtA).

Measure more than weight
The scale mixes fat, water, muscle and food into one number. Other measures separate them better:
- Photos from the same spot, same light, same clothes, every few weeks.
- Tape or string around the waist, hips and other set points.
- Clothes fit, using one item you wear often.
- How you feel: energy, sleep, hunger.
If your waist shrinks while the scale holds, you are still making progress. KetoDick recommends photos from day one and tape or string over the scale, and suggests weighing weekly or monthly (video UygKGoP_BtA). He also says social media comparisons can do more harm than the scale (video dNUvzMl-OEU).

When to involve your doctor
Talk to your doctor before you deliberately cut food further if:
- You take medication for diabetes or blood pressure. Eating less and losing water can change how those drugs act, and doses may need review (see medications).
- You have kidney disease or are pregnant.
- You have a history of an eating disorder, or a stall is making you want to eat far less.
KetoDick says anyone on medication should review the plan with their doctor, especially dosing (video UygKGoP_BtA). He warns that chasing posted results can tip into anorexia and asks people to include their doctor in any restriction plan (video 7Aixw4uRksI). See eating disorders.
