Still Hungry on Keto? What to Do in Month One, and What to Check After Week Six
In this video
This one was made to be dropped into a thread whenever someone posted "I'm starving." The answer depends on where you are.
- [0:00] If you're in month one, you shouldn't be restricting calories.
- [0:30] The first 30 days are for learning labels and recipes, not for forcing a painful diet on yourself.
- [1:00] Glycogen is draining and insulin stays high for weeks, so you'll feel flat and hungry. My answer: eat fat. But protein comes first; work out your target with a calculator.
- [1:30] Still hungry in month two, especially past week six? Look for hidden sugars, triggers and psychological factors.
- [2:00] In the weight-loss phase, fat can come way down. Some people try fasting, as long as protein and fibre are covered.
- [2:30] In the race for results posted on social media, some people flirt with anorexia. If you're going to restrict, include your doctor.
- [3:00] In the weight-loss phase you should be at a deficit and fairly comfortable. If you aren't, get help troubleshooting hidden carbs.
- [3:30] Month one is the hardest. Be patient and wait for the hunger to go.
Watching this in 2026
The structure is the best part: hunger means different things at different stages. Week-two hunger is normal. Week-ten hunger is information.
What I'd tighten is the order of advice. I said "eat fat, eat lots of fat" first and got to protein a sentence later (from the video). Protein should lead, not follow. The research below is the reason.
The claim worth unpacking: protein first
I called protein "your first goal" (video 7Aixw4uRksI), and the evidence backs putting it at the top of the list for hunger.
- In Weigle et al., 2005, raising protein from 15% to 30% of energy, with carbs unchanged, cut what 19 adults chose to eat by 441 kcal a day. Weight fell 4.9 kg over 12 weeks.
- A review by Westerterp-Plantenga et al., 2009 found protein increases satiety and helps keep fat-free mass.
- Leidy et al., 2015 associated about 1.2–1.6 g per kg a day, with about 25–30 g per meal, with better appetite control and weight management.
That last number is the practical one. If breakfast is coffee and a few bites of cheese, that's a likely reason you're hungry by ten. More in protein per meal.
Fibre belongs on the list too. I mentioned it next to protein for anyone fasting (from the video). Across trials, more viscous fibres reduced appetite in 59% of comparisons, against 14% for less viscous ones (Wanders et al., 2011).
"Eat fat to fill hunger" is still fine advice for month one. It just works better after protein is handled than instead of it.
The line that holds up: the anorexia warning
In a four-minute beginner video, I stopped to say the chase for social-media results pushes some people toward anorexia, and that any deliberate restriction plan should include your doctor (video 7Aixw4uRksI). That line stays.
Here it is more specifically. If you have a history of an eating disorder, involve your therapist and your doctor before you start tracking or fasting. I said the same about therapists in another video (video xyEZL0HuejI).
There's also a medical-reason case. If you need to lose weight quickly for a health reason, that plan belongs with your doctor, not a forum.
Then vs now
The month-one rule here matches what I said a month earlier: deficit yes, restriction no, eat until you're full (video 8Jk5ShSUpFY).
The second half is where my wording varied. Here, fat "can" come down in the weight-loss phase. A week earlier I had put it as a direct instruction to stop eating too much fat (video NUJNFG6lLWw). By 2018, fat was the macro you move up or down by phase while protein stays put (video UygKGoP_BtA). So if you're past week six, hungry and not losing, look at the fat bombs and the butter in the coffee before anything else.
What "hidden carbs" usually means
I left "hidden sugars" undefined in the video. In practice it's the things you don't log: sauces, dressings, "keto" snacks, the coffee add-ins, the handful of nuts that's actually three handfuls. Week-by-week checks are in hidden carbs and hidden calories.
Key points
- Hunger in month one is expected. Hunger after week six is a sign to troubleshoot.
- Month one: hit protein, keep carbs low, eat enough fat to stop being hungry. Don't restrict calories yet.
- Protein first. Higher protein reduced intake in a controlled trial (Weigle 2005); about 25–30 g a meal (Leidy 2015).
- Viscous fibre helps appetite in most trials (Wanders 2011).
- Past week six: check hidden carbs, triggers, and the amount of added fat.
- Eating-disorder history or a medical need to lose weight fast: therapist and doctor first.
