First up, how much are you trying to lose? Do you know your bodyfat percentage?
So… while there are varying tolerance levels for carbs it is recommended at the beginning that you keep carbs under 20g a day.
Protein can be between .5g-1.5g per kg of lean body mass (recommended towards lower end as too much protein will result in glucose production)
Fat is to satiety. There is no “daily limit” on fat. You eat fat to keep full, and to provide you energy.
On keto, you do not need to calorie restrict, so don’t do it. There is plenty of evidence to show that calorie restriction, especially in insulin resistant people, results in lowered metabolic rate which not only stalls you out as far as weight loss goes but can also make you miserable. If you’re hungry, eat.
Snacking can also become an issue for people, so only try to eat at meals. If you’re hungry between meals, make higher fat meals, and add fat until satiated.
Just to note keto is not a “lose weight quick” way of eating - many people experience a stall between losing initial weight (generally water weight) and continued weight loss down the road, between a month to two months between these points. So if you lose some and stalled out, it is completely normal. Insulin has have time to come down if insulin resistant, inflammation needs to be healed, and hormones are regulated.
So to recap:
- Stop calorie restricting, eat if you’re hungry don’t if you’re not
- Don’t restrict fat, there is no set “fat limit” how much you need will vary day by day. Let your hunger tell you how much to eat
- Carbs under 20g a day
- Protein between .5g-1.5g / kg of LBM
- Try not to snack
My issue with the percentage aspect is every body is different. You probably have more LBM than I do for example, and may need a bit more protein. Percentage doesn’t factor that in. My tolerance level for carbs could be below yours or higher than those of someone who needs to keep below 5g of carb per day. Percentage doesn’t factor that in. I may also be hungrier than you on any given day or you me and need more fat to stay full. Percentage DEFINITELY doesn’t tell you that.
Luckily MFP also tells you the grams of what you’ve been eating in a pie chart, so you can still use it for the recommendations I’ve suggested if you want.
EDIT: Also it goes the reverse as well, if you aren’t hungry you shouldn’t force feed yourself. People can experience a drop in appetite at the start which eventually levels out. If that is why your calories are so low, that is fine for right now.
EDIT 2: Also because of the prevalence of stalls in the beginning stage I recommend people focus on NSVs. Shinier hair? Smoother/softer skin? Clothes fitting better? Aches and pains disappearing? Better/more stable mood? All things to note until you’ve become fat adapted… or any time really!
