If your goal is to use intermittent fasting to boost your progress, try very hard to avoid snacking. For me, I can tell the difference when I snack, even when what I eat is very high fat. While pure fat (butter, for example) might be manageable, anything with significant amounts of protein or carbs (even if relatively small amounts) can provoke an insulin response. Do that throughout the day, and you may stall even with keto-friendly snacks.
Restricting calories won’t help, and in fact may be counterproductive, as it will tell your body that there’s food, but not enough, and may result in a drop in basal metabolic rate. You’ll likely feel tired, and cold, and crappy, and it probably won’t move the needle much, if at all.
Make a plan. Whether that is one meal a day IF, or following specific macros, or doing the occasional extended fast. Any of those should help. Some other ideas:
- Consider trying a week or two with 45-50g of protein instead of 60, and get the replacement caloric intake from fat, and see what happens.
- Try eliminating all dairy for a week or two.
- Try getting carbs down to an even lower level (drop veggies if you need to), like 5g.
- Make sure that you aren’t allowing carbs to slip in here and there uncounted, as with HWC, which in the US says 0g of carb per serving, but it’s actually more like 0.4g, so if you’re using a lot, it can add up.
- Also be aware that some non-caloric sweeteners use dextrose or maltodextrin (or both) as bulking agents. If you only use one packet a day, probably no biggie, but if you’re using a lot, this will also add up.
- If you are confident that you’re fat-adapted, consider trying an extended (multi-day) fast. You can do a full-on water-only fast, or you can supplement with fat (butter, coconut oil, MCT oil (in moderation, especially at first)). Make sure to get plenty of water, and add salt to the water, as you’ll need it. Also a good idea to bump up other electrolytes while fasting.
I can definitely sympathize with the frustration. Most of us have had ups and downs. Stick to the basics, and it will usually work eventually. Good luck!
