Based on my experience with a keto pescatarian diet from 2018-2021: when keto starts to fail it's because you're no longer in ketosis. I found it hard to restrict carbs enough to stay in ketosis and I found hunger prevents you from getting back into ketosis. The trick I learned to get back into ketosis, was to make the next 2 meals zero carb (eg. fish). I used a cheap alcohol breath tester to check - the sensor in the cheap ones also responds to acetone (mistaking it for alcohol) so you get reading, any non-zero value means your ketogenic (if you've not consumed alcohol).
I disagree. Beef is concentrated nutrients (vitamins and minerals) from an animal on a plant based diet.
Take for example calcium - there is no way we could acquire the recommended RDI from any source other than milk. Milk is perfectly designed for young animal to grow into an adult. It even stimulates hunger to accelerate this process. Why do many humans (unlike any other animal) never ween themselves off milk? When our bones have finished growing, why do we need calcium? - the RDI is wrong for adults. Even if we break a bone the body can recycle calcium and repair the bone break.
And all the nutrients in meat are in the active form our bodies require. Consider the fat soluble vitamins:
- Vitamin A as retinol, retinal, retinoic acid - not beta-carotene from plants that needs to be converted.
- Vitamin D3 - not D2.
- Vitamin E as α-tocopherol - not γ-tocopherol and tocotrienols that predominate vegetable seed oils.
- Vitamin K2 - not K1.
- Omega 3 DHA and EPA - not ALA.
How do you obtain these nutrients in sufficient amounts on a low fat plant based diet?
The US Dietary Guidelines are 80-85% based on Epidemiology (not science) and the rest is based on cherry picked scientific trials that align with their vegetarian ideology. The
20 dietary guidelines advisory committee members are predominantly vegetarians. Google each name and see for yourself.
Based on ideology and dogma they are trying to steer us away from our natural ancestral animal based diet and as a consequence destroying nature and our health.
Only animals can restore our top soil and prevent climate change by returning carbon to the soil which improves drainage and water holding capacity, thereby
reducing runoff and down stream flooding.
Sorry for going off topic at the end.
