I heard that more diseases are caused by too much protein than by too little though e.g. https://www.medicinenet.com/script/main/art.asp?articlekey=50900
WTF @ that article, terrible. I don't know where to start.
Nobody's saying not to eat a balanced diet. I have never once seen a case where ketosis was caused by high protein intake; that tends to stem from high fat/low carb diets (because ketone bodies are a result of lipid metabolism, which the body resorts to as an energy source when glucose is depleted). You don't want to cut out carbs or fat at all; your body needs both. Keep eating fruits, veggies, grains, etc, but adjust your protein intake with your exercise level. Your balance is going to depend on how often and how intensely you exercise, and your metabolism.
I had a look at protein bars, they're very expensive for just one bar (>1.50).
Protein powder is around £30 per tub.
Bars do tend to be a little expensive, but you can get whey powder VERY cheap online, and sometimes elsewhere. Check out Scivation's website.
The thing about ordinary food being better - presumably to body build rather than tone or slowly build you'd need to eat a lot more of it.
What ordinary food is good for eating after a workout in the evening, training that would build muscle? Bear in mind that if it's late then you don't want to make or eat a meal. I usually eat nuts, fruit. What else is there?
I don't "cook" (although my wife does, but she's often either not home or not awake at all the times I want to eat
), but I make stuff like eggs or grilled chicken breasts and occasionally I'll do it fairly late at night. I'll eat snacks like cheese slices or beef jerky or nuts or yogurt, I'll drink milk. Basically whatever I have around.
I don't normally drink protein shakes other than post-workout, but a lot of people like to have one before bed or at other times that they're hungry between meals.
