It's more like they DO NOT want to believe how small portion sizes are required to consistently lose weight. Even if there was a device that could scan all food before eating it, they would still exempt some meals with the "do not count" argument. Rule of thumb, that if a meal is easy and fast to prepare, then it is probably not suited for a diet. To lose weight you have to do a lot more exercise than you think consi…
Went from 230 to ~155 without exercise by calorie restriction alone (600-1200cal/day). It IS possible, though likely unhealthy to accomplish without exercise (I never, ask they say, consulted a doctor prior to the self-imposed restriction). Exercise was uncomfortable until I had lost weight, now I can do 15+ mile hikes with a 60l backpack. I don't want to discourage anyone from doing exercise at any time in their goa…
A simple walk on an incline (5km/hr @ 5% incline) can help you burn 400+kcals/hour. You can probably eat at 1500 kcals and start your day with a walk like that on the treadmill while watching some TV show :).

Indeed it is! :)
If you're obese or severely overweight, it's best to just do a PSMF to lose weight as quickly as possible. Btw, at 230lbs you can easily do strength training which will help you with body recomp (stimulating muscle growth while burning fat).
A good rule of thumb for a PSMF is 9.7x[protein intake]. For example: given 1.6g/kg*104kg = 166g of protein per day we get: 166g * 9.7 kcal/g = 1610 kcal. So your daily calories are at 1610 kcal max, and you need to eat at least 166g of protein (the rest of the calories can be filled with carbs/fat). I suggest min 50g of fat per day for men.
