However, meat is not an essential part of each meal. Veggies and grains are much healthier than having bacon for breakfast, a turkey sandwich for lunch, and meatloaf for dinner. I don't think our bodies can process that much meat in a day.
A merely unfat person's diet is not appropriate for someone trying to lose weight, that is what people never understand in these things. They think, I'm healthy, eat what I eat and you'll be a healthy weight too. No. If your diet leaves your weight stable, and a fat person eats it, they will stay fat.
To lose significant amounts of weight, caloric intact has to be 3/4 to 1/2 sustaining levels. If you eat that little with lots of carbs, you will be starving 8 hours out of every 24, and nobody keeps it up.
A fat person needs to cut calories drastically, way below what thin people consume, and needs to do so without feeling hungry all the time. The right way to do that is as the article says, to up protein intake (especially - it mentions time to digest fat but that is not nearly as critical, since inadequate protein intake will trigger hunger to get enough) - and also relatively narrowly spaced but quite small meals.
There is no way to eat 1500 calories a day in only 3 meals without hours of hunger. There is no way to eat 1500 calories a day with a calories to grams of protein ratio of 30 or 40 without hunger, because the body will immediately demand 75 grams and tell you to keep eating until it gets them.
But you can readily eat just 250 to 300 calories at a time and feel full enough to stem hunger. And if you include enough meat and the like, you can get calorie to protein gram ratios of 15 or 20 (10 and under from the protein sources themselves, but balanced with other foods). If you get 1500 calories and 75 grams of protein or more and can eat something small every 3-4 hours, you will not feel hungry.
Lean people give the worse advice on this stuff because they assume anyone acting as they act will have a weight like theirs, but it is not remotely true. To beat a real weight problem takes a massive caloric restriction sustained enjoyably for 6, 9, 12 months. The ways of doing that are much narrower than the fools giving the advice based on some non-losing norm can grok. They always bring in their ulterior motives and break the people they are advising out of the only patterns that can actually do it.
The rule my wife and I follow is "eat meat sparingly". Some may recognize that rule. It is part of a set of rules that we follow that we've had so much success with.
