You Should Know

(NOTE: I am not a doctor, nutritionist, etc - just someone who has learned a lot of lessons the hard way and likes to share). Without challenging the focus of these stats, I'd like to add two interrelated side-notes (from decades of being professionally physically active, and then decades of being professionally deskbound and too burnt out to move in my spare time, and then getting it mostly back under control later): (1) If you have reached the point where you have long-term struggled with losing weight then - unless you are a very rare exception - changing diet alone will likely not be enough because (2) the steepest but most important curve is "reprogramming your metabolism". One of the most common psychological obstacles I see people hit after years of sedentary living is naively changing only what they eat and getting disappointed when their body doesn't magically "change gears" by itself. The second most common obstacle I see (when people do also start moving their body too) is "counting kilos/pounds" and giving up in frustration when the numbers don't go down straight away, or even go up. When you do "any old exercise" you burn energy while you exercise (which is of course better than not doing any, and helps with aerobic/cardio/psychological fitness too) but beyond that one of the best secrets to serious body transformation is to build muscle (including the women, and not necessarily to a "bodybuilding" degree - a lot of muscle building happens before the "looking jacked" phase). When you do that the increased muscle burns more energy all day and night, not just during the exercise - it reprograms your metabolism. Even better, the longer you do it it doesn't just "change gears" in those moments/days, it teaches your body to become better at "changing gears" in the future. Eventually (unless you have a medical condition, etc) the excess fat burns itself off in service of your body's new functional requirements. Another thing that surprises many is how little resistance training is actually needed for a good baseline to start with (for many people three "adequate but not crazy" workouts per week is enough to see steady progress). BUT a big confusion happens for people weighing themselves all the time - muscle is more dense than fat so there is a good chance if doing it the right (emotionally & financially sustainable) way your overall weight might appear to plateau for ages (or even increase) at first while the increase in dense muscle offsets the loss of sparse fat. I suggest for "tracking weight/fat loss" in most typical cases do so indirectly, not by naively counting loss of overall kilos (of fat, muscle, bones, organs, tendons, ligaments, and so on combined). Regarding diet (especially when exercising) some good rules of thumb are to ensure a broad spread of micro nutrients by shopping for various fruits, veges, nuts, seeds, etc (including semi-regularly surprising yourself with things you usually wouldn't buy to cover the edge-case micros), ensure a good balance of macro nutrients (often the "40 30 30" guide is near enough - 40% carbs, 30% protein, 30% fats - but when strong muscle-building you will need higher amount of protein, covering broad amino acid spectrum), reduce processed foods which are "energy dense" (a euphemism for "nutrient sparse"), keep hydrated, get sun (or other source of vitamin D) every day, reduce sources of stress (stress-addiction to adrenaline and cortisol is real and devastating to your body, and highly addictive if you continue for too long). The most important part is - whatever positive changes you achieve - you need to win the mind-game by making them part of your unquestioning routine, not a novelty that you try to keep kicking down the road. The best equivalent I can think of for this is brushing your teeth - most people find it boring but "just do it" without pondering "will I manage to brush my teeth today". Internalise the other changes the way you brush your teeth.

if that method would work, then it would have a higher success rate than 5 %.

Start every day by drinking 1-2 liters of room-temp water, then waiting an hour to eat.

Eating fruits and vegetables might definitely help and it is in any case very healthy! However, people should not always expect to lose more than 10% of their weight in the long term (over years). This 10% can already provide great benefits for your health, so definitely try to lose that weight if you are overweight.

Often it is said that it is just calories in vs calories out. This is only true up until a certain point. For many people, after losing about 10% of their weight, their body starts to work against more weight loss. Their metabolism starts to slow down and their appetite will increase, making it more difficult to lose weight. It might make it almost impossible to keep on a diet and it might even cause people to gain more weight back than they lost.

The theory behind this is that your body has a set point or settling point for what it thinks your weight should be. When you are overweight, the set point changes to a higher weight. When you lose weight, your body wants to get back to this higher set point. The set point can be changed to a lower weight, but that might take years and years. There also is some limited evidence that building more muscles might help somewhat.

I think it is important to add this to the discussion, as often there is the idea that weight loss is just based on self-control and limiting calorie-intake. While this might play a role, the idea that these are the only factors that determine your weight causes a lot of suffering for people. It might also cause more weight gain in the long term.

So, try to lose about 10% of your weight and if you feel like you are struggling after that, go to a specialised doctor who can help you with losing more weight (doctors without this specialisation are often clueless about weight loss in my experience). In addition, a psychologist might be able to help if your are overeating due to an eating disorder.

Humans don't need grains.

Pretty simple.
