Science Based Diets.

unrefined vegan plate.


calories per volume.

Science consensus is the most reliable thing we have right now.
This brief diet guide is for adults, not including life stages of pre pregnancy, pregnancy and lactation, not including athletes. if ill or on medication, do not make a diet change (or start an exercise program) without the care of a doctor and a nutritionist. Excess weight usually accumulates slowly over many years and decades, so consult a doctor and a nutritionist about the safe rate of weight loss. Too rapid weight lost can result in losing the gallbladder. For many adults, the normal weight was the college weight and or the weight at around age 21. This brief diet guide is the work of 1 person.
The 2 main components of the recent unhealthy industrial diet made possible by fossil fuels and industrial factories are: 1> large amounts of refined chemicals (mostly 0 micronutrients, mostly 0 fiber, mostly high calories) like oil. 2> large amounts of animal products (few micronutrients, 0 fiber, mostly high calories). Science consensus says unrefined plant foods are the healthiest foods so avoid diets that say eat more animal products. Should reduce or eliminate animal products and take vitamin b12 supplement. Vegans who do not take vitamin b12 supplement will surely die. Reducetarians, flexitarians and vegetarians should also take vitamin b12 supplement. Science consensus says fake foods made up of refined chemicals like sugar, oil, salt, protein powder, refined fiber, etc are not healthy. Keep refined chemicals to as few as possible such as vitamin b12 supplement, vinegar, etc. Science consensus says excess calories (including excess protein) will shorten life from worms and insects to apes and people. Examples of science based diets are harvard healthy eating plate, dash diet, cdc national diabetes prevention program diet, volumetrics diet, inventor nathan pritikin diet, dr dean ornish diet, low calorie density unrefined vegan diet with vitamin b12 supplement.
This site is dedicated to my teacher dr bill harris (vegan society of hawaii) who had 1 rule: if it has 0 fiber, do not eat it (some exceptions are vitamin b12 supplement, vinegar). boil dry unrefined plant foods with plenty of water or drink plenty of water bec water is needed for the fiber to work. do not eat in restaurants to avoid food poisoning (my mother died from restaurant food poisoning).

1> refined chemicals are fake foods usually extracted from real foods often using machines (often a source of heavy metals) and often using lots of other refined chemicals (often are contaminants).

2> Animals receive plenty of injections of refined chemicals and antibiotics. Animals are high on the food chain and accumulate over their lifetimes lots of pollutants including thousands and thousands of refined chemicals, micro plastics, heavy metals and radioactive atoms. Animal products are produced in crammed industrial factories and are a source of food poisoning and pandemics. Animal products receive plenty of injections of refined chemicals.
