[...] Agricultural data from 38,700 farms plus details of processing and retailing in 119 countries show wide differences in environmental impacts — from greenhouse gas emissions to water used — even between producers of the same product, says environmental scientist Joseph Poore of the University of Oxford. The amount of climate-warming gases released in the making of a pint of beer, for example, can more than double under high-impact production scenarios. For dairy and beef cattle combined, high-impact providers released about 12 times as many greenhouse gases as low-impact producers, Poore and colleague Thomas Nemecek report in the June 1 Science.
[...] The greatest changes in the effect of a person’s diet on the planet, however, would still come from choosing certain kinds of food over others. On average, producing 100 grams of protein from beef leads to the release of 50 kilograms of greenhouse gas emissions, which the researchers calculated as a carbon-dioxide equivalent. By comparison, 100 grams of protein from cheese releases 11 kg in production, from poultry 5.7 kg and from tofu 2 kg.
[...] Producing food overall accounts for 26 percent of global climate-warming emissions, and takes up about 43 percent of the land that’s not desert or covered in ice, the researchers found. Out of the total carbon footprint from food, 57 percent comes from field agriculture, livestock and farmed fish. Clearing land for agriculture accounts for 24 percent and transporting food accounts for another 6 percent.

When you say "fasting", is that all she cut out? Did she cut out other food that normally goes with meat too? What did she replace that with?
I can tell you that I eat a *lot*. I'd never use the word "fasting" to describe my diet because that (to me anyway) implies just skipping some or all food, as opposed to replacing it with alternatives.

Unfortunately, she did - restricted herself on two meals on those days (skipping breakfast).

Understood. Sorry, I wasn't aware.
I figure vegans probably need to eat a lot more food than normal to keep up their health as a general rule, but I'm no health expert.
I used to skip breakfast for years (but would easily make up for it in other meals). These days though, with all the running I've been doing, I have a strong craving for food at breakfast time.

No apologies needed.
Just keep in mind "an anecdote doesn't a dataset make" next time you are tempted by "You don't need to eat meat products to be healthy." kind of generalizations.
