Other fasting protocols like Alternate-Day Intermittent Fasting or Water-Only Fasting or Buchinger-style fasting amount to calorie restriction. In some of these fasts, we don't eat anything at all for an entire day. In contrast, in Daniel Fasting, we eat regular meals but restrict the ingredients to fruits, vegetables, whole grains, legumes, nuts & seeds — exactly what Whole Food Plant-Based guidelines asks us to do!

Relationship with Whole Food Plant-Based: On the whole, Daniel Fast (DF) is almost identical to Whole Food Plant Based (WFPB). A big difference that I could identify was with respect to oils: allowed in DF but disallowed in WFPB; some DF websites encourage minimal usage of oils. Also, DF excludes tea, coffee, flours, leavened bread and sweeteners of any kind. All of these are considered part of WFPB; at the same time, those who follow WFPB strictly do remove coffee, flours and sweeteners (except dates & blackstrap molasses, the two healthy sweeteners recommended by Dr Greger). But teas are considered healthy in WFPB. Many Daniel Fast guidelines do allow herbal teas.
