Just when we thought we’d heard of every diet fad out there (ban carbs! skip sugar!), a new one recently popped up that genuinely took us by surprise.
In his new book, The Plant Paradox, Steven Gundry, M.D., a cardiologist and heart surgeon based in Southern California, claims that the worst food for weight loss is any food containing a plant protein called lectin. But here’s the thing about lectins: They’re found in foods you’ve always thought were good for weight loss. Think: whole grains, beans, nightshade vegetables (eggplant, potatoes, tomatoes, peppers, squash), legumes, nuts, seeds, dairy, and any animal protein that’s not pasture-raised (eggs, meat, poultry).
