In postmenopausal women on a vegan diet, eating more or less processed plant foods like vegan burgers or packaged snacks had no effect on weight or hot flashes, suggesting that how processed plant foods are doesn't matter for these health outcomes.

In women on a vegan diet, eating more or less processed plant foods like vegan burgers didn’t change their weight or hot flashes — the study found no link. What did help was cutting out animal foods, but that’s not what the claim is about.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether ultra-processed plant-based foods (e.g., vegan meats, snacks) have no consistent effect on body weight or hot flash frequency in postmenopausal women across diverse dietary contexts.
A systematic review and meta-analysis of RCTs comparing diets high vs. low in ultra-processed plant foods (≥30% of calories) in postmenopausal women, measuring weight and hot flash frequency over 8–16 weeks, requiring at least 8 trials with 500+ participants.
Whether increasing ultra-processed plant foods while maintaining total calories and plant protein intake affects weight or hot flashes in postmenopausal women.
A double-blind RCT of 120 postmenopausal women with ≥2 severe hot flashes daily, randomized to either a vegan diet with 40% of calories from ultra-processed plant foods (e.g., mock meats, snacks) or a vegan diet with 40% from whole plant foods, matched for protein, fiber, and fat, measuring weight and hot flash frequency over 12 weeks.
Whether long-term intake of ultra-processed plant foods predicts changes in body weight or hot flash frequency in postmenopausal women over time.
A prospective cohort study following 3,000 postmenopausal women for 5 years, tracking annual intake of ultra-processed plant foods via food diaries and biomarkers, and measuring weight and hot flash frequency via validated tools, adjusting for soy intake, physical activity, and hormone therapy.
Whether women who did not lose weight or reduce hot flashes on a vegan diet consumed more ultra-processed plant foods than those who did.
A case-control study comparing 100 non-responders (≤10% weight loss or ≤30% hot flash reduction) to 100 responders after 12 weeks of vegan diet, assessing intake of ultra-processed plant foods via detailed dietary recall, matched for age, BMI, and soy intake.
Whether, at a single point in time, postmenopausal women consuming high amounts of ultra-processed plant foods report similar weight and hot flash frequency as those consuming whole plant foods.
A national cross-sectional survey of 5,000 postmenopausal women measuring current intake of ultra-processed plant foods, body weight, and hot flash frequency using standardized tools, stratified by age, ethnicity, and socioeconomic status.
