Feel free to let this go.\u2019\u201d<\/p>\n<p>But experts see it differently.<\/p>\n<p>Registered dietitian <a href=\"https:\/\/www.gregorylafortune.com\/\" target=\"_blank\" rel=\"noopener nofollow\">Gregory Lafortune<\/a>, MS, RDN, LD, tells The Post that the whoosh effect is a \u201creal experience, but it is often misunderstood.\u201d\u00a0<\/p>\n<p>\u201cPeople see it as a sudden fat loss from being on the keto diet,\u201d he explains. \u201cInstead, the whoosh effect is attributed to shifts in water weight due to the keto diet. It\u2019s not a sudden loss of fat. It\u2019s a sudden loss of water weight. Fat loss is gradual.\u201d<\/p>\n<p>The purge in water weight might be more pronounced on the keto diet because of how the body stores carbs.\u00a0<\/p>\n<p>A keto diet restricts a person\u2019s intake of carbs like pastas and breads. bit24 \u2013 stock.adobe.com<\/p>\n<p>It\u2019s right there in the name: Carbo-hydra-tes. They\u2019re stored in the body as glycogen, a constellation of glucose molecules. For every gram of glycogen stored, there\u2019s at least <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/25911631\/\" target=\"_blank\" rel=\"noopener nofollow\">three grams of water cached away with it<\/a>.\u00a0<\/p>\n<p>\u201cThis is why someone on a low-carbohydrate keto diet loses water weight,\u201d Lafortune says. \u201cThis differs from other diets because they may not restrict carbs as strictly as keto does.\u201d<\/p>\n<p>Rapid weight loss can indeed occur from a very low carb diet, often within the first few days. But it\u2019s water weight, not fat, as some champions of the whoosh effect claim.<\/p>\n<p>Chasing the whoosh effect isn\u2019t just a lost cause, it can also lead to serious issues like dehydration.<\/p>\n<p>Some keto dieters <a href=\"https:\/\/www.healthline.com\/health-news\/how-the-keto-diet-can-wreak-havoc-on-your-gi-system\" target=\"_blank\" rel=\"noopener nofollow\">talk about diarrhea<\/a> \u2014\u00a0which can dehydrate the body and strip it of important nutrients \u2014 as a sign that they\u2019ve achieved the whoosh effect.\u00a0\u00a0<\/p>\n<p>Some say they\u2019ve triggered the whoosh by other harmful means like yo-yoing between fasting and binging or drinking alcohol for diuretic effects.\u00a0<\/p>\n<p><a href=\"https:\/\/www.healthline.com\/health\/diet-and-weight-loss\/whoosh-effect#is-it-real\" target=\"_blank\" rel=\"noopener nofollow\">According to Healthline<\/a>, \u201ceach of these approaches is aimed at dehydrating your body. While it may make you feel temporarily thinner, it\u2019s not a lasting effect.\u201d<\/p>\n<p>In general, Lafortune recommends setting goals that prioritize long-term health, not just immediate changes in the mirror.<\/p>\n<p>If GLP-1 fever has taught us anything, it\u2019s that rapid weight loss can do real harm to the body.\u00a0<\/p>\n<p>Whether it\u2019s from a diet like keto, a medication like a GLP-1 or another source, Lafortune counts muscle loss, higher risk of regaining weight, slower metabolism, overall loss of strength and energy and sometimes <a href=\"https:\/\/nypost.com\/2026\/02\/09\/health\/people-are-getting-an-old-timey-sailors-disease-on-glp-1s\/\" rel=\"nofollow noopener\" target=\"_blank\">severe nutrient deficiency<\/a> as potential side effects of rapid weight loss.<\/p>\n<p>Suffice it to say, the whoosh effect isn\u2019t the overnight miracle some people make it out to be.
