You might think the key to weight loss is eating less and moving more. If a modest calorie deficit is effective for weight loss, a bigger one must lead to even better results. But the truth is that eating too little can hurt your weight-loss efforts, especially in the long run.
When you severely cut calories, your body doesn’t celebrate the deficit; instead, it fights back. Hunger roars, hormones shift, and your metabolism slows to a crawl as if your body is pulling an emergency brake. The result? A diet that might seem like a quick fix, but in the end, extracts a heavy toll: short-term gain with a long-term cost.
