The other catch: The amount of weight lost doesn't seem to be any more than what you’d expect from another calorie-restricted diet, and depending on how many calories you’re eating each day, you could even end up gaining weight. After all, the diet doesn’t restrict high-calorie foods. When the diet is done properly, IF can be as effective as normal caloric restriction, Dr. Lowden says. Some people, especially busy people who don’t have time to devote to meal planning, might even find a time-restricted diet easier to follow than something like the keto diet or the paleo diet, she says.
