First off, congratulations! You’ve made some major positive changes and we hope you’re also proud of yourself.
Since intermittent fasting is not only about losing weight, but also offers many health benefits, you can continue fasting long-term. Just reduce your fasting interval or increase your food intake so that you don't continue to lose weight.
As a head’s up, you may regain minimal weight at first, but there is no reason to panic. This is your body regulating. To avoid re-gaining too much weight, drink enough water, get enough exercise, rest and sleep enough and provide your body with healthy fuel.
