Skinny-fat guys only get “more skinny-fat” when following a low carb/ high fat diet. Don’t do that. Keep your carbs up and your fat intake moderate. Definitely never more than 30% of your total calories, max.
No intermittent fasting right now. You don’t need any additional stress and you need to get your body temperature up.
Just eat. Wake up and have breakfast. Protein and fruit. Do that again a few hours later whenever you get hungry.
