If the scale still isn’t moving, try decreasing your protein and increasing your fat – without increasing your calories. Keep your calories at 500-600 a day, or 600-800 a day if you can’t to 500-600. Instead of four 150 calorie cans of tuna in water, have two 150 calorie cans of tuna – and add 1 tablespoon of olive oil to each can. Protein is broken down to glucose by gluconeogensis, and sometimes it helps to substitute fat calories for protein calories – so there’s less circulating glucose to facilitate fat storage.
